This may sound silly to ask, but does your oven have a center board support by chance? If so is it down when running the boards through the oven? I only ask this because we had the solenoid that operates that function (raise and lower) of the board

We run double sided surface mount boards through our Heller oven without any parts falling off the bottom side unless they are too big/heavy. The trick we use is to set the bottom side temperature in the final 3 heat zones 10C-20C lower than the top

Good afternoon, Oops. Quite huge difference I must say. But you should try to tweak your profile anyway. First of all try to enlarge soak time as Mr. RDR has said. What process type do you use? Lead or lead-free? By the way, there are lead-free proc
