Thermally insulated printed circuit board

A printed circuit board (PCB) comprising:

• a first side and a second side;
• a conductive layer within the PCB between the first side and the second side;
• one or more first side electrical components that are physically attached to the first side and electrically connected to the conductive layer;
• one or more second side electrical components attached to the second side of the PCB and electrically connected to the conductive layer;
• and
• a thermally and electrically insulating dielectric layer, within the PCB between the first side electrical components and the second side electrical components, that prevents heat emitted by the first side electrical components from increasing the temperature of the second side electrical components, wherein at least one of the first side electrical components vertically overlaps at least one of the second side electrical components.
