Abstract:
A method for connecting together first and second printed circuit boards, wherein the first printed circuit board has a first plurality of circuit traces arranged on a first surface thereof and terminating proximate a first edge thereof, and wherein the second printed circuit board has a second plurality of circuit traces corresponding to the first plurality of circuit traces and arranged on a second surface thereof, said method comprising the steps of:(a) arranging the first and second printed circuit boards with the first edge of the first printed circuit board overlapping the second printed circuit board, such that the first and second pluralities of circuit traces are matchingly facing each other and are separated from one another by a predetermined spacing K;(b) shielding the first and second printed circuit boards with a non-solder-wettable shield having an aperture therethrough, such that substantially only the first edge and portions of the first and second circuit boards immediately adjacent the first edge are exposed through the aperture; and(c) introducing molten solder through the aperture proximate the first edge of the first printed circuit board, so as to urge capillation of the molten solder between the first and second printed circuit boards.
