Abstract

The invention discloses a polycarbonate composition for LDS with good thermal stability. The polycarbonate composition is prepared from the following components in parts by weight: 60-90 parts of polycarbonate, 2-30 parts of an LDS additive, 0.1-5 parts of a heat stabilizer and 0.3-3 parts of an antioxidant, wherein the antioxidant is prepared from a hindered phenolic antioxidant and a phosphite antioxidant, and the heat stabilizer is prepared from a metal compound, layered double-metal hydroxide and an ultraviolet absorbent. According to the polycarbonate composition disclosed by the invention, by virtue of optimization treatment on the content of each component, particularly combination use of the metal compound, the layered double-metal hydroxide and the ultraviolet absorbent and further combination use of the hindered phenolic antioxidant, the phosphite antioxidant and the heat stabilizer, the components take synergistic effect, thermal degradation of the polycarbonate composition for the LDS is greatly inhibited, the mechanical properties and the processability of the polycarbonate composition for the LDS are improved, and meanwhile, the polycarbonate composition for the LDS is capable of resisting precipitation, solvent extraction and salinization without influencing chemical plating in the formation process.

Description

technical field [0001] The invention relates to the technical field of LDS, in particular to a polycarbonate composition for LDS with good thermal stability. Background technique [0002] With the technological progress of modern society and the rapid development of the communication and information industry, manufacturers need to integrate complex components to gradually make the components smaller, which can be achieved through three-dimensional interconnection devices (also known as in-mold interconnection devices , MID) to achieve. Laser-directing-structuring (LDS) is a special innovative technology for manufacturing MIDs. This technology can be used to manufacture printed circuits on three-dimensional MID flexibly and conveniently at a lower cost without using chemical etching. The LDS process uses thermoplastics as raw materials, but the thermoplastics are added with inorganic metal oxides or organic metal mixtures with special crystal structures. After injection mo...
