  • Patent number: 4513499
    Abstract: The dimensions of the compliant segment of a compliant pin are carefully controlled, so that upon being inserted into a hole in a circuit board the pin fits snug within the hole, but avoids the use of excessive force which could damage the copper sheathing of the hole. Prior to the pin being inserted into the hole, the compliant segment, which comprises a pair of beam members separated by an opening, has a width measured across its widest part that exceeds the maximum acceptable hole diameter by at least 0.005 inch. When inserted into the hole, the beams abut each other and the compliant segment has a width measured across any part thereof which is equal to the minimum acceptable hole diameter within a tolerance of .+-.0.001 inch. This pin is made from a generally flat strip of metal material which is severed to form therein a pair of metal pieces from which the beam members are made.
