Oven Shutdown Temperature | 2 May, 2012

Hi,

We power down our reflow oven over the weekend, but before that we let the heating zones cool to approx 100degC. Its something we've always done as we were told to do it when we bought the line. Does anyone else do this, and what would happen if it was powered down from reflow temperatures?

Thanks

We do the same, once you kill the power you lose your air circulation. I'm assuming it's not too good for the oven to have all that heat not moving.

We do this If you shut down without cooling first it could warp the chain

Hi, It's not advised to hard-down the re-flow oven.There are two reasons for that ; extreme thermall difference in temp. will cause chain and drive shafts to warp and T/C's to crack.Let your "cooldown" profile do this safely within 45 mins. to an hour for you.The safe-zone temp. is around 80 -90 degree Fahreneit. Hope this will solve the problem. Best regards, pctech
