FASTHERM is a new technology developed by AISMALIBAR to achieve a faster thermal transition from the LED thermal pad into the heat sink. This superior thermal transition can be achieved by using the entire COBRITHERM HTC product range with either a copper or copper / aluminum base. AISMALIBAR has created a special laminate with a bimetal heat sink made with a thin layer of copper cladded onto an aluminum base. The aluminum layer possesses diffusive properties while the copper layer has a very thin dielectric for improving horizontal thermal dissipation. The bimetal also allows for solderability in surface mounting applications.
