So much for the experts you asked for, Dreamer. Your project is fairly common. As an expample, there was a thread in the past month or two on SMTnet, where someone was looking for suppliers of "adapters". You should focus on: * Placing the adap

Like I said it was only a rumor I heard but intrigued me enough to play around with it one day. The lambda wave worked better than the chip wave did with makes me believe it was the surface tension of the solder not melting the already soldered parts

Phil The TIME predicament you talk about is something we "consultants" deal with every day. We certainly understand the issue. Interestingly, some of us think that TRUE root cause thinking WILL NOT OCCUR until or unless it is driven from the BOTTO

Fresh paste from a factory sealed container. Should paste be scrapped out altogether if left on the stencil for too long (length-of-time?)? Our paste is Multicore CR39. Multicore reccomended the print chamber be around 22C @ 50%-60% RH. Our plant is

The Smart Sonic 440-R SMT detergent is certified safe and effective by the EPA (I downloaded the documents from their web site). Is this true of the other chemistries that you referenced? If so, where can I find the documentation? If not, why not?

DO NOT Mix Technologies.... If you are using a no clean solder paste use a no clean wave solder process. I have direct experience with using a no clean paste and a RA water-soluble wave solder process. When cleaning with the water wash system your

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder
