Used SCREEN RF3S #9311025 for sale

SCREEN RF3S is a photoresist equipment, which uses light to create an etch-resistant layer over a substrate. It works by exposing a light sensitive polymer to ultraviolet light, which creates a mask on the substrate surface. This mask can either be used for a subtractive process, which removes exposed material to create the desired shape, or for an additive process, which adds exposed material to create the desired shape. RF3S is a solvent-resistant system, which is ideal for high-precision etching applications. The unit is designed to create extremely accurate and uniform coatings which resist heat and chemical treatments which could alter the substrate. The masking polymer is also extremely spin-resistant, so it can withstand extremely high speeds in automated spin-coating applications. The light exposure process begins with the substrate placed in a chemical vat, where a light sensitive chemical bath is applied. A UV-sensitive mask is then laid over the substrate, and exposed to ultraviolet light. The exposed light sensitive chemical reacts with the material in the substrate, creating a mask which coats the surface. After the exposure is complete, the mask is washed off and any portions of the substrate which were not exposed to the light remain untouched. The substrate is then taken to the etching chamber, where a chemical etchant is applied. Depending on the type of etching process being used, either exposed portions of the substrate will be etched away, or unexposed portions will be etched away. The etching process can be controlled to produce extremely accurate, high-precision etchings. SCREEN RF3S is ideal for applications which require accuracy and precision, as it provides uniform, spin-resistant coatings and etchings which resist heat and chemical treatments. The machine is also capable of producing extremely detailed etchings and can be used on a variety of materials, including metals and polymers. With its fast, accurate application, RF3S is ideal for any job requiring precise etchings.
