Abstract
A massive bus bar for supplying a determined power voltage to a circuit component mounted on a rigid circuit board having a conductor layer connecting the component to a bus bar connecting pad formed on the surface of the board. Plurality of first notches extend through a main surface of the bus bar from a common longitudinal edge, perpendicularly to the longitudinal axis of the bus bar and throughout the full longitudinal extent of the bus bar, and define a plurality of posts which are secured at their bottom surfaces to the conductive pads on the circuit board surface. The first notches facilitate flexing of the bus bar and reduce stresses otherwise produced due to the rigid connection of the bus bar to the circuit board, while not significantly diminishing the current handling capability of the bus bar. Second and third pluralities of orthogonally extending notches, respectively parallel and perpendicular to the longitudinal axis of the bus bar, are formed in the bottom surfaces of each post, further reducing stresses.
