Description

Technical field [0001] The invention relates to the technical field of engineering plastics, and in particular to a low dielectric constant polyphenylene sulfide resin composition and a preparation method. Background technique [0002] Nano-injection molding technology (NMT) is a technology that injects plastic directly onto the metal surface to achieve perfect bonding with the metal. It can be used to replace traditional bonding methods such as gluing, in-mold cladding, and metal riveting to achieve light, thin, and durable products. For short and small purposes, products manufactured using nanomolding technology have a very broad potential market and have low price advantages and processing costs. [0003] The fifth generation of mobile phone communications, abbreviated as 5G. The planned transmission rate of 5G mobile communications will be as high as 10-50Gbps, which is more than 10 times the transmission rate of 4G mobile communications. The arrival of 5G technology m...
