ABSTRACT:
A pellet accommodating and aligning jig includes an upper portion having an upper surface in which a plurality of pellet accommodating recesses are formed, and a lower portion having a lower surface. A first through-bore extends between the bottom of each of the pellet accommodating recesses and the lower surface. The end of the first through-bore adjacent the bottom of the recesses constitutes a vacuum exhaust inlet and the end adjacent the lower surface constitutes a vacuum exhaust outlet. Pellets placed in the pellet accommodating recesses are attracted toward the bottoms of the recesses when air is evacuated from the vacuum exhaust inlets of the first through-bores towards the vacuum exhaust outlets. The pellet accommodating and aligning jig further includes a micromesh member formed with a plurality of independent second through-bores each having a diameter smaller than that of each first through-bore, and disposed at the bottom of each of the pellet accommodating recesses.
