Inside a Topre board
The dome-and-spring assembly changes the job
Topre boards use a rubber dome, conical spring, and capacitive sensor. That assembly gives Realforce and HHKB boards their distinct feel, so we clean them according to their construction instead of treating them like ordinary hot-swap mechanical keyboards.
Vintage boards may have uncommon construction and parts that are no longer available. We clean and carefully reassemble them. Electronics repair and replacement-part sourcing are outside this service, so detailed intake notes help us catch a mismatch before you ship.
