Keep them away from SM components.
Look at the surface mount type which can be P&P'd and reflowed. The ones we used stayed in during a second (inverted) reflow.

Subject: [TN] Self-clinching nut for PCB assembly

Hi Technetters

 

We have a design requires to mount about 10 self-clinching nuts on a 13*7 inch FR-4 PCB, it’s quite new to us and we are concerned a lot about adverse effect on PCB reliability.

 

Can anyone point me the right direct to investigate? What should we worried about?

 

Any suggestion is welcomed.

 

Regards,

Ivan
