To folks into electronics, PCB manufacturing and/or #retrocomputing: this is a very broken membrane of an LC keyboard (M0487). Many traces are bad. I was wondering if this could be manufactured like any regular PCB. JLC apparently does flexible boards although I’m not sure if it’s the same materials. Some questions:
- How to do the black contacts (graphite?)?
- How to do the bridges?
- How to define which areas are covered and exposed (like the plug)?
- Can it be done at all?
