Use of carrier tape
:
Carrier tape is mainly used in the electronic component mounting industry. It is used with a cover tape (upper tape) to carry electrical components such as resistors, capacitors, transistors, diodes, etc. in a carrier tape, and to form a closed package by sealing the cover tape over the carrier tape for Protect electronic components from contamination and damage during transportation. When the electronic components are placed, the cover tape is peeled off, and the automatic placement device sequentially takes out the components contained in the pocket through the precise positioning of the tape index holes, and mounts them on the integrated circuit board (PCB board).
Carrier classification:
According to the width: According to the size of the electronic components carried by the package, the carrier tape is also divided into different widths. 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 tape has also been developed in a precise direction. Currently, there is a carrier tape supply of 4 mm width.
Carrier material:
The material of the carrier tape mainly includes two types: plastic (polymer) and paper. The embossed carrier tape is mainly composed of plastic materials. Currently, the mainstream in the market is PC (polycarbonate) carrier tape, PS (polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer resin) carrier tape. There are also a small amount of carrier tape prepared from PET, APET and other materials. The stamping carrier tape is mainly prepared from paper materials or PE composite materials.
Product Characteristics
PC materials are characterized by high mechanical strength, good transparency, good dimensional stability, high glass transition temperature and good heat resistance. The mechanical strength of the PS material is lower than that of the PC material, so sometimes the ABS material is made into a three-layer composite sheet to increase the tensile strength of the carrier tape. The mechanical strength of the PET material is close to that of the PC, but due to the crystalline material, the dimensional stability is poor. .
