Welding to a PCB
935 1 Dec 21.2019, 11:59:36

Does anyone have experience capacitive-discharge welding to a PCB?  I came across the video linked below and had a few ideas in how a similar process could benefit an application I have in mind.  I haven't had a lot of luck finding any other resources on the processes, so I was wondering if anyone knew of any application notes, or could share personal experience of any pit-falls to be wary of.  I don't really have any specific questions right now - just looking to learn more about the process.

Hi
Resistance welding to copper is do-able, but it's not an ideal material to weld to. With a PCB, you normally have a very thin layer of copper. That gives you a pretty good heat impulse into the board. Coming up with a board process that does not let loose is tricky.
