Main function 1: electronic components used and carried with cover belt. It is used in the SMT plug-in operation of electronic components. The electronic components are stored in the carrier belt packaging and packaged with the carrier belt cover belt to protect the electronic components from pollution and impact. During the plug-in operation of electronic components, the cover belt is pulled off, and the SMT equipment takes out the components in the carrier belt in turn through the accurate positioning of the carrier belt positioning hole, and installs them on the integrated circuit board to form a complete circuit system.

Main function 2: 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 belt can be divided into three types: conductive type, antistatic type and insulating type.

The chip carrier belt provides services for the chip to place the chip correctly in the slot. The carrier belt is not only the support of the chip, but also the connecting lead between the chip and the surrounding circuit. In recent years, with the development of large-size and high-definition LCD panels, the market demand for very thin circuit chip carrier has continued to grow rapidly.
