Abstract

See full text

A method for manufacturing a PCB with an embedded thermal conductor and a PCB are provided. A sheet of copper-clad ceramic serves as a thermal conductor. A sheet of copper foil having no opening serves as an outer layer of a laminate. A part of the sheet of copper foil covering the thermal conductor is removed after a lamination process, to expose a conductive layer as the outer layer of the thermal conductor. Finally, the outer layer pattern is formed. The sheet of copper foil has no opening before the lamination process, so that the sheet of copper foil has good flatness during the lamination process, thereby avoiding wrinkles. Moreover, the sheet of copper-clad ceramic serves as the thermal conductor, so that a pattern is manufactured on the outer layer of the thermal conductor based on the exposed conductive layer.
