PET carrier tape is mainly used in electronic component mounting industry. It is used together with the carrier tape(upper cover tap), carries and stores electronic components such as resistors, capacitors, transistors and diodes in the pocket of the carrier tape, and forms a closed package by sealing the cover belt above the carrier tape, so as to protect electronic components from pollution and damage during transportation. During the mounting of electronic components, the cover tape is stripped, and the automatic mounting equipment takes out the components contained in the pocket in turn through the accurate positioning of the tape index hole, and pastes and installs them on the integrated circuit board (PCB).

By width:

PET carrier tape is divided into different widths according to the size of electronic components carried by the package. Common widths are 8mm, 12mm, 16mm, 24mm, 32mm, 44m, 56mm, etc. With the development of the electronic market, the chip has a smaller and smaller trend, and the carrier belt is also developing in the direction of precision. At present, there is a supply of carrier tape with 4mm width in the market.
