Building a Custom Mechanical Keyboard A Comprehensive Guide

Do you spend countless hours typing away on your computer, only to end up with cramped hands and a sore wrist? Or perhaps you’re a gaming enthusiast looking for the perfect keyboard to enhance your gameplay experience. Whatever your reason may be, building a custom mechanical keyboard can offer a solution to all your typing and gaming needs.

As an expert article writer, I have extensive knowledge and experience in the world of mechanical keyboards. In this long-form article, I will guide you through the process of building your very own custom mechanical keyboard. From understanding the basics to choosing the right components and assembling them, this article covers it all.

The Basics of Building a Custom Mechanical Keyboard

Before diving into the details of building a custom mechanical keyboard, let’s first understand what exactly it is. Unlike traditional membrane keyboards, mechanical keyboards use individual switches for each key. These switches offer a tactile and audible feedback, making typing and gaming a more satisfying experience.

What You Will Need

  • Keyboard PCB (Printed Circuit Board)
  • Switches
  • Keycaps
  • Stabilizers
  • Soldering Iron
  • Solder
  • Desoldering Pump
  • Tweezers
  • Screwdriver
  • Lubricant (optional)
  • Keycap Puller (optional)

Choosing the Right Components

Building a custom mechanical keyboard gives you the freedom to choose each component according to your preferences. Here are some things to consider when selecting your components:

Keyboard PCB

The PCB serves as the backbone of your keyboard and houses all the electrical connections. When choosing a PCB, make sure it is compatible with your desired layout and supports the type of switches you want to use.


Switches come in various types such as linear, tactile, and clicky, each offering a different typing experience. It is essential to research and try out different switch types before making a decision.


Keycaps are what you see and touch when typing on your keyboard. They come in different profiles, materials, and colors. Consider the keycap profile that offers the most comfortable typing experience for you.


Stabilizers are used to keep larger keys such as the spacebar and shift keys stable while typing. Make sure to choose high-quality stabilizers to avoid any rattling or wobbling of keys.

Assembling Your Custom Mechanical Keyboard

Now that you have all your components ready, it’s time to assemble your custom mechanical keyboard. Here’s a step-by-step guide:

  1. Begin by soldering the switches onto the PCB. Use a desoldering pump to remove any excess solder on the switch pins.
  2. Install the stabilizers onto the PCB, making sure they are securely attached.
  3. Place the keycaps on top of the switches and press down until they snap into place.
  4. If desired, lubricate the switches to improve their smoothness and reduce noise.
  5. Connect the keyboard to your computer and test each key to ensure they are working correctly.
  6. If any issues arise, use a multimeter to check for any faulty connections and fix them accordingly.

Using Your Custom Mechanical Keyboard

Comparing Custom Mechanical Keyboards to Traditional Keyboards

The debate between custom mechanical keyboards and traditional membrane keyboards is ongoing. However, here are some key differences that set them apart:

Custom Mechanical Keyboards Traditional Keyboards
Offers tactile feedback and customization options Lack of tactile feedback and limited customization
More durable and long-lasting Prone to failure and need frequent replacement
Quieter typing experience (depending on switch type) Louder typing experience

Advice for Building Your First Custom Mechanical Keyboard

Building a custom mechanical keyboard can be overwhelming, especially for first-timers. Here are some tips to keep in mind:

  • Do thorough research and familiarize yourself with the components and their compatibility.
  • Take your time and be patient while assembling your keyboard to avoid any mistakes.
  • Invest in high-quality components to ensure a smooth and long-lasting typing experience.


Q: How long does it take to build a custom mechanical keyboard?

A: The time taken to build a custom mechanical keyboard varies depending on your level of experience and complexity of the build. It can range from a couple of hours to a few days.

Q: Can I change the switches on my custom mechanical keyboard after assembling it?

A: Yes, you can desolder the switches and replace them with different ones if desired. However, this process can be time-consuming and requires proper equipment and knowledge.

Q: Are custom mechanical keyboards worth the investment?

A: While they may be more expensive compared to traditional keyboards, the customization options and durability make them a worthwhile investment for those who use their keyboards frequently.

Q: Can I use a custom mechanical keyboard for gaming?

A: Absolutely! Many gamers prefer using custom mechanical keyboards due to their customizable features and faster response time.

Q: Is it possible to build a custom mechanical keyboard without any soldering experience?

A: While some kits offer hot-swappable sockets, allowing you to change switches without soldering, most custom mechanical keyboards require some level of soldering. It is recommended to have some experience or seek professional help.


Building a custom mechanical keyboard may seem like a daunting task, but with the right components and knowledge, it can be a fun and rewarding experience. By following this comprehensive guide, you can create a keyboard that not only offers a unique typing experience but also reflects your personality and preferences.
