What Do You Consider When Selecting Your Keyboard PCB?

When selecting a keyboard PCB, you consider the following factors:


Your choice of keyboard PCB should depend on your need for it. You can select a standard keyboard PCB for basic applications whereas a gaming keyboard PCB will serve your gaming needs.

Board Quality

You ensure you get a quality keyboard PCB by engaging qualified and experienced manufacturers.

Compatibility With Software

The majority of keyboard PCBs include configurable RGB illumination. To access these capabilities, you need to ensure they have reliable software support.

Size And Layout Of The Keyboard

You find keyboard PCBs in a variety of sizes with some small featuring 84 keys. Others include the complete keyboard layout and it’s entirely up to you to decide which one is best for you.

The Ability To Work With Mechanical Switches

For mechanical switches, you have two leg-types: three legs and five legs. It’s preferable to create or choose a keyboard PCB that works with both of these types.

Type of Connection

You can connect your keyboard PCB via USB or wirelessly through Bluetooth or Wi-Fi. You find using wireless connections the preferred choice for many.

What Are Mechanical Switches In Keyboard PCBs?

Instead of hanging over the board like the contact in the rubber holder, you directly solder these switches onto the board.

While there are different mechanical switches they share the same fundamental components of a leaf spring, slider, and another spring.

All three are within the switch casing with the switch stem that links the switch and keycap located outside the housing.

The leaf spring is a tiny metal element that looks like an inverted U.

It is positioned on the housing’s edge, with part of the U shape protruding a little from the bottom.

Mechanical Switches Found In A Keyboard PCB

Mechanical Switches Found In Keyboard PCB

A straight piece of metal that isn’t linked to the leaf spring protrudes from the housing. The leg on the side of the slider separates these two components, which are what you solder onto the circuit.

Upon slider release, the spring beneath it forces the slider up, causing the slider leg to reopen the circuit.

You can personalize the keyboard PCB by altering the spring type for initiating slider movement and metal gap closure.

The actuation force will inform you on the switches’ heaviness or lightness and thus the force for circuit completion.

You fashion heavy switches from difficult to compress springs requiring great force, while the opposite is true for light switches.

What Mechanical Switch Types Can You Employ With The Keyboard PCB?

There are various different types of mechanical switches you can employ in a keyboard PCB each with a distinct feel. Depending on how you want your switch to feel and sound, switches falls into one of three categories.

  • Tactile: On pressing down, you’ll feel a bump, but it’s absolutely silent.
  • Tactile and clicky: Possesses the click clack sound and on pressing down you feel and hear a bump.
  • Linear – Lacks bumps or sounds providing a smooth feel whichever direction you press down.

You can determine the switch by inspecting the internals where a linear switch lacks bumps on the slider’s leg. A tactile switch has a bump, but has to have a floating central section to be clicky.

When you press the switch, the floating portion collides with the switch housing bottom, causing a click sound. Switches with various actuation forces are available in each of the listed categories.

What Switch Designs Can You Employ On A Keyboard PCB?

You find two common switch designs in a keyboard PCB: 3-pin and 5-pin switches. The switch designs are not superior to one another, however mounting without a plate results in less support.

The keyboard will feel creaky and unstable due to the absence of fortification. Including a plate in your PCB construction if you type heavily or desire a very solid keyboard may be necessary.

However, a mounted keyboard PCB-mounted doesn’t need extra reinforcing plate and thus is less expensive to manufacture. You find many hot-swappable boards mainly support 3-pin switches.

 A 3 Pin Switch in Plate Mounted Keyboard PCB

A 3-Pin Switch In Plate Mounted Keyboard PCB

This is however, a non-issue when making a bespoke keyboard since you can select whatever PCB to use. You can easily purchase 5-pin switches and fit them on a 3-pin boar.

You note that the only difference between the two is the extending leg numbers. In this case, you can clip off the extra leg pairing using clippers or cutters.

What Is The Role Of A Plate In A Keyboard PCB?

After selecting your Keyboard PCB, you require a plate for support. The plate secures the keyboard PCB while ensuring an even soldering process of the switches.

You need to ensure the keyboard PCB and plate are compatible. Thus, all of the plate’s switch cutouts correspond to the keyboard PCB holes where you solder each switch.

Can You Build Your Own Keyboard PCB?

Yes, you can.

