The carrier tape is mainly used in the electronic component installation industry. It is used in combination with the cover tape(upper sealing tape), loads and stores electronic components such as resistors, capacitors, transistors and diodes in the bag of the carrier belt, and forms a closed package by sealing the cover tape above the carrier belt, so as to protect electronic components from pollution and damage during transportation. When installing electronic components, the cover tape is stripped, and the automatic installation device sequentially takes out the components contained in the bag through the indication hole of the carrier tape, and attaches the components to the integrated circuit board (printed circuit board).

Cover tape refers to the belt product applied in the field of electronic packaging, which is used together with carrier belt. The cover belt usually uses polyester or polypropylene film as the base layer, and is compounded or coated with different functional layers (antistatic layer, adhesive layer, etc.), It can be sealed on the surface of the carrier belt under external force or heating to form a closed space and protect the electronic components in the carrier belt bag. Carrier tape refers to a strip product with specific thickness applied in the field of electronic packaging. The holes (also known as bags) for containing electronic components and the positioning holes for index positioning are equidistant along its length direction.

The carrier tape is also divided into different widths according to the size of the electronic components loaded in the package. Common widths are 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, 56mm, etc. With the development of the electronic market, the chip becomes smaller and smaller. Accordingly, the carrier belt is also developing in the direction of precision. At present, there are 4mm wide carrier belts on the market. In order to protect electronic components from electrostatic damage, some precision electronic components have clear requirements for the antistatic level of the carrier belt. According to different antistatic levels, the carrier tape can be divided into three types: conductive type, antistatic type (electrostatic dissipation type) and insulating type.

Embossed carrier tape refers to a concave pocket formed by molding or blister stretching parts of the carrier tape material. The carrier belt can form pockets of different sizes according to specific needs to adapt to the size of the included electronic components. Stamping carrier belt refers to the through or semi through bag formed by die cutting. The thickness of the electronic components that can be accommodated by the carrier tape is limited by the thickness of the carrier tape itself, and the carrier tape can only be used to package smaller components.
