First, any results of pull or shear tests are unscientific at best. [We pop our BGA from boards with, appropriately enough, a beverage can opener.] Second, we have no have problems with your ENIG specification. Third, as with your customer, we'd e

I've been informed that I can't post the Dye Penetrant paper on the SMTNET library till Advanced Packaging releases the paper in their Dec. issue. You should be able to pull a copy in the next couple of weeks from their site, http://ap.pennnet.com/ho

Hi It's me again. Our products need to pass a chamber test 45c/36hrs after the PCBA completed batch of functional tests and assemble in to case. We found 1 unit was functioning for 24hours in the chamber, but hang after that. We tried to re-boot the

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

We found a PCBA performance have insertion loss at the functional test process. We did some analysis and conclude the main root cause is from the PCB performance. What is the critical parameter in PCB will cause a failure in PCBA frequency performan

Maybe there's no test and I don't know where or why my customer came with that requirement (I think because in one of the board shipments he got a board were a smd resistor broke, but I think that happened because miss handling), but anyway I need so
