These ultra-thin PCBs are often used in applications where space is limited, such as in wearable electronics or medical devices.

However, it’s important to note that these thin materials often sacrifice some rigidity and may not be suitable for all types of keyboards. While they work well for compact or flexible designs, a more rigid PCB like the 1.2 mm or 1.6 mm versions is usually preferred in mechanical keyboards for their stability and performance.

Does PCB thickness matter?

Yes, PCB thickness does matter, especially when designing keyboards or other precision electronics. The thickness of the PCB affects the overall rigidity, weight, and feel of the final product. In a keyboard, for example, a thicker PCB (like the 1.6 mm version) will create a sturdier, more solid feel with less flex during typing.

Thicker PCBs are often preferred in mechanical keyboards because they provide a more premium typing experience and reduce the likelihood of issues such as warping or bending. On the other hand, thinner PCBs (such as the 1.2 mm version) offer a lighter and more flexible feel, making them suitable for custom builds or portable devices where weight and space are critical considerations.

Are PCB switches hot swappable?

Hot-swappable PCB switches allow users to change switches without soldering. Many mechanical keyboards now feature hot-swappable PCBs, providing the flexibility to try different switches or replace worn-out ones with ease.

However, not all PCBs are hot-swappable. A PCB must be designed specifically with hot-swapping functionality in mind, meaning that the PCB must have switch sockets and a proper electrical layout to support this feature. Many high-end 1.6 mm PCBs include this option, while thinner or cheaper PCBs might not.

In summary, the choice between 1.6t vs 1.2 PCB comes down to the specific needs of your project. While the 1.6 mm PCB offers greater rigidity and durability, the 1.2 mm PCB provides a lighter and more flexible option. For keyboards, both thicknesses have their merits, depending on whether you’re looking for a more solid typing experience or a sleeker, more portable design.

When selecting a PCB thickness, it’s essential to consider not only the thickness itself but also the application and overall design goals. Whether you’re building a custom keyboard or upgrading an existing one, understanding these PCB variations will ensure that you choose the right components for your needs.
