KBDFans Plate Foam Kit

This foam is designed to be placed directly between your keyboard's PCB and the mounting plate. It acts as a buffer to dampen vibrations and eliminate the hollow sound often found in mechanical keyboards.

The 3.5mm thickness is standard for many custom builds, but it may not fit every keyboard. Before purchasing, ensure your specific keyboard model has enough clearance between the plate and PCB to accommodate the foam without causing interference with your switches.

Adding plate foam effectively reduces resonance and 'hollow' pinging sounds. It results in a deeper, more muted, and solid acoustic profile, which many enthusiasts prefer over the sharper, metallic sound of an empty keyboard case.

Installation typically requires removing your switches to place the foam between the plate and PCB. If you have a hot-swappable keyboard, this is a straightforward process; if your switches are soldered, you will need to desolder them first.

Yes, the foam provides a slight dampening effect when you bottom out your keys. While it doesn't change the switch travel distance significantly, it makes the typing experience feel slightly more cushioned and less harsh.
