A leadframe carrier and insert compatible with a temperature-affectable, expandable and contractable leadframe strip to be bonded with a selected plurality of semiconductor chips, said carrier being automatically separable and removable with regard to said insert during manufacture despite possible clinging which may be induced by the expansion and contraction of said carrier insert.

Method for holding a strip of conductive lead frames

Universal leadframe carrier

An apparatus for inverting and handling integrated circuit dice employs rotating apparatus for rotating a chip carrier by 180 degrees to invert and transfer dice from one set of receptacles to another; together with an apparatus for precisely aligning dice resting at random positions within a set of oversized receptacles.

Manipulation and handling of integrated circuit dice

Uniform leadframe carrier

An apparatus for removing selected integrated circuit dice from a wafer array of dice sequentially moves a striker above a tape to the underside of which the array is mounted and then knocks a die down from the array of dice into a receptacle for transport to further processing stages.

An apparatus for gripping a thin flexible object located within a gripping plane having a transverse axis and a longitudinal axis perpendicular to each other and to a linear axis which is perpendicular to the gripping plane, includes first and second sets of gripper claws for gripping the object. The sets of gripper claws are located on opposite sides of the longitudinal axis and are movable between closed and open positions. Means are provided for restricting the motion of the gripper claws in a direction perpendicular to the longitudinal axis so that the gripper claws are prevented from excessive inward movement toward the longitudinal axis beyond a desired predetermined amount. The means for moving the gripper claws to the predetermined desired distance define a gripping volume which is bounded by the gripping claws in the gripping plane along the transverse axis and is bounded in a direction parallel to the linear axis by a top volume bounding surface formed by a back-up bar and by a lower volume bounding surface formed by an inward projection of the gripper claws.
