ABSTRACT:
A protective carrier (2) has a flexible circuit (6) attached thereto, the protective carrier (2) protecting the circuit (6) during transportation and handling thereof. The flexible circuit (6) is attached to the protective carrier (2) in such a manner as to ensure proper registration and to maintain the center of all components in coincidence as dimensional change occurs due to the different temperature coefficient of expansion of each component. The protective carrier (2) can be used to orient, position, and install an integrated circuit chip carrier (8) and lead frame (4) on an interposer socket (30). As the lead frame (4) has a large number of contact zones positioned thereon, contact force is required between the interposer socket (30) and the lead frame (4). Thus, a pressure plate (42) is provided to cooperate with posts (38) and the protective carrier (2) to provide the force required to ensure that a positive electrical connection is effected between the contact zones and the contacts (28) of the interposer socket (30).
