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

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

Hi All, I'm hoping there is a PCB expert or two hanging around. We're having some solderability issue on our boards. The finish is ENIG but it doesn't seem to be related to the finish process itself. We did SEM and EDX analysis and found aluminum an

Emmanuel: Take Jax's word. NiAu (ENIG) primary (some would say only) redeeming characteristic is its flatness that you mentioned, but that flatness appeals to folk placing fine pitch devices, rather than BGA. Good luck. Dave F

Want to update this question a little, I know it appears few years ago, but I hope there is some updates... We have to assembly few samples of motherboards with this kind of finish (customer mistake during pcb order). Normally we can use leaded sold
