Any idea what the "industry standard" is for fall out on assembled PCB's? I realize that the controls put in place in your processes will effect your overall quality. But I'm trying for a general answer. On pre-tested assemblies, should you expect

Actually, it's not even close to 3/8". It's more like 0.075"...not sure what I was smoking last night (I tried to guess on dimensions from my house, and now I have one in front of me). Anyway, to answer your question, the bulge is in between side A

Hi guys, Has anyone ever had experiance with a Vision Master 150 ?, we have 2 onsite and I am trying to get accurate BGA paste height measurements from this machine, but both the machines are giving me results with huge variations, like +/- 0.2 thou

Hello Dekhead, it is a constant offset, like 0.5 mm to right when machine prints away from operator. When print goes towards the operator there is no offset. I swapped X5 and X6 cards with spares I got but still same result . I set the program to hav

Hi, good day to all. This is my 1st question post in this forum. Hope able to share some knowledge here. As we know QFP area like 0.4mm pitch was a very critical area to control especially those PCB using silkscreen printing process manufactured. Onc

Agreed. We machine all our pallets in coolant. No dust but a big mess still results in the bottom of the CNC. You'll burn through a thousand cutters if you try it on a router table. Just doesn't seem feasible. You'd have to take like 0.020" dept

Found the main problem During messing around (hopelessly :) we had found the calibration menu and pressed "check". Machine thought that there was a calibration nozzle (maybe 10x10mm square) but in reality, there was d=1.0mm nozzle. Machine decided

For a microscope, you want one with the greatest working distance and depth of field you can get. You don't want a lot of magnification, so something like 0.7 - 20 X is good. If you are buying new, have salesmen bring them by and actually try them

Sorry for delay - been flat out. Sr - I understand what you are saying. My concern is that combined with the head offsets and variations in pick points (i.e. having to teach feeder positions for very slight amounts like 0.05mm)then you cycle times wi
