The set contains one 3.9 by 8.7-inch board, two 3.5 by 5.9-inch boards, three 2.8 by 3.5-inch boards, and five 2.0 by 2.8-inch boards. This graduated assortment allows a hobbyist to prototype a small sensor circuit, assemble a larger controller, or reserve extra material for repeated builds. Every board includes four corner mounting holes, which simplifies attachment inside an enclosure or to another panel.

A tin-plating process is applied to make soldering easier, while the basic green boards feature pre-soldered holes and plating around each connection point. The trade-off is that these are single-sided prototype boards rather than double-sided copper-clad laminate. A project requiring a ground pour on both faces or an intricate custom etched layout may need a different material.

This is a practical recommendation for students, Arduino experimenters, repair technicians, and hobbyists who want several usable dimensions without buying unrelated boards individually. The range, mounting provisions, and solder-friendly finish make it especially helpful for repeatable prototyping. Those who need copper-clad stock for etching should choose one of the copper-clad sets instead.

Multiple Sizes for Varied Prototypes

The four dimensions cover compact modules as well as roomier control boards. Larger pieces accommodate more components, while smaller boards reduce material use for simple sensors, indicators, and test circuits.

Mounting and Soldering Convenience

Pre-drilled corner mounting holes and tin-plated connections streamline both installation and soldering. These details are especially helpful when the board must be fixed securely or connected to conventional through-hole components.

10 copper-clad boards

7 x 10-centimeter size

1.6-millimeter FR4 thickness

Moisture-protected packaging

The MCIGICM 10-piece set is a focused option for makers who intend to design and etch their own traces. It carries a 4.5 rating and supplies a consistent batch of 7 by 10-centimeter FR4 copper-clad boards, a practical format for many small controllers and sensor circuits.

Pros

• Ideal for etched layouts
• Uniform board dimensions
• Moisture protection included
• Cuttable fiberglass construction
• Useful for IoT projects

Cons

• No pre-drilled component holes
• Requires separate etching process

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

Each board has copper on the front and FR4 bakelite on the back, providing the correct starting surface for an etching project. The stated 1.6-millimeter thickness gives the laminate enough rigidity for handling, while its cuttable fiberglass construction allows makers to resize a board when a project demands a custom footprint.

The principal drawback is that this is raw material rather than a ready-to-populate prototype board. Users must create and transfer the circuit layout, remove unwanted copper, drill holes, and otherwise prepare the board before assembly. That added work is a feature for custom PCB makers but a disadvantage for someone who wants to solder components immediately.

This set is best for electronics learners, custom circuit designers, and builders making repeatable etched boards. Moisture-protective packaging also helps preserve the copper surface before use. Buyers who already know their layout and enjoy a hands-on fabrication process will get good utility from the uniform batch.

A Clean Surface for Etching

Single-sided copper over FR4 creates a conventional substrate for making custom traces. Makers can cut the board to fit an enclosure and follow a layout tailored to the exact circuit they need.

Consistent Batch Dimensions

Ten identically sized boards are useful when a project will be repeated or when multiple circuit variations are being evaluated. Uniformity also simplifies planning a standard enclosure or panel footprint.

Chanzon 10 Pcs PCB Boards

10 copper-clad boards

7 x 10-centimeter size

1.6-millimeter laminate thickness

Flame-resistant fiberglass

The Chanzon 10-piece set offers a straightforward supply of single-sided copper-clad boards for etching projects. Its 4.2 rating is lower than the leaders in this guide, but the stated construction remains suitable for electrical, power, DIY, and IoT prototyping work when users are comfortable preparing the laminate themselves.

Pros

• Suitable for custom etching
• Standard rectangular dimensions
• Cuttable fiberglass material
• Moisture-protective storage
• Useful for power experiments

Cons

• Lower rating than leading sets
• Requires layout and etching work

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

The boards measure 7 by 10 centimeters and are described as 1.6 millimeters thick. Copper occupies the front while bakelite forms the reverse, and the fiberglass material is described as cuttable and flame resistant. Moisture-protective packaging is included to help reduce copper rust before the boards are used.

As with other raw copper-clad sets, this product is not supplied with a finished hole pattern. The builder must design, transfer, etch, clean, and drill the boards before components can be installed. That process is well suited to custom circuits but adds time compared with using one of the pre-drilled prototype kits in the guide.

