Description

technical field [0001] The invention relates to the technical field of semiconductor packaging production, in particular to a conveying system used in a semiconductor packaging production line. Background technique [0002] Semiconductor packaging refers to the process of processing the tested wafers according to the product model and functional requirements to obtain independent chips. The packaging process is: the wafer from the wafer front-end process is cut into small chips after the dicing process, and then the cut chips are glued to the small island of the corresponding substrate (lead frame) frame, and then Use ultra-fine metal (gold-tin-copper-aluminum) wires or conductive resin to connect the bonding pads of the chip to the corresponding pins of the substrate to form the required circuit; then the independent chip is packaged and protected with a plastic case, After plastic sealing, a series of operations need to be carried out. After the packaging is completed, th...

Problems solved by technology

[0003] However, when the conveying system used in today's semiconductor packaging production line transports semiconductors, the conveying and slicing of semiconductor tapes are separate use of corresponding equipment, and there is no clever use of the drive of the conveying system to cooperate with slicing. The structure is complicated. Corresponding use of electrical equipment is required, and the cost of use is high. In order to match the efficiency of conveying and slicing, the programming of the control unit is also required, which increases the troublesome operation. Moreover, the stability of the semiconductor tape during the conveying process is poor, and it is easy to sideways, resulting in uneven slicing. , affects the use effect, and the equipment needs to be re-used for even placement before packaging in the final delivery, which further increases the difficulty and trouble of operation
