Each board is single-sided and has mounting holes at all four corners. The supplied details specifically mention tin plating, which improves solderability and helps protect the plated holes from wear during repeated assembly. The assortment includes 3.9 x 8.7-inch, 3.5 x 5.9-inch, 2.8 x 3.5-inch, and 2.0 x 2.8-inch formats, giving makers useful options for both compact circuits and larger controller layouts.

The primary limitation is that single-sided boards offer less routing freedom than double-sided alternatives. Components must be placed carefully to avoid undesirable track crossings, and a complex design may require careful planning or multiple interconnections. The largest format may also be less convenient inside a compact enclosure. Nevertheless, the range of sizes, straightforward mounting, and solder-friendly construction make this kit a sensible starting point for common hand-soldered projects.

Choose this set if you want a versatile supply of predrilled prototype boards without committing to one size. It is especially useful for students, hobbyists, and Arduino builders moving between small sensor circuits and larger control projects. For anyone needing advanced two-layer routing, one of the double-sided options may be more appropriate, but for general-purpose prototyping this YUNGUI assortment is a strong all-around recommendation.

A Useful Range of Board Dimensions

The four formats accommodate different project scales without requiring repeated cutting. Choosing the closest fit can improve component placement, reduce unnecessary material, and make final assembly easier inside a project enclosure.

Mounting and Soldering Convenience

Four corner mounting holes provide simple attachment to an enclosure or base panel. Tin-plated holes also offer a practical advantage when frequent soldering, rework, or component replacement is expected.

Cons

• No predrilled hole pattern
• Single copper layer

We may earn a commission when you buy through this link, at no additional cost to you.

The construction pairs a front copper layer with FR-4 fiberglass on the back and uses 1.6mm thickness. The material is described as cuttable, flame resistant, and suitable for etching, electrical, power, DIY, and IoT prototyping tasks. Ten boards are packed in a moisture-protecting bag, a useful detail for preserving the copper surface and reducing the risk of rust or contamination before use.

Because it is a single-sided blank, routing and component placement require more discipline than on a double-sided board. The copper is concentrated on one face, and there is no predrilled grid to speed up generic construction. It is also less convenient for a beginner who wants to install components immediately without transferring a design. These are not flaws for the intended use; they simply define the board as a customizable fabrication material rather than a ready-made assembly platform.

This product makes the most sense for builders creating repeatable custom layouts, practicing etching, or producing several copies of the same circuit. If you need a fixed size and a clean copper surface, it offers a straightforward option. For rapid prototyping without layout preparation, choose a predrilled board instead. As a general copper-clad blank, the MCIGICM set is dependable, compact, and well suited to learning the board-making process.

Designed for Custom Circuit Layouts

A continuous copper surface gives the builder complete freedom to place traces, pads, and components according to a prepared design. This makes the board better suited to permanent layouts than interchangeable breadboards.

Storage Helps Preserve Copper

The stated moisture-protecting packaging helps guard the copper against rust during storage. Keeping unused boards dry also supports smoother handling and more consistent etching results.

Cons

• Lower supplied rating
• Requires custom layout preparation

We may earn a commission when you buy through this link, at no additional cost to you.

The package includes ten boards measuring 7 x 10cm and approximately 1.6mm thick. Copper is placed on the front, with the reverse described as bakelite, and the boards are described as cuttable, fiberglass-based, and flame resistant. These characteristics position the product for etching, electrical experiments, power-related DIY work, and IoT prototyping where multiple copies of a design may be required.

The matching size is useful when building several matching devices, prototypes, or teaching examples. However, a single-sided blank does not offer a predrilled grid, and its unconfigured surface requires more planning and fabrication work. The lower rating also warrants checking recent customer feedback for details not captured in the supplied listing. None of this negates the board's usefulness, but it means the product is less compelling for a plug-and-play project.

Opt for this set if your workflow includes transferring a custom design, etching copper, and producing repeated compact boards. It is less appropriate for learners who want to start soldering components immediately without designing a layout. For repeatable custom circuits, the quantity and consistent dimensions are meaningful advantages, especially compared with buying a single experimental blank.

