Title:
PRODUCTION OF METAL CLAD LAMINATED SHEET
Document Type and Number:
Japanese Patent JPH0890713
Kind Code:
A
Abstract:
PURPOSE: To produce a metal clad laminated sheet having a desired dielectric constant corresponding to the planned circuit of a printed wiring board and contributing to the miniaturization of the printed wiring board and facilitating the production of the circuit.
CONSTITUTION: A metal clad laminated sheet is produced by arranging metal foil on the surface of a laminate formed by stacking a plurality of prepregs having different dielectric constants. In this case, the dielectric constant range of the prepregs is 2-20 and the difference between the dielectric constants of them is 2-10 and the dielectric constant of the substrate layer of the laminated sheet is 5-9.
