    摘要: A tester includes a base (10) including a top wall (12) and a control panel (18), a cover (30) pivotably attached to the base, a pair of master cylinders (40) connecting the base with the cover, a holding fixture including a lower unit (50) and an upper unit (70), and a first testing unit. A plurality of first positioning members (54) is formed on the lower unit for supporting a printed circuit board assembly including a printed circuit board (PCB) (80). A plurality of pressing post (76) depends from the upper unit for pressing the PCB, and a plurality of support posts (127) is formed on the top wall for extension through the lower unit to support the PCB. The control panel controls the master cylinders to open and close the cover, and controls the first testing unit to adjustably insert in ports of the PCB for test.

    摘要: The present invention relates to a valve, and a floating action type servo-valve used for fluid control, including a valve body, a torque motor, a pilot stage and a power stage control mechanism. An upper valve block, an intermediate block and a lower valve block are stacked and fastened by a fastener in the valve body. A torsion-bar spring of the torque motor passes through the center of an armature and is fixed to the valve body with a stand. A pilot stage revolving shaft and a power stage revolving stage are provided in a same central line, with a mating between the pilot stage revolving shaft and the upper valve block and a mating between the power stage revolving shaft and the lower valve block. The servo valve includes a shifting enlargement mechanism constitute by a shifting fork and a shifting lever.

    摘要: Methods of making current tracks for semiconductors are disclosed. The methods involve selectively depositing a hot melt ink resist containing rosin resins and waxes on a silicon dioxide or silicon nitride layer coating a semiconductor followed by etching uncoated portions of the silicon dioxide or silicon nitride layer with an inorganic acid etch to expose the semiconductor and simultaneously inhibit undercutting of the hot melt ink resist. The etched portions may then be metallized to form a plurality of substantially uniform current tracks.
