How to Cut a Stripboard to Size?

Cutting a stripboard to size is essential when working on custom electronic projects, as the default size of the board might not always fit your design requirements. While the process may seem simple, precision is important to ensure a clean cut and a properly functioning circuit. Here’s a step-by-step guide on how to cut a stripboard efficiently:

1. Measure the Required Size

Before making any cuts, it’s crucial to measure the exact size of the stripboard you need for your project. Use a ruler or measuring tape to determine the length and width of the area you will be working with.

After measuring, use a pencil or fine-tip marker to draw cutting lines on the board. It’s essential that the lines are precise and straight. You can use the pre-drilled holes on the stripboard as a guide, ensuring that your cuts are aligned with the rows and columns of the board.

2. Prepare the Work Area

Set up your workspace to ensure that you have a safe and stable area for cutting. Place the stripboard on a flat, stable surface, such as a cutting mat or a workbench. To avoid slipping while cutting, use clamps or a vise to secure the stripboard in place.

3. Cutting Tools

Choose the right tool for the job. A few common tools for cutting a stripboard include:

Fine-toothed hacksaw: Ideal for making precise cuts through the stripboard material without damaging the copper strips.

Rotary tool (Dremel): A rotary tool with a cutting wheel can make cleaner and more controlled cuts. It’s especially useful for intricate or delicate work.

Score and snap method: For small, simple cuts, you can score the board with a sharp utility knife along the marked lines. Once scored deeply, you can snap the board along the cut line.

4. Cut Carefully

Once your stripboard is secure and you have chosen the right tool, it’s time to cut. Begin by gently sawing along the marked line. Use steady, even pressure, allowing the saw to do the work. Avoid rushing the cut, as this could lead to uneven or jagged edges. For more precise cuts, guide the rotary tool along the cutting line with steady pressure. The rotary tool can provide smoother edges, but take care to maintain control over the tool for safety and accuracy.

5. Finish the Cut

After the board has been cut, you may notice that the edges are rough or uneven. Smoothing the edges will prevent accidental shorts or damage to the board’s components.

File the edges: Use a fine-grit file or sandpaper to carefully smooth out the rough edges of the board. This step is particularly important if you are working with sensitive components or high-density circuits, as sharp edges can lead to unwanted contact with other parts.

Check the copper strips: After smoothing the edges, inspect the copper strips on the cut board. Ensure that no copper traces have been damaged during the cutting process. If necessary, you can use a small utility knife or a file to clean up any rough spots near the copper strips.

6. Cutting Strips (Optional)

In many cases, you’ll also need to cut the copper strips on the underside of the board to isolate specific circuits or prevent unwanted connections. Use a small drill bit, sharp knife, or strip cutter to make small breaks in the copper strips where needed. Carefully break the strip without damaging the surrounding area. These cuts should align with your circuit design to ensure proper functionality.

Difference Between a Strip Board and a Breadboard

While both strip boards and breadboards are used for prototyping, they have distinct differences:

Strip boards have fixed copper strips on one side, which makes them suitable for permanent or semi-permanent circuit assembly. They require soldering to connect components.

Howevery, breadboards are used for temporary circuit designs. They have a grid of holes that allow for easy insertion and removal of components without soldering. They are ideal for testing and experimenting with different circuit configurations.

What Size is a Stripboard?

Stripboards come in a variety of sizes, allowing engineers, hobbyists, and professionals to choose the right one for their projects. A standard stripboard typically measures around 100x160mm, but smaller or larger sizes are available depending on the complexity and scope of the circuit being designed. One of the most commonly used sizes for prototyping is the 95x64mm stripboard, which offers a compact but functional area for small to mid-range circuits, like:

1. 25 x 64 mm: Has 9 rows and 25 holes

2. 64 x 95 mm: Has 24 rows and 37 holes

3. 95 x 127 mm: Has 36 rows and 50 holes

4. 50 x 80 mm: Also known as the ST1 StripBoard, this is 1.97 x 3.15 in and 1/16 in thick

5. 160 x 100 mm: A common size in the United Kingdom

6. 160 x 233 mm: A standard double height (6U) Eurocard/VME size, which is 9.2 in wide, 6.3 in long, and 1/16 in thick

Stripboards are prototyping boards made from insulating material, like fiberglass or resin-bonded plastic. One side of the board has parallel copper strips that are typically spaced 2.54 mm apart.

Layout of a Stripboard

The layout of a stripboard is quite functional:

Copper Strips: One side of the board has copper strips running parallel to each other. These strips can be cut to create breaks and allow for more flexible circuit designs.

Holes: The board is drilled with a grid of holes that line up with the copper strips. Components can be inserted into these holes, and connections can be made by soldering to the copper strips.

Breaks and Jumps: To customize the circuit, you can cut the copper strips or use wire “jumps” to make connections that don’t follow the copper strips.

Difference Between Donut Board and Strip Board

Board Structure and Layout

Donut boards, also known as perfboards, have isolated copper pads around each hole, meaning no automatic connections between adjacent holes. In contrast, stripboards have parallel copper strips that connect rows of holes, allowing predefined electrical connections.

Component Placement

On donut boards, components can be placed freely without layout restrictions. Stripboards, however, require components to align with the copper strips, which can limit layout flexibility but simplify organization for linear designs.

