Abstract
A substrate retention fixture including a base formed of a relatively flat plate with major surfaces and a substrate receiving area formed in one surface thereof with a plurality of openings adjacent the area and in communication therewith. A plurality of spools, one each positioned in each opening, and slideably mounted within the opening for movement between a substrate disengaged and a substrate engaged position. A plurality of springs, one each positioned in each opening, with the spring in each opening engaged with the spool in the opening and biasing the spool into the substrate engaged position. Alignment pins formed to engage and align a substrate positioned in the area, the alignment pins being mounted on one of the base and the plurality of spools.
Claims14
A substrate retention fixture comprising:
- a base having a substrate receiving cavity therein with a plurality of openings adjacent the cavity and in communication therewith;
- a plurality of spools, one each positioned in each opening of the plurality of openings, with each spool being slideably mounted within the opening for movement between a first position in which the spool is disengaged from a substrate positioned in the cavity and a second position in which at least an edge of the spool is frictionally engaged with a substrate positioned in the cavity;
- a plurality of springs, one each positioned in each opening of the plurality of openings, the spring in each opening engaged with the spool in the opening and biasing the spool into the second position;
- and
- an alignment pin mounted on the base within the area for engaging and aligning a substrate received in the area.
