Abstract: A high efficiency thermal interposer (150) comprising a first hollow disk (160) and second hollow disk (161), held together by thermally isolating fasteners (162, 163). The fasteners keep the disks from touching one another. In an illustrative embodiment of the invention, the first disk is the low temperature disk portion and the second disk is the high temperature disk portion of the heat shield. Furthermore, according to a preferred embodiment of the invention, the space between the disks is filled with small thermally conductive particles (185) (e.g., stainless steel spheres) which are in thermal contact with the high temperature disk but which are not in contact with the low temperature disk. The thermal interposer/heat shield includes means (135) for introducing cold jets of air into the cavity containing the particles, means for circulating (169) the air therebetween, and means through which the air can exit from the cavity to carry away the heat picked up from the particles inside the cavity. The novel thermal interposer has a low mass, is compact and can achieve a temperature drop that will permit high powered HAT devices to be used in conjuction with temperature sensitive electronic orientation means, such as robot arms.

Abstract: A matrix addressed display system designed so as to enable data line (22) repair by electronic mechanisms which is efficient and low in cost and thus increases yield. Such active data line (22) repair utilizes additional data driver (36) outputs, a defect map memory (48) in the TFT/LCD module and modification of the data stream to the data drivers (36) by additional circuits (42) between the display and the display adapter. A bus configuration on the display substrate is utilized which combines repair flexibility, low parasitic capacitance, and the ability to easily make the necessary interconnections. The number of interconnections is kept to a minimum, the connections are reliable, and the connections may be made with conventional wire bond or laser bond technology, or disk bond technology.

Abstract: A method and apparatus for removing wires bonded between chip contact pads (60) and substrate contact pads (10) using an alternating fluid flow is described. The fluid flow is preferably air. A nozzle having a plurality of air jets within a chip accommodating cavity is disposed over the chip to enclose the chip contact pads, the substrate contact pads and the wires bonded therebetween. Air is forced through the plurality of jets to cause an alternating clockwise and counter clockwise air flow which bends the plurality of wires back and forth until they fatigue at the contact points to the chip contact pads in a substrate contact pads which results in the wires being substantially simultaneously severed therefrom. The nozzle has an aperture out through which the air escapes carrying the severed wires therewith for collection in a filter.

Abstract: A hitch feeder for a TAB tape is described which comprises: a stationary jaw assembly (12) having opposing jaws for gripping edges of the tape when closed, and not gripping the edges when open; a movable gripping assembly (10) which includes a lower movable gripper positioned below the tape (22) and an upper movable gripper positioned above the tape. The lower and upper movable grippers may be moved both towards and away from the tape, each said movable gripper gripping the tape when moved towards it and releasing the tape when moved away from it. Both grippers are physically clear of any features on the tape when moved away from it. A tape feeder is provided for reciprocally moving the movable gripper assembly along the tape length, both towards and away from the stationary jaw assembly. A feed control is operative when the movable gripping assembly moves towards the stationary jaw assembly, to move the gripper jaws to grip the tape and to open the opposing jaws, and is further operative when the movable gripper assembly moves away from the stationary jaw assembly, to move the gripper jaws away from the tape and to close the opposing jaws.
