Multilayer electrical circuit structure including partially embedded pins for external connection

摘要

An electrically conductive stripline (16) is formed on a thermally fusible sheet (10), with a portion (16a) of the stripline (16) extending adjacent to an edge (10a) of the sheet (10). A cavity (18) is formed in another thermally fusible sheet (12) having an end (18) at an edge (12a) thereof. The sheets (10,12) are laminated together with their edges (10a,12a) aligned, and the cavity (18) aligned with and facing the edge portion (16a) of the stripline (16). A retaining pin (20) may be temporarily inserted into the cavity (18) to prevent collapse thereof during the lamination step. The laminated sheets (10,12) are heated to thermally fuse them together. An electrically conductive pin (28) is partially inserted into the cavity (18) and ohmically bonded to the stripline (18) to provide an external connection.
