Title:
RESIN MATERIAL AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2018/139645
Kind Code:
A1
Abstract:
A resin material is provided which can effectively improve insulation properties and long-term reliability, can effectively suppress variation in dielectric breakdown strength and can further effectively increase adhesion. This resin material contains first boron nitride aggregate particles, second boron nitride aggregate particles, and a binder resin. The porosity of the first boron nitride aggregate particles is less than 30% and the porosity of the second boron nitride aggregate particles is greater than or equal to 30%. Both the aspect ratio of the primary particles constituting the first boron nitride aggregate particles and the aspect ratio of the primary particles constituting the second inorganic particles are less than 7.
