Abstract
PURPOSE: To reduce smearing of a multi-ply sheet at drilling a hole, to permit it to be preferably plated, and to obtain an excellently reliable multi-ply sheet, by drilling the multi-ply sheet with an organic plates having a glass transition temperature above a specified temperature being applied to both the upper and under surface or the under surface of the multi-ply sheet.
CONSTITUTION: In the production of a printed wiring multi-ply sheet, to the under and upper surfaces or only the under surface of a multi-ply sheet (for example, those obtained as follows: a piece of glass cloth is impregnated with a hardening resin composition containing epoxy compounds, amides, cyanic acid esters and so on, and is dried to obtain a prepreg, to which a copper foil is press molded to produce a substrate lined with copper, or with which a circuit plate is combined to produce a multi-ply sheet) is applied organic plates (for example, a laminate plate and the like obtained by molding a prepreg which has been impregnated with a thermosetting resin-containing varnish and dried) having a glass transition temperature above 150°C, and then is drilled. While the material is drilled, the resin of the applied plate will be prevented from melting to adhere to the hole.
