Abstract: PURPOSE: To provide a substrate contact point stud, having low electric migration characteristics without void, by comprising a first metal layer which, reaction with substrate material for sticking, is so deposited as to fill-up the hole of an insulation layer, a second metal layer of fire-proof metal deposited over it, and a third metal layer of fire-proof metal deposited over it. CONSTITUTION: An insulation body is deposited all over a substrate 1. Then, with the insulation body flattened, each part is selectively removed at a pre-determined position for a substrate surface for contact point to be exposed. Then, a reactive sticking layer 15 is deposited all over the insulation body and a contact point hole 5, and a crystal seed layer 21 is deposited on the sticking layer 15. These both layers are stuck by spattering with the sticking layer 15 being transition metal capable of reducing SiO2 , in addition, the crystal seed layer 21 preferred to be fire-proof metal. Then, fire-proof metal such as tungsten is chemically grown in gaseous atmosphere for completing formation of a contact point stud as a filler layer 17.

Title: Bonding method of ethylene-propylene rubber
Inventor: TAKEDA KAZUTOKI
IPC: B29C65/00
Filed: 1982-11-26
Abstract: PURPOSE:To bond the ethylene-propylene rubber with high reliability by interposing an ethylene ethyl acrylate copolymer between the ethylene-propylene rubber and a material to be bonded and heating and melting the whole. CONSTITUTION:The ethylene ethyl acrylate copolymer (EEA) or adhesives mainly comprising the EEA are interposed between the ethylene-propylene rubber (EP) and the material to be bonded of the EP. The whole is heated and melted at 100-150 deg.C, and said EP and the material to be bonded of the EP are bonded.

Abstract: PURPOSE:To obtain a printed board support which possesses an electrical noise preventing effect making the best of the merit of synthetic resin by a method wherein all the surface or the necessary surface of the printed board support is plated through an electroless plating method.
