A method for partial plating on the surface of plastic products

Abstract

The invention discloses a partial plating method on the surface of a plastic product, comprising the following steps: S1, metallizing the plastic surface: metallizing the surface of the pretreated plastic product, so that the entire surface is plated with a first metal conductive layer; S2, laser engraving Partitioning: use laser to engrave the outline of the area to be plated on the surface of the plastic product, and expose the substrate of the plastic product at the outline, so that the area to be plated and the non-plated area are partitioned and electrically isolated; S3, the area to be plated is plated with a conductive layer and separated Dissolving the conductive layer in the non-plating area: Connect the electrode to the area to be plated on the surface of the plastic product and energize it. The second metal conductive layer is plated on the area to be plated, and the first metal conductive layer in the non-plated area is dissolved in the plating solution. The invention partitions and electrically isolates the surface metallized plastic products by laser engraving, and dissolves the metal layer in the non-plating area while plating the metal layer on the area to be plated, so as to realize partial plating on the surface of the plastic product, which not only meets the needs of precise and complex circuits It can also improve the quality and efficiency of partial plating and reduce the cost of partial plating.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of plastic products, in particular to a partial plating method on the surface of plastic products. Background technique [0002] In the field of communication electronics, some important parts need to be molded with high dielectric constant materials. In order to make the product have special radio frequency performance, it is necessary to plate functional circuits on the surface of the product, such as: plastic parts formed by LCP materials, usually , the methods of partial plating on the surface of the plastic part are as follows: [0003] (1) Cover the non-electroplating area by spraying anti-plating paint, etc., such as the Chinese invention patent, a method for laser engraving and electroplating on plastic surfaces, the application number is 02127135.6, and the patent discloses the following steps: coating the back of the plastic material Covered with light-transmitting anti-platin...
