We've been using pre-printed labels on our PCB's for years, with 8 - 10 hours a week down time associated with them. Last October we put a CO2 laser marker on one of our lines. In 6 months we've had a total of 30 minutes down time. We use a 2D b

Some thing to watch out for is the cure spec for the adhesive. Will that match with your solder paste reflow spec? You will have two dissimiliar materials going through endothermic reactions at the same time. You could end up with under cured adhesiv

When the original material was developed, we worked with a team of industry experts from a minimum of four different companies. The material was validated by them, down to the last test question. So this has not, to date, been a particularly thorny

Good question Brian. I'll answer this briefly and try to get back to the subject after I get back from a meeting I have to be at shortly (sorry about that!). There are lots of ways to define this new field, but one relatively simple definition is u

Your supplier�s approach to managing process change is TOTALLY UNACCEPTABLE!!!! Now, let me get the froth back in my mouth. How in the world do we know if the residues on these "no-clean" boards are compatible with your product? J-STD-001C, para 4

Ken, The technology you are referring to is also known as return-to-web. This panelization method involves a hard tooled perimeter die and a press equipped with an air cushion. The PCB circuit is punched out and then inserted or "pushed" back into

This may help you regarding the V-Groove or scored board designs. With respect to material left, I did some experiments and found that for our process .009 of material seemed to be ideal. There was minimal stress required to break the boards apart ye
