AL-Core™ Printed Circuits boards are a proprietary product incorporating most of the features of regular FR4 double sided and multilayer boards including Through Hole Plating, with the benefit of an Aluminum Core. The aluminium core introduces a number of unique characteristics to the PCB. The primary functional difference relates to thermal conduction. The aluminium core acts as a thermal conductor which effectively conducts heat away from the dissipating source (normally a silicon junction) to the aluminium core and then distributes the heat evenly across the entire PCB area. Normal convection cooling can then dissipate the heat from the area of the PCB to the air. Alternately, external mounting hardware or heatsinks can be utilised to further conduct the heat to another location. AL-Core™ introduces a number of functional benefits. The first enables devices which would otherwise exceed their rated working temperatures to be utilised without external heat sink devices. The second relates to the fact that the thermal mass of the PCB itself increases the time constant of all temperature variations to which the assembly is subject. For the components and semiconductor junctions, this reduction in temperature variation, reduces the mechanical damage imposed from thermal stress, effectively significantly increasing the reliability (Mean Time Between Failure {MTBF}) of the assembly. The technology to manufacture this product stemmed from the ongoing development of the AL-Back™ product. A new technology was developed to allow Plated Though Holes to be implemented on the PCB, while being able to effectively electrically isolate the Plated Through Hole from the Aluminium core. With the commercialization of this technology, AL-Core™ has emerged as an innovative product which breaks most of the limitations and barriers imposed on designers of conventional aluminium backed PCBs such as AL-Back™.
