| Has anyone had the experience of losing components after they have been placed by the HSP 4796 because of table movement. I've worked on the 4760s, 4780s, and 4785. I don't know if this is a problem or not. We are trying to determine if this a poss

Wayne, Earl, I wish there was some way we could toss our wave solder machine forever! Unfortunately, we haven't found a way yet to do paste-in-hole reflow for large numbers of thru-hole axial and radial components, which we insert on Universal machi

Posted wave solder paper to library and my 2 cents on intermetallics

I dug through my big box of office crap and found the disk with my technical papers. I posted the one on process control in the SMTNet library. It covers a lot of ground on what causes defects in the wave (too much or too little of something), and

Setting up solder material evaluation (suggestions?)

Electronics Forum | Mon May 03 17:23:24 EDT 1999 | Kelly Morris

I am about to embark on an effort to evaluate 3 different solder material suppliers and their recommended materials for our assembly process, in an effort to find the best supplier/material. We do mixed technology, with NOCLEAN chemistry so I will b

We have carried out some experimental work, in conjunction with DEK. Instead of dispensing adhesive for SMD components onto the bottom side of on of our PCBs, we have looked at the possibility of screen printing the adhesive. Because, at the stage of
