A method for forming a thermal and electrical path in a PCB may include forming a first removable layer over a top surface of a PCB and a second removable layer over a bottom surface of the PCB. The method may also include milling or laser drilling the PCB from the top surface to form a first cavity extending into the PCB, plating the first side panel plating the first side with a second metal to partially fill the first cavity; and milling or laser drilling from the bottom surface to form a second cavity extending into the PCB, the first cavity in a thermal communication and/or an electrical communication with the second cavity. The method may also include panel plating the first side with a second metal to fill the first cavity and the second side with the second metal to fill the second cavity, and removing the first and second removable layers from the PCB to form the PCB with a thermal and/or an electrical path comprising the first cavity and the second cavity filled with the second metal.
