A fume hood includes a top, bottom sidewalls, front panel and a back panel that define an enclosed workspace. Manufacturing lines for making semiconductor devices generally inspect each fabricated part. The first end having prongs that form a U-shape adapted to cradle a golf club handle. A casing can be disposed on the lead frame covering at least a portion of the lead frame. The bond pads of the lower contact level serve as external bond pads for the package. Thus, slow reproduction is implemented with a high degree of freedom not limited to an integer-fractional speed without requiring a complicated circuit structure.
