Temperature Measurement on PCBs

Rework stations generally require high-quality PCBs with SMD components. Any residuals from soldering and manufacturing defects are removed by means of hot air. The removal process begins when the optimal temperature of the PCB reaches a certain point, after which the replacement of that component is carried out. The automatic start-up helps in reducing the thermal load on the PCB and optimizes the processing time.

Temperature measurement plays a huge role in this process to accurately identify the starting point of the removal process. Non-contact infrared temperature sensor from Micro-Epsilon thermoMETERCT is integrated into the modular measurement system. It offers uniform processing regardless of the board’s original temperature.
