Problems solved by technology

Its disadvantages are: it needs to develop and make hardware and plastic molds, the production cycle is long, and the cost is high
This process needs to re-add a modified layer on the surface of ordinary plastics. The thickness of the modified layer and the stability of the coating and the ordinary plastic substrate are low. After the modified layer is plated with copper and its protective layer, the copper layer will have low adhesion. And other issues

Abstract

The invention discloses a manufacturing method of a three-dimensional circuit. The method comprises the steps of injection modeling of plastic base materials, laser modification of plastic base material surfaces, first-time chemical plating, surface treatment, second-time chemical plating, surface aftertreatment, and three-dimensional circuit forming. The three-dimensional circuit is obtained through the manufacturing method. By means of the manufacturing method of the three-dimensional circuit, the three-dimensional circuit can be accurately, rapidly and economically formed on a common plastic structural part, and the product cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of circuit production, in particular to a three-dimensional circuit and a production method thereof. Background technique [0002] With the improvement of the integration of electronic equipment, the volume of communication equipment is getting smaller and smaller. It is necessary to reduce the size without significantly affecting the function and efficiency of electronic components. In this context, it is very important to realize the same processing technology as the carrier. important. [0003] The current communication equipment includes call function, wifi function, Bluetooth, GPS, NFC and other functions. All functions that require wireless transmission require the support of antennas. The existing antenna manufacturing processes are as follows: [0004] 1. The antenna is made of FPC and metal sheets. Most of the built-in antennas of mobile phones are composed of metal shrapnel and plastic brackets. This struc...