You can develop your keyboard design and present the schematics or Gerber files to a manufacturer for production. When designing your own keyboard PCB, you require three things.

  • You have to design a PCB circuit for your keyboard.
  • Come up with firmware for your keyboard ensuring driver compatibility.
  • Develop appropriate drivers for your PC to accommodate your keyboard PCB.

What Components Do You Find On A Keyboard PCB?

When furnishing a keyboard PCB, you find the following components necessary:


Diodes are electrical components that allow current to flow in only one direction.

In keyboard PCBs, diodes prevent “ghosting,” which means the board can separately identify keys when numerous keys are simultaneously hit.


LEDs are special diodes (Light Emitting Diodes) that produce light when current passes through them. In this case, electrons recombine with electron holes, producing energy as photons.

You observe that the energy needed for electrons to pass the semiconductor’s band gap determines the light intensity.

Keyboard PCBs employ two types of LEDs: discrete LEDs and SMD LEDs the latter which you directly solder to the board.


A resistor regulates the amount of current that flows across a circuit. In keyboard PCBs, you require a matching resistor for the backlight LEDs to receive the proper amount of power for brightness.

What Is The Difference Between A Regular Keyboard PCB And A Mechanical Keyboard PCB?

Regular keyboard PCBs employ a silicone membrane on which the keys rest upon pushing to send a signal to the board.

You find these boards are simpler to make and cost much less than mechanical keyboard PCBs.

A Mechanical Keyboard PCB

A Mechanical Keyboard PCB

Mechanical keyboard PCBs employ a mechanical switch for each key eliminating the need for a wide membrane.

Using a mechanical keyboard PCB offers users more audible and tactile feedback when pressing keys and more customization options.

What Keyboard PCB Sizes Are Available For Design?

Keyboard PCBs come in different sizes that you measure in comparison to a full-size conventional keyboard as 100 percent.

A 100 percent keyboard PCB incorporates provision for the numpad finding common use with desktop computers.

The most common keyboard PCB sizes are 40 percent, 60 percent, 65 percent, and 75 percent. However other percentages such as 70 percent and 85 percent are also available.

40% Keyboard PCB

This is the tiniest keyboard available. It lacks a number row, a numpad, navigation keys and function keys while employing only a small number of punctuation keys.

You need to employ one or more Fn keys to obtain the missing functionality.

60% Keyboards PCB

60% keyboards are similar to 40% keyboards but with the number row.

You still lack the, numpad and both the navigation and function keys; requiring a combination of Fn keys for missing functions.

65% Keyboards PCB

The 65% keyboards PCB is essentially a 60% keyboard PCB with a right-hand column holding the cursor and navigation keys.

These keys include the Home, End, Insert, Delete, Page up and Page down buttons, and are a common feature of newer laptops.

How Can You Layout Your Keyboard PCB?

You find many regular keyboard PCBs are typically rectangular. However, you find the following available layouts:

  • Ergonomic Keyboard PCBs: Their design reduces injury or strain during typing and offering relief to those already injured.
  • Orthogonal Keyboard PCBs: The keys on most keyboards have an equal stagger. However, an orthogonal keyboard PCB is such that there is no staggering of keys on the keyboard.
  • Split Keyboard PCBs: Employ a cable for physical separation or spacing in the board center as an ergonomic design.

What Switches Can You Employ On A Mechanical Keyboard PCB?

Depending on the switch type, mechanical switches provide precise, consistent input to fingertips. There are primarily three types of mechanical switches available.

  • Linear Switches: These switches lack tactile feedback or sound at the point of actuation.
  • Tactile Switches: You have tactile feedback at the point of actuation.
  • Clicky Switches: These have a distinct click feedback clank and tactile feedback on the point of actuation.

What Design Software Can You Employ In Designing Your Keyboard PCB?

Design software is essential in your keyboard PCB design process allowing you to test your design before implementation. You can employ one of the following design software for your keyboard PCB:

Autodesk Eagle

Eagle refers to Easily Applicable Graphical Layout Editor and is one of the best PCB design software available procured by Autodesk.

It has a simple interface allowing quick learning offering you schematic and PCB editing as well as automatic routing.


Design Spark PCB Software has unlimited access upon registration offering you capability to produce 3D designs.

You can undertake multilayer designs for closed circuits with the added feature of tutorials to help you master.


