It's a very small series. There's already a decision to redesign the board to get rid of QUAD BGA transformers. We'll replace them with 2x transformers in other packages. We'll also try to order lead-free smaller BGA's on the other side to unify th

I have a pcb with 750 plated through holes that get Holtite sockets inserted into them. I have a method of pressing in 10 sockets at a time. However, when we are done, the board has bad warpage on the X and Y axis. Does anyone out there have any t

I have a problem with solder bridging between IC leads, especially fine pitch leads. If we lessen the apature ratio and/or decrease stencil thickness, I have more of a chance for unsoldered or insufficent joints. I am looking for any information th

We've been breaking the cover tape on components from a specific supplier. I am curious what the standard is for the peel back force range, so I can better know if it is a feeder issue or component supplier. Of course the machine vendor is blaming

You may want to search on "Cover Tape", what date code is on the parts reel? I have multiple issues with cover tape sticking to the paper and not peeling back. Causes pick errors due to the part being covered. I think my problem is the parts have too

Hello all, I have a few CP43's and am struggling to find their air consumption ratings. I found that our IP3 consumes 240 Nl/min for the machine itself, and the MTU unit consumes 600 Nl/min, however Fuji's spec sheets do not list these ratings for t

Feeder calibration helps to center the window opening used during component pick-up by a machine nozzle. Once this is established, the next step would be to confirm the centering of Machine nozzle to the center of this feeder window during machine op
