Abstract
Ceramic coated laminates for printed circuit boards produced by flame spraying a ceramic powder on a metal plate such as copper foil or a woven fabric prepreg, laminating one or two ceramic coated metal plates and woven fabric prepregs so as to place the ceramic layer between the metal plate and the prepreg, hot-pressing the laminated members, and if necessary peeling off the metal plate(s), are excellent in thermal conductivity and heat resistance.
