I am looking for a way to clean solder off of QFP packages. I'm thinking a chemical method would be easy, as long as the chemistry doesn't attack the leads themselves, or the package. Any suggestions?

We heard about the Saki systems and did not receive positive feedback. They are quite fast but they miss a lot of easy defects; especially solder ones. Have you checked out a Mirtec system yet?

Hi, does anyone have any experience with common wave soldering defects using SAC305 alloy?.....i am finding a lot of what seem to be shrinkage cracks on the bottom side surface of the soldered components.....there is also a lot of directional cooling

Sal: JAX makes good points, but I�d like to think about this differently. It sounds like the poorly soldered connection is lifting the whole connector, so that termination floats on top of the solder, rather than submit to the wetting force and be

On TH parts we have been hand soldering. This last summer we purchased a Rhythm selective solder machine from RPS automation. I did a factory tour of both RPS and ACE since both facilities are about 1/2 mile from each other. In comparing the 2 c

Dave: You should see a solder smudge on the gold plating where the ball was attached, if there is (was) solder reflow during either the (1) BGA fabrication, (2) your BGA attach, and / or (3) your BGA removal. You rework will not remove the solder

Sure. Treat it like wave solder. Top side wetting is generaly harder to achieve than wave so don't over look it. On most selective solder machine, the delta-T is also something to look out for. Most move from preheat to pot. And snce the pot por
