Hello. What kind of void are you seeing? You said the part was a BGA, is it being underfilled or is it a solder void?

Chip waves are supposed to be turbulant. You have 2 waves, correct? And you're talking about the first wave the board sees, right? What part is not soldering? SOT-23? Yes you should turn your nitro off when not running the wave.

There is no standard for the spacing of components, nor should there be. We have a difficult time picturing your 0805 at a 45* to the wave and the safe pin, but we'd guess this spacing needs to be 10 thou.

Search the archives here for info. There is lots of posts on this. Short answer is Kapton isn't the best solution. Try aluminum tape or conductive glue if you don't feel comfortable soldering with high temp stuff.

If you're too lazy to search, the quick answer I can give you: ALUMINUM TAPE! Try it. DoE's have proven, that it's the 2nd best method for T/C attachment. The best is obviously hi-temp solder.

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.

Nice! Always love to hear people using the Trieber. Sadly, I had to retire mine in favor of a new Electrovert recently. Good luck with it...

If you're concerned, consider reducing the period used to monitor pot temperature in your process monitoring. Then, if you observe temperatures that ramp out of control more often than you expect, it might confirm the suspicion about damage to your

5 mil is perfect for 0402's. If you are printing SnPb solder use apeture reduction such as home plating the pads. However, if youre using SAC, we've found that printing the entire pad works best due to poor wetting compared to SnPb paste. Chris

Hello, I have a question for electronic manufacturers. I would like to know in which cases a solderability test for component leads should be done? Should it be done for all kind of parts or only for those bought from brokers? Also, how often th
