Abstract:
An apparatus configured to temporarily support a Ball Grid Array (BGA) component against a printed circuit board (PCB) during a manufacturing reflow operation, the apparatus including a support plate sized to fit over the BGA and having one or more mounting holes external to the periphery of the Ball Grid Array component, a retaining member for each mounting hole, passing through said mounting hole, a resilient biasing member for each retaining member, wherein the resilient biasing member urges the support plate against the BGA component from below the BGA component such that the BGA component is urged against the PCB.
