I'm curious what other companies are doing in their soldering area (wave/ hand solder/ solder fountain) to ensure thier employees are protected sufficiently against solder fume and lead oxides. Subsequently what it implies in terms of selecting the r

Yes, if not done correctly, you will have a mess on your hands and probably do more harm than good. It can be done, though and has gotten much more common and easier to do. If you are ordering cleaning chemicals, your supplier can guide you through

I do recommend dedicated tips and dedicated workstations. Make sure that your tips come in with no lead in the tinning. There is a new, green heat resistant table mat that is being used in the industry to identify lead free areas. If operators see gr

We have some large plated through holes, that we protect with hand placed Kapton dots before they go into the wave. Is there a better option? We are going to see if the boardhouse can put them on for us but I was curious how others are/would do this.

One more thing to think about - if placing BGA's using water sol., you must ensure they are clean and dry beneath the component post wash. A few ways to do this. Simplest is to use DI from low pressurized nozzle and hand wash them at different atta

Does any one knows where to get a plating thickness meter that can be use in the fine pitch contacts and trace in PCB application like BGA pads? If there's a hand held device at lower cost much better... Also if you can recommend companies that offer

i looked at hand held XRFs for a similar application, but the smallest surface i could find one sampled was about 3mm diamiter and there about �30k but a few companies will lend you one dor trials, would tell you the plating thickness and metalic ele

Amol, Your problem is already very isolated only one part has the problem (the part that is hand soldered) Manual cleaning is very difficult. Why are you not considering a no-clean cored solder to solder the one part and skip the manual cleaning. Do

Thanks Rob, I have samples and production quantities that we are running on leaded assemblies now. I guess my next question would be, if you are already building lead-free assemblies, how are you processing the electrolity and tantalum caps? The o

Exactly. Poor Olas is pulling his hair out over an issue that has no business being "standardized". The SMEMA guys with apparently way too much time on their hands couldn't simply stop at the communications protocol and leave it at that....they had t
