A WBCSP substrate and a stepped protection treatment method for copper pads thereof
The application provides a stepped protection treatment method for a copper pad of a WBCSP substrate and the WBCSP substrate. The treatment method obtains a substrate provided with a copper pad. A solidified solder resist layer with a preset opening is formed on the substrate, so that a preset area of the copper pad is exposed. The preset area comprises a single copper layer and a copper oxide layer attached to the surface of the single copper layer. The substrate on which the solidified solder resist layer is formed is immersed in a benzotriazole aqueous solution. The benzotriazole reacts with the single copper layer to form a benzotriazole-copper complex film on the surface of the single copper layer. The benzotriazole does not react with the copper oxide layer. The substrate on which the benzotriazole-copper complex film is formed is subjected to pickling to remove the copper oxide layer. An alkaline solution is used to perform stripping treatment on the substrate after pickling to remove the benzotriazole-copper complex film. Surface treatment is performed on the substrate after the stripping treatment is completed to form an organic soldering film on the preset area of the copper pad.
