Datapaq SelectivePaq uses four thermocouples to take measurements from the electronic assembly as it passes through the preheating and dip-soldering phases. Sample intervals can be adjusted to up to 20 times per second. The detailed temperature profiles enable electronics manufacturers to adjust their operations for optimum efficiency, validate the consistent quality of PCBs to customers, and prove adherence to both solder and component temperature constraints. The profiling system combines a four-channel Datapaq Q18 micro datalogger with micro-miniature thermocouple plugs and a low mass thermal shield. It is suited to monitor the performance of machines that offer restricted space and for use with holding frames. The complementary selective soldering process sensor array facilitates regular and frequent process stability measurements.
