Description

Technical Field

[0001] The present invention belongs to the technical field of chip sorting, and more specifically, relates to a loading and unloading device for a chip sorting machine and a chip sorting system. Background Art

[0002] With the rapid development of semiconductor technology, especially the miniaturization, high integration and continuous improvement of integrated circuit (IC) performance, the requirements for chip testing and sorting are becoming higher and higher. The continuous market demand for high-performance electronic products has prompted manufacturers to seek more efficient methods to increase production and ensure product quality.

[0003] With the rapid development of the electronic products market and the increasing requirements of consumers for product performance, the semiconductor industry is facing huge market demand pressure. In order to meet market needs, manufacturers must continuously improve their production capacity. The use of fully automated loading and unloading equipment can greatly improve the work efficiency of the production line and reduce delays caused by manual operation.

[0004] At present, the loading and unloading of chip sorting machines are all operated manually. The functional (FT) test of chips is carried out in batches of 90k, 300 pic / tray, a total of 300 trays, FT yield of more than 95%, and 60 pick-up and drop operations. The operator takes the product to be tested from the material cart each time, then disassembles the tray with the packing tape, and manually places the material to be tested on the loading station of the chip sorting machine. After sorting by the chip sorting machine, the good materials enter the tray for unloading. When the tray is full, the equipment alarms and the operator takes down the good materials, packs the tray, and finally places the packed materials on the material cart.

[0005] This kind of chip sorting machine loading and unloading method requires manual operation by operators, which is labor-intensive. At the same time, the operators operate frequently, so a suitable man-machine ratio needs to be set. Operators are easily exposed to materials during manual operation, and there is a possibility of electrostatic protection (ESD) failure. In addition, since operators operate multiple devices, they need to continuously pick up and place the materials to be tested and good materials. If the picking and placing are not timely, the equipment will enter the standby state, affecting the equipment's production capacity. Since the material cart can be pushed at will, the material cart needs to be managed and visually identified by on-site personnel. If the position changes or moves, there is a risk of loading the wrong material. In addition, the application of workshop handling robots (AGVs) is becoming more and more popular, and the linkage and docking of chip sorters and AGVs is also very necessary, which is necessary to lay a solid foundation for the realization of fully automatic testing industry or dark light production.