Ten Consistent Etching Blanks

Having ten boards of the same dimensions is valuable when developing one circuit iteratively or building a small series. Consistent stock also simplifies templates, enclosures, and repeatable drilling.

Compact Dimensions Limit Placement

The 7 x 10cm format leaves ample room for many small and medium circuits while remaining practical for handheld projects. Larger components may require a larger blank from another option.

Cons

• No mounting holes
• Copper needs surface preparation

We may earn a commission when you buy through this link, at no additional cost to you.

Each blank uses FR-4 glass fiber and copper with a thickness of 1.5mm. The stated applications include circuit boards, models, and DIY IoT prototyping projects. Although the board has no predefined holes, it is intended for users who will create their own layout, drill as necessary, and establish connections during fabrication. The five-board quantity is also convenient for prototypes, revisions, or a small production run.

Preparation is important. The product guidance recommends polishing away the copper oxide layer with fine sandpaper before attempting carbon-powder transfer during printing. This extra step improves the chances that the transferred pattern bonds consistently. The board is also single-sided, so complicated routing may become difficult without careful planning. Neither limitation makes it unsuitable for its intended role; both distinguish it from a predrilled prototyping board.

This is a strong choice for makers who want custom copper layouts in a manageable, repeatable format. It suits intermediate builders comfortable with transfer, etching, drilling, and soldering. Beginners seeking an immediately usable grid should choose a prototype or strip board, while projects requiring a larger working area may prefer the 200mm-class blank. For balanced dimensions and a five-piece set, this PCB is hard to overlook.

A Practical Middle Ground for Layouts

The 150 x 100mm format offers a useful balance between component capacity and compact size. It can accommodate a moderately dense circuit while still fitting many small project boxes.

Surface Preparation Matters

Polishing the oxide layer before printing helps the transferred carbon pattern adhere as intended. This preparation is an important part of achieving clean, consistent etched traces.

We may earn a commission when you buy through this link, at no additional cost to you.

The set contains 10 boards at 2 x 8cm, 10 at 3 x 7cm, 5 at 4 x 6cm, 5 at 5 x 7cm, and 2 at 7 x 9cm. It uses durable glass-fiber FR-4 with 1.6mm thickness and standard 0.1-inch spacing. Every board includes four corner mounting holes, while space-saving bag packaging keeps the 32-piece assortment relatively compact.

Double-sided construction is the major functional advantage. It provides more routing options than a single-sided board and can simplify crowded circuits. On the other hand, the boards use a conventional predrilled grid, so they are not intended for completely unrestricted custom trace layouts. Their stated suitability for analog circuits, discrete circuits, and DIP components reinforces their role as general-purpose soldering platforms rather than etching blanks.

This is the best budget-oriented pick for beginners, educators, and frequent hobbyists because it combines an unusually large quantity with multiple formats. It is particularly useful for teaching soldering, constructing several discrete circuits, or building Arduino-adjacent prototypes with standard through-hole parts. Choose custom copper-clad blanks for etched artwork; choose this set when a versatile, ready-to-solder grid is more valuable.

Five Sizes Reduce Material Waste

The range from compact strips to larger rectangles allows builders to select a board suited to the project. Cutting an oversized board can weaken it or leave unused material, so having several options is genuinely practical.

Double-Sided Routing Adds Flexibility

Using both sides of the board makes it easier to connect components without excessive track crossings. This is especially helpful in analog and discrete circuits with many point-to-point connections.

We may earn a commission when you buy through this link, at no additional cost to you.

All boards measure 100 x 70 x 1.5mm, or approximately 2.75 x 3.94 x 0.06 inches. They are made from FR-4 glass fiber and copper and are described as resistant to high temperature, resistant to oxidation, resistant to deformation, and convenient for welding or soldering. The supplier identifies product development, experiments, maintenance, and production among their possible uses.

As a single-sided copper-clad laminate, the board offers a clean surface for custom artwork but does not provide the immediate convenience of a hole grid. Its routing capacity is also less flexible than that of a double-sided prototype board. The stated 1.5mm thickness is slightly thinner than the 1.6mm used by many perforated boards, so builders should confirm component fit, standoffs, and enclosure clearances when dimensions are critical.

