Dear People, Can anyone point me in the right direction. I am involved in manufacturing low volume (batches of 4-20) pcb's. I have been investigating Process Characterisation ref EIA/JEDEC PUBLICATION 132. For such a low volume scenario, has anyo

Dave, To do further analysis we don't have the BGAs of the batch from which we had this issue. We don't face this issue now in the current production lots. The problem got solved while trying to find the root cause. Will keep updated if it occurs ag

The "UP100 " is currently built by Speedline. However only the models UP100S (No Vision and manual adjust table ) and the UP 100MV (Vision and manual adjust table). These are batch printers not in-line. The IS model has been out of production for ab

We have recently had an incident where we feel that we have received a batch of cards from our assembly house which have by-passed their ICT operation. This has been determined by the lack of any indentations on the test pads from the sprung probes.

Since we use tons of different fluxes and chemistries we clean often. A quick trip to our batch cleaner- run one cycle.....back to the bench. We have no control just a weekly thang. When the sponge starts to deteriorate then it is replaced. Caldon

Interesting concept. Are the PCB's still coming off of the SM line one at a time, or are they being batched? It also seems as though you would need more duplicate tools since most stations are tool specific. It does make sense though because whether

We are struggling with an effective way to control our SMT processes. I'm curious as to what parameters other companies monitor in their processes and how to control the quality coming off the end of the SMT line. We are currently restricted to a b

need advice to point me in the correct direction for solution to the problem of unsoldered joints which look soldered under normal visual inspection, but when pull strength test is performed the leads are coming away from pad, no strong intermetallic
