POLYCHEM Etcher and Etching Processes:
(1). Screen Printing a negative image of Polychem Etcher on the Predetermined Non-Conductive Areas of the conductive polymer coated films.
(2). Heating the printed conductive films at 110~130C for 5 minutes to allow the Etcher to react with the covered conductive polymer to form Non-Conductive Areas.
(3). Use pure water to flush away the residual Etcher on the conductive polymer coated films. Then, air dries the patterned conductive films to eliminate the residual water on the patterned
films. Then conductive circuits are formed.
