Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape production, in particular to an electronic carrier tape positioning hole mold. Background Art

[0002] Carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness, and holes (also called pockets) for holding electronic components and positioning holes for indexing are evenly distributed along its length. Carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with a cover tape (upper sealing tape) to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape, and a closed package is formed by sealing the cover tape above the carrier tape to protect the electronic components from contamination and damage during transportation. However, the existing positioning hole mold does not have a waste chip collection mechanism, and the waste chips generated by punching will remain in the mold. When the carrier tape is punched in the next step, these residual waste chips will affect the punching work. At the same time, the spacing between the holes and the positioning holes on the surface of the carrier tape is small, and the instantaneous impact force when the mold is punching is large, so the hole grooves on the surface of the carrier tape are prone to deformation, reducing the quality of the carrier tape after processing.
