    • A package manufacturing method capable of manufacturing a package easily and efficiently. The package manufacturing method includes a jig disposing step of disposing a covering jig covering an outer peripheral portion on one surface of a first board so as to expose a hole forming region through a jig opening formed on the covering jig; and a filling step of filling a filling material constituting at least a part of penetration electrodes into holes. The filling step includes a metal mask disposing step of disposing a metal mask 84 on the covering jig so as to expose the hole forming region through the jig opening and a mask opening of the metal mask; and a main filling step of applying the filling material on the one surface of the first board so as to fill the filling material into the holes using a squeegee. The filling step is repeated in several rounds, and in the metal mask disposing step of a second or later round of the filling step, a metal mask of which the mask opening has a diameter larger than that used in a previous round of the metal mask disposing step is used.

    • A snowmobile having a lightweight fabricated frame assembly. The frame assembly includes a number of reinforcing elements, some of which comprise heat exchangers for the liquid cooling system of the engine, so as to provide high rigidity and light weight. The engine of the snowmobile is provided with an exhaust system that permits a relatively short effective length, but minimizes pulse-back effects by forming internal expansion chambers around the exhaust branch pipes. The drive for the snowmobile includes a reversing transmission and a brake assembly associated therewith in addition to a main brake assembly for the snowmobile. Furthermore, there is provided a parking brake assembly that is easy to operate and which will provide the operator with a visual and physical warning of its condition so that the operator will not attempt to operate the snowmobile with the parking brake engaged.
