Production silicon escapement wheel requires extremely high accuracy technology – deep reactive ion etching technique (Deep Reactive Ion Etching, DRIE). First image
Swiss Replica Watches projection vertical escapement wheel diameter 100mm, only 0.5mm thick silicon wafers (silicium wafer), the silicon wafer size generally consists of
Replica Watches one inch (25.4mm) to 11.8 inches (300mm), thickness of 0.5mm . Silicon wafer usually with a diamond saw or diamond rope saw from semiconductor boule (boule) cut wafer, followed by single-sided or
Replica Watches UK double-sided polishing. A 100mm silicon wafer, can make about 250 escapement wheel.First image projection silicon escapement wheel onto the
Cheap Replica Watches wafer, and then remove the exposed enamel layer, leaving the unexposed portions on the wafer, and then the enamel layer without exposure to plasma etching to be the spacer layer, thus completed silicon escapement wheel begins anisotropic etch (isotropic etching) process. When finished, just a little to clean up the gear surface, all finished products are identical, no balance, concentration, polishing. Therefore, silicon wafers for Frederique Constant escapement wheel friction can produce great importance.
