Patent ID: 8385082

Claim:
An electrical connection arrangement, comprising: an IC package; a PCB having a plurality of receiving holes for receiving a plurality of contacts therein, each of the contacts having a contacting portion engaged with the IC package that is seated upon the PCB; and a block board engaged with a lower surface of the PCB to support the contacts and prevent the contacts from escaping away from the receiving holes; wherein each of the receiving holes has an inner surface provided with a conductive layer, the contact being electrically contacted with the conductive layer; wherein the contacts include grounding contacts and signal contacts and the PCB is provided with a metal sheet on an upper surface thereof, the conductive layer in the receiving hole for the grounding contact being electrically connected to the metal sheet, while the conductive layer in the receiving hole for the signal contact being insulative from the metal sheet by an insulator; wherein the PCB further comprises a plurality of shielding holes each having a smaller diameter than the receiving hole, the metal sheet extending into the shielding holes so as to provide shielding function and prevent cross-talk between the contacts.
