Or KISS 103 seems to blown on of the Gecko Stepper drives. Anyone have a good way to replace it? There does not seem to be any good access to it. Do I need to remove the complete solder assembly to gain access?

By Hot Air Knife I assume (leave it alone Dave F.) that you mean a debridging knife located at the exit end of a wave solder machine. Russ is right, they are not a good substitute for a good process, but once the process (w/o HAK) is developed, it

Hi Gani, HASL is normally very good for solderability providing there is a good consistent coating of HASL on the pcb pad. But it is not unusual to have a very thin coating of HASL on the pad and this is poor for solderability. You then have tin/copp

Without the proper tools in house you will not be able to determine anything but the most obvious problems. At minimum, some side looking microscope that would allow visual inspection of a row or two, and to be able to rule out bridging. Using that

Steve: Several points: * I don't have any real problems with the paper that you referenced. The hair on the back of my neck did rise a bit when the paper touched-on the higher level of process control required for ENIG. * JAX makes a good point.

Ian, The vision should recognize it; given you've got the correct Part Data. To run 0402 effectively with a CP3 you need: 1. A good, I mean real good, CP4 style feeder for 0402 (1005) 2. 0.7mm nozzles (get from second-source supplier such as WT in

Process capability indices are pretty well documented. Consider: 1 A good general SPC book like: Statistical Quality Control; EL Grant & RS Leavenworth; Mcgraw-Hill; ISBN 0078443547 2 Other good books are: Statistical Process Control For SMT; WS
