Electrical connector assembly having hybrid conductive polymer contacts

An electrical system comprising:

• a host circuit board;
• an electrical component having a component circuit board;
• and
• an electrical connector assembly electrically connected between the host circuit board and the component circuit board, the electrical connector assembly comprising:
• a support frame having a frame opening, the frame opening receiving the component circuit board, the support frame positioning the component circuit board within the frame opening;
• a carrier coupled to the support frame, the carrier having an upper surface and a lower surface, the lower surface facing the host circuit board, the upper surface facing the component circuit board, the carrier including a plurality of contact openings therethrough;
• and
• contacts coupled to the carrier and passing through the corresponding contact openings, each contact having a conductive polymer column extending between a upper mating interface and a lower mating interface, the upper mating interface being electrically coupled to the component circuit board, the lower mating interface being electrically coupled to the host circuit board, the conductive polymer column being compressible between the upper mating interface and the lower mating interface, the conductive polymer column including an inner core and an outer shell, the inner core being manufactured from a first material, the outer shell being manufactured from a second material, the second material having a higher electrical conductivity than the first material, the first material having a lower compression set than the second material.
