DRIFT PLATE AND JET DEVICE

摘要

A guide vane has a devised guide configuration for changing a flow direction of molten solder. The guide vane comprises a half-cylindrical plate 11 having a prescribed inner surface shape and a prescribed height, being stood on a prescribed board and changing a flow direction of fluid; and a half-cylindrical plate 12 having a prescribed inner surface shape and a prescribed height, being stood on the board 13 on which the first member 11 is stood and changing the flow direction of the fluid as shown in FIG. 1 . The half-cylindrical plate 11 and the half-cylindrical plate 12 are faced so that an inner surface of the half-cylindrical plate 11 is faced to an edge of the half-cylindrical plate 12 and an inner surface of the half-cylindrical plate 12 is faced to an edge of the half-cylindrical plate 11. This structure allows to jet the molten solder to a target place and uniformize a widthwise distribution of the jetting height of the molten solder.
