lint from what?...also roughly how often do you clean the oven? (not the heated chamber) but other areas to keep them clean? The operator say he has had to do it twice in 2 weeks to keep it clean due to the residue

I guess the first thing to look at is the temperature. We had to heat more for QFP256 on sample boards and we saw discoloration on some small parts. Just try to sense around when profiling to see what's there.

Temp stickers work fine but a temp profiler gives you more useful data. The topside temp depends on the type of flux you use Look at the flux spec sheet or ask your flux supplier. Patrick

This is true but even the so called reworkable underfill takes a lot of effort. We use a loctite reworkable that requires heat to soften the underfill. Once the component is removed we use acetone and a swab to scrub the pcb clean. This can be very t

I am sorry, but I hope No hard feelings? :) As for an answer to Your question: No I can not see the reason for using three heat zones on the wave. Anybody else?

Yeah, and I would love to see a data sheet on the great Bahodium solder and the "Advanced Heat Radiation and Gasification". I'll stick with my so-called "reflow" process.

You are right, RSS profile is not the correct description. I am using a profile which heats up quickly to let the flux spread. Next linear up to activate the flux and prevent thermoshock. My experience is however, that small changes in this profile

and also that most connector/PTH component vendors test their components with immersion temperatures of around 260 degc & they do not preheat the components, so it does not mimic the heat in a typical wave soldering operation

i would say that if you are doing localized heating than you will be okay, A socket is just a socket and cannot be degraded electrically anyway. Russ

Cannot be done, no way to solder the heat pad underneath center. P.S. Rob also spells color wrong!!! must have been a real bad school!! How does the wave master do it? Russ
