Abstract: An electrical adapter assembly (1) comprises an adapter plate (16), and first and second electrical connectors (12, 14) mounted onto opposite first and second surfaces (165, 166) of the adapter plate. The first and second connectors comprise first and second conductive contact tail portions (1232, 1432), respectively, projecting beyond the second and first surfaces, respectively. A method of encapsulating the electrical adapter assembly comprises the following steps. First, trimming the first and second tail portions for facilitating subsequent formation of smooth soldered dots (21). Second, soldering the first and second tail portions to the adapter plate, forming the smooth soldered dots. Third, placing insulative layers (23, 24) over the soldered dots. Fourth, placing shielding layers (25, 25′, 26, 26′) over the insulative layers. Fifth, soldering edges of the shielding layers to the adapter plate with soldering tin (27).
