In semiconductor wafer processing, using the corrosion resistance of polytetrafluoroethylene material, HF is added into the corrosion tank of polytetrafluoroethylene to react with silicon dioxide to peel the edge. The polytetrafluoroethylene trough is molded and sintered through a mold, without solder joints, so there is no need to worry about the risk of dripping. In semiconductor production, if you need to soak and clean large parts, you need to use large-scale PTFE welding groove. Shanghai changzhuo company can provide the overall service from the external support framework, PTFE tank design, supporting parts selection.
