The only problems I've ever had with 208's shifting out of alignment was with a board with too much HASL thickness. The lands had a convex profile and the parts kept slipping downslope. We put down a glue dot and ranted at our board supplier. Both

Has anyone had issues with chips not making a reliable connection in sockets with a matte tin finish (RoHS compatible)? We have had issues with these types of sockets. I sent some to the manufacturer, and was told there weren't any problems. We re

We had the same problem with our E5. I had the shop make us a template for each two-sided board out of some 1/16" acrylic. The template had cutouts in it to drop the pins through where the bottom side parts weren't. Seemed to work fairly well, no com

I totally agree with Wolfman. I recently had the SMA responsibility for a new product from a new customer. The PCB had 600+ mounting positions. It took me almost two days insering them into the part library because an unusual number of the positions

Are you controlling humidity in your plant? I'm not familiar with that particular paste, but some pastes are sensitive to a humid environment. We also had one paste supplier send us a batch that had excessive solder balls if the boards were printed
