The carrier tape is also divided into different widths depending on the size of the 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 tape has also developed in a precise direction. Currently, there is a carrier tape supply of 4 mm width on the market.
In order to protect electronic components from electrostatic damage, some sophisticated electronic components have clear requirements for the antistatic level of the carrier tape. According to the antistatic level, the carrier tape can be divided into three types: conductive type, antistatic type (static dissipative type) and insulated type.
According to the forming characteristics of the pocket:
An embossed carrier tape and a punched carrier tape. The embossed carrier tape refers to the partial stretching of the carrier tape material by the method of embossing or blistering the mold to form a pocket of a concave shape. The carrier tape can be formed into pockets of different sizes according to specific needs to accommodate the loading. The size of the electronic components; stamping carrier tape refers to the punching or semi-transparent pocket formed by die cutting. The thickness of the electronic components that can be held by the carrier tape is limited by the thickness of the carrier tape itself, and generally can only be used for Pack smaller components.
According to the 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. The mainstream in the market is PC (Polycarbonate, polycarbonate) carrier tape, PS (Polystyrene, polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer resin). Belts, in addition to 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.
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. .
According to the molding method of Kunshan carrier belt:
According to the molding method of the pocket, it can be divided into two types of forming methods: batch type (flat type) and continuous type (roller type). Compared to batch type, the continuous forming method generally has better dimensional stability and higher dimensional accuracy. For batch molding, it is more suitable for making large-sized pockets.
