Knowles Precision Devices has mastered what the industry has historically deemed a costly challenge. Using proprietary process techniques, edge metal adhesion is maximized by eliminating substrate damage resulting from CO₂ laser machining. Design requirements for perpendicular (90°) edge wraps have become reliable and affordable.
