Hello all, we are having issues with some specific package type aluminum caps we use while running lead free. We used to run these leaded with none of these issues. Basically we are not getting more than 25% hole fill on these parts. I have tested different thermal settings and flux settings with no luck. I believe the hole size needs to be enlarged. Currently the lead diameter is 77% of the hole diameter. Is there a recommended IPC spec that would have this info I need? I can approach engineering on this but they will not be very receptive without standards. Id like to enlarge the hole so the lead is only 50%-60% of the hole diameter.
