Hello All, I recently had a case of excessive tin coming from a solder pot sample. The solder is SN63 but the results of testing had a 64.97% for Sn. The J-STD-001 spec is 61.5% to 64.5%. The pot is used to pre-tin wires which will then be solder

Robert: Consider requesting samples of different sized solder balls from a variety of suppliers, solder them to dummy boards, and compare the size of reflowed balls to your spec. Then you could buy based on results. My2� Dave F

BGA Manufacture and process control. To X-ray or not to X-ray, that is the question!!! Are there any bench top or sample inspection units avaliable with good(useable) software?? Help me SMT netters, you are my only hope. Marc

My company is an CM we are looking into refining our processes for BGA in our production line. Do you know where to obtain samples for process refinement in Australia. Scrap BGA Components and PCB's will be suitable.

Chris, Some ramblings- Your choice depends on factors like which defects you're looking for, bugdet, quality inspection philosophy, high or low mix environment, sample sizes or 100%, and so on. Are you going to test 100% of the product coming off t

Thin Film Technologies in Mankato Minnesota offers 0201 resistors. You can also talk to the people at KME as they supplied us the samples we needed to tst out the equipment.

From the manufacturer's perspective, we aim to be able to fully inspect all components within the beat rate of the line and generally do. I'm not aware of any competitive machines that do the random sampling that is suggested above, however it is do

This sounds like it could possibly be a case of Black Pad. We have had a few issuses with this in the past as well. Who the PWB vendor? I also recommend searching the archives and doing some solder samples with nonpopulated boards
