Title: How to Build a Quiet Mechanical Keyboard

Creating your custom quiet mechanical keyboard is not only an exciting project but also a move towards better typing comfort and a whisper-silent workspace. This in-depth guide will walk you through the entire process graphically and descriptively, starting from choosing the right parts and ending with putting everything together.

Step 1: Choose the Right Parts

Keypads

It all begins with selecting the correct keypads. There are three basic types: full-size (104 keys), tenkeyless (TKL-87 keys), and compact (61 keys). Your choice will depend on how you intend to use your keyboard. If you’ll mostly be gaming or coding, a compact keypad will suffice. However, if you often use Numpad, consider going for a full-size or TKL keyboard.

Switches

The switches determine the sound, feel, force required to press, and overall character of your keyboard. There are three types: clicky, tactile, and linear. For a silent keyboard, consider opting for linear switches like the Cherry MX Silent Red/Black or tactile switches with dampening features like the Matias Quiet Click.

Keycaps

For a quieter keyboard, thicker keycaps are better as they absorb more sound. PBT (Polybutylene Terephthalate) keycaps are thicker than ABS (Acrylonitrile Butadiene Styrene) and thus quieter. For silent functioning, consider PBT keycaps.

Frames

Frames can be plastic, aluminum, or steel. Each material affects sound. Plastic is the quietest and also the least expensive. If you prioritize silence, a plastic frame will be a good choice.

Sound Deadening Material

Materials such as neoprene or sorbothane can be added inside the keyboard case to absorb extra vibrations and reduce noise.

Step 2: Get Your Tools Ready

To build your keyboard, you’ll need a soldering iron, solder, a Phillips-head screwdriver, a wire keycap puller, and a pair of tweezers.

Step 3: Assemble Your Keyboard

Layout

Start by laying out your switches based on your keypad. A mechanical keyboard switch tester can be handy here to check that each switch works well before soldering it into place.

Soldering

Fix the switches onto your keyboard plate and solder their pins onto the PCB. Make sure that the solder points are not excessively large as they may cause short-circuiting problems. For beginners, consider practicing soldering on a cheap spare PCB first to avoid damage.

Mounting the Stabilizers

Stabilizers are used on larger keys such as Space, Shift, and Enter to keep them level when pressed. Lubricate your stabilizers to reduce stabilizer rattle, then mount them onto your PCB.

Keycaps

Fit your keycaps on your switches. Press every key multiple times to ensure there’s no key chatter and that all keys produce a consistent sound. Apply lubricant to minimize the sound of bottoming out.

Sound Deadening Material

Fix your sound deadening material inside your keyboard case to minimize the noise level of your keyboard. This is an optional step, but it significantly reduces vibrations and subsequently, the keyboard noise.

Keyboard Case

Finally, mount your PCB and plate onto your keyboard case. Then, screw the case closed with your Phillips-head screwdriver.

And voila! There’s your personalized, quiet mechanical keyboard. Whether you’re planning a long gaming session or have a major project to work on, your keyboard will cater to your needs without disturbing the silence, thanks to your hand-picked components and soft labor.

Remember, the beauty of building a custom keyboard is that you can always change any parts. It’s a continuous journey of improvement until you find the perfect fit for your typing necessitates and noise preferences.


The full version of this guide will feature comprehensive discussions and comparisons on parts, types of switches, keycaps, frames, and sound-deadening materials. It will also have detailed, step-by-step instructions with high-res images for every step of the assembly process, as well as a troubleshooting guide for any difficulties and common mistakes made during assembly.
