Description
Technical Field
The invention relates to the technical field of copper-clad plate manufacturing, in particular to a modified epoxy resin composition, a high-Tg low-loss press-fit copper-clad plate and a preparation method thereof.
Background
With the rapid development of electronic products in the direction of light weight, thinness, small size, high density, multiple functions and microelectronic integration technology, the volumes of electronic elements and logic circuits are reduced by times, the working frequency is increased rapidly, the power consumption is increased continuously, and the working environment of components is changed in the direction of high temperature. The requirement on the heat dissipation performance of the PCB substrate is more and more urgent, and if the heat dissipation performance of the substrate is not good, components on the printed circuit board are overheated, so that the reliability of the whole machine is reduced. How to find the best solution for heat dissipation and structural design has become a big problem in the design of current electronic products. The research and development of the metal-based copper-clad plate with high heat conductivity and high performance is undoubtedly the most effective means for solving the problems of heat dissipation and structural design. The core and key technical point of the metal-based copper-clad plate lies in the insulating layer material, and the heat conductivity coefficient of the insulating layer material is improved to meet the heat dissipation requirement of a high-power product.
The metal-based copper-clad plate is a mainstream substrate used by a high-power supply, military electronics and high-frequency microelectronic equipment as a novel substrate, has excellent performances of thermal conductivity which is nearly 10 times or more, high breakdown voltage, bulk and surface resistivity, excellent high temperature resistance and the like compared with an FR-4 and a common copper-clad plate, and meets the development trend and the demand of high-frequency microelectronics.
The halogen-containing organic matter is added into the existing metal-based copper-clad plate insulating layer, so that the combustion resistance of the product can be greatly improved. However, the halogen-containing materials generate a large amount of toxic gases during combustion, damage the environment and threaten human health. Therefore, various halogen-based regulations are continuously issued by various countries and organizations in the world to limit the use of halogen-based products, and the requirement of no halogenation is an inevitable trend of global development. Due to the limitations of all aspects, the metal-based copper-clad plate industry in China is still at a relatively lagged level in the aspects of software and hardware, and the produced products have low reliability, poor stability and uneven performance, and particularly have a plurality of defects in the aspects of heat conductivity, insulativity, bending resistance, thickness uniformity of insulating layers and the like.
Accordingly, the prior art is yet to be improved and developed.
