1. A PCB plate is a metal plate connected to the PCB used in a keyboard, providing additional support and preventing bending.

2. The buttons on the keyboard are directly installed on the PCB plate, rather than the PCB board, further enhancing stability.

3. Overall, the PCB plate strengthens the keyboard and contributes to its stability.

PCB plates are commonly used in larger keyboards to provide added support and prevent bending. However, some keyboards do not utilize a PCB plate and instead rely solely on the keyboard board. Designing a keyboard without a PCB plate is an option, but the quality of the soldering will ultimately determine the stability of the switches.

Types of PCB Plate Materials

1. Brass

Brass plates are extremely hard and a popular choice for PCB plates. However, if left untreated, brass may discolor or oxidize over time. Some users also claim that brass plates can create loud, low sounds.

2. Carbon Fiber

Carbon fiber plates are highly durable, lightweight, and offer flexibility during typing, providing a bouncy feel.

3. Aluminum

Aluminum is the most commonly used material for PCB plates. It is sturdy, easy to cut, and does not bend easily on the keyboard.

4. Polycarbonate

Polycarbonate plates are made of plastic and offer flexibility and a bouncy feel when typing, but users have noted that they produce a bass sound.

Application of PCB Plates

PCB plates are primarily used in keyboards to provide additional support when placed on top of the PCB. For board-mounted switches, steel plates are used to stabilize the switches and minimize sway.

Difference Between PCB-Mounted and Plate-Mounted Keyboards

PCB-mounted keyboards have key switches directly installed on the PCB plate and are ideal for smaller keyboards, while plate-mounted keyboards use a metal plate to install key switches, making them suitable for larger keyboards and offering greater flexibility for design modifications.

When used in conjunction with keyboards, PCB plates offer essential support and stability. However, their usage depends on the size and design of the keyboard, and each type of PCB plate material offers its own unique characteristics and advantages.
