More Information
Summary:The invention discloses a manufacturing method of a rigid-flex PCB. The method includes the steps: A, manufacturing a screen print film, the lower oil level area of the screen print film being 1mm smaller than a windowing duct single side; B, performing acid and alkali resistance glue peelable printing, and filling and covering a windowing duct; C, carrying out a baking step, and solidifying acid and alkali resistance peelable glue; and D, performing electroless copper electroplating, and tearing off the acid and alkali resistance peelable glue after electroplating. A screen printing technology is adopted to fill peelable glue in windowing places to replace conventional gluing by hands, so the production efficiency is greatly improved and the labor intensity is reduced. For different dimensions, people can perform printing filling on flexible areas with different shapes without considering whether glue paper matches the flexible areas in shape and dimension. Therefore, the manufacturing method is improved in universality.
