An improved stiffener for printed circuit boards (PCBs) used in semiconductor devices utilizes replaceable connector guide/retaining clips. The newly designed stiffener is glued to the front of the PCB leaving easy access to both sides of the board for repair. The clips, should they break, may be easily replaced without replacing the entire stif fener as in previous designs. In conventional stiffeners which were bonded to the PCB, cross members of the stiffener were removed to provide necessary wire clearance. This resulted in a board without adequate stiffness and which was difficult to maintain. The alignment clips, which were integrally molded as part of the stiffeners, could be easily damaged necessitating considerable repair to the assembly.
