In answer to your questions. (1) pls can any body throw some light on the reflow profiling? Reflow profiling is the process of confirming that you PCB's that pass through your reflow oven are produced within specifications provided by solder paste

Yes, you need to use "dedicated feeders" and only make changes when you run out of a part. It may even be better if you could convince the stock room and keep stock for those parts right on your line. The environment has to be proper for that though,

Hi Rick, Last year I've test about 15 different solder paste. To procede, I've started with different tests listed in different brochure including IPC. At the biginning, I had 15 different tests to do and at the end ( for the last 7 product ) I've

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

Hello JB, Based on the double sided assemblies, the misprint cleaning process can demand the cleaning system to remove both raw solder paste from the misprinted side of the board, and, reflowed flux residues from the assembled side. Recognizing and

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)

Hi, MYDATA's are ok for lower volume, and they are very flexible. If you only have 1 or 2 trays of components and are on a tight budget, then you can even place the trays on the Y wagon behind the PCB so you can get away without the tray wagon. Al

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

I would agree with you there, but I am only a shift supervisor. I am do not actually work in the maintenance department, although I do perform many repairs to the machines. So I've learned quite a bit on my own, and it was only recently that I was sh