The product makes sense for users creating their own PCB patterns, experimenting with board layouts, or producing several copies of a small circuit. It is less attractive for a first-time maker who wants a ready-made prototyping surface. Check that the listed material, dimensions, and single-sided format align with the intended fabrication process before ordering.

Useful for Repeatable Custom Circuits

A ten-board batch supports iteration, allowing a maker to refine a layout and create multiple versions. The standard rectangular shape also makes the material straightforward to measure, cut, and compare.

Material Protection Before Use

Moisture-protective packaging helps guard exposed copper from environmental damage. Keeping unused boards sealed also reduces the chance that oxidation will interfere with later preparation.

Every board measures 150 by 100 millimeters, or 5.91 by 3.93 inches, and is constructed from FR4 glass fiber and copper. The surface supports mechanical support and electrical connections for DIY IoT prototyping, while the square-ish footprint provides more working area than the smaller 100 by 70-millimeter alternative.

One important preparation step is polishing away the oxide layer with fine sandpaper before attempting a carbon-powder transfer. This is not a problem for experienced fabricators, but first-time users should follow it carefully because smooth, clean copper improves transfer reliability. The set does not include headers, jumpers, or terminal blocks.

This option is a good fit for compact custom circuits, IoT experiments, and makers who want a manageable number of relatively large boards. Its 5.0 rating and useful dimensions make it a strong alternative when a larger work area is important but a ten-piece batch is unnecessary.

More Working Area in a Compact Board

The 150 by 100-millimeter format offers a useful balance between footprint and component density. It can hold a moderately complex layout without becoming as unwieldy as the largest board in the guide.

Preparing the Copper Surface

Light sanding removes the oxide layer before layout transfer. Preparing the surface in this way helps carbon powder adhere more evenly and supports a clearer circuit image.

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

The assortment contains ten 2 by 8-centimeter boards, ten 3 by 7-centimeter boards, five 4 by 6-centimeter boards, five 5 by 7-centimeter boards, and two 7 by 9-centimeter boards. This distribution is particularly useful for small circuits, with a smaller number of larger panels available for more demanding assemblies.

All boards use 1.6-millimeter FR4 glass fiber and include four corner mounting holes. Their double-sided construction can offer more routing options than single-sided alternatives, although the product description does not specify the same plated-through-hole arrangement found in dedicated prototype boards. They are intended for analog, discrete, DIY, and DIP-style circuits.

This is a strong recommendation for students, experimenters, and repair builders who want a broad supply of pre-drilled sizes. It may not be the right choice for a project requiring a large uninterrupted surface or a bundled set of headers and terminal blocks, but its quantity and layout flexibility are difficult to overlook.

More Boards for Learning and Experimentation

Thirty-two pieces allow learners to make mistakes, test multiple layouts, or build several versions of a circuit. A large assortment also reduces the temptation to reuse a damaged or poorly planned prototype.

Flexible Double-Sided Layouts

Double-sided boards can make it easier to separate signal and power routing on suitable layouts. The standard 0.1-inch pattern also aligns with many common resistors, capacitors, headers, and DIP packages.

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

Each board measures 70 by 100 millimeters, equivalent to approximately 2.75 by 3.94 inches. The single-sided copper layer is suitable for making a custom trace layout, while the material is described as resistant to high temperature, resistant to oxidation, and resistant to deformation. That makes it appropriate for repeated soldering and handling.

The boards arrive without a finished circuit pattern, so users must perform the normal layout transfer, etching, cleaning, and drilling steps. The larger count helps when refining a design, but all pieces have the same size. A project requiring several different footprints will need to trim the laminate or select a multi-size set.

This product is a good fit for students learning PCB fabrication, technicians building compact custom circuits, and makers who expect to iterate on a layout. It provides a useful middle ground between small single-board packages and much larger assortments without including extra wiring hardware.

Room for Iterative Circuit Development

Fifteen boards allow a maker to create successive layout revisions without running out of material. This is particularly helpful while learning how component spacing, trace routing, and drilling affect the final design.

Stable Substrate for Soldering

The FR4 and copper construction is described as resistant to heat and deformation. That gives the thin laminate a stable feel during through-hole soldering and repeated bench work.

