An electrical connector assembly (1) includes a circuit substrate (3), a dielectric housing (4) and a number of conductive terminals (5) secured thereto seated on the circuit substrate, an integrated circuit package (6) mounted on the housing, a clamping board (7) positioned on the circuit package and a compliant backboard (2) located beneath the circuit substrate, and a number of screws (8) coupling the clamping board and the backboard to each other. The backboard is formed with a number of protrusions (212) abuttingly urging the circuit substrate toward the housing.
