What is a Reflow device?

A reflow oven is a piece of equipment used primarily in the manufacturing process of electronic devices, especially in Surface Mount Technology (SMT). Reflow soldering is a process where solder paste is applied to the printed circuit board (PCB) and used to solder components onto the board. The reflow oven provides the heating process necessary for soldering.

Typically, a reflow oven consists of three main zones: the heating zone, the holding zone, and the cooling zone. In the heating zone, the PCB and components are heated to a high temperature, causing the solder paste to melt and bond the components to the PCB. In the holding zone, the temperature is maintained for a set amount of time to allow the solder to stabilize. Finally, in the cooling zone, the temperature is lowered quickly to solidify the solder joints. This process results in high-quality and reliable soldering.

Reflow ovens are crucial for producing high-density and miniaturized electronic devices, requiring precise temperature control to ensure high-quality solder joints.

Application of Reflow device

Here are some specific examples of reflow oven applications:
１．Smartphone PCB Assembly: Smartphones have numerous surface-mount components on their PCBs, and reflow ovens are used to solder these components. To handle high-density component placement, reflow ovens provide precise temperature control to achieve reliable solder joints.
２．Television Circuit Board Manufacturing: Reflow ovens are also used in the production of circuit boards for LCD and LED TVs. As the components used in these devices become smaller, precise soldering is required. The reflow oven ensures accurate component placement and high-quality solder connections.
３．Automotive Electronics Manufacturing: Reflow ovens are used in the production of automotive electronics such as Electronic Control Units (ECUs). These components need solder joints that can withstand high temperatures and vibrations, so the reflow oven performs soldering with high-quality standards to meet these demanding conditions.
