Abstract
Abstract A printed circuit board having a plurality of traces and pads printed then. Slots or openings of various geometric shapes are formed in the board to provide flexible mounting members. The pads are mounted on the mounting members. Surface-mounted electrical components have their terminals soldered to the pads. The flexibility of the mounting members permits small movements of the soldered joints in response to thermal expansions, vibrations, etc. to control potentionally damaging stresses.
