Abstract

Fig. 1 shows in plan view a portion of a flexible tape cable 1 connected to a printed-circuit board 2. A section taken along line A-A is shown in Fig. 2. The cable 1 carries printed conductors 3 on one side and a conductive ground plane 4 on the other. In the figures the end of the tape cable 1 has been folded back to facilitate the connection of the conductors 3 to corresponding printed-circuit conductors 5 on the board 2.

Flexible Tape Cable Connection

Fig. 1 shows in plan view a portion of a flexible tape cable 1 connected to a printed-circuit board 2. A section taken along line A-A is shown in Fig. 2. The cable 1 carries printed conductors 3 on one side and a conductive ground plane 4 on the other. In the figures the end of the tape cable 1 has been folded back to facilitate the connection of the conductors 3 to corresponding printed-circuit conductors 5 on the board 2.

Prior to making the connections, the cable 1 is located in a desired position with respect to the board 2 by eyelets 6 which pass through preformed holes 7 in the tape cable and plated through-holes in the board. The eyelet 6 has been precoated with solder 8 so that on application of heat a solder connection is effected between the eyelet 6, the ground planes 4 of the tape cable 1 and by the plated through-holes in the board, a central ground plane 9 incorporated in the printed-circuit board 2. No further mechanical working of the eyelet 6 is performed so that the cable 1 may be removed from the board 2 merely by unsoldering. With the tape cable accurately located by the soldered eyelets 6, the remaining solder connection 11 can be made.

Additional strain relief may be provided by a clamp consisting of two elongated members 12 and 13 extending laterally across the cable 1 and board
2. The clamp has been omitted from Fig. 1 for the sake of clarity. Conveniently the clamping screws 14 pass through the holes in the...
