Abstract (en)

[origin: WO2021142066A1] Circuit boards, LED lighting systems and methods of manufacture are described. A circuit board (200) includes a ceramic carrier (202) and a body (212) on the ceramic carrier. The body includes dielectric layers (204) and slots or vias (206) formed completely through a thickness of the dielectric layers. The slots are filled with a metal material. A conductive pad (208) is provided on a surface of each of the slots opposite the ceramic carrier.