Cons

• Strip layout is less flexible
• Only three boards included

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

Each board is built from full glass-fiber FR4, and the copper foils are tin-plated to strengthen the pads. Two hole diameters, 1.0 and 1.4 millimeters, support resistors, capacitors, wire gauges, and other through-hole components. Four corner mounting holes make the 4 by 6-inch board easier to secure in a project.

A strip board provides a fixed grid rather than the complete routing freedom of a custom PCB. That makes it less suitable for dense, tightly constrained layouts, yet much faster for conventional circuits with standard pitch components. The set also contains only three boards, and no headers, jumpers, or terminal blocks are included.

This product is ideal for repair work, educational prototypes, analog and discrete circuits, and anyone building a larger temporary or semi-permanent circuit on a universal board. Choose it when immediate solderability and component clearance matter more than a bespoke copper pattern.

Dual Hole Sizes Expand Component Support

The combination of 1.0- and 1.4-millimeter holes accommodates different lead diameters and common component packages. This flexibility makes the board useful for mixed-component circuits rather than only one narrow component family.

Large, Mountable Prototype Surface

A 4 by 6-inch board provides room for several discrete components and connecting wires. Corner holes make it easier to mount the finished circuit in a project box or on a larger base.

The 1.6-millimeter FR4 construction provides a rigid base, while pre-tinned holes simplify soldering components and sensors.

The connection hardware is unusually comprehensive. It includes six 40-pin straight male headers, six 40-pin straight female headers, four 40-pin right-angle male headers, six 2-pin terminal blocks, four 3-pin terminal blocks, and 100 jumper caps. Every row uses a 2.54-millimeter pitch, creating compatibility with many standard development modules and Arduino-related projects.

This kit is best for users building complete prototype assemblies rather than a single isolated circuit. It suits makers who want multiple board sizes, removable connections, screw-terminal wiring, and Arduino-compatible spacing in one package. Some components may be unnecessary for a small project, but the breadth makes the bundle especially convenient for a well-equipped electronics bench.

A Complete Connection Hardware Bundle

Male, female, and right-angle headers support different ways of connecting a board to modules or external circuits. Terminal blocks add a practical option for attaching wires without soldering every connection directly to a header.

Six Sizes for Mixed Project Stages

The size range supports small sensor modules, medium controller boards, and larger demonstration circuits. Having several proportions available also makes it easier to prototype a system before settling on one board format.

The boards use FR4 glass fiber and copper with a 1.5-millimeter thickness. This construction provides mechanical support and an electrical connection surface for DIY IoT prototyping, models, and other custom electronic projects. The generous area can simplify layouts that would otherwise require a very small board or an awkwardly routed pattern.

Because the boards are single-sided copper-clad laminate, they must be prepared through the usual custom fabrication sequence. The surface should be polished with fine sandpaper before the carbon-powder transfer stage, and no pre-drilled hole grid or connection accessories are provided. The larger size also means more material to etch, clean, and drill.

This product is best for builders designing a spacious custom board, working on a model, or comparing several versions of a larger circuit. Buyers should confirm the actual dimensions, copper coverage, and delivery condition in the current listing. Its selection here is driven by its useful material format, not by a customer rating.

More Room for Custom Routing

A broad board can reduce crowding and make it easier to arrange larger components, test points, and longer trace runs. The extra area is especially helpful when the design must later be reproduced several times.

Verify Size Information Before Fabrication

The supplied title and product details present different size descriptions. Confirming the actual dimensions with the seller prevents an enclosure, mounting pattern, or planned layout from being based on the wrong footprint.

Each board is made from FR4 glass fiber and copper and has a thickness of 1.5 millimeters. The single-sided construction is intended for custom circuit layouts, DIY IoT prototyping, models, and similar projects. As with the other copper-clad products, it is supplied as a base material rather than a pre-drilled universal board.

The copper surface should be polished with fine sandpaper before attempting a carbon-powder transfer. Users then need to etch, clean, drill, and finish the board according to their layout. No connection hardware is included, so anyone expecting immediate use with headers or jumpers will need to obtain those separately.

This set is a good fit for compact electronics, small sensor circuits, and makers who want to try custom PCB fabrication without committing to a large sheet. Its 5.0 rating and manageable dimensions make it a strong compact raw-material choice, provided the builder is comfortable completing the fabrication steps.