Choose this product when your project requires a consistent, durable blank and you may need several iterations. It is particularly appropriate for hand-etched circuits, repair work, and controlled DIY production batches. A beginner can use it to learn layout and etching, while a more experienced builder may appreciate having 15 matching pieces available for a repeatable build. For immediate component placement, a perforated prototype board is the better category.

Useful Quantity for Iterative Builds

Fifteen matching boards support troubleshooting, revisions, and small production runs. Keeping the same dimensions across the set also simplifies jigs and repeated assembly work.

Material Handles Soldering Heat

The stated high-temperature resistance and deformation resistance support use around common soldering work. Proper temperature control and standard ESD-aware handling remain sensible practices.

• Larger than very compact boards

We may earn a commission when you buy through this link, at no additional cost to you.

The boards use full FR-4 fiberglass with tin-plated copper foils. The plating is intended to strengthen the copper strips and help prevent pads from detaching during soldering. Each board offers both 1mm and 1.4mm hole diameters, accommodating resistors, capacitors, selected American or Standard Wire Gauge conductors, and other electronic components. Four mounting holes at the corners make integration into a larger assembly straightforward.

The supplied information also lists LCD modules, optoelectronic displays, potentiometers, LED displays, integrated circuits, diodes, and transistors among possible applications. Its main limitation is that a strip board still constrains placement according to its grid. Although it is more durable than a solderless breadboard, it does not provide the unrestricted copper routing of a custom etched board. The large 4 x 6-inch format also needs adequate space in the final project.

This is the best premium pick for builders who value a ready-to-solder board with a generous layout and durable plated connections. It suits permanent analog circuits, discrete-component projects, educational demonstrations, and prototypes that need stronger mechanical support than a breadboard. Choose a custom copper blank for intricate routing, but choose this strip-board set when reliability, convenience, and immediate assembly are the priorities.

Tin Plating Supports Repeated Soldering

Tin-plated copper foils are intended to withstand soldering better than untreated surfaces. The plating also helps keep pads attached, making the board suitable for circuits that will be maintained or revised.

Two Hole Diameters Broaden Compatibility

Mixing 1mm and 1.4mm holes makes it easier to install components with different lead sizes. The varied pattern also provides useful placement flexibility within the strip-board layout.

The kit includes 11 double-sided boards across six sizes: one 9 x 15cm board, two 7 x 9cm boards, three 5 x 7cm boards, and five each of 4 x 6cm, 3 x 7cm, and 2 x 8cm boards. The 1.6mm FR-4 boards have pre-tinned holes and four corner mounting holes. Connectivity hardware includes six 40-pin straight male headers, six 40-pin straight female headers, and four 40-pin right-angle headers, all on 2.54mm pitch.

It also provides six two-pin terminal blocks, four three-pin terminal blocks, and 100 jumper caps at standard 2.54mm spacing. This broad inventory allows a builder to organize power connections, create removable links, and connect modules without sourcing every small part separately. The trade-off is that some accessories may go unused in a simple circuit, and the predrilled grid still cannot offer the full freedom of a custom etched layout.

This is the editor's choice because it combines versatile hardware, multiple dimensions, and a complete accessory set in one coherent package. It is an excellent choice for students, educators, Arduino experimenters, and anyone who wants to transition from temporary breadboards to soldered prototypes. For a single tiny circuit, a smaller board pack may be more appropriate, but for varied project work this kit minimizes the need for repeated extra purchases.

Accessories Cover Common Connection Needs

Male, female, and right-angle headers support different board-to-board and module arrangements. Terminal blocks provide secure connection points, while 100 jumper caps support standard 2.54mm prototyping layouts.

Six Sizes Support Expanding Projects

The range from compact boards to a 9 x 15cm panel makes it possible to build small sensors, control boards, and larger integrated prototypes. Corner mounting holes make each board easier to install permanently.

