The cover tape is usually made of polyester or polypropylene film as the base layer, and is composite or coated with different functional layers (such as anti-static layer, adhesive layer, etc.). It can be sealed on the surface of the carrier tape under external force or heating, forming a closed space to protect electronic components in the carrier pocket.

The cover tape is usually made of polyester or polypropylene film as the base layer, and is composite or coated with different functional layers (such as anti-static layer, adhesive layer, etc.). It can be sealed on the surface of the carrier tape under external force or heating, forming a closed space to protect electronic components in the carrier pocket. The cover tape is mainly used in the electronic component mounting industry. It is used in conjunction with a carrier belt to store electronic components such as resistors, capacitors, transistors, diodes, etc. in the pocket of the carrier belt. The cover belt is sealed above the pocket formed by the carrier belt to form a closed packaging, used to protect electronic components from contamination and damage during transportation. During the installation of electronic components, the cover strip is peeled off, and the automatic installation device accurately locates the components held in the pocket through the index hole of the carrier strip, and then places them on the integrated circuit board. According to the material of the carrier, it can be divided into PS carrier, ABS carrier, PET carrier, PC carrier, HIPS carrier, PE carrier, etc. The carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with a cover tape (upper seal tape) to carry and store electronic components such as resistors, capacitors, transistors, diodes, etc. in the pocket of the carrier tape. By sealing the cover tape above the carrier tape, a closed packaging is formed to protect electronic components from pollution and damage during transportation. During the installation of electronic components, the cover strip is peeled off, and the automatic installation device accurately locates the components held in the pocket through the index hole of the carrier strip. The components are then sequentially removed and placed on the integrated circuit board (PCB).
