SMT reflow, short for Surface Mount Technology reflow soldering, is a key process in electronics manufacturing. It’s used to attach surface – mount components to printed circuit boards (PCBs). First, solder paste, a mixture of solder alloy and flux, is printed onto the PCB pads. Then, components are precisely placed on the paste by a pick – and – place machine.
The PCB is then sent through a reflow oven, which has multiple temperature – controlled zones. In the pre – heat zone, the board is gradually heated to around 150 – 180 °C to activate the flux and prevent thermal shock. Next, in the soak zone (180 – 200 °C), the temperature is kept stable, allowing the flux to fully work. In the reflow zone, the temperature peaks at 230 – 250 °C, melting the solder to form strong joints. Finally, in the cooling zone, the board cools down, solidifying the solder joints. This process ensures reliable electrical and mechanical connections between components and PCBs.
