Taking the most unreliable part of a pcb (the vias) and repeated
stabbing something sharp into them has always seemed to me to be
something of a foolhardy occupation.

Subject: [TN] ICT over RoHS Via

Hi,


Is there any different within the material type of the ICT probe,
regarding the metal finishing of the PCB?
If I must use the via as a test point, do I need to coat the ENIG
annular ring with solder paste prior to reflow, in order to improve the
surface for the ICT?
Thanks

Eli.
