Problems solved by technology

[0006] At present, one type of protective release film is to use silica resin as the main component of the adhesive layer, but this kind of protective release film is prone to the problem of silicone oil precipitation after hot pressing, and it will be difficult to form in the subsequent circuit preparation The problem
The other type is to use Teflon (polytetrafluoroethylene), but Teflon only provides a release function, and Teflon will cause damage to the environment, which is not conducive to the use of green factories
Another type of protective release film is UV-curable protective release film, which is irradiated with ultraviolet light to further polymerize after protective lamination to improve the peeling effect, but the use of this protective release film makes the process more advanced. It is complex, and ultraviolet light is easy to cause damage to laminates or chips during application. In addition, its high-temperature hot-pressing temperature resistance is poor, so there are restrictions on the applicable conditions of the process

Abstract

A hot-press protection release colloid for applying on a surface of an object to be hot-pressed is provided. The hot-press protection release colloid includes an acrylate-based resin, a polymeric isocyanate component, and a solvent, wherein the amount of the polymeric isocyanate component is 1 to 30 parts by weight per 100 parts by weight of the acrylate-based resin, and wherein the hot-press protection has a viscosity of 10,000 to 500,000 cP.

Description

technical field [0001] The present invention relates to a protective release adhesive for hot pressing, in particular to a protective release adhesive for hot pressing using acrylate resin and polymeric isocyanate component (polymeric isocyanate component) in a specific ratio and using the hot pressing A protective release film for hot pressing formed with a protective release adhesive, and their application in a hot pressing process. Background technique [0002] Recently, due to the extensive increase and complexity of electronic products, the contact distance of circuit components has become smaller, the number of connections has become higher, and the length of wiring between points has been locally shortened, so high-density circuit configuration and microvia technology must be used to manufacture related electronic products. Since the wiring and jumper are basically difficult to achieve for single-sided or double-sided, the electronic components are multi-layered. ...