The Five-Piece 200 x 200mm FR-4 Copper Clad Laminate is intended for larger custom circuit designs. The title identifies a 200 x 200mm format, while the supplied size bullet states 200 x 150mm. That discrepancy is important for anyone fitting the board into an enclosure, and buyers should confirm the actual measurements on the current listing before cutting or drilling.

Pros

• Large custom working area
• Five matching copper blanks
• Durable FR-4 glass fiber
• Suitable for detailed layouts

Cons

• Conflicting dimension details
• No supplied customer rating
• Single-sided construction

We may earn a commission when you buy through this link, at no additional cost to you.

Beyond that inconsistency, the product provides five single-sided boards made from FR-4 glass fiber and copper with a thickness of 1.5mm. The generous surface area gives a builder room for more components, longer traces, larger connectors, or a custom layout that would be cramped on smaller blanks. The stated applications include circuit boards, models, and DIY IoT prototyping projects.

The board offers a continuous copper surface rather than a predrilled grid, making it suitable for transferred or etched artwork. The supplier recommends polishing away the oxide layer with fine sandpaper before printing to support carbon-powder transfer. Its single-sided layout and the uncertain dimensions limit convenience, while the lack of a supplied rating makes direct comparison of customer feedback more difficult.

Choose this option for a large custom project after verifying the real board dimensions. It may be particularly useful for a densely laid-out IoT circuit, a model with several modules, or a prototype intended to become a more permanent assembly. If enclosure space is tight, the clearly specified 150 x 100mm or 100 x 70mm sets may be safer. As a large fabrication blank, it offers useful capacity, but careful specification checking is essential.

Extra Area Supports Larger Designs

A large copper surface can accommodate more components and a more elaborate layout. It is useful when a small prototype board would force crowded placement or excessive trace routing.

Verify Dimensions Before Fabrication

The listing title and supplied specifications describe different dimensions. Confirm the actual measurements before ordering, especially when planning mounting holes, connectors, or enclosure clearances.

Pros

• Compact custom board size
• Five matching blanks
• Straightforward transfer preparation
• Useful for compact projects

Cons

• Single-sided routing
• No predrilled mounting holes

We may earn a commission when you buy through this link, at no additional cost to you.

Each board measures 100 x 70mm, equivalent to 3.93 x 2.76 inches, and is 1.5mm thick. The FR-4 glass-fiber and copper construction supports mechanical strength and electrical prototyping. As a single-sided blank, it is intended for custom artwork, etching, drilling, and soldering rather than immediate placement onto a universal hole grid.

The same preparation note applies as with the larger copper-clad products: lightly polish away the copper oxide layer with fine sandpaper before carbon-powder transfer. This helps the printed pattern adhere effectively. The main practical constraint is the board's available area, which may be tight for dense modern components, and the lack of predrilled mounting holes means final mounting must be planned. Single-sided routing also requires attention to trace crossings.

This is a strong selection for builders making compact custom circuits and for anyone who wants several matching boards without moving to a much larger format. It works well for small sensor controllers, simple power circuits, and custom modules. Choose a predrilled strip board when you need immediate component placement, or select the 150 x 100mm blank when the design needs more room. For compact etched layouts, this set is precise and versatile.

Compact Size Fits Small Assemblies

The 100 x 70mm footprint is easier than a large panel to fit inside compact project cases. It remains large enough for a meaningful collection of small and medium components.

Five Boards Support Development

Multiple matching blanks let a maker test corrections or create several versions of the same compact circuit without changing the fabrication dimensions.

Buying Guide – How to Choose the Best Blank PCB Circuit Boards

The right blank depends on how you intend to create the circuit. Board size, copper configuration, hole pattern, thickness, and included hardware should all reflect your fabrication method, component inventory, and need for a permanent or reusable prototype.

Choose the Correct Board Category

A copper-clad laminate is the right choice when you plan to transfer a custom layout, etch the copper, and drill the board yourself. A predrilled prototype or strip board is more appropriate when you want to place components and solder connections without creating artwork first. Breadboard-style grids make repeated experiments convenient, while strip boards provide a more permanent alternative with a prescribed copper pattern. The products in this guide span both categories, so identifying your process before comparing dimensions prevents an unsuitable purchase.

