The carrier tape is used in the placement process in Surface Mount Technology（SMT) for PCB assembly. It is used with the cover tape which carries and stores the metal components in the cavities of the carrier tape, and form a closed package by sealing the cover tape to protect some easy-deformed components, such as EMI shielding Flame does not polluted and damaged by transportation, and meanwhile it reduces manual operations on the SMT assembly line and assure the quality of the final products.