Manageable for Small Enclosures

The 100 by 70-millimeter footprint is easy to trim and position in a small project box. It is well suited to simple sensor modules, indicators, and compact controller layouts.

A Practical Custom Fabrication Batch

Five boards provide room for a small development series rather than a single trial. The compact dimensions also limit waste when creating a dedicated layout for a specific device.

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

The right blank PCB circuit board depends on whether you plan to etch a custom trace pattern, assemble on a universal hole grid, or build a project around a specific enclosure and component set. Material, dimensions, layering, and included accessories should be evaluated together.

Choose the Right Board Construction

Copper-clad laminate consists of a fiberglass-based board with copper bonded to one or both surfaces. It is intended for custom layouts that require etching, transfer, drilling, and cleanup. Universal prototype boards instead arrive with a regular pattern of plated holes, making them faster to use with standard through-hole parts. The products in this guide cover both categories, so identify your fabrication method before choosing.

Choose copper-clad laminate for a finished custom circuit, and choose a pre-drilled prototype board for immediate soldering.

Match Dimensions to the Project

Board size should be based on the number and physical size of the components, not merely the longest trace. Smaller boards work well for compact sensor or indicator circuits, while control boards, connectors, and larger regulators may need more working area. Measure the intended enclosure and leave room for mounting holes, edge clearance, and wiring. If one layout will be repeated, a uniform set is easier to work with than several unrelated sizes.

Measure the enclosure and component layout first, then choose the smallest board that provides comfortable clearance.

Understand Single and Double Sides

Single-sided boards are easier to fabricate and can be sufficient for simple circuits because components remain on one face. Double-sided boards may provide additional routing options and can be useful for more complex or space-conscious assemblies. A double-sided universal board is not always the same as a double-sided etched PCB, so check whether both faces contain usable copper and how the holes are plated.

Select double-sided construction when routing space is tight, and confirm the actual copper pattern.

Check Material and Thickness

FR4 glass fiber is the dominant construction in this category and offers rigidity, heat resistance, and a stable base for soldering. The listed boards measure approximately 1.5 or 1.6 millimeters thick. Thicker material feels more substantial and resists warping, but it can require different drill and cutting assumptions than thinner stock. For most hobby projects, either listed thickness is practical.

FR4 around 1.5 to 1.6 millimeters suits most prototypes and provides a durable soldering base.

Evaluate Hole Patterns and Plating

A standard 0.1-inch or 2.54-millimeter grid aligns with many resistors, capacitors, headers, and DIP integrated circuits. Mixed hole diameters can accommodate a wider range of component leads and wire gauges. Plated holes and pre-tinned pads generally improve the soldering experience, while raw copper-clad boards need holes drilled after the layout is finalized.

For immediate assembly, favor standard spacing, plated holes, and a clear component-fit guarantee.

Consider Mounting and Mechanical Support

A board that cannot be fixed securely can create stress on solder joints and make finished projects awkward to use. Corner mounting holes are useful for attaching a prototype to an enclosure, backing plate, or control panel. Check the hole diameter and position against available screws and standoffs. Larger custom designs may also need additional slots or cutouts that must be added by the builder.

Confirm mounting-hole positions before ordering, especially for an enclosure with a fixed layout.

Count Boards and Accessory Value

A larger pack is helpful when building multiple versions, learning through iteration, or producing a small series. However, more boards do not guarantee better material if a project only requires one carefully designed layout. Kits that include headers, terminal blocks, and jumper caps can be more convenient for complete prototype assemblies, provided the included components match the planned circuit.

Choose quantity for repeatability and accessories for convenience, not simply the largest package.

Account for the Fabrication Process

Copper-clad boards require additional planning and preparation, including cleaning the copper, transferring the layout, etching, rinsing, drilling, and inspecting the result. Universal boards reduce those preparation steps but impose a fixed grid. Factor in the tools, safety practices, chemical handling, and time needed for etching. If those steps are unfamiliar, a pre-drilled prototype kit is usually the more accessible starting point.

Choose custom laminate only when you are prepared to fabricate the board and complete its hole pattern.

How to Use and Care for Your Blank PCB Circuit Boards

Before assembly, confirm that the board dimensions, layer count, hole pattern, and copper finish match the project. For copper-clad material, keep unused boards in a dry place and avoid touching the copper surface unnecessarily. Inspect each board for scratches, discoloration, and damage before transferring a layout or installing components.

