Is there silk screen on the pads? Other than that I would look for what has recently changed. Running smooth for a year and now all the sudden a problem. New microscopes always seem to do this trick as well. Amazing all the "defects" one can fi

Does anyone have experience of using a stainless Fine Grain SMT stencil for the purposes of applying ink to bare PCB's? We are exploring the possibility of getting a stencil to apply a letter that reflects the revision to each of 25 PCB's in a panel.

That is the rub here, isn�t it? For those posting, it�s easier [but much slower] to start a new thread than to search the archives. [And posters could view their issue so unique and novel that it could never have been discussed several years earlie

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

Hi, From a Manufactures choice - Green is the best due to it is the most commonly used mask color in the industry & cheapest. Kind a like Red paint for Barns. For US shops, most only have one LPI machine and to continually switch from Green to othe
