Abstract
A head assembly for a burn-in board loader and unloader comprises a mounting block having a generally vertical track. A main body is mounted on the mounting block and afforded vertical movement along the track. The main body has a vertical bore through which a vertically movable plunger extends. The main body also comprises at least three vertical mounting wire holes spaced-apart around the bore. A floating crown having a vertical bore through which the plunger extends is mounted on the upper end of the main body by mounting wires which are fixedly attached at their upper ends to the crown and extend downwardly into the mounting wire holes. The mounting wires are fixedly attached at their lower ends to the main body at the lower ends of the mounting wire holes. The crown is preferably mounted to provide a gap between the crown and main body of about 0.005 inch.
