[0018]), and continuing, by the temperature-controlling fluid recovery device (fig. 4, fluid reservoir 202 to house the fluid delivered to and removed from the fluid chamber, par. [0017]), drawing the temperature-controlling liquid from the chip slot. The references are combined for the same reason already applied in the rejection of claim 1. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Zhou in view of Li as applied to claim 1 above, and further in view of Hayashi et al. US 2006/0244472 A1 (hereinafter referred to as Hayashi). Regarding claim 7, Zhou and Li discloses the temperature control system of claim 1, , Zhou discloses wherein the at least one fluid inlet portion (fig. 1A, inflow pathway 122, par. [0032]) includes at least one fluid inlet recess (fig. 3, inlets 322, par. [0042]), and the at least one fluid outlet portion (fig. 1A, outflow pump 128, par. [0036]) includes at least one fluid outlet recess (fig. 3, inlets 324, par. [0042]); bottom surface of the at least one fluid inlet recess is flush with a bottom surface of the chip slot (see fig. 3, par. [0042]); a bottom surface of the at least one fluid outlet recess is lower than the bottom surface of the chip slot in a thickness direction of the test socket (see fig. 2, elm. 204, par. [0039]). Changing the location of at least one fluid inlet from the location shown by Zhou and Li to a location on the bottom surface of the at least one fluid inlet recess is flush with a bottom surface of the chip slot; a bottom surface of the at least one fluid outlet recess is lower than the bottom surface of the chip slot in a thickness direction of the test socket absent any criticality, is only considered to be an obvious modification of the Hayashi device that a person having ordinary skill in the art at the time the invention was made would be able to provide using routine experimentation since the courts have held that there is no invention in shifting the position if the operation of the device would not be thereby modified. See In re Japikse, 86 USPQ 70 (CCPA 1950) and MPEP 2144.04 VI. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Zhou in view of Li as applied to claim 1 above, and further in view of Mamodia et al. US 2017/0176516 A1 (hereinafter referred to as Mamodia). Regarding claim 8, Zhou and Li discloses the temperature control system of claim 1, Zhou discloses further comprising a pressing head (see fig. 3, par. [0041]), which is arranged above the test socket (see fig. 3, elm. 300, par. [0041]. Zhou and Li do not disclose the pressing head including a thermal control unit, wherein when the electronic device is tested, the pressing head approaches the test socket and is pressed against the electronic device, the thermal control unit regulates a temperature of the electronic device to a specific temperature. Mamodia discloses the pressing head (fig. 4, TCU head, par. [0032]), including a thermal control unit (fig. 4, TCU head 324, par. [0032]), wherein when the electronic device (see fig. 4, DUT, par. [0032]), is tested, the pressing head approaches the test socket (see fig. 4, par. [0032]), and is pressed against the electronic device (par. [0032]), the thermal control unit regulates a temperature of the electronic device to a specific temperature (par. [0033). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide integrated circuit test using a thermal test or processing head, as taught in Mamodia in modifying the apparatus of Zhou and Li. The motivation would be to provide different amounts of thermal expansion. (see Mamodia: par. [0014]). Allowable Subject Matter Regarding claim 5, the prior art of record does not teach or support, in combination with the rest of the limitations in the claim, comprising a liquid-gas solenoid valve, the liquid-gas solenoid valve including two inlet ends and an outlet end and being electrically connected to the controller, the temperature-controlling fluid supply device and the purge gas supply device being communicated with the two inlet ends respectively, the outlet end being communicated with the at least one fluid inlet portion of the test socket, wherein when the electronic device is tested, the controller controls the liquid-gas solenoid valve so that the temperature-controlling fluid supply device is communicated with the outlet end; when the test of the electronic device is completed, the controller controls the liquid-gas solenoid valve so that the purge gas supply device is communicated with the outlet end.
