Abstract: Vertical interconnection technology has the advantages of short interconnection paths and less plane space occupation. It is an important interconnection method for miniaturizing electronic systems. In this paper, we designed an elastic connector structure composed of conductive silicon rubber and metal chassis, the signal transmission between the board and the package circuit is achieved. Through experimental tests, the insertion loss of the elastic connector is better than 2 dB in 0-18 GHz band, better than 5 dB in 18-40 GHz band and the standing wave is less than 2 in 0-40 GHz. The elastic connector basically meets the requirements of RF interconnection.
