Rework stations are used to repair high quality PCBs with SMD components. Defective components and residual solder are removed using hot air. Next, solder paste printing is performed and new components are soldered into place. The repair process starts automatically when the PCB reaches a predefined surface temperature. The automatic start significantly reduces the thermal load on the PCB, as well as the process time. thermoMETER CT series non-contact infrared temperature sensors are used to measure the precise temperature. Due to its compact footprint, this sensor can be fully integrated into the modular system, which ensures even processing independent of the board’s original temperature.
