[0026] Please refer to figure 2 , step 1, providing the insulating plastic 1 , and attaching metal particles 2 on the surface of the insulating plastic 1 . The insulating plastic 1 is common plastic. The metal particle 2 has an active property, that is, it can be used as a media center for electroless plating. The metal particles 2 may be copper particles, palladium particles or other metal particles that can be used as an electroless plating medium. The metal particles 2 can be attached to the surface of the insulating plastic 1 by spraying, smearing or pasting. Of course, the metal particles 2 can also be attached to the surface of the insulating plastic 1 in other ways, such as soaking the insulating plastic 1 in a solution containing the metal particles 2 so that the metal particles 2 cover the surface of the insulating plastic 1. After the surface of the insulating plastic 1 is soaked, the insulating plastic 1 with the metal particles 2 needs to be dried, so that the...

Abstract

The invention discloses a method for forming a metal layer on an insulated plastic surface, which comprises the following steps: 1. attaching metal particles in a selected region on the insulated plastic surface; 2. applying a laser on the selected region so that the selected region of the insulated plastic is molten and can be mixed with the metal particles; and 3. carrying out chemical plating on the selected selection to form a metal layer in the selected selection. Compared with the prior art, the method disclosed by the invention can be used for directly forming the metal layer in the selected selection on the common insulated plastic surface, and does not need to use any purpose-made insulator material containing metal particles, thereby lowering the manufacturing cost.

Description

technical field [0001] The invention relates to a method for forming a metal layer on the surface of insulating plastic. Background technique [0002] In the industry, in the process of making structures such as antennas and circuits, it is often necessary to form metal patterns in local areas on the surface of insulators. [0003] At present, the commonly used method is: select the insulator containing active metal particles to make parts, and then use laser ablation to ablate the surface of the insulator, so as to expose the metal particles in the insulator, and then put the laser-treated parts into electroless copper or In the nickel chemical solution, the metal copper or nickel positive ions and other negative ions are chemically reacted on the surface of the metal particles by using the exposed metal particles as the chemical plating medium, and then precipitate on the surface of the metal particles to form a metal pattern, that is, on the surface of the metal particle...
