Kev, I looked up records of various hollis machines with 3 preheat zones. and with progressive preheat temp. of 300 400 and 500 with a speed of 3.5ft/min the topside board temp was 120C before entering the wave. the preheat elements were infrared. W

. In general, here are some guidelines for setting heating element temperatures: If there are through hole (TH) components on the board, and you want to reflow them with SMT components together, you may want to consider increasing the bottom
