Hi, when we change model from reflow temperature profile to temperature profile for glue, we always open oven to cool down. It is good for oven? Thank you for your answer.

Hello, the best way is to set the oven to cooldown. Opening the oven is not very good idea, but is not a big issue I think, only bad air in the production. Try if you can to make production from glue to Pb free if it is possible.

We do the same when it happens, we only warn the people arround to stay away while the oven is open, or delimitate the oven with a caution cord.

Check with your adhesive manufacturer. In a previous life we had one line that was either double sided reflow or wave following reflow. When it was ds reflow, we just shut off the wave. When it was reflow/wave, we kept the reflow oven on with the standard reflow profile. Our adhesive mfg said that the reflow profile would not adversely affect the adhesive cure. In fact it would slightly improve adhesion because of the higher cure temp. If they say no, then put up big warning signs that say "HOT, DO NOT TOUCH".
