We have a CyberSentry automatic paste inspection system for our SMT lines. I am
trying to establish warning & failure limits for each of our boards.
I would like to know if anyone has any recommendations in percentage of the
paste height, volume, and area for limits they set. The engineer said he has
used 20% for the warning limits. ( i.e. on a 6 mil stencil, 6.5 mils nominal +/-
1.3 mils (20%) )
Does this sound like a fair number?
I would like to get a feel for what other manufacturers are using for their
limits.
Thanks in advance,
