Abstract:
A method of making a socket test probe for use in a testing device, comprising the steps of:machining from a solid rectangular block of conductive metal a recess on one end of said block of metal which defines a moat around a rectangular tower of metal from the solid block of metal, and which leaves an outer rim of said end; drilling a hole through said block at said tower of metal in said block; using electro discharge machining to expand said drilled hole into a central channel with fluted side channels which define three sides of a number of metal plates, from said tower of metal and through said block of metal; filling said central channel and part of said recess including said moat with a liquid resin; allowing said resin to harden into a solid non-conductive material; connecting electrical connectors to an end of each of said metal plates which protrude into said recess; machining said block of metal in a pattern surrounding said central channel filled with hardened resin, and machining into said moat filled with resin, thereby isolating said metal plates from contact with said metal block from which they originated, and leaving said metal plates encased in resin, with an outside edge exposed to form electrodes, connected to said metal block by said resin in said moat, with an end of said block opposite said side with said recess forming a probe head; and connecting said electrical connectors to a probe interface, for communication with a matching interface of a testing device.
