| | | | | | | Geez, those test guys are always whining about via holes, aren't they? I even had one test guy go over to our finals/add-on department and instruct everone to look for unfilled vias and fill them by hand! Without consulting the area

Well, I can't speak for them falling off later on, as that's not when I see them, and they are passing their wire pull tests after bonding. What I am seeing is electrical opens during testing, and these opens coincide with the Au/Al bonded points. Th

Hi, What's the acceptable criteria for Ion Chromatography Testing? I found a test lab but they said we have to define what is pass or failed. Can anyone guide me to the right document either IPC or MIL Std? thanks,

Won't there be ESD & inspection problems with Martins dispensed all over the board? we only have 1 Martin here and he would fail an ESD test and a cleanliness test. Also he's considerably bigger than any board we make.

Lots of papers out there on HiFreq circuits and the effects of solder paste residue. Google Dr. Karen Tellefsen. Simple test...take a "failed" board, remove the residues, test again. Has the problem gone away?

We have a Yamaha GEM and the laser will not recognise components. The laser has been changed in the past by another engineer, but this failed to rectify the problem. Can anyone advise how to test the laser or use some machine diagnostics so that I
