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 and so on. With the development of the electronic market, chips are becoming smaller and smaller, and the carrier tape is also developing correspondingly in the direction of precision, and so far there is already a 4mm width carrier tape supply 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 tape. According to the different antistatic level, the carrier tape can be divided into three types: conductive type, antistatic type (electrostatic dissipation type) and insulating type.
