The Best PCBs for 75% Mechanical Keyboards

Last Updated on July 29, 2023

Welcome to our comprehensive guide on the best PCBs for 75% mechanical keyboards. If you are a keyboard enthusiast looking for the perfect printed circuit board (PCB) for your 75% mechanical keyboard build, you have come to the right place. In this article, we will cover the essential factors you need to consider when selecting a PCB for your keyboard and review some of the best PCBs available in the market today.

What Are Mechanical Keyboards’s PCB?

A mechanical keyboard’s PCB (printed circuit board) is the foundation of the keyboard that houses the electrical components responsible for the keyboard’s function. The PCB acts as a communication hub between the keyboard’s switches and the computer.

In a mechanical keyboard, each key has its own mechanical switch that sends an electrical signal to the PCB when pressed. The PCB then translates this signal into a format that the computer can understand and sends it through a USB or wireless connection.

The design of the PCB can impact the keyboard’s functionality, such as the ability to register multiple key presses simultaneously (known as “key rollover”), as well as the overall durability of the keyboard. Some mechanical keyboards allow for customization of the PCB, allowing users to modify the keyboard’s functionality and performance.

Importance of Choosing The Right PCB for a Keyboard

Choosing the right PCB for a keyboard is crucial for several reasons. First, the PCB must be compatible with the layout and design of the keyboard. This means that it must have the correct number and placement of switches, as well as support for any additional features such as LED lighting or hot-swappable switches.

Second, the PCB must be of high quality to ensure reliable and consistent performance. A poorly designed or manufactured PCB can lead to problems such as intermittent key presses, ghosting, or even complete failure of the keyboard.

Third, the PCB can have a significant impact on the overall feel and responsiveness of the keyboard. A well-designed PCB can help to minimize key wobble and reduce switch chatter, resulting in a more satisfying typing experience.

In addition, choosing the right PCB can also make it easier to customize and modify the keyboard in the future. For example, a PCB that supports open-source firmware can allow for greater flexibility in programming the keyboard and customizing its functionality.

Overall, selecting the right PCB is a critical step in building a high-quality, reliable, and satisfying keyboard.

Factors to Consider When Choosing a PCB for a 75% Mechanical Keyboard

When choosing a PCB for a 75% mechanical keyboard, there are several factors to consider:

• Layout: The PCB should be designed to accommodate the specific layout of a 75% keyboard. This layout typically includes 84-87 keys, with a compact layout that combines function and navigation keys into a single column on the right side of the board.
• Compatibility: The PCB should be compatible with the switches and keycaps you plan to use. Make sure the PCB supports the switch type you want to use (e.g. Cherry MX, Gateron) and has the right number of switch positions for your desired layout.
• Firmware: The PCB firmware should be open source and customizable. This will allow you to customize key mappings, macros, and other settings to your preferences.
• Durability: Choose a PCB with high-quality components that are built to last. Look for a board with a robust design and high-quality construction to ensure durability and longevity.
• Compatibility with other components: Ensure the PCB is compatible with other components you plan to use, such as the case, plate, and stabilizers. Compatibility issues can arise if the components are not designed to work together.
• Availability: Choose a PCB that is readily available from reputable vendors. This will ensure you can easily obtain replacement parts or additional PCBs in the future if needed.

By considering these factors, you can select a high-quality PCB that meets your specific needs and ensures a great keyboarding experience.
