By implementing statistical process control system in contamination control, organizations can effectively monitor, control, and improve cleanliness levels. SPC provides a data-driven approach to maintain consistent contamination levels within acceptable limits, reducing the risk of product defects, ensuring customer satisfaction, and enhancing overall process efficiency. The PartSens 4.0 enables the implementation of SPC for surface cleanliness. PartSens 4.0 is a state-of-the-art system that uses grazing light detection on TapeLift Pads to measure the number, size, and location of deposited particles on components or in the environment. The data points are gathered at-line and presented at the site of production almost in real time thus facilitating quick reaction.