Match Dimensions to the Project

Board dimensions should reflect the number and physical size of components, connector spacing, mounting requirements, and available enclosure space. Compact blanks such as 100 x 70mm work well for small circuits, while 150 x 100mm and larger panels offer more room for dense layouts. A mixed-size assortment is valuable when one project box or course may involve several scales. Also account for the space needed around components for soldering, cable routing, and mechanical fasteners rather than comparing only the component footprint.

Understand Single- and Double-Sided Construction

Single-sided boards place copper on only one face, making them easy to etch and suitable for many straightforward layouts. Double-sided boards allow connections on both faces, which can reduce routing conflicts and make more complex circuits easier to assemble. Double-sided construction does not remove all trace-crossing limitations, but it provides substantially greater placement flexibility. Choose single-sided material when your layout is simple or you specifically want a one-sided etching process; choose double-sided boards for crowded analog, control, or module-heavy circuits.

Check Hole Spacing and Pattern

Prototype boards commonly use 0.1-inch, or 2.54mm, spacing, allowing standard headers, resistors, capacitors, and many integrated circuits to fit. Strip boards may include additional hole diameters for different lead sizes, while copper-clad blanks generally have no fixed grid. Confirm that your components match the stated pattern before ordering. If the project uses modules with specific header spacing, bring those dimensions to the selection process and verify that the board provides enough unbroken rows and columns around the connectors.

Evaluate FR-4 Thickness and Durability

The products here use glass-fiber FR-4 material with stated thicknesses of 1.5mm or 1.6mm. Thicker boards generally feel rigid and resist bending, which helps during soldering and mounting. If a board will be installed on standoffs, fitted into an enclosure, or subjected to repeated handling, confirm that its thickness matches the planned hardware. Copper-clad blanks also require consideration of cutting and drilling methods, because unsupported drilling can damage the material or create rough edges.

Look for Soldering and Trace Features

Tin-plated copper and pre-tinned holes can improve solder flow, protect copper from oxidation, and reduce pad wear. These details are particularly useful for permanent circuits or boards that will be revised. On unplated copper-clad laminate, proper cleaning and surface preparation become more important. The supplied instructions for one copper-transfer workflow recommend polishing away the oxide layer with fine sandpaper before printing. For repeatable results, follow the preparation method appropriate to the board and resist material being used.

Assess Included Accessories

A complete kit can be more useful than a large stack of identical boards. Headers provide connections to development modules, jumpers create temporary links on standard grids, and terminal blocks offer practical wire attachment points. The 174-piece kit includes all three categories, making it suitable for mixed Arduino-style projects. If you only need one small circuit, however, extra accessories may go unused. Compare the board quantity and dimensions against the accessories you genuinely need rather than treating the largest total count as automatically best.

Confirm Quantity, Packaging, and Specifications

Multiple boards are useful for revisions, classroom exercises, and small batches, while individual dimensions must be consistent across the set. Protective packaging can help preserve copper-clad blanks before use. It is also important to read the listing closely when specifications conflict. The 200 x 200mm product included in this guide has a title that differs from its listed bullet dimensions, making confirmation essential before fabrication. Check the current listing, included quantity, thickness, hole details, and mounting features before finalizing a purchase.

How to Use and Care for Your Blank PCB Circuit Boards

Begin by preparing the board according to its format. For a copper-clad blank, clean the copper surface and remove the oxide layer with fine sandpaper before applying the transfer method required by your artwork process. For a prototype or strip board, confirm the hole spacing and component fit, then lightly clean the pads. A clean, dry surface improves solder adhesion and reduces the chance of accidental electrical bridges.

Design or plan the layout before making permanent modifications. On etched boards, use the board dimensions to constrain the artwork and create adequate clearance between copper features. On grid-based boards, arrange components for short connections and keep sensitive analog paths away from noisy switching sections. Drill carefully when required, remove debris, and inspect the board for damaged pads or copper before soldering.

Solder with controlled heat and good ventilation, especially around connectors, terminal blocks, and larger components. Avoid leaving the iron in one position longer than necessary, and inspect each joint for a clean connection. Mount boards using their corner holes where provided, but do not overtighten fasteners that could stress the FR-4. Store unused copper-clad boards in a dry, protective package and keep the surface free of dust, moisture, and fingerprints.

