Claim 5:
6. A method for floatingly positioning a chip, comprising the steps of: (A) providing a chip to a chip socket, a bottom surface of the chip socket being provided with at least one vent hole, the at least one vent hole communicated with an outlet end of an air pressure switching valve, the air pressure switching valve further including a first inlet end communicated with a positive air pressure source; and (B) controlling the air pressure switching valve to allow the at least one vent hole to be communicated with the positive air pressure source, a lower surface of the chip being blown by an air flow from the positive air pressure source through the at least one vent hole, so that the chip is air-floated.
