The RF 300 / RF 500 Inline SMT Reflow soldering system heating profile are superior to batch and other ovens for several reasons. Each heating zone is programmable through the controller, which stores up to 100 profiles. The oven includes a real-time temperature profiler port. When a thermocouple is attached to the PC board, the actual Reflow temperature profile is displayed graphically as the board travels through the oven.
