Practical Thermal Profile Expectations in a Dual-Lane, Dual-Speed, Reflow Oven

Dual-lane reflow ovens have been available for years, permitting two boards to be run at the same time in parallel. Until recently, circuit board manufacturers have been limited to processing the same boards or boards with like mass in each of the lanes, but dual-lane reflow ovens with independent lane speeds now make it possible to run boards with larger differences.
