Printed Circuit Line Expose Fixture

      Disclosed is a fixture used for exposing the printed circuit
lines on panels when using diazo or silver halide films (See Fig. 1).

      This fixture is capable of exposing panels which are 19.5" x
22" ranging from 0" - .085" thick.  The thickness variation is
accommodated by using two (2) precision slotted hinges, located on
the back edge of fixture and a collapsible vacuum gasket.

      Two (2) gas cylinders are used for the ease of opening and
closing the top.  The three (3) positioning pins, located on the
fixture base, enter into slotted bushings, located in the top, when
closed, which insures the accurate location of the top to bottom
diazo.
