A metal foil coated with flame sprayed ceramic is produced in high productivity by flame spraying a ceramic on a surface of a metal foil, while spraying the rear side of the metal foil to be flame sprayed with water from an array of water nozzles arranged across the metal foil for cooling and providing tension to the metal foil.

Process for producing metal foil coated with flame sprayed ceramic

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.
