Hello friends , What is the extent of Probe mark allowed on a assembled board ? Is there any related material on net or standard .Recently we had an issue where the ICT was done and the joints on which the pins were tested had dents on the joints

I'm not aware of any such stipulation about witness [probe] marks for assembled boards, per se. Certainly, witness marks should not affect the intended performance of the assembly, you know, like damaging the solder connection or smudging solder mate

Actually, if you experience lack of witness marks, you probably have a problem. Witness marks are OK and will not affect your assembly. I assume this is an SMT assembly we are talking about, in which case, this is what your test pads are for. You

Hi Folks, When temp profiling bga rework how important is thermocouple placement. Have read that holes should be drilled from board underside into ball to accomodate probe (isn't theory wonderful). Probably ok for high volume rework but for 1 or 2 of

IPC-610 should tell you if the joint is suspect. I would tend to think they would not have any negative effect.

How deep is the indent? I would say as long as it is hitting nothing but net (the solder fill), your fine. Besides, you should notice indents on your solder fillets of components on the top-side as well. This is also expected and acceptable.

Remeber Do not use any probes or fixtures to hold the lead down while soldering or rework .....this is a bad idea. I would remove the component and replace or gently push the lead back into coplanarity and resolder. This all can be done at most rewor
