Connector manufacturing process involves four critical technical stages: stamping, plating, injection molding, and assembly. Each stage requires precise quality control and advanced manufacturing technologies to ensure reliable electronic connector production. Like illustrated in the following picture. Because of the angle, the reflected light does not stay in the fiber core but instead leaks out into the cladding. For a typical board-to-board connector with a 0. 5 mm pitch, dimensional tolerances on. The three primary physical contact types— PC, UPC, and APC —play a decisive role in controlling optical reflections and determining application suitability.
