Abstract
A fixture tooling for supporting a back side of a printed circuit board during component placement on a top side of the board includes an inflatable air bladder that is sized substantially coextensive with the circuit board. The bladder is positioned below the circuit board within a containment unit adapted for use with conventional railed assembly equipment. The bladder is selectively inflated for supporting the complete back side of the printed circuit board during assembly operations. The bladder provides evenly distributed support across, substantially, the entire circuit board without damaging any components on the back side by pliably conforming to component irregularities on the back side.
