6Technical requirements
SJ3118-88
6.1Safety: The packaging box should ensure that the wafers in the box are intact during transportation and can withstand the vibration of the third-level highway.
6.2Sealing: Put the polished wafers in the ultra-clean nitrogen environment, stick the sealing tape, and keep the wafers in the box free from contamination after half a year.
6.3Wafer loading capacity (n): The loading capacity of various specifications of carriers is 25 wafers. 6.4Location pins and positioning holes: The spacing size of the positioning pins and positioning holes of various specifications of carriers should meet the requirements of the drawings to ensure that the wafers of different types of carriers of the same specifications can be transferred to each other. 6.5 Materials: The cutter should be made of plastic with good thermal stability, chemical stability and non-contamination of silicon wafers. Wafer packaging box carriers are generally made of plastic injection molding such as polypropylene and high-impact polystyrene; wafer transfer rack carriers are generally made of plastic injection molding such as propylene; wafer cleaning racks are generally made of plastic injection molding such as soluble tetrafluoroethylene. The materials used should be both antistatic and non-antistatic. All types of carriers should have antistatic properties under specific requirements.
6.6 Transparency: The wafer packaging box carrier can be counted with the naked eye without destroying the seal.
6.7 Easy to use: Wafers of various carriers of the same specification should be able to be transferred to each other without the occurrence of card phenomenon: the upper cover and the base of the packaging box should be properly matched, and it is easy to disassemble and package; various carriers should be easy to clean. 6.8 Appearance: The appearance should be beautiful and generous; it can be stacked in a large packaging box, placed stably, and the surface should be clean and bright. 7 Inspection method
