Abstract:
1. A clamping apparatus for applying a force to a workpiece during processing, comprising: a base including opposing support walls defining a work area, the work area configured to receive a joined structure including a substrate and a die positioned over the substrate, a component being positionable in the work area and over the joined structure; and an adjustable releasable structure including a resilient mechanism, the releasable structure configured to be positioned over the component and the joined structure, the resilient mechanism including an inner member being configured to contact the component to apply an inner downward force to the component, and outer members being configured to apply an outer downward force to opposing distal edge areas of the substrate, wherein when an external downward force is applied to the adjustable releasable structure, the inner and outer members apply first and second downward forces to the component and the opposing distal edge areas of the substrate, respectively, during a process of the joined structure, and further comprising: opposing alignment members positioned over the opposing support walls, the opposing alignment members configured to position the component over the joined structure, the opposing alignment members each include a downwardly extending inner flange configured to contact the opposing distal edge areas of the substrate; and the outer members of the resilient mechanism being configured to contact the opposing alignment members, wherein when the external downward force is applied to the adjustable releasable structure, the inner and outer members apply the inner and outer downward forces to the component and the opposing alignment members, respectively, and the external downward force is thereby applied to the opposing distal edge areas of the substrate via the inner flanges during the process, and wherein the inner and outer members are coupled to a plate of the adjustable releasable structure, and the outer members are positionable between the plate and the opposing alignment members, the outer members configured to provide the outer downward force to the inner flanges and thereby the opposing distal edge areas in concert with the force applied to the adjustable releasable structure.
