    摘要: A photosensitive polyimide composition; the composition comprises a base agent and a curing agent comprising a photoinitiator. By applying an aliphatic diamine monomer, which has a long carbon chain, and a grafting monomer, which has a main carbon chain having a double bond and an epoxy group at two ends respectively, to a method of making the base agent, a mixture of the base agent and the curing agent can be screen printed to form a photosensitive polyimide film on a copper foil. Also, the photosensitive polyimide film can be exposed under low exposure energy, and can be developed to a solder-resistant polyimide thin film by a weak alkaline developer after exposed. In addition, the solder-resistant polyimide thin film has low dielectric constant, low dielectric loss, good flame resistance, good solder resistance, and good pencil hardness. Accordingly, the photosensitive polyimide composition is applicable to high density flexible printed circuit boards.

    摘要: A polyimide metal laminated plate has a first metallic film, a first thermoplastic polyimide film laminated on a surface of the first metallic film, a first thermosetting polyimide film laminated on a surface of the first thermoplastic polyimide film distal from the first metallic film, and a second thermoplastic polyimide film laminated on a surface of the first thermosetting polyimide film distal from the first thermoplastic polyimide film. The polyimide metal laminated plate has no adhesive layer, so the polyimide metal laminated plate not only has good heat resistance, flame resistance, anti-chemical properties, and dimensional stability, but also meets the thinning tendency of FPCB. In addition, by the first thermosetting polyimide film and the second thermoplastic polyimide film having a water vapor transmission rate equal to or more than 170 g-μm/m2-day, the delamination and whitening of the polyimide metal laminated plate is prevented.

    摘要: A method of making a thermally curable solder-resistant ink, which comprises the following steps: polymerizing an aliphatic diamine monomer having a long carbon chain, an aromatic dianhydride monomer, an aromatic diamine monomer having a carboxylic group, and an anhydride monomer having a carboxylic group in an aprotic solvent to obtain a polyamine acid; cyclizing the polyamine acid to obtain a modified polyimide; and mixing the modified polyimide and a curing agent to obtain the thermally curable solder-resistant ink. By the steps mentioned above, the thermally curable solder-resistant ink made from the method has a dielectric constant less than 3.00 and a dielectric loss less than 0.01 and thereby is applicable to high frequency electronic equipments. Also, the thermally curable solder-resistant ink has good electrical properties, folding endurance, solder resistance, warpage resistance, flame resistance, acid endurance, alkali endurance, good solvent resistance and low water absorption.
