soldering contaminated parts

Electronics Forum | Tue Jan 13 12:13:18 EST 2004 | Pcopeland

I am having a problem soldering some thermistors, 0805 package. They appear to be comtaminated, is there a really agressive flux I could use to help solder these parts.

Ni/Sn plated parts

How old are these parts? Sn/Ni plating is very succeptable to age and everything else. They are possibly tarnished. Also, what is your peak temp in reflow? It takes about 225 230 C to get good wetting to the underlying nickel. Russ

The parts are dated Mar 20 2004. My profile hits a peek of around 232-240c and is above 225 for around 30 seconds.

Well I am clueless! I have a lead free build coming up and I am going to check to see if our parts do the same thing. I will let you know. Russ

Skewing of parts

Electronics Forum | Fri Jul 23 09:31:52 EDT 2004 | cyber_wolf

Make sure that your mesh conveyor drive chain is not jumping a sprocket tooth. This will cause the conveyor to "pop" and you will have skewed parts. I seriously doubt that it is your profile causing skew. It is more than likely something mechanical.

Losing parts in reflow

Electronics Forum | Wed Jun 13 16:09:28 EDT 2007 | rgduval

The parts were soldered in place on the first side. Any recommendations on material for this kind of fixture? I've shimmed boards off the belt before with titanium wave plows...but, I'd love to find something slightly more elegant.

I remember seeing that formula, but looking through my notes, I can't find it. My R&D group is starting to bigger and bigger parts on the bottom side. Could you please email or post that formula?
