Hi I am etching PCB(size:6x4 inches) at home by UV light tubes using negative dry film photorsist. Photoresist is used in wafer fabrication to transfer a circuit pattern onto the wafer. During a previous reactive ion etching step, reaction products are deposited on the sidewalls of the patterns etched in the Al film and the photoresist on top of it. It can be used as a substrate or insulation layer of thin-film flexible devices such as organic light emitting diode (OLED) display. Photoresists are used in semiconductor electronics and microelectronics to produce areas of a specific configuration that permit access of an etching agent onto the plate. The next step is to expose the artwork design on the film print to a photoresist film using a UV light source. a material sensitive to light that is used in industrial processes such as the chemical etching of integrated circuits and in engraving 2. Etching is a "subtractive" method used for the production of printed circuit boards: acid is used to remove unwanted copper from a prefabricated laminate. Look it over to be sure it is completely developed. ACT CMIK-SACT® CMIK-S positive photoresist stripper is a proprietary formulation specifically designed for effective positive photoresist stripping and residue removal from highly corrosion-sensitive metals and metal alloy substrates. Etching is the process of removing regions of the underlying material that are no longer protected by photoresist after development. com Cheap paint bell, Buy Quality ink for offset printing directly from China ink china Suppliers: 100g Photoresist Anti-etching Blue Ink Paint for DIY PCB Dry Film Replacement Enjoy Free Shipping Worldwide!
