T962A SMD REFLOW OVEN FIX/HACK Replace stinky masking tape
Then there was the source of the problem - masking tape! Masking tape is used to prevent electrical shorts between the aluminum foil used to cover the insulation material and the controller PCBs. Even though there's heat insulation material beneath it, the tape gets hot enough to produce that nasty odor. So I removed all of the masking tape, and replaced it with Kapton tape, which is heat resistant.
