Patent ID: 7503811

Claim:
A method of manufacturing an interconnect device for a printed circuit board, comprising steps of: forming a protective film pattern on an even surface of a sacrificial substrate for forming an interconnect device including a first contact section having a bar shape for making contact with a second contact terminal in a space transformer, a connecting section having an O-ring shape of which one side is opened and connected to one end of the first contact section in an integrated manner, a support section having an engaging protrusion in a predetermined portion and connected to one end of the connecting section in an integrated manner, and a second contact section having an O-ring shape and connected to one end of the support section in an integrated manner, wherein the O-ring shape of the second contact section is tightened when the second contact section is inserted into a contact hole in a printed circuit board by an interference fit; filling a conductive material into the inside of the protective film pattern, wherein the conductive material in the protective film pattern being located in substantially the same plane as the protective film pattern; and removing the protective film pattern and the sacrificial substrate from the conductive material to finish the interconnect device, wherein the connecting section is placed in a gap between the printed circuit board and the space transformer and the connecting section is compressed or stretched by external force between the printed circuit board and the space transformer.
