How Does a Desktop Convection Reflow Oven Operate for Optimal SMT Results?

A desktop convection reflow oven operates by using heated air to solder surface mount technology (SMT) components to a printed circuit board (PCB). The process begins with loading the PCB onto the oven’s conveyor system. The oven features a series of heating zones, which evenly distribute heat around the board.

During the operation, the oven heats the PCB gradually in a controlled manner. This gradual heating allows the solder paste to reach the appropriate temperature without causing thermal shock to sensitive components. After reaching the designated preheat temperature, the system enters the soak phase. In this phase, the temperature stabilizes to allow the solder paste to activate and remove any moisture.

Following the soak phase, the oven transitions to the reflow stage. In this stage, the temperature rises to a peak level, causing the solder paste to melt and flow. This melting allows the solder to bond with both the PCB pads and the component leads. The oven carefully controls the cooling rate after reflow to ensure proper solidification of the solder.

After cooling, the PCB exits the oven. The connection of SMT components is now complete, providing a strong and reliable solder joint.
