In a method of manufacturing a thermal module consisting radiating fins and heat pipes made of two different metal materials, the radiating fins are subjected to physical vapor deposition to form localized deposited coating, and the heat pipes are applied at areas to be welded to the radiating fins with a welding flux; the welding flux is then heated to its melting point, so as to weld the heat pipes to the radiating fins to form the thermal module. With the localized deposited coating on the radiating fins, heat pipes and radiating fins made of different metal materials can be firmly welded at the coated areas to ensure good welding joints and heat conducting efficiency of the completed thermal module.
