Hi, I work for Nortel and here rework BGA'S we use DRS22 rework station and CRT 2000 X-ray inspection. The main problem is put again the BGA on the PCB because you need reboling the PCB and you could damage the soldermask. Talking about Air-vac is ve

I have a question about inspection, touch-up, and how far you need to go to get a product that meets the required IPC-spec. According to some reports (i.e. "New Study Reveals Component Defect Levels" by Stig Oresjo of Agilent) the average defect leve

One important thing to look at, when buying an AOI is the False Calls Rate, along with tact time of machine to inspect the PCB. Obviously, many machines can do the the work....but it's also true that each machine differ from the way it do the work. S

Dougie- We,too, have the IPC-A-600F, and the spec. refers to IPC-TM-650 test method in the back of the book. Look on page Number 2.4.22 of the test methods appendix. This outlines the procedure for determining the percentage of bow and twist,
