Introduction to Reflow Oven Conveyor Speed
The concept of reflow oven conveyor speed is pivotal in the realm of electronics manufacturing, particularly within Surface Mount Technology (SMT) assembly lines. Conveyor speed in reflow ovens regulates the dwell time of printed circuit boards (PCBs) in each heating zone, thereby directly influencing the thermal profile required for proper solder paste reflow and joint formation. This speed is typically measured in centimeters per minute (cm/min) or inches per minute (in/min) and must align precisely with temperature profiles, PCB thermal mass, and component layouts. Such synchronization is essential to ensure uniform heating across the preheating, soaking, reflow, and cooling stages source.
