Abstract

PURPOSE:To form partial metal coatings of good quality with good workability and mass productivity by disposing metals of proper shapes on the desired parts of a substrate surface, then heating the metals to melt with a heat source having concentrating characteristic thereby sticking the melt on the substrate surface. CONSTITUTION:For example, a base material 1 of a lead frame for ICs as a substrate is thoroughly defatted, after which gold 2 is disposed on the desired parts to be coated. In disposition, gold powder or foils are temporarily and tentatively stuck to said material by means of paste-like adhesives. The adhesives which evaporate or become harmful in subsequent heating process are selected. Next, laser light 3 is applied concentrically at the power controlled beforehand to the tentatively stuck gold 2. The gold 2 is heated to melt and is thoroughly stuck to the base material 1.
