There's a fair amount of material on cooling rates for lead free on the web. Look here: * http://www.speedlinetech.com/docs/Cooling-Slopes-Lead-Free-Reflow.pdf * http://www.findarticles.com/p/articles/mi_qa3776/is_200412/ai_n9473486 * http://www.m

Check out http://www.solderstar.co.uk/wavePro.html This tool measures all key wave solder information with a single pass. Wave/PCB contact, immersion depths, etc. Also has a reflow pack to allow use on reflow, 9 channels with predictive software. B

Steve, KIC does. The new KIC2000 has built in dwell time sensors. You can buy KIC's wavesurfer option (like MOLE's waverider), or you can engineer a custom pallet for 1/3 the price. I made a custom pallet and took advantage of the KIC's automatic

HI All, Please kindly advice me, I have project that it has DPAK part (MPN:SUD25N15-52 E3 Plating:100% Sn matte)which locate on bottom side (1st reflow), Good wetting for 1st reflow.. but .. when I run Top side (2nd reflow).I found that this D

I have seen this before. Check: --Vibration of belt --Interference (part getting "brushed off" while reflowing bottom-side components --Some glues' cross-linking mechanism is impaired by the flux during migration in reflow, redering the glue useless

We have a Nitrogen Silo. Your going to want to be careful if you decide to use nitrogen, not only are the levels unstable most of the time but it can also cause your components to tombstone like crazy, especially if you run a lot of LED's. We run 24/

Peter: Please explain: * You say, "The cooling phase is important to perform the strength of the solder joint." [We agree that fast cooling rates produce fine grain in solder and that fine grained solder connections are stronger than coarse grained.
