Hi, I am doing my master degree in flux cleaning process for flip chip assemblies and required to establish a new receipt for flux cleaning. currently, i am doing screening process for the parameters involve ; temp,pressure, surfactants, speed and a

With the costs of bar solder going through the roof manufacturers need to try to offset the dross related losses any way possible. Companies employ reclamation processes but in practice this only yields roughly 1/3 of the original cost of the solder

Hi Guys, Have you tried using a standard dish washer for cleaning PCB's with BGA's. What detergent or cleaning chemicals did you used? I wonder if it will work to clean a WS Flux PCB using the dish washer then get it rinsed by an old aqueou cleaner

Has anybody tried this stuff? I was asked about it this morning and it sounds plausible from their website, minus "The small volume of spent material can then be inexpensively shipped back to P. Kay Metal for recycling" part. Website: http://www.p

Danny, I'm hoping to hear more about this, too. I've seen it mentioned in a couple of other posts, but so far Sara G. (Foresite Inc.) is the only regular SMTNet poster that's actually seen this stuff. Really curious about residues, and what kind of f

Hi all, I will do my best to answer questions on MS2 here. I will try to check back at least every other day. The MS2 does not mix with the solder. It only reacts with the dross. It does not get down into the pumps. It was just formally anounced la

�..... their material acts as a barrier to oxidation," is wrong Mr. N. The MS2 material "consumes" oxides therefore removing the oxides from the dross by chemical reaction and releases the pure alloy. It is not a barrier and does not mix into the sol

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

To: Wave Master Larry, You are correct in one respect. There is always dross on the wave, but it is a result of oxidation of the tin and lead. It IN NO WAY POSITIVELY EFFECTS the solder process, in fact, dross trapped in the solder joint is a detri

Chunks, We have custom nozzles here in Riyadh that are designed to solder through-hole with SMT 0805 R's and C's just 0.5mm away. ERSA charged an arm and a leg for these, so I buy them from my toolmaker, Asadulah , for half the price. They come in
