Contamination Control for Sensitive Products in the Era of Electrified Vehicles

Abstract

With the growing trend toward electric vehicles, technical cleanliness is also taking on a more prominent role. Insufficient component cleanliness can lead to more frequent or more serious defects, and although contamination con-trol tools and techniques are well known, they are not widely used in production. This article describes how contamination control can be systematically planned and integrated into existing production processes. Contamination control is not a stationary state, but rather a dynamic search for Points of Interest (POI). Only when all POIs have been identified does contamination control become continu-ous monitoring, which ultimately allows the cleanliness requirements specified in the customer-supplier relationship to be verified.
