Problems solved by technology

However, polyphenylene ether resins with large molecular weight (>10000g / mol) have problems such as poor solubility, poor compatibility with epoxy resins, and high melt viscosity, resulting in insufficient heat resistance, low adhesion, and Poor dimensional stability and other phenomena seriously affect its reliability
Chinese invention patent application CN201110456600.5 discloses a thermosetting resin composition containing phosphorus-containing low-molecular-weight polyphenylene ether resin, epoxy resin, and cyanate resin. Laminates with low dissipation factor, but their peel strength is low (≤1.0N / mm), which cannot meet the manufacturing process requirements of high-performance electronic substrate materials

The modified epoxy resin is used as the main body, the cyanate ester resin and the polyphenyl ether resin are used as a composite curing agent, so that the humidity resistance of the cyanate ester resin and dielectric property of the system are effectively improved, the unexpected effect is obtained, and the prepreg and laminated board with excellent performance are obtained.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and relates to a thermosetting resin composition, a prepreg and a laminate made by using the composition. Background technique [0002] For a long time, epoxy resin has been widely used in FR-4 laminates due to its comprehensive advantages such as wide source of raw materials, good processability, and low cost. However, with the high-speed and high-frequency increase in information processing and information transmission in recent years, higher requirements have been placed on the dielectric properties of laminates for printed circuits. To put it simply, the laminate material needs to have low dielectric constant and dielectric loss to reduce signal delay, distortion and loss during high-speed transmission, as well as interference between signals. However, the dielectric constant and dielectric loss of ordinary epoxy resin substrate materials (FR-4 copper clad laminates) are relativ...
