Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin materials fail to achieve low dielectric dissipation factor, high copper foil peeling strength, and stability in high temperature and high humidity environments, which are critical for advanced laminate applications, particularly in 5G communication technologies.
Innovation Solution
A resin composition comprising 100 parts by weight of vinyl-containing polyphenylene ether resin, 2 to 50 parts by weight of a compound with a specific structure, and 20 to 80 parts by weight of polyolefin resin, such as styrene-butadiene-divinylbenzene terpolymer, which enhances glass transition temperature uniformity, reduces dissipation factor variation, and improves copper foil peeling strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional low dielectric materials are used, then dissipation factor is reduced, but copper foil peeling strength becomes insufficient
Solution Approach 1:
The patent uses a composite resin system combining vinyl-containing polyphenylene ether resin with polyolefin resin (styrene-butadiene-divinylbenzene terpolymer, styrene-butadiene-maleic anhydride terpolymer, or other listed polyolefins). This composite approach allows the material to achieve low dissipation factor from the polyphenylene ether component while the polyolefin component provides enhanced copper foil adhesion through its chemical structure and reactivity, thereby simultaneously satisfying both low dielectric loss and high peeling strength requirements
Solution Approach 2:
The patent specifies precise compositional parameters: 100 parts by weight of vinyl-containing polyphenylene ether resin combined with 20-80 parts by weight of polyolefin resin. This parameter optimization ensures the balance between dielectric properties (from polyphenylene ether) and adhesive properties (from polyolefin), resolving the contradiction between low dissipation factor and high copper foil peeling strength
2Loss of energy
If resin materials are optimized for low dissipation factor, then high frequency performance is improved, but stability in high temperature and humidity environment deteriorates
Solution Approach 1:
The vinyl-containing polyphenylene ether resin provides low dissipation factor for high frequency performance, while the polyolefin resin component (particularly styrene-butadiene-divinylbenzene terpolymer or styrene-butadiene-maleic anhydride terpolymer) contributes thermal stability and environmental resistance. The synergistic combination maintains both dielectric performance and reliability under high temperature and humidity conditions
Solution Approach 2:
The patent controls the composition within specific ranges (20-80 parts by weight of polyolefin resin per 100 parts of vinyl-containing polyphenylene ether resin) to optimize the balance between low dissipation factor and environmental stability, ensuring the material performs reliably in demanding 5G communication environments
3Stability of the object's composition
If glass transition temperature uniformity is improved, then laminate performance consistency is enhanced, but material composition complexity increases
Solution Approach 1:
The patent achieves uniform glass transition temperature (ΔTg ≤10°C) by precisely controlling the composition parameters: 100 parts by weight of vinyl-containing polyphenylene ether resin combined with 20-80 parts by weight of specific polyolefin resin. This parameter optimization ensures homogeneous curing behavior and consistent Tg across the laminate, improving performance uniformity without requiring overly complex material systems
Solution Approach 2:
The vinyl-containing polyphenylene ether resin provides specific functional properties (low dissipation factor, reactive vinyl groups for crosslinking) while the polyolefin resin provides complementary properties (adhesion, flexibility, thermal stability). This functional differentiation within a relatively simple two-component system achieves uniform Tg and consistent laminate performance
