Abstract

A technique is provided for terminating coaxial cables in a circuit board. Stepped hole 2 is first drilled in circuit board 4 as in drawing, A. Then a plating operation furnishes metal coating 6 with which both surfaces 8 and 10 of board 4 are connected via stepped hole 2, drawing B. The plating in the center 12 of hole 2 is then removed, drawing C, to provide insulation between surfaces 8 and 10. Coaxial cable 16 is then positioned, drawing D, in the double stepped hole and signal line 14 is soldered to surface 10.
