Suzhou CHIPTUBE Semiconductor Technology Co., Ltd. is a high-tech enterprise that focuses on processing all kinds of parts and inner wall of stainless steel tubes, relying on the unique technology of surface chemical grinding and chemical polishing (CP). Chemical grinding and polishing technology is suitable for the precision machining of high-end semiconductor and ultra-precision medical devices and the improvement of their corrosion resistance ability. The technique of CHIPTUBE has advantages of processing a variety of specially-shaped and complexly-structured parts made by laser-precision cutting art, and it is characterized by the following essences: flat, smooth, and ultra-clean metal surface; completely removed fine burrs; eliminated mechanical stress and enhanced reflective performance; increased corrosion resistance by dozens of times, greatly-reduced magnetism and adsorption, and bacteria free. Some key technical indicators: conforming to SEMI/SGS standard, surface Cr/Fe ratio ≧ 2, Rz ≤ 0.05 μm and up to nm level, suitable for the minimum inner wall diameter of Φ= 0.01mm.
