Drill holes or tooling holes have higher tolerances than Fiducial marks during PCB fabrication. I would certainly recommend Fiducial recognition as a more reliable approach for better accuracy. You could re-calibrate the Vision system file used for

Since you have home plated the apts and done solder reduction, I would take a look at your soldering profile. We have run into this before when running no-clean and found that reducing the initial ramp rate to the flux activation was a help in the

We want to complete an end of life build on a leaded no-clean circuit board assembly. I was asked how long the assembly can be stored for future use. Assume it is in a temperature controlled warehouse. Boards will be placed into individual ESD bags f

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

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

Is there any way to measure the copper oxide thickness on the inner layers of a PCB? I have been asked to investigate this and am not sure if it is possible. If it is, please tell me by what method, any contract labs that can do it, or the name of

I spoke to a field service rep from Universal and he also suggested cycling the power on the machine. Unfortunately this didn't help me but I see a trend. I'm still open to any suggestion. I'm wondering, should I see a bright white light when the
