Abstract

The invention provides an insulating substrate and a preparation method and application thereof, and belongs to the field of electronic materials. The insulating substrate is obtained by coating or impregnating a reinforcing material with a resin composition. The resin composition is prepared from the following raw materials in parts by weight: 9000-10000 parts of a cycloolefin compound containingone or two double bonds and at least one bridge ring, and 0.1-10 parts of a ruthenium carbene catalyst. The insulating substrate is prepared by adopting a specific resin composition, and the copper-clad plate is further prepared so that the glass-transition temperature of the copper-clad plate is effectively increased, the dielectric loss can be effectively reduced during use, and the applicationrequirements of high-frequency and high-speed communication are met. Meanwhile, the prepared insulating substrate or copper-clad plate has good flame resistance and dip soldering resistance, is not liable to absorb water, and is more suitable for preparing electronic materials. In addition, the preparation method is safe and environment-friendly. The insulating substrate is prepared from the resin composition, and then the prepared copper-clad plate can be used for high-frequency and high-speed communication, especially 5G communication, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of electronic materials, and in particular relates to an insulating substrate, a preparation method and application thereof. Background technique [0002] In many electronic products, printed circuit boards (PCBs) play the role of circuit interconnection and are an indispensable part of electronic products. Printed circuit boards (PCBs) are manufactured by etching copper clad laminates (CCL, referred to as copper clad laminates) to obtain related circuits. Copper-clad laminate (CCL) refers to a plate-shaped material formed by impregnating the reinforcing material with resin, covered with copper foil on one or both sides, and hot-pressed. It is the basic material for manufacturing printed circuit boards (PCBs). . [0003] In the production of commonly used single-sided or double-sided PCBs, a series of operations (such as etching, electroplating, drilling, etc.) are performed on the copper-clad board to make the requ...
