A method is described which provides an inexpensive method of creating individualized support plates for producing double-sided surface- mounted technology (SMT) panels. The method employs an array of movable magnetic support blocks positioned on an alloy iron plate in a pattern to fit around the locations of components mounted on the bottom side of a panel. To assemble double-sided panels, the assembly tooling or fixture must be able to support a panel with components attached to the bottom surface. The solder paste printing and the component placement steps of the SMT assembly process require support, from the bottom side, to prevent deflection of the printed circuit panel. For single-sided SMT products, providing the bottom side support is simple and straightforward, a flat plate or platen is sufficient to support the panel.
