Problems solved by technology

This technology requires the use of special plastic raw materials, which is costly and cannot meet the needs of large electronic product casings and high-end electronic products with high material performance requirements.
Moreover, LDS antennas cannot implement conductive lines on glass and ceramics, which greatly limits the application of high-performance composite materials such as carbon fiber composite materials, glass fiber composite materials, and ceramic materials in LDS antenna technology.
As 5G has higher and higher requirements on radio frequency and substrates, antennas with traditional substrates will also be difficult to meet

Abstract

The invention discloses a high-temperature coating material for forming a weldable metal circuit. The high-temperature coating material comprises the following components in percentage by mass: 50-70%of a high-temperature-resistant resin, 15-20% of laser engraving powder, 0.5-2% of a leveling agent, 0.5-2% of an active diluent and 10-35% of a curing agent. According to the invention, the high-temperature-resistant resin formed by combining an epoxy resin, an organic silicon resin and polyphenylene sulfide has high adhesion to PPS, LCP materials, glass, ceramics, metals and other base materials; the laser engraving powder is added according to a specific ratio, and laser engraving and chemical plating are carried out after different base materials are sprayed and cured to form a conductivemetal circuit, so that the formed circuit can be subjected to high-temperature tin soldering and has outstanding high-temperature resistance; and the prepared antenna is strong in signal receiving capability, and the impedance performance of the conductive circuit is good. The invention further discloses a preparation method of the high-temperature coating material for forming the weldable metalcircuit, wherein the high-temperature-resistant resin components are good in compatibility, the coating material components are uniformly dispersed, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature coating for forming weldable metal circuits and a preparation method thereof. Background technique [0002] In recent years, my country's mobile communications have made unprecedented achievements. The world's largest 4G network has been built, and the 5G network is ready to go. The Internet of Things and smart hardware products need antennas to transmit data through the Internet. Antennas are very important components in wireless communication devices. At present, FPC and LDS antennas are commonly used, but FPC antennas need to be adjusted individually according to each product, which makes assembly difficult, and the base material PI film cannot meet the transmission requirements of 5G millimeter waves. LDS (Laser Direct Structuring) is an evolutionary version of FPC antennas, with extremely high space utilization. It is suitable for situations where there ...
