Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat
There are many names for these products; Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing and perform the same way.
Benefits of Aluminum PCBs
- Heat dissipation is dramatically superior to standard FR-4 constructions.
- The dielectrics used are typically 5 to 10 times as thermally conductive as conventional Cheap Omega Replica epoxy-glass and a tenth of the thickness
- Thermal transfer exponentially more efficient than a conventional rigid PCB.
- Lower copper weights than suggested by the IPC heat-rise charts can be used.
