Abstract
A method for forming a support fixture for a PC card having components on side 1 of the PC card. A compliant porous member is placed on a vacuum platen. Side 2 of the PC card is placed on the compliant member. A membrane is placed over the PC card and the compliant member. Subsequently, a vacuum is drawn to cause the membrane to conform to the geometry of the components of side 1 of the PC card. A perimeter is formed around the PC card to define a mold. Casting material is poured into the mold to conform to the surface geometry of the components on the PC card. The casting material forms a nest which is a mirror image of the components on side 1 of the PC card.
