DeltaScan, a Teradyne fixture-less tester coarsely comparable to HP TestJet, eh? Er, wazzat what Milo [contact programmer at CTU on 24] used to hack into the key card that Richard Walsh [CTU honcho shot dead at Dupont plaza] gave to Jack [this is go

Q1: Can they be masked so parylene doesn't get underneath? A1: Your parylene applyer may be able to mask area, but in general no. This stuff is cured in a vacuum chamber to make sure that it gets into every past corner. Q2: How do you remove and re

Questions: 1. Is this a retail product sold as PCB only? Or is this in a finished chassis / case (like an external modem)? 2. Are the customers damaging only the BGA devices? Like prying them up with a screw driver? What? You can dam and fill

I've been running 90% lead-free (still have a couple components I can't get reliably in RoHS compliance) with a peak temp of about 238 C, on standard FR-4 boards. The only real problem is the pad adherence is compromised, making rework of the boards
