◪  Bonded fin heat sinks are made by  aluminum/copper base with individual fins bonded into the grooves. Bonded fin technique is a conventional high power heat sink manufacturing technique. We developed several bonding techniques via our own technical innovations and these include highly conductive thermal epoxy bonding, brazing, and soldering so as to greatly enhance the reliability and stability of cooling and avoid any potential risk. the aluminum/copper bases can be extruded, die cast, or machined. Fins are either punched from coil stock or cut from thin plate stock.

◪  Bonded fin heat sinks improve thermal performance because the fabrication allows for higher fin densities and fin aspect ratios . Also bonded fin have lower tooling costs because we just need open the tooling for the grooved base or  machined the grooved base . Other benefits  are no limit on length of airflow ,wide range of material and fabrication options and so on .

Prepare aluminum/copper base and fins according to the design drawings and create Grooved bases.

The fins and bases are joined together by epoxying, brazing or soldering.

Machining and surface treatment on the base and fins so as to form the bonded fin heat sink
