An upper sealing ring and a lower sealing ring are adhered by sealing solder. The width of tip end of sealing projection is narrower than the width of the lower sealing ring. Therefore, the sealing solder is placed on lower sealing ring and on the side surface of upper sealing ring. Further, an upper connection pad and a lower connection pad are adhered by connecting solder. The width of a tip end of a connection projection is narrower than the width of lower connection pad. Therefore, the connecting solder is placed on the lower connection pad and on the side surface of upper connection pad. Thus, a package is provided, which attains satisfactory electrical connection and hermetic seal after solder joint of the upper and lower substrates.

A nozzle ejects molten metal in an ejecting direction. The nozzle has a solder-philic surface in a first region and a solder-repellent surface in a second region. The second region is located forward of the first region in the ejecting direction. Before molten metal is ejected, the peripheral edge of the liquid surface of the molten metal is held at a position located further forward in the ejecting direction than the boundary between the solder-philic surface and the solder-repellent surface. The peripheral edge of the liquid surface is thus held before being ejected so that solder drops can be ejected steadily with a uniform diameter, constant direction, and constant speed.

Punch machine 30 has a plurality of punches 52, 53 and dies 54, 61 for punching a hole out of a sheet, a driving means 35 for reciprocating in a direction intersecting with respect to the punch by the driving force of driving source 33, and cam mechanisms 44, 84, 94, 62, 69 for changing the motion of the driving means into the movement direction of the punch so as to transmit to the punch between the punch and the driving means. A plurality of punches are divided into first group and second group. The cam mechanism provided between each punch of the first group and the driving means moves each punch 52 by the motion operation of the driving means in a first direction, and the cam mechanism provided between each punch of the second group and the driving means moves each punch 53 by the motion operation of the driving means in a second direction. Different pattern of punching is respectively possible by the first and second groups of punches.
