I have a circuit board I'm mounting on a molded piece of ABS. It's currently mounted on molded bosses with holes that I put screws in, but the screws strip and pull out, and pulling out is bad. Stripping is bad in this case.
I want to replace the screws with pins that would be molded to the boss, so the mounting hole in the board would fit over the pin, then I'd melt the pin down to act sort of like a rivet.
It's sort of like the pins outlined in this document
(pg. 2 Mounting Instructions).
I have searched google for every combination of plastic, welding, rivets, mounting, pins, PCB, and tools I can think of and I'm not turning up quite what I am looking for.
Can anybody help me out? I want both the tool that would melt the pin, as well as a little info on how to do it right. My company hasn't ever worked with plastic before, so I'll have to give the assembly people some instruction.
BTW, this is the actual board and piece in question. I need to have them modify the mold before I approve the prototype.
