NOVELTY - Soldering at least one large terminal of a high power electrical component to a large area contact surface (144, 146), comprises depositing soldering material (142) on large area contact surface according to a protruding pattern defining passages (148); placing large terminal on deposited soldering material, and heating the large terminal, the soldering material and the large area contact surface, where passages provide discharge of gas entrapped between soldering material and large terminal to produce void free solid soldering material.    USE - For soldering at least one large terminal of a high power electrical component (e.g. photovoltaic cell, active antenna, or microwave monolithic integrated circuit) to a large area contact surface.    ADVANTAGE - The method enables high power electrical component to operate at a high efficiency and produce a larger electrical power.    DETAILED DESCRIPTION - Soldering at least one large terminal of a high power electrical component (i.e. photovoltaic cell) to a large area contact surface (144, 146), comprises:    (A) depositing soldering material (142) on the large area contact surface according to a protruding pattern defining passages (148) leading toward the perimeter of large contact surface;    (B) placing the large terminal on the deposited soldering material, the area of the terminal overlapping with a portion of the large area contact surface; and    (C) heating the large terminal, the soldering material and the large area contact surface, according to a predetermined heating profile, the passages providing discharge of gas entrapped between the soldering material and the large terminal, toward the perimeter, to produce a void free solid soldering material.    The protruding pattern is determined according to a solder paste stencil placed on the large area contact surface with injectors. An INDEPENDENT CLAIM is included for a high power high thermally conductive platform comprising a substrate.
