First, you must determine a few things: 1. What specific de-fluxing chemical are you going to use? Basic required determinations include the chemical�s pH, is it a VOC (if so, what is its VOC content), what concentration is the chemical used in (1

We've had a few problems with printing a flex-rigid PWB, and I'm hoping some of you could throw some opinions/suggestions my way. Our PWB is about 8" x 11" divided into two parts (side A & B) by 2 wide flex cables. Each of these flex cables is ab

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

Find out your maximum feeder loading (number of slots taken up, not number of feeders - 8mm, 16mm, 44mm, waffle packs tubes etc), and your likely long term max feeder loading (ie what is in the pipeline, or could be). Next find out your required run

The operators use SET SEQ and SET SEG. I know all about getting these wrong, because if you forget the "Q" or the "G" you get SET SE which is SET SENSOR. That REALLY messes up our BEC! But then again, I believe our BECs are all calibrated wrong anywa

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion

We didn't intend to light anyone's fur on fire [get anyone's underwear in a knot, roil the waters, have a cow man] about consultants. The Phil Zarrow wrote a useful paper that could help in evaluating paste. Here read it ... Evaluating Solder Paste

I've been using an Omrom machine for over 5 years now. I have mixed feelings about it. It has paid for itself many times over, but it needs constant tweaking. Constant tweaking is something I believe all AOI machines need, but the way our system wo
