Indium got back to me with the attached PDF. I always assumed, that in order to avoid thermal shock, there could not be any more than 80 degrees C difference between the solder pot and the pre-heated board. However, it would seem that any thing le

Hi all, Is it normal for some of the small nozzles to be rejected by the wide view camera? Every time I do a nozzle centering the narrow view camera shows green circles for nozzles 1,2,3,4. The larger ones (5 and 6) show the asterisk. The wide view c

I hope that we have not lost much quality, but am still bothered by the way our select x is working. It seems to do very well when I can get the nozzle head within 5/1000 of an inch to the board as it passes. However, when I increase that distance

No, we didn't do the test you mentioned, but did EDS on the joints and didn't see carbon their (which would indicate the presence of any organic-based contaminant). For the customer the issue was closed and passed to the board shop. We did work with

PCB Storage and FIFO

Electronics Forum | Tue Sep 23 13:08:26 EDT 2008 | slthomas

Put the new stuff in the back and pull from the front. A pass through from stores makes that a lot easier. Bar codes are a wonderful thing if you can get people to use them. Wand it into stores then wand it sequentially into production via a queue.

Sure. Here's what you should do to apply repeatable amounts of flux on BGA during rework: * Squirt some gel flux on a plate or something like that that has a flat bottom and raised sides to corral the flux. * Cut notches into one edge of an old credi
