Abstract

The surface mounting of harcons (high density area array connectors) to a printed circuit board is accomplished by use of a printed circuit card strip which holds the springs in alignment, provides a common ground internal plane, and allows soldering of the spring tails to lands on the board which are connected via plated through holes to harcon springs extending out the back side of the board.

Board Cable to TCM Connection System

The surface mounting of harcons (high density area array connectors) to a printed circuit board is accomplished by use of a printed circuit card strip which holds the springs in alignment, provides a common ground internal plane, and allows soldering of the spring tails to lands on the board which are connected via plated through holes to harcon springs extending out the back side of the board.

Shown in the partial view in Figure 1, cable connector or module pins 1 are plugged into harcon springs 2. The harcon springs 2 are soldered to printed circuit lands 4 on printed circuit card strip 3. Harcon springs 2 soldered on one side of printed circuit strip 3 are connected via plated through holds to ground plane 6. Spring tails 11 are soldered to lands 8 on printed circuit board 7. The lands 8 are connected via printed circuit lines to plated, through vias 9 and 10. Plated through holes 9 connect to internal ground plane 12 in board 7. Plated through holes 10 connect to harcon springs 2 soldered into the plated through holes on the reverse side of board 7.

Illustrated in Figure 2 are connectors assembled to the board showing the top side cable or module inserted in place as well as the bottom side cable or module inserted in place. Insulators 13 are also shown in place around contact springs
2.
