A number of years ago I used a Kester product called Solder Saver. It is a thick liquid that one squirts onto the dross on a hot solder pot. It separates out the solder leaving a crust of almost clean dross. Unfortunately a mask is still required. Th

1. Spec references for max allowable untinned gold near glass seal and case body? 2. Low cost mechanical dip system to facilitate tinning of DIP parts. (Low volume; currently using hand solder iron techniques to allow for max coverage without bridg

I have a customer wanting to hide the identity of a particular component on a PCB assembly. The product cannot be potted and since the PCB is the product he doesn't want to pour over that one chip for aesthetics reasons. Any ideas on ways to permanen

ASTM E 443 is a test for sulfur by Oxygen Flask Combustion. Other instruments will detect sulfur (I assume a SEM with EDS capability will pick up the sulfur). We had an addition cure silicone potting compound inhibition problem last year that was t

We have three buckets filled with leftover solder paste from our screen printing process. Kester has informed me that they no longer take paste, but only dross and pot dumpings. Does anyone know if there's someplace I can recycle this, or am I goin

It has been known that sufficient cooling after soldering is important in order to get a stronger joint during its solidification stage. And it has been so much emphasised with reflow oven. But, why many models of wave soldering machine do not come w

All y'll: I could use your input on determining when to skim dross from a wave solder pot. On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. On another hand, ov
