Title: Manufacture of laminate
Inventor: IKETANI KUNIO
IPC: B29C43/32
Filed: 1989-11-07
Abstract: PURPOSE:To shorten the producing process such as the cleaning process of a mirror surface- plate, while the appearance defect of a laminate is remarkably reduced by sealing the metallic mirror surface-plate with the sheetlike objects superimposed on its upper and lower surface before the forming under heating and pressurizing is achieved. CONSTITUTION:In a mirror surface-plate 1, the copper foils 2 for circuits are mutually superimposed on its upper and lower surfaces, and the larger size of the copper foil than that of the mirror surface-plate is used. Two copper foils seal its end part 2a so as to cover the mirror surface-plate. The sealed part preferably has weak adhesive strength so that the copper foil may be separated from the mirror surface-plate in next process, and especially the seal is preferably carried out in the clean environment without floating dust. A plurality of prepregs 3 are nipped between the mirror surface plates 1 covered with said foils 2 and are formed under heating and pressurizing. Since the mirror surface-plate is covered with sheetlike object, the contaminant such as resin or the splash of a material does not deposit on the mirror surface plate and does not enter between the mirror surface-plate and the prepreg or the copper foil, whereby the appearance defect of the laminate caused by the deposit of the contaminant or the depression into the surface of the copper foil due to the contaminant is reduced, and the cleaning steps of the mirror surface-plate is decreased, and then the appearance defect due to insufficient cleaning is also removed.
