Interconnection device for a printed circuit board, a method of manufacturing the same, and an interconnection assembly having the same

An interconnect assembly including an interconnect device for a printed circuit board, comprising:

• a printed circuit board including a contact hole in which a conductive film connected to an internal circuitry is formed on its inside wall;
• a first guide film fixed on a bottom surface of the printed circuit board and having a first guide opening to open the contact hole;
• a space transformer having a second contact terminal on a top portion and a bump in the vicinity the second contact terminal;
• a second guide film fixed on the space transformer, supported by the bump, and having a second guide opening to be related with the bump;
• and
• an interconnect device including a second contact section having an O-ring-like shape to be inserted into the contact hole by an interference fit, a support section having an engaging protrusion in a predetermined portion and connected to the second contact section in an integrated manner to be inserted into the inside of the first guide opening, a connecting section having an O-ring-like shape of which one side is opened and connected to the support section in an integrated manner thereby being placed between the first guide film and the second guide film, and a first contact section connected to the connecting section in an integrated manner for making contact with the second contact section through the second guide opening.
