Abstract

Method for manufacturing a cooling system (100), the method comprising the following steps: • providing a heat sink (101) made of aluminium or an aluminium alloy (300); • coating the heat sink (101) with an insulating layer (102) by anodic oxidation (301); • selectively applying at least one copper layer (103) (302); • applying at least one unpackaged chip (105) to the copper layer (103) (303); • wherein the insulating layer (102) is selectively removed before the at least one copper layer (103) is applied.
