Hello, There is curious PCB technology used for one aluminum LED PCB. First of all there is no solder mask. PCB tracks look grainy and there is no fillet near components. Tracks near components are thicker. A kind of material has been applied to

The 4 places I've worked in SMT all had their own solutions for their own reason. I quit worrying about what worked best if what I had worked OK. I've only seen (or recognized, at least) tension issues on foils that had been saved well beyond a rea

Hi all, We were able to fix the issue. We replaced the MOT cards with the MOT cards in the good machine. That, however, did not resolve the issue. The issue was very basic; one of the fuses (fi fuse) located to the left of the MOT cards became open.

I am finding if I have to stop the pick and place machine during production very often (mostly due to feeders not pulling the tape cover back), I get paste drying in the apertures of the stencil. To avoid this I am thinking of pasting all the boards

Hey just solders and QA people don't like it. As long as management likes it, who are these to argue? Fire them all and hire people that like cameras better. Now seriously - people who work with it should have the final word. You can also have both

there is no, error $0022 in technical reference. is the error you are getting a EMER level? if so there is probably a safety sensor or switch that is causing this error. $0021 is related to door switch so I would go from there. do you have technical

You'll want to chop your solder into "bite sized" pieces for your pot, by the way. A bolt cutter or a band saw are a couple of ways to do it without ruining other precision tools. It's up to you for the alloy you use, but there are several (some

In a past life I used a Swam Blaster from Crystal Mark with the media from them as well. I used it on Humiseal 1A31 and 1B31 (I think those were the products, it's been a little while). This machine and material were awesome IMO. Made CC removal a
