Abstract: A method for soldering at least one substantially large terminal of a high power electrical component to a substantially large area contact surface includes depositing soldering material on the substantially large area contact surface according to a protruding pattern and placing the at least one substantially large terminal on the deposited soldering material. The at least one substantially large terminal, the soldering material and the substantially large area contact surface are heated according to a predetermined heating profile. The protruding pattern defines a plurality of passages leading toward the perimeter of the substantially large contact surface. The area of the at least one terminal substantially overlaps with a portion of the substantially large area contact surface, and the passages provide discharge of gas, entrapped between the soldering material and the at least one substantially large terminal, toward the perimeter, to produce a substantially void free solid soldering material.
