Electrical connector

A method for mating an electrical connector to a substrate, the steps comprising:

• providing an electrical connector including,
• an insulative housing with a first surface, a second surface, and a plurality of apertures that pass between the first and second surfaces, at least one aperture including a slot disposed from the first surface to part way towards the second surface and terminating in a ledge,
• a resilient contact floatingly retained within at least one-aperture that includes a first spring arm with a first land surface that projects beyond the first surface, a second spring arm with a second land surface that projects beyond the second surface, a center portion, and a retention member, and
• wherein the retention member is disposed within the slot of the aperture, wherein the retention member may move vertically with respect to the housing such that the contact may move vertically with respect to the housing;
• providing a substrate with a plurality of traces on a first surface;
• providing a biasing plate with a substantially planar surface;
• joining the connector to the substrate such that the second surface of the housing faces the first surface of the substrate, wherein at least one contact is aligned with at least one trace;
• applying the biasing plate towards the first surface of the housing such that the substantially planar surface of the biasing plate faces the second surface of the housing, wherein the biasing plate makes contact with the first spring arm of at least on contact, the biasing plate forcing the contact down relative to the first surface of the housing, wherein the second land surface of the contact will make contact with the trace with which it is aligned;
• soldering at least one second land surface to the trace with which it is in contact;
• and
• removing the biasing plate.
