Abstract
The present invention is a double-side substrate of thermoplastic polyimide and a manufacturing method thereof. The manufacturing steps are as follows: fabricating a polyamic acid is reacted from dipolar aprotic solvents including aromatic diamines and aromatic tetracarboxylic dianhydride. A thermoplastic polyimide is produced from the reaction of dipolar aprotic solvents including aromatic diamines and aromatic tetracarboxylic dianhydride, and cyclization with high temperature through entrainer. The substrate manufacturing step includes once coating the thermoplastic polyimide, the polyamic acid and the thermoplastic polyimide on a copper foil by coextrusion; the pressing step is to press another copper foil placed on outer layer of thermoplastic polyimide of product made from the substrate manufacturing step under high temperature and high pressure to form finished products. Therefore, the present invention can reduce the thickness of the substrate and have advantages of a size stability, a drug tolerance, a heat resistance, a winding resistance and a process simplification.
