Abstract: A wire bonding capillary (1), which is able to decrease wire extraction resistance and suitable for a long and low loop wire bonding process, comprises a through bore (5) for feeding a bonding wire, a funnel-shaped bore (3) for guiding the wire to the through bore, and a tapered portion (11) formed at an exit of the through bore. The through bore length is between 0.2 and 1.5 times the through bore diameter. The tapered portion is tapered in two steps.

Abstract: In measuring the position of a bonding tool accurately in offset correction in a bonding apparatus, the tool is moved to approach a reference member, the tool is illuminated with a reference pattern by a laser diode, and the deviation between the reference member and tool in one horizontal direction is measured based upon the image of the reference pattern projected on the tool. A position detection camera images the tool in another horizontal direction, thus measuring the deviation of the tool and reference member. The position detection camera is moved to approach the reference member, and the deviation between the position detection camera and the reference member is measured by the position detection camera. The accurate offset amounts between the position detection camera and the tool are determined based upon these measured values and amounts of movement of the position detection camera and the tool.

Abstract: A chip carrier and lid are sealed by mounting the chip carrier in an inverted position and mounting a lid having a sealing preform in an inverted position beneath and facing the chip carrier. The chip carrier and lid are then heated to melt the sealing preform and the chip carrier and lid are moved together to join them at the sealing preform.

Abstract: An installation for positioning and welding body parts of different types of motor vehicles. The installation includes a mounting frame (5) which is guided on a conveyor line and which has receiving elements for at least some vehicle body parts. Positioning devices (8) are provided for the vehicle body parts (6) and at least one robot is provided for carrying out welding work. The invention is very flexible in terms of product modifications. The mounting frame (5) has positioning devices for at least some vehicle body parts (6) and clamping devices for the vehicle body parts. An additional (lower) conveyor line (10) is located under the first conveyor (2). One of several auxiliary mounting frames (12) is guided on the additional conveyor line. Parking positions (13) for the auxiliary mounting frames (12) are provided next to the lower conveyor line (10).

Abstract: A back-up tooling apparatus for supporting the inner side of a hollow cylindrical workpiece during a circumferential friction stir weld includes a plurality of arcuate shoes configured to mate end-to-end to form a substantially continuous ring, and an expandable support for supporting the shoes and operable to retract and expand the shoes inward and outward. The expandable support includes at least one rotatable feed screw and central support members mounted on the feed screw or screws and pivotally connected to the shoes by support arms. The central support members are moved axially toward or away from each other for expanding or retracting the shoes. The shoes in one embodiment overlap in the circumferential direction, and a seal material is disposed between mating end faces of adjacent shoes. A restraining device is provided for clamping about the workpiece to reduce thermal expansion thereof. Cable-and-winch and geared drive devices are provided for rotatably driving the workpiece from its outer surface.

Abstract: Apparatus for connecting a first area array component to a substrate with a joining material. The apparatus has a nozzle directing heat toward both the first area array component and the portion of the substrate beneath the first area array component to melt the joining material. An elastic seal contacts the substrate and prevents the heat from affecting other components adjacent the first area array component. The nozzle is pressed against the substrate to restrain warping of the substrate, which might be caused by the heating of the first area array component, and to prevent damage to the substrate. The nozzle can tilt so that it conforms to the surface of the substrate. The first area array component is allowed to move freely in the direction of a plane of the substrate under the surface tension of the molten joining material during heating to center the first area array component.

Abstract: A vehicle body welding system includes a work station for welding components of a preassembled body with respect to one another. The body is moveable along a fixed path of travel through the work station. At least two moveable pillars are located on each side of the fixed path of travel through the work station for synchronized reciprocation between first and second end limits of travel toward and away from the fixed path of travel of the body. At least one gate is connectible in a repeatable located position with respect to the moveable pillars on each side of the fixed path for synchronized reciprocation between first and second positions toward and away from the fixed path of travel of the body. Locating members are engageable between each pillar and the corresponding gate for locating the gate with respect to the moveable pillar in at least two dimensions.

Abstract: The invention concerns a method and a device for feeding, clamping, and processing, particularly for geometric welding of automobile body components in a work station. The invention method consists of side-section clamping frames which, after receiving a body side section with the help of portal robots which travel along an elevated four-axle portal in the X-Y axis, are brought into the geometrical welding station, positioned at both sides of the body conveyer system for geometrical welding. The device is characterized in that a four-axle portal (2) is arranged above the geometrical welding station and along which four-axle portal (2), on each side of the body conveyer system (1), at least one portal robot (3), from which side-section clamping frames (9) are hung, can travel in the X-Y axis between a position for receiving the body side sections (8) and a position for clamping and welding the body.
