REFLOW OVEN WITH A ZEOLITE BOX, AND A METHOD FOR RECOVERING GAS WITH SUCH ZEOLITE BOX
The present application provides a reflow oven (100) and a gas recovery method. The reflow oven (100) comprises a reflow oven hearth (101), a separator (105), the separator inlet (110) being connected to the gas outlet (102) of the reflow oven hearth (101) so that the gases in the reflow oven hearth (101) can flow into the separator (105), a zeolite box (107), the zeolite box inlet (112) being connected to the separator outlet (111), and the zeolite box outlet (113) being connected to the gas inlet (103) of the reflow oven hearth (101) so that the gases flowing through the separator (105) can enter the zeolite box (107) and the gases flowing through the zeolite box (107) can flow out of the zeolite box outlet (113), a sensor (106), which is provided in the gas passage between said zeolite box outlet (113) and the gas inlet (103) of the reflow oven hearth (101). The reflow oven (100) in the present application enables the gases flowing through the separator (105) to enter the zeolite box (107). After most of the flux is removed from the gases in the separator (105), the flux is further removed in the zeolite box (107). In addition, polygonal zeolites have certain volumes and are supported in the zeolite box (107) to form clearances, and thus almost no resistance is brought about to the flow of the gases in the zeolite box (107).

COPPER/CERAMIC JOINED BODY AND INSULATED CIRCUIT BOARD
According to the present invention, there is provided a copper/ceramic bonded body including: a copper member made of copper or a copper alloy; and a ceramic member made of silicon-containing ceramics, the copper member and the ceramic member being bonded to each other, in which a maximum indentation hardness in a region is set to be in a range of 70 mgf/μm.sup.2 or more and 150 mgf/μm.sup.2 or less, the region being from 10 μm to 50 μm with reference to a bonded interface between the copper member and the ceramic member toward the copper member side.
Methods and systems for aligning a component
There is provided a method which includes placing a component on a substrate and extending an alignment member through an opening in the substrate. Once the alignment member is extended through the opening, the component is moved to abut against the alignment member to align the component relative to the substrate. After the component is aligned relative to the substrate, the component is secured to the substrate and the alignment member is retracted through the opening.
SEMICONDUCTOR DIE DIPPING STRUCTURE
A die dipping structure includes a plate including a first recessed portion having a first depth and filled with a first flux material. The plate further includes a second recessed portion, isolated from the first recessed portion, with a second depth and filled with a second flux material. The second depth is different from the first depth. The die dipping structure further includes a motor configured to move the plate so as to simultaneously dip a first die and a second die into the flux of the first recessed portion and the flux of the second recessed portion, respectively.
