Could anyone give me a basic profile temperature settings for a conceptronics 7 zone oven and speed? I have the first couple of zones ramped up to get to the soak temperatures. Is this correct or should I start out with low temperatures and graduall

I heard that Minami has pulled out of the Americas. I could be wrong though. Don't know about Europa. Yes, Minami is very Japanese. Didn't see the MK-210 model, only the 280. The MPM semi-automatic models are SPM and UP100. The DEK is model 248.
