I work for a small SMT contract manufacturer with a couple SMT lines utilizing both old (IP1, CP3) and newer (CP643, XP242)Fuji machines. We have an issue with an IP1 that has us stumped. One of the device locations has no power. After some basic tro

All of the IP-1's I have seen use a fixed feeder bank. No MFU's which is where the board is located for IP-II's. Jerry

It's surprising that you have that much copper. Copper contamination of leadfree is usually tolerable up to 1%. So, the copper is moving from the pad to the solder ball. Right? If that's correct, the pad requires a buffer material between it and

We discussed about applying 2 dots of glue on either sides of the LED body, but have yet to try it out. Other discussions include conductive adhesive, using fixturing with weight, different stencil aperature design, hand soldering.
