Abstract
A composite structure, a resin film, and a method of manufacturing the resin film are provided. The composite structure includes a release carrier and a resin film. The release carrier includes a release substrate and a release resin layer that is formed on the release substrate. The release resin layer covers the release substrate at a coverage rate of between 60% and 100%. The resin film is formed on the release carrier. The resin film is bonded to each of the release substrate and the release resin layer.
Claims10
A composite structure, comprising:
- a release carrier, wherein the release carrier includes:
- a release substrate;
- and
- a release resin layer formed on the release substrate, wherein the release resin layer covers the release substrate at a coverage rate of between 60% and 100%;
- and
- a resin film formed on the release carrier, wherein the resin film is bonded to each of the release substrate and the release resin layer;
- wherein an air permeability of the release carrier is between 0 cfm and 15 cfm.
A method of manufacturing a resin film, comprising following steps;
- (a) providing a release substrate;
- (b) forming a release resin layer on the release substrate to obtain a release carrier, wherein the release resin layer covers the release substrate at a coverage rate of between 60% and 100%, and an air permeability of the release carrier is between 0 cfm and 15 cfm;
- (c) forming a resin film on the release resin layer of the release carrier by a dry process or a wet process to obtain a composite structure, wherein the resin film is bonded to each of the release substrate and the release resin layer;
- and
- (d) peeling off the release carrier from the composite structure to obtain the resin film, wherein the composite structure has a peeling strength from 0.1 kgf/inch to 0.8 kgf/inch.