Wiring and Soldering

With donut boards, each connection must be made manually, which increases soldering time. Stripboards reduce wiring by offering predefined connections, but cutting the strips may still be necessary for more intricate designs.

Fault Diagnosis

Diagnosing faults on a donut board is easier because each connection is made manually, allowing clear visibility of potential issues. On a stripboard, diagnosing faults can be more difficult due to the copper strips, which may cause unintentional short circuits.

What types of breadboards are there?

1. Solderless breadboard:

This is the most common type. It consists of many small jacks inside, and the circuit is connected by inserting the pins of electronic components. No soldering is required, which is convenient and fast, suitable for beginners and quick circuit construction and debugging.

There are different specifications and sizes, such as small breadboards are suitable for simple circuit experiments, and large breadboards can accommodate more components to build more complex circuits.

2. Solderless breadboard:

The function is similar to that of the solderless breadboard, and electronic components can be connected without soldering. Usually with colored marking lines or areas, it is easy to distinguish different circuit parts and plan component layout.

Some solderless breadboards also come with power bars and ground bars, which are convenient for providing power and ground connections for the circuit.

3. Multi-hole breadboard:

There are more jacks and a denser layout. More electronic components can be connected, which is suitable for building complex circuits.

Some multi-hole breadboards are also designed with special structures, such as grooves or slots, to facilitate the fixing of wires and components and make the circuit more stable.

4. Breadboard with power supply

The integrated power module can directly provide stable power to the circuit without the need to connect an additional power adapter or battery pack.

The power supply part usually has an adjustable voltage function to meet the power requirements of different electronic components.

5. Transparent breadboard

Made of transparent materials, it is convenient to observe the connection status and component layout inside the circuit, which is very helpful for teaching and circuit debugging.

The appearance of the transparent breadboard is beautiful, which can increase the fun and visualization of circuit construction.

What is a “solderless” breadboard?

A solderless breadboard (also called a solderless test board) is a method that provides convenient interconnection of electronic components without the need for soldering. ‌This breadboard consists of a series of U-shaped metal contacts that are located below the hole grid in the electrically insulating shell.

The component leads and the wire segments inserted through the holes are held under spring tension by the contacts below, thus achieving a solderless connection. Solderless breadboards are particularly suitable for electronic circuit experiments in hobby, education or development environments because they allow users to quickly and easily build and reconfigure circuits while saving the time and cost of soldering.

In addition, solderless breadboards also support the reuse of components, which is very beneficial for learning and training. However, it should be noted that although solderless breadboards provide great convenience, they do not provide a mechanically sturdy interconnection, have limited power handling capabilities, and are not suitable for high-speed circuit applications.

What are the advantages and disadvantages of a breadboard?

The advantages of breadboards are:

1. Convenient and fast operation:

No need to solder, electronic components can be directly inserted into the jacks of the breadboard for circuit connection, which greatly saves the time and workload of circuit construction.

If a connection error is found during the insertion of the component, the component can be easily pulled out and reinserted without damage, reducing the cost and risk of circuit construction.

2. High safety:

Compared with soldered circuits, breadboards do not have safety issues such as burns and electric shocks that may occur during soldering, and are particularly suitable for beginners and students.

There is no need to worry about components being damaged due to improper soldering, which reduces safety hazards in circuit experiments.

3. Suitable for beginners:

For beginners of electronic circuits, breadboard is an ideal learning tool. It can help beginners quickly understand the basic principles and connection methods of circuits, enhance the perceptual understanding of electronic circuits through practical operations, and improve the interest and efficiency of learning.

4. Easy to observe and debug:

The structure of the breadboard is relatively simple, and the circuit connection is clearly visible, which is convenient for users to observe the connection of the circuit and the layout of components.

The advantages of breadboard are:

1. Poor connection stability:

The contact between the jacks on the breadboard and the component pins may not be tight enough, and it is easy to have a virtual connection. Especially after transportation, movement or long-term use, the jacks may become loose, resulting in unstable circuit connection and affecting the normal operation of the circuit.

2. Not suitable for complex circuits:

The number and layout of the jacks of the breadboard are limited. When the number of components in the circuit is large or the circuit structure is complex, the breadboard may not provide enough jacks to connect all the components, limiting the scale and complexity of the circuit.

When there are many connecting wires on the breadboard, it is easy to have chaotic lines, which increases the difficulty of circuit debugging and troubleshooting.

3. Poor high-frequency performance:

The structure and material of the breadboard determine that its high-frequency performance is poor, and it is not suitable for the transmission and processing of high-frequency signals. In high-frequency circuits, the transmission of signals will be affected by the jacks and connecting wires on the breadboard, resulting in signal distortion, attenuation and other problems.

4. Limited current carrying capacity:

The current carrying capacity of the connecting wires and jacks on the breadboard is limited. For high-power electronic components, it may not provide enough current, causing the components to not work properly or damage the breadboard.

Conclusion:

Breadboards are an indispensable tool in the world of electronics. From experiments to troubleshooting, breadboards are an indispensable part of circuit design. They can easily handle modifications, are cost-effective, and are reusable, making them a mainstream product in the electronics field.
