    摘要： An implantable lead having a silicone rubber lead body which has a reduced coefficient of friction on an internal or external surface. The reduction in coefficient of friction is accomplished by extruding a tubular lead body to define a plurality of small parallel longitudinally extending grooves on the inner or outer surface of the lead body. The grooves may be formed by means of a die having inwardly or outwardly directed projections that form the grooves during the extrusion process. The formation of the grooves during extrusion provides a lead body having a lower coefficient of friction without the necessity of additional manufacturing process steps and without additional manufacturing costs.

    摘要： An assembly is disclosed for releasably mounting a semiconductor package with respect to a rigid carrier, in a predetermined alignment with the carrier to protect the package leads and position the leads for electrical testing. Two substantially identical dielectric frames are positioned on opposite sides of the leads and fastened in a sandwich arrangement enclosing remote end portions of the leads. Registration openings, provided at opposed corners of the frames, receive registration pins projected from the carrier, thus to positionally align the package and carrier in transverse directions. Spring-loaded retainers engage a central body of the semiconductor package to retain the package against longitudinal movement relative to the carrier.
