摘要： An insert for use within integrated circuit (IC) chip carriers to provide universality across device types and applications at a low design and fabrication cost. The present invention functions as a generic carrier floor and/or adaptor insert which enables reception of both quad-flat-pack (QFP) and thin-quad-flat-pack (TQFP) ICs within frames of a variety of existing carriers, or alternatively, may allow both QFP and TQFP ICs to utilize a single IC carrier frame, a feature which currently prevailing embodiments would require two unique IC carriers.

摘要： A clinching assembly for use with an insertion machine of the type used to form and insert the lead-wires of an electronic component into openings of a printed circuit board insertion machine. The clinching assembly includes two clinch heads that are selectively movable along a U-axis, parallel to the circuit board. Each clinching assembly is further selectively movable along a Z-axis, perpendicular to the circuit board. A single pneumatic actuator is used to raise and lower both clinch heads simultaneously. A T-shaped linkage attaches each clinch head with the single pneumatic actuator. Vertical movement of the pneumatic actuator is translated through the T-shaped linkage to vertically displace both clinch heads, and simultaneously, allow horizontal displacement of each clinch head, independent of the vertical location of the T-shaped linkage.
