I wouldn't recommend a metal squeegee, because if you can't wipe the step-etched area completely clean (that's the problem with metal) you'll have problems with the definition of the fine-pitch (it may stick in the holes). Best is a 70 Shore polyuret

Does anyone reliably place 20 mil pitch QFPs with a zevetech 570laser upgraded to 575 with a VCS camera vision system? Different spec sheets seem to conflict with each other, and even the people at juki have given me different specs. If anyone has an

Our company has had one of these machines and it worked ok. It is my understanding that the upgrade to a 575 allowed it to go down to 15mil pitch. Although I have never tried it. I would call their North Carolina office and ask to speak with Rick

Shelf life dates are normally conservative. Years ago we would "requalify" adhesives by running lapshear tests. Don't know if Loctite has a "requalification" test or not. I do know that we have used Loctite chipbonders that were over a year out of
