Reply to comment by LASERman71 in Space65 R3 - already dead from ESD! :( by aleksyandr

….How else do you think they shocked the pcb in the first place? They touched the metal case, which discharged to the pcb. The only way that could have happened was the pcb was touching the case.

Sorry dude, I have no time to teach you basics of electronics but:

Correctly designed keyboard (and frankly any other device in metal case) will have it's PCB ground line firmly connected to the case for multiple reasons (ESD included).

Of course some customs have a flaw when other contacts of the PCB may touch the case and this needs to be prevented but not because of ESD risk but simply just to avoid shorting circuits.

... so... basically what the person above said is one of the many to discharge the electricity first?

I'm not sure what you are trying to say and who you mean by "person above" but if you wish to take extra precautions just touch PC case (assuming it is properly grounded) or elsewhere.
