Photo-etching

The process of spraying chemical solution over the material to remove exposed metal parts. The areas under photoresist left after the exposure and development are the actual product areas. The etching machine used at our company performs the entire process, from spray etching to rinsing and drying. A special etching solution used at our company reduces the side etching and ensures uniformity of the half-etching depth. Please contact us for further information or questions.
