ABSTRACT:
A resilient sheet of material is used between a cavity plate and a mold base in a sytem used to encapsulate items such as semiconductor devices. The resilient sheet of material compensates for any dimensional variations in the cavity plates. In addition, compensation is also made for dimensional variations of the item being encapsulated. In one embodiment, the sheet of resilient material is used to seal cavity openings in the cavity plate. A method for the use of such an arrangement is also provided.
