You are cooling too fast, and some flux and paste is worse than others... Can you control your cooling zones? Water Temp (higher)? Or Water Flow (less, effectively less cooling)? Changing water temp is prefferable over flow if you can do it. I h

Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

My Quad IVc's will also do the same thing. Mine are equipped with CyberOptics scanners, not QuadAlign. The Cyberoptics scanners do go bad and once they do, they get very warm to the touch and at the same time, if the Quad is reset, the theta axis wil

I would suggest to respect the natural cooling cycle of your equipment. A reflow Oven is a very critical process equipment and needs to be carefully handled. A regular SMT process environment would maintain its ambiuent temp around 22-26 degC. This i

This would be a very helpful [and cool] thing to do.

If you are using water cooling in yr oven , look for flux condensation on the heat exchanger.
