| abstract | (57) [Summary] [Structure] 4,4'-diaminobenzanilide and 4, 4'-diaminodiphenyl ether and N-methyl- 2-Pyrrolidone was charged and dissolved by stirring at room temperature while introducing nitrogen. Then, pyromellitic dianhydride was gradually added to the system and stirred at room temperature to synthesize a polyamic acid solution. The obtained polyamic acid solution was uniformly cast-coated on a rolled copper foil 1 using an applicator and dried to form a polyimide precursor layer 2. This substrate was heated in a drying oven to carry out dehydration ring closure to produce a flexible printed circuit board 3. [Effect] The flexible printed circuit board 3 can be easily etched only with an alkaline aqueous solution and has a linear expansion coefficient of the copper foil 1. Since they are close to each other, curling does not occur in the flexible printed circuit board 3 even if they are laminated directly on the metal foil. Therefore, it is possible to reduce costs in terms of process and equipment, and as a result, it is possible to process at low cost. |
