This video demonstrates the critical assembly process in data cable production. Factory workers are skillfully assembling components for semi-finished cables on the production line. Operators first insert precision terminals into injection-molded connector housings, then use specialized equipment for seamless riveting and fixation. The next step involves soldering the cables to connectors, where workers use micro soldering pens to precisely connect hair-thin metal wires to contact points. Each stage includes quality checkpoints, with inspectors using magnifiers to examine solder quality and interface alignment. Finally, after insulation testing and electrical verification, a complete data cable comes off the line. The entire process combines the delicacy of manual operation with the precision of mechanical processing, showcasing the craftsmanship of modern manufacturing.
