Abstract
The method and apparatus for manufacturing of folded-fin heat sink assemblies provide laser welding of the folded-fin assembly to the base, core or other heat-absorbing mass, at selected locations, prior to brazing or otherwise bonding. This ensures proper positioning of the folded-fin assembly relative to the heat-absorbing mass, and proper spacing between adjacent fins.
