A little birdy told me that WML has just been on an extended vacation and will be back in the very near future. I'm sure he and the good Dr. could have some interesting and enlightening discussions. I am looking forward to it actually.

What are you using? I'm having a tough time finding something I used to use (Kester, seems like it had a liquidus temp. of about 265�).

Yes, a polite complaint to our board shop later and the next batch didn't have that problem at least. I'm not convinced it's an ENIG issue as there was variability panel to panel in the first place.

Two things: 1 Go to IPC and buy "TP-1115 - Selection & Implementation Strategy for A Low-Residue No-Clean Process - Provides direction to electronics manufacturers interested in adopting low residue (LR) assembly technology. It addresses the concern

So, there is a crack or gap between: * Solder and component termination. Bingo Correct? Describe: * Coarseness / smoothness of the metal on the termination underneither the crack. * Solder left on the termination. Unfortunately at 45X I can't rea

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

Carol You're asking a helluva lot if you heat a PCB to 300�C and probably more in such an uncontrolled process. I'm surprised it is not irreparably damaged or, at least, discoloured. I don't think any solder mask is designed for this temperature. W

WELL I heard rumblings from the engineering dept that they wanna try this stuff here at my place of emplyment. Im not so sure about this.I've always herd that dross is part of the solder joint and part of wavesoldering.As I said before Ive done this

Time to get more solder paste and have no clearer ideas on the matter than last time. Going through the smaller jars on Digikey these two stand out (as I think they did last time!): One's Water Soluble (that's the one I got last time) and the other

Hi!!! Thanks frieds for your advising, I have a MPM UP2000, I'm going to chek the humidity control, too I'll chek the profiles again, this plant it's located close to the beach about 1/2 mile from. However if you know some table to calculate t
