| titleOfInvention | Manufacture of ceramic base having through hole |
| abstract | PURPOSE: To manufacture a ceramic base having a through hole enabling reduction of an electric resistance to the utmost by a method wherein paste made up of at least one kind of conductive particles selected from specific metal elements, a dispersive solvent for solating them and a dispersing agent selected from an anionic dispersing agent and a nonionic dispersing agent is filled up in a hole opened beforehand for forming the through hole in a green sheet and is baked. n CONSTITUTION: For conductive particles, at least one kind of particles selected from tungsten, molybdenum, tantalum, niobium, etc., are used. As for a dispersive solvent, α-ternineol, butyral, glycol, etc., can be mentioned and these are used solely or as a mixture of two kinds or more of them. As to a dispersing agent, an anionic dispersing agent, e.g. aliphatic amine salt, aromatic amine salt, heterocyclic amine salt, alkylamine, a polyalkylene polyamine derivative or the like, or a nonionic dispersing agent of an ester type, an ester ether type, an ether type, a nitrogen-containing type or the like, is used solely or as a mixture of two kinds or more of these agents. Minute pores of a green sheet 1 are impregnated, in vacuum, with the α-terpineol, for instance and the paste is printed by a roller. Thereafter excessive paste extruded from the rear of the green sheet is removed by scraping and paste 3 is filled up in a through hole 2 of the green sheet 1. After the green sheet 1 thus prepared is dried preliminarily, it is dried by blowing nitrogen thereon and then the surface of the green sheet 1 is removed by a thickness (h) by grinding. n COPYRIGHT: (C)1991,JPO&Japio |
