Jeff: I feel your pain. Your points about pin-in-paste stuff are well taken. Consider increasing the size of the pad containing the via. * Calculate volume of the finished via. * Multiply this volume by 2 to determine the volume of paste that mus

Larry, Bubba's correct. He is probably just reading it off of a jedec spec sheet. Of course it really depends on what machine you are using when pin one is being determined. Not that it matters, it should still only come in the T/R package one di

This has come up a number of times recently and a search for intrusive reflow or pin in hole reflow will reveal several threads. Also a good resource is the link below. From what has been stated on many of these forums and my own pre-production tes

Just curious what effect pinholes and solder voids can have on solder joints that have high current passing thru them. Also could moisture from steam sterilization (autoclaving) get inside a said solder joint and then outgas during high current, and/

| Hi all, | | We're starting up tests for pin-to-paste and, well, things could be better. We're testing different pastes and we're testing different apertures rules and, well, we're still testing. It's coming close and we're getting pretty good
