We have had a similar problem here and looked to using a bar code reader system available from our pick and place machine manufacturer (Siemens) the big downside of this was that we needed to maintain a barcode database for all our components to ensu

No arguments there. I 100% agree that quality engineers can and do solve a lot of problems on the spot. I've nevern said "run an analysis as soon as you get a problem". The whole nine yard started with a solderability problem. In my previous product

There are several way to tech this. I used this machines some time ago and maybe I am rusty, but you can try two ways that I can think of: -use IC package with 4 leads from one side and 1 big from the other. You can play here a lot, for example you c

| During inspection and test we find leads which do not get soldered. Some are because of insufficient paste, but with others everything looks right. This will only happen on 1 to 2 pins, and it is not isolated to a specific type of ic or location o
