Title: Mounting printed wiring board and manufacture thereof
Inventor: MOTOMURA TOMOHISA
IPC: H05K3/34
Filed: 1994-10-07
Abstract: PURPOSE: To realize a mounting printed wiring board which is high in mounting density and whose wiring is high in both reliability and density by a method wherein its terminal electrically connected to an input/output terminal of an electronic part is finely formed through a printing method or the like on the tips of conductive bumps which penetrate through an insulator layer. CONSTITUTION: A synthetic resin sheet 3 which is 50μm in thickness and serves as a board main body is laminated out a surface of an electrolytic copper foil 1 where conductive bumps 2 are formed. The laminate is set between the hot plates of a hot press kept at a temperature of 180 deg.C, compressed by a pressure of 1.96×10<6> Pa, and left to stand for 15 minutes to obtain a laminated board where the tips of the conductive bumps 2 are exposed protruding from the other surface of the resin sheet 3, penetrating through it. Thereafter, a low-resistance layer 4 is deposited on the exposed tip surfaces of the bumps 2 by successively plating the surfaces with Ni and Au through an electroplating method.  Then, an etching resist is printed on the surface of the electrolytic copper foil 1, a selective etching operation is carried out, and the etching resist is removed by an alkaline water solution.

Title: Stabilization of aqueous solution of divalent iron salt
Inventor: TAKEMURA MASAICHI
IPC: A61P7/06
Filed: 1988-09-30
Abstract: PURPOSE:To stabilize an aqueous solution of a divalent iron salt by adding a polyphosphoric acid or salt thereof as an economical additive harmless to living organisms to the aqueous solution of the divalent iron salt. CONSTITUTION:An aqueous solution of a divalent iron salt is stabilized by adding a polyphosphoric acid or salt thereof to the aqueous solution. The amount of the polyphosphate added is normally 0.1-7mol%, preferably the order of 0.5-3mol% based on the divalent iron salt and excessive addition must be avoided because of blocking free divalent iron ions. In addition an iron (divalent) polyphosphate is preferably used as the polyphosphate as disappearance of the iron salt can be reduced. A porous base material is added to a divalent iron salt suspension containing a prescribed polyphosphate under stirring or a porous base material is added to an aqueous solution of the divalent iron salt followed by addition of a polyphosphate thereto under stirring. From the resultant mixture water is distilled off to obtain a porous base material having and carrying the divalent iron salt adsorbed. The obtained material is suitably used as a feed additive because the material has functions inherent to the divalent iron salt.