When preparing a copper-clad board for etching, polish the oxide layer with fine sandpaper, clean the surface, and apply the chosen transfer method. Follow the instructions for the transfer medium and etchant, work in a ventilated area with appropriate protection, and rinse and dry the board as directed. Drill holes only after the copper pattern has been cleaned and inspected to avoid damaging finished traces.

For a pre-drilled prototype board, place components according to the circuit plan and confirm pin orientation before soldering. Keep the iron at a suitable temperature, create a clean mechanical joint, and avoid excessive heat around sensitive parts. After assembly, inspect for solder bridges, loose leads, and incorrect connections before applying power. Store completed projects in a dry environment and protect unused boards from moisture, dust, and accidental bending.

Frequently Asked Questions

What is the difference between a blank PCB and a breadboard?

A blank PCB is a rigid circuit-board substrate intended to become a permanent or semi-permanent circuit. A breadboard is designed for temporary, tool-free connections. Some blank PCBs in this guide are raw copper-clad laminate, while others are pre-drilled prototype boards that still require soldering.

Can I use a single-sided blank PCB for Arduino projects?

Yes, as long as the board has enough area, a suitable hole pattern, and the required connections. The YUNGUI 11-piece kit is described as compatible with Arduino kits, while the 174-piece set includes 2.54-millimeter headers and jumper accessories that can support common development layouts.

Do blank PCB circuit boards come with a drilled hole pattern?

That depends on the product. Copper-clad laminate options generally require drilling after the custom layout is etched. Pre-drilled prototype boards already contain a fixed grid of holes, and the strip-board option uses continuous copper strips with mixed hole sizes.

Is FR4 suitable for soldering and heat exposure?

FR4 is widely used for electronic circuit boards because it is rigid, electrically insulating, and resistant to normal soldering temperatures. The listed products are approximately 1.5 or 1.6 millimeters thick, with several descriptions specifically noting heat resistance and suitability for welding or soldering work.

Should I choose a single-sided or double-sided PCB?

Single-sided boards are simpler to etch and often work well for straightforward circuits. Double-sided boards can offer greater routing flexibility and may help in compact assemblies. Check the copper pattern and hole plating, because a double-sided prototype board and a custom double-sided etched board are not interchangeable fabrication formats.

What does 0.1-inch or 2.54-millimeter spacing mean?

It describes the distance between adjacent holes in a standard component grid. That spacing matches many common through-hole parts, including certain resistors, capacitors, headers, and DIP integrated circuits. Using a compatible board can reduce the need to bend or space component leads awkwardly.

Why should copper be polished before transferring a layout?

Copper naturally develops an oxide layer that can resist the transfer medium and cause an incomplete or uneven image. Fine sandpaper removes that layer, while cleaning away residue leaves a uniform surface for carbon-powder or other transfer methods to adhere properly.

Can I cut a blank PCB circuit board to size?

Several copper-clad products are described as cuttable fiberglass laminate, and the single-sided FR4 sets can generally be trimmed to fit a project. Use appropriate tools, support the board to prevent cracks, and wear suitable eye protection. Pre-drilled prototype boards are usually intended to retain their defined dimensions and hole pattern.

Final Thoughts on Choosing the Best Blank PCB Circuit Boards

The YUNGUI 11-piece kit is the strongest general choice because it combines four useful sizes, mounting holes, and solder-friendly plated construction. The 174-piece kit takes the lead for complete prototype assemblies with headers, terminal blocks, and jumpers, while the Rindion 32-piece set offers the best value-oriented mix of quantity, dimensions, and 0.1-inch spacing.

Prioritize the board format that matches your workflow. Choose copper-clad laminate when you want a custom etched circuit and are comfortable with layout transfer, etching, and drilling. Choose a pre-drilled board or strip board when you want to begin soldering immediately, and choose a kit with connection accessories when multiple prototype stages or Arduino-compatible projects are planned.

Finally, verify dimensions, layer construction, hole spacing, and included parts against the current listing before ordering. Inventory, availability, and prices can change, and a seller update can also resolve inconsistencies in individual product descriptions. Selecting the right substrate and project accessories in advance makes the build smoother and reduces avoidable rework.
