Jigo, We have never had a need to do internal testing on solder paste, and your paste supplier should be able to tell you what the correct operating temperature range is. All of the big names in solder paste have tight quality control and I suspect t

Hmmm.... We use our placement data from our placement machines. Gives us nuber of placements, yield of good placements and a ton of other stuff that makes our QC peoples eyes get very very big! We use Panasonic equipment ond utilize the Pana-Pro s

Sorry that I'm so late responding. Your new additon probably has 'backee stains on the floor already. Assuming we're talking about a fairly standard board assembly area, you don't need to specify air quality. 1 We specify * Particulate: Level to b

As part of our process/quality improvement review, it was raised thru' our findings that its a good mfg practice to monitor the incoming solder paste quality (as part of the indirect materials). We get one-page "outgoing QC" vendor reports with each
