A printed circuit board assembly includes a first printed circuit board having a plurality of electrical traces that is attached to a second printed circuit board having a plurality of electrical traces in a substantially perpendicular fashion. The first printed circuit board has a plurality of male terminal tabs that fit into a plurality of female terminal slots of the second printed circuit board to make a plurality of electrical connections between the electrical traces of the first printed circuit board and the electrical traces of the second printed circuit board. The assembly has at least two mechanical connections between the first printed circuit board and the second printed circuit board comprising connector blades that are substantially perpendicular to the first printed circuit board and to the second printed circuit board. The connector blades may also make electrical connections between electrical traces of the first and second printed circuit boards. A method of making an alternate printed circuit board for the assembly involves punching or drilling the alternate printed circuit board to provide a plurality of female terminals in an elongate slot.
