ABSTRACT:
An apparatus for stiffening a circuit board during soldering, assembly, and repair/rework, which includes an elongated crossmember having two opposing ends, an outer support leg extending downward from each crossmember end to form a bridge support with the crossmember and a central support leg extending downward from a central portion of the crossmember. A central portion of the circuit board is attached to the central support member to prevent the circuit board from softening and sagging when exposed to the heat from soldering.
