Used to identify and write production process flow, realize product processing technology guidance, whole process quality traceability, etc.
Silicon wafer production process flow - texturing/boron diffusion/alkali polishing/POLY/annealing/ALD/positive film/back film/screen/test sorting
In each flower basket, an RFID tag is implanted, and the RFID reader RF-HZ50L-R4 product is installed with an industrial RFID bus module at the loading and unloading and transfer position of the processing machine in each process step. When the carrier reaches the loading and unloading and transfer position of the machine, the RFID reader reads the unique information of the flower basket RFID tag, and combines with the MES management system to obtain the product information of the silicon wafer in the flower basket, realizing accurate tracking and effective management of the entire production process of the silicon wafer.
