Abstract

The present invention relates to a method of producing high-density polyidimide (HPI) films and its production equipment. The production equipment comprises a raw material supplying means, a vacuum cavity, an energy supplier, a clad laminator, and a baked solidified polymer. The foregoing components constitutes the production equipment, using the monomer with the CONH bond or copolymer as raw materials to extract the unsaturated C═N bond by heat, electrons, light, radiation rays or ions as energy under low-pressure environment, so that the H in vacuum can extract the non-solidified HPI film from the electronic radical covalent polymers and via heat or light to rearrange the structure into a solidified HPI film. By means of the method according to the present invention, the original HPI that is not easily to produce as a film can be easily made in form of a film of HPI polymer on the clad laminator.

Claims

1. A manufacturing equipment for producing a high-density polyimide film, comprising:

a vacuum cavity, used to provide a low pressure reaction environment of 20 torrs or below;

a raw material supplying means to supply raw material containing idimide bond into said vacuum cavity for reaction;

an energy supplier being disposed in said vacuum cavity to provide energy for the decomposition, repeated decomposition, and recombination of said raw material; and

a clad laminator and associated clad laminator tool being disposed in said vacuum cavity, wherein said clad is used for producing said polyidimide film to accumulate on, and said clad laminator tool is used to fix said clad laminator in position.

2. The manufacturing apparatus in claim 1, further comprising an ultraviolet light incident device being disposed in the said vacuum cavity or outside said vacuum cavity for providing energy for solidification of produced said polyidimide.

3. The manufacturing apparatus in claim 1, further comprising a heating device being disposed in said vacuum cavity or outside said vacuum cavity for providing energy for solidification of produced said polyidimide.

4. The manufacturing apparatus in claim 1, further comprising an ultraviolet light incident device and a heating device being disposed in said vacuum cavity or outside said vacuum cavity for providing energy for solidification of produced said polyidimide.