You don’t have to install EasyEDA as it provides free web-based design tools. You have access to a great schematic grabber, circuit simulator and multifarious PCB capability.


KiCAD allows you to create circuit board layouts for free using different operating systems such as Windows, Linux and iOS.

You can use a schematic and component editor, footprint selector, project manager, and Gerber file viewer with this software.

What Copper Thickness Can You Employ For Your Keyboard PCB?

You find the copper thickness of PCBs depends on the application, with thickness of 1oz, 2oz, and 3oz common.

Regular boards employing normal signal transfer are typically 1 oz with larger thickness for those conducting large currents.

You find a keyboard PCB employs copper thickness of 1 oz which translates to 35 micrometers. T

he thickness, expressed in oz (ounces) is a measure of weight.

This thickness corresponds to that you achieve when you distribute a copper ounce in a uniform layer over a square foot.

How Do You Mount Switches In Keyboards PCBs?

The process by which you mount discrete switches onto the keyboard PCB is switch mount. You attach each switch via soldering on a PCB in what you describe as PCB mounting.

However, you find keyboard PCBs where you insert the switches into the holes of a metal plate, thus called plate-mounted.

The following offers you a more intricate description of the switch mounting techniques in keyboard PCBs.

Plate Mount

In this case, you fasten the switches into a plate using retention clips to secure the switches. The plate usually consists of sheet steel though you can find employment of some other material.

You can mitigate against corrosion, by painting the steel plate. Black finds common use, though you can even use white.

PCB Mount

Solder joints between the terminals and keyboard PCB are the only thing that keeps PCB mount switches in place.

PCB mount switches usually feature anchoring pins to align the switch and prevent it from rotating while in operation.

The return spring column can extend beyond the switch’s base, aiding in pinpointing the switch on the keyboard PCB.

Some switch types come with plate clips and fixing pins, allowing their use with a mounting plate or without.

What Is The Difference Between A Soldered Keyboard PCB And A Hot-swappable PCB?

The soldered and hot swappable keyboard PCBs are both forms of mechanical keyboard PCBs.

Hot-swappable PCB

Hot-swappable PCB includes hot-swap sockets that have been installed prior. Consequently, you can install switches without having to solder or de-solder.

It’s an excellent choice when you don’t want to invest in soldering supplies while enabling you to try out different switches. A disadvantage of hot-swap sockets is their susceptibility to damage when forcefully changing the switches.

In this case, a soldering process is inevitable if you are to get them working again. You can employ both three or five-pin switches in a hot-swappable PCB.

These switch-type designs, however, require plate mounting to secure them in place.

This is because the sockets are insufficient to keep the switches in place without the plate or soldering.

Soldered PCB

When purchasing a bespoke mechanical keyboard PCB, you find it is a soldered PCB. When building your own soldered PCB, soldering your switches (usually with 5-pin connectors) is a must.

You have a plate picture to guide you where you’re uncertain. You insert each switch’s huge knob into the gaping board hold while positioning the plastic pin pairing on opposite ends.

What Materials Can You Employ For Your Plate In A Keyboard PCB?

You install the plate mount on top of the PCB for enhanced support and stability preventing the keyboard from loosening.

Not all boards have this feature, with it being the fundamental distinction between the two switch mounted setups types.

You can employ the following materials for you keyboard PCB plate:

  1. Aluminum: Aluminum plates are popular and can be found on both prebuilt and custom keyboard PCBs. While inexpensive and simple to cut, aluminum is a strong material that prevents the keyboard from flexing.
  2. Brass: Stronger then aluminium, it’s, however, susceptible to rust and tarnishes over time if not properly cared for due to corrosion.
  • Carbon Fiber: Lightweight and long-lasting, it allows for elasticity when typing or gaming, giving it a lively feel.
  1. Polycarbonate: This is a type of plastic that flexes and provides a bouncy feel in the keyboard PCB.

 Aluminum Is Very Popular In Keyboard Pcb Plates

How Much Does A Keyboard PCB Cost?

The cost of a keyboard PCB will vary with different factors including the design and board size.

A large keyboard PCB will cost significantly more than a smaller one as it requires more components.

When on a budget, you can go with a less expensive build employing clone switches, and other cheap components.

A keyboard PCB can cost anywhere from a few dollars to hundreds of dollars with custom boards attracting the highest cost.
