Abstract

The invention discloses an insulating bonding sheet, comprising an insulating layer, an antistatic layer, copper foil layers and a glass fiber paper impregnated resin bonding sheet, wherein the antistatic layer is arranged below the insulating layer; an anticorrosion layer is arranged below the antistatic layer; a first copper foil layer is arranged below the anticorrosion layer; the glass fiber paper impregnated resin bonding sheet is arranged below the first copper foil layer; and a second copper foil layer is arranged below the glass fiber paper impregnated resin bonding sheet. The insulating bonding sheet provided by the invention overcomes the defects of poor heat conduction effect and incapability of achieving good heat insulation effect in conventional bonding sheets, and achieves the beneficial effects of good insulation effect, simple processing procedures, high precision and stable circuit board operation.

Description

technical field [0001] The invention relates to the technical field of copper clad laminates, in particular to an insulating bonding sheet. Background technique [0002] As one of the basic materials of the electronics industry, copper clad laminates will inevitably increase with the increasing demand for printed circuit boards (PCBs) in different fields. Market participants will benefit from the development dividends. PCBs are the backbone of electronic components. The development of its PCB industry directly reflects the development level of a country's electronics industry to some extent, and the bonding sheet as the basic material of PCB plays an important role. Therefore, continuous improvement of adhesive sheets is an important prerequisite for continuous development. [0003] The existing bonding sheet has poor heat conduction effect, cannot achieve good heat insulation effect, poor insulation effect, cumbersome processing, and is inconvenient for stable operation of...
