Abstract
A circuit carrying substrate (108) accommodates circuit components (102) with different coefficients of expansion and contraction from that of the circuit carrying substrate (108). Beneath the components (102) a plurality of slots (104) are formed so as to minimize the effects of the differing coefficients of expansion and contraction.
