We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

A laser cut stainless steel stencil was used exclusively for the evaluation of the complete 0201 assembly process, which addressed printing, placement, and reflow. However, I have also conducted off-line 0201 print tests using a nickel electroformed

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

We use JUKI KE2060 now, and we consider purchase of two YS12 for our next assembly line. But I'm afraid some of the details, like lack of pick-hight measurment function in YS12, we got used to perform at the begining of new production run (by JUKI's

And why do you want to control the process? To prevent defects, I would think. Actually orginally the way I first saw SPC was to reduce inspection. If you are using SPC for plating thickness, you don't have to measure every piece to be confident the

The results from an experiment comparing 27 different combinations of pad dimensions concluded that the pad design with 15 mil pad length, 12 mil pad width, and 9 mil pad separation produced the best assembly yields. A 5 mil thick laser cut stencil

What methods do you guys use for maintaining lot and/or board traceability? When I worked in med. products, we used travelers that we recorded everything on, then serialized them at the end of the build. Not as effective as up front serialization,
