This case study details the collaboration between a renowned brand of true wireless stereo (TWS) earbuds and Gore to address particle contamination issues during the manufacturing process. Faced with increasing market returns and the risk of reputational damage, the customer engaged in a thorough analysis that identified dust particles as the source of the problem. In response, Gore's engineering team proposed the GORE® MEMS Protective Vents Style 100 as a tailored solution. The development process involved close collaboration with the customer's design team and local support at production sites to ensure seamless integration. The customized vent was developed and ready for mass production within two weeks, leading to significant outcomes such as the elimination of particle contamination, reduced costs associated with market returns, and the maintenance of high-quality standards. This case study illustrates the effective partnership and engineering expertise that contributed to resolving the contamination challenge.
