Aluminum PCB Applications:
Aluminum back PCBs are perfect for situations where thermal heat dissipation requirements are very high.
PCBs clad with aluminum is more operative at directing thermal energy away from printed circuit board components, therefore, it provides better temperature management for PCB designs. Aluminum-backed designs can be as much as 10 times more effective than fiberglass-backed designs when it comes to removing thermal energy from circuit board components. The much higher thermal dissipation rate allows higher power and higher density designs to be implemented.
Although they were originally designed for high power switching supply applications, aluminum-backed printed circuit boards have gained popularity in LED applications, including traffic lights, automotive lighting, and general lighting. The use of aluminum designs allow the density of LEDs in the PCB structure to be higher and for the mounted LEDs to operate at higher currents while staying within specified temperature tolerances.
The lower operating temperature of the LEDs in design means the LEDs can operate for longer periods of time before they fail.
Aluminum core PCB materials are very operative in thermal heat dissipation applications that include high-power surface mount integrated circuits. Because of the high level of thermal dissipation associated with aluminum-backed PCBs, circuit board designs can be simplified. Aluminum PCBs eliminate heat sinking and forced air, which eventually lowers the design cost. Just about any design that can be made better by improving thermal conduction and temperature control is a candidate for an aluminum-backed PCB.
Aluminum base PCBs consist of aluminum backing whereas traditional PCBs use a fiberglass substrate (FR4 is standard), standard circuit layers and thermally conductive dielectric layers (a thin PCB bonded to the aluminum backing). As a result, the circuit layers can be just as complex as the layers mounted on traditional fiber PCBs.
Aluminum-backed PCBs can dependably increase shelf life and durability of design through associated reductions in failure rates and temperature control.
Aluminum designs also deliver low thermal expansion levels than other PBS designs and better mechanical stability.
