Gerber data for a substrate includes coordinates for physical features on the substrate. The coordinates are relative to a substrate origin point on the substrate. The gerber data allows a user to specify any of the physical features as soldering targets of a soldering apparatus that includes a motor for moving a soldering iron according to coordinates relative to a system origin point of the soldering apparatus. When the substrate is placed on the soldering apparatus, its substrate origin point differs from the system origin point of the soldering apparatus. The user may input coordinates for the substrate origin point, which are used by the soldering apparatus to derive coordinates, usable by soldering apparatus, from coordinates in the gerber data. In this way, it is possible to reduce the workload of the user when programming the soldering apparatus to perform a soldering process.

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).
