Datapaq has launched a tailored version of its SolarPaq temperature profiling system for contact paste drying processes.
A photovoltaic manufacturing line may contain up to three ovens that are used for drying the contact paste. Ensuring that all of these maintain maximum throughput and efficiency requires regular checking of the temperature profile. Incorrect drying will directly reduce process yield and the conversion efficiency of the final product.
The application-tailored data logger is suitable for ovens with clearances as low as 10mm. The DQ1840 logger, a new model from the established Q18 series, withstands two to three minutes at up to 300°C without additional thermal protection. It is housed in a rugged stainless steel enclosure designed to reflect heat energy. Any absorbed energy slowly heats up the high-mass case protecting the electronics. The status indicators and buttons are all recessed to protect them from direct heat and minimise heat entry to the logger circuits. The four-channel data logger stores up to 55,000 readings per channel. It can take up to 20 readings per second, ensuring that even the smallest temperature deviations are captured.
Temperature profiling solution for contact paste drying processes.
The Datapaq Insight software provides the information required to optimize both product quality and production throughput at every stage in the PV manufacturing line. The temperature profiling system can travel through height restricted ovens monitoring cell temperatures at up to four points.