Frequently Asked Questions

What is the difference between a blank PCB and a prototype board?

A blank PCB usually means a copper-clad laminate that the builder designs, transfers, etches, drills, and solders according to a custom layout. A prototype board already has a regular grid of holes or copper strips, allowing components to be placed and connected immediately. The first offers maximum layout freedom but requires more preparation; the second is faster for experimentation and hand-built circuits.

Are single-sided blank PCB circuit boards suitable for Arduino projects?

They can be, provided the layout is designed around one copper layer. Many Arduino-related modules use 2.54mm headers, and those connectors can be fitted to a suitably sized board with proper spacing. Double-sided prototype boards are generally easier for crowded layouts because they permit more routing options. A single-sided board is most attractive when the circuit is simple or a custom etched result is preferred.

Does the PCB thickness matter when building a circuit?

Yes, particularly when the board must fit a standoffs, connector, enclosure, or existing mounting hole. The featured boards use either 1.5mm or 1.6mm FR-4, and that small difference can affect alignment. Thickness also affects rigidity during soldering and resistance to bending. Measure the available space and compare it with the stated board thickness before drilling or mounting.

Do I need to polish copper before transferring a PCB design?

For the products whose supplied instructions recommend it, yes. Fine sandpaper can remove the thin oxide layer that may prevent toner or carbon powder from adhering properly. After polishing, clean away residue and avoid touching the copper with oily fingers. The exact preparation method should still match the transfer material and process you are using.

What hole spacing is standard for most prototype boards?

A 0.1-inch pitch, equal to 2.54mm, is the standard used by the featured prototype and strip boards. It supports common resistors, capacitors, ICs, headers, and jumpers. Some strip boards also include a second hole diameter for alternative component leads. Verify the actual pattern when a circuit depends on a particular component footprint.

Is a strip board better than a breadboard for permanent projects?

A strip board is usually better for a project that will remain assembled because components and connections are soldered directly to it. It is more mechanically stable than a solderless breadboard and can be mounted in an enclosure. Its copper pattern is less flexible than a custom etched PCB, so very dense layouts may be difficult. It remains a practical middle ground for permanent educational, analog, and discrete-component builds.

How many blank boards do I need for a prototype project?

One is often enough for a straightforward build, but multiple boards are valuable when a design may need revisions or when you want several matching units. Mixed-size packs can cover several projects with different footprints. Copper-clad sets are especially useful for practicing etching or producing a small batch, while large mixed kits work well for classroom work and varied Arduino-style experiments.

Can I use blank PCB circuit boards for power projects?

The supplied descriptions identify several copper-clad boards as suitable for power DIY projects, but the actual circuit requirements still matter. Component spacing, copper paths, thermal behavior, insulation, and safe clearances should be planned carefully. Do not assume a general hobby board is appropriate for mains or high-energy systems, and use appropriately rated components and protective measures for any power application.

Final Thoughts on Choosing the Best Blank PCB Circuit Boards

The best overall project system is the 174-Piece PCB Circuit Board Prototype Kit because it combines six double-sided board sizes with headers, jumper caps, and terminal blocks. The Rindion 32-Piece Set is the strongest budget-oriented choice for builders who want multiple sizes and standard 0.1-inch spacing, while the YUNGUI 4 x 6-Inch Solderable Strip Board stands out as the premium option for immediate, permanent-style prototyping.

Prioritize the board category that matches your workflow. Use copper-clad blanks for etched custom layouts, predrilled FR-4 boards for immediate soldering, and strip boards for permanent circuits built from standard components. Size should be based on component count, mounting needs, and enclosure clearance rather than appearance alone, and hole spacing must match the hardware you plan to use.

Before buying, verify the current listing details, especially dimensions, thickness, package quantity, and whether the product includes headers or other accessories. Ratings can change as more customers review a product, and prices and availability also fluctuate. Comparing the latest listing with your project requirements is the safest way to select the right blank PCB circuit boards.
