Hydrocarbon resin ceramic bonding sheet and batch production process thereof

Abstract

The invention relates to a hydrocarbon resin ceramic bonding sheet and a batch production process thereof. The hydrocarbon resin ceramic bonding sheet comprises the following components: an inorganic filler, a silane coupling agent, hydrocarbon resin, a curing agent and a solvent. The mass production process comprises the following steps: carrying out surface modification treatment on an inorganic filler by using a silane coupling agent; mixing the surface-modified porcelain powder with a curing agent, hydrocarbon resin, a solvent and other materials, and carrying out planetary ball milling; carrying out tape casting on the mixed solution subjected to planetary ball milling to prepare a raw ceramic tape; and semi-curing and demolding the green tape in a vacuum high-temperature oven to prepare the bonding sheet. The problems that an existing ceramic filled hydrocarbon resin type bonding sheet is poor in thickness uniformity, long in production period and not suitable for batch production are solved. The hydrocarbon resin ceramic bonding sheet is widely applied to modern microwave electronic communication fields such as spaceflight electronic equipment, communication, a Beidou system, a wireless local area network and the Internet of Things.

Description

technical field [0001] The invention belongs to the field of electronic components, specifically, to the field of microwave electronic components, and more specifically, to the field of ceramic materials for microwave electronic components. Background technique [0002] With the development of 5G communication, electronic products in the communication field are developing towards high frequency, high speed, high capacity, and high thermal stability, which puts forward higher requirements for the basic boards for preparing multilayer microwave circuit boards. However, at present, glass fiber cloth is mainly used to impregnate hydrocarbon resin, and after drying, prepregs are prepared, and then hydrocarbon resin bonding sheets are prepared by lamination, copper clad foil, hot pressing and sintering, etc., and glass fiber cloth has obvious direction properties, and there are cross nodes in the glass fiber, the multilayer microwave circuit board prepared by using this type of ch...
