The Aluminium PCB, also known as Aluminium Clad or Thermally Conductive PCB, is a special type of PCB that consists of thin thermally conductive and electrically insulating dielectric material.
Normally plastic or fiber glass substrate is used in the making of regular PCB, however, in the case of Aluminium PCB, the metal substrate is used; the reason it is also referred as metal base PCB.
Cost-effectiveness and high thermal conductivity are what make these boards stand out from the series of other circuit boards.
