A circuit board clamp includes a clamp frame having a first and second frame supports. The clamp frame also includes a top plate arranged between the first and second frame supports. The top plate supports a piston via a threaded fastener engaging a top plate aperture. The piston may be displaced relative to the top plate in accordance with adjustment of the threaded fastener. A pressure plate assembly has a pressure plate and a stem attached to the pressure plate. The stem is positioned within a tubular section of the piston, and the pressure plate is positioned opposite the circuit board from the heat sink. The pressure plate contacts a surface mounted integrated circuit between the circuit board and the pressure plate. A bias member is seated on the bias seat and applies a biasing force on the pressure plate.

System and method for bonding a cable to a substrate using a die bonder

A method of bonding a double-ended cable to a multi-tier substrate (such as a multi-tier printed circuit board) includes picking up the double-ended cable, and imaging alignment markers on a first head of the double-ended cable, a second substrate of the multi-tier substrate, a second head of the double-ended cable, and a first substrate of the multi-tier substrate. The method also includes aligning the alignment marker on the first head of the cable to the alignment marker on the second substrate of the multi-tier substrate, coupling the first head of the cable to the second substrate, and releasing the first head of the cable. The method further includes aligning the alignment marker on the second head of the cable to the alignment marker on the first substrate of the multi-tier substrate, coupling the second head of the cable to the first substrate, and releasing the second head of the cable.

BONDING APPARATUS
20220367404 · 2022-11-17 ·

A bonding apparatus provided with a gas supplying unit for causing an inert gas to be sprayed from a spray aperture provided adjacent to a holding section of the bonding head. The spray aperture is provided so as to surround the holding section of the bonding head, in which a portion of the slits is a wide slit set to a higher jet flow rate of the inert gas than narrow slits of another portion, and the inert gas sprayed from the wide slit and the narrow slits forms an air curtain that surrounds the bonding portion between the semiconductor chip and the substrate. The inert gas sprayed from the wide slit forms a flow that passes between the semiconductor chip and the substrate.

Robotic wire termination system
11502470 · 2022-11-15 · ·

A robotic wire termination system for efficiently and accurately connecting a plurality of wires to an electrical connector having a plurality of connector pins with corresponding wire receptacles. The system generally includes a housing, a removable alignment plate, a robotic positioner, a heating device, a touch responsive display, and a control unit.
