Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Naoi (JP-63-299857A). This is an alternative rejection of claim 6.
With respect to claim 6, Naoi teaches a guide (guide cylinder 20) in the reflow chamber and configured to direct the heat transfer fluid toward a central portion of the substrate (figures 1-2; and machine translation); and a lifter (lifting lowering means 5) configured to lift the stage (figure 3; and machine translation).
At the time of filing the claimed invention it would have been obvious to one of ordinary skill in the art to utilize the guide means of figures 1-2 of Naoi in the embodiment of figure 3 of Naoi in order to direct the vaporized solvent to the desired area of the components being bonded.
Claim(s) 8-15 and 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Naoi (JP-63-299857A) in view of Biedorf et al. (US2003/0168495A1) (hereafter Biedorf).
With respect to claims 8 and 18, Naoi teaches a solder reflow apparatus apparatus (10) (title; figures; and machine translation) comprising: a reflow chamber (10) configured to receive a heat transfer fluid (solvent 2), the heat transfer fluid for transferring heat to a solder for mounting an electronic part (7) on a substrate (6); a heater (heat source 3) configured to heat the heat transfer fluid in the reflow chamber (figures; and machine translation); and a stage (transport belt 12 or lifting/ lowering mean 5) the reflow chamber to support the substrate (figures; and machine translation); and a guide (guide cylinder 20) in the reflow chamber and configured to direct the heat transfer fluid toward a central portion of the substrate (figures; and machine translation).
With respect to claim 8, Naoi does not teach the stage (1) inclined with respect to a bottom surface of the reflow chamber to induce the heat transfer fluid toward a central portion of the substrate
However, Biedorf teaches the stage (1) inclined with respect to a bottom surface of the reflow chamber (14) to induce the heat transfer fluid toward a central portion of the substrate (figures 1-3; and paragraphs 34-41).
At the time of filing the claimed invention it would have been obvious to one of ordinary skill in the art to utilize the inclined stage of Biedorf in the apparatus of Naoi in order to allow bubble to escape from the solder.
With respect to claim 9, Naoi teaches wherein the guide comprises at least one funnel (guide cylinder 20) at a (bottom) side surface of the stage (12), the funnel comprising a body and an outlet (tip opening 21) at an upper end of the body that is directed or oriented toward the central portion of the substrate (figures; and machine translation).
