Know before you buy
No, this specific foam is precision-cut exclusively for the FM60 H hotswap layout. It will not fit the layout requirements of the soldered PCB.
The 0.5mm thickness is thin enough to ensure that your switches still seat properly into the hotswap sockets without causing connectivity issues or excessive strain on the PCB.
Adding this PE foam typically introduces a 'poppier' and more refined acoustic signature. It helps dampen hollow resonance and creates a more consistent sound profile across the board.
No, this foam is designed specifically for a regular backspace, regular right shift, and stepped caps configuration. It will not accommodate split backspace or other non-standard layouts.
The foam is designed to sit securely between your switches and the PCB. It is held in place by the switches themselves once they are installed, so no adhesive is required.
