摘要： PURPOSE:To provide a multilayered board which is composed substantially of copper foil and a polyimide resin layer and has an excellent chemical resistance, curling resistance, and adhesive property and its manufacturing method and, in addition, to improve the connection reliability and mounting density of the board by making the board easily connectible. CONSTITUTION:After copper circuits 1' and a thermoplastic polyimide resin layer 3 are respectively formed on both surfaces of a low-linear expansion polyimide resin layer 2, a multilayered structure is constructed by utilizing the sticking function of the layer 3. When a through hole is formed through the layers 2 and 3 and continuity is obtained through the hole, the electrical connection reliability of this multilayered board is improved. In addition, when the layers 2 and 3 are formed by respectively applying the precursors of the low-linear expansion plastic resin and thermoplastic polyimide resin, the adhesive properties of the layers 2 and 3 can be improved.

摘要： PURPOSE:To improve the solubility of a polymer itself, to obtain high photosensitivity in forming a fine pattern and to improve dimensional accuracy by introducing a specified functional group into a molecular skeleton of an imide polymer. CONSTITUTION:A positive type photosensitive polyimide compsn. contg. a polyimide having repeating units of the formula and the content of the unit (m) of 20wt.% of the whole. In the formula, Ar1 is a tetravalent arom. hydrocarbon residue; Ar2 is a divalent arom. hydrocarbon residue with an acyloxy group on at least one position of ortho or meta of an arom. ring; Ar3 is a divalent arom. hydrocarbon residue. As said polyimide compsn. contains a polyimide wherein an acyloxy group is introduced into the main chain to improve the solubility in an org. solvent, the acyloxy group is hydrolyzed upon irradiation with light to provide a change in alkali solubility. As the result, the formation of a fine pattern which cannot be achieved by using the conventional positive type photosensitive polyimide becomes possible.

摘要： PURPOSE:To improve heat resistance and resistance to wear by dispersedly containing a specified amount of polyimide powder in a polytetrafluoroethylene resin, and specifying porosity of the resine. CONSTITUTION:Polyimide powder is dispersedly contained in a polytetra- fluoroethylene resin at the amount of 1 to 50wt. percent, and porosity of the resine is determined to be 5 to 55 percent. The polyimide powder acts as a filler material in PTFE, and is typically obtained by converting polyamide acid obtained by the reaction of aromatic tetracarboxylic acid dianhydride on aromatic diamine into imide. When the new material is used as a sheet, damage to mating materials is reduced, and heat resistance and resistance to wear are also improved.
