When our all aluminum high performance heatsinks cannot meet the operational performance required and liquid cooling is not an option, it is time to try our mixed metal solution. Weight is a cost driver and a heatsink design that incorporates an aluminum baseplate & copper fins or mixed copper and aluminum fins, provides the highest performance at the lowest cost.
Our unique Fabfin swaging process proven over many years to eliminate the baseplate/fin interface barrier is ideally suited to the mixed metal design. Through modeling, experimentation and application knowledge we have overcome the issues relating to coefficient of expansion & electrolysis, allowing us to optimize mixed metal performance.
The images shown here represent a number of unique thermal solutions. Your requirements can be modeled and unique solutions found using the mixed metal option.
