The image sensor further includes a plurality of bond pads on the upper surface. Interior traces on a lower surface of a step up ring are aligned with the bond pads on the upper surface of the image sensor.

Abstract: A pressure gauge or monitor is attached to a soldering iron so that the pressure with which the iron is being applied can be precisely monitored. Such a pressure monitor on a soldering iron can be used to monitor the pressure applied with the soldering iron when forming a solder electrode on an anti-reflective film of a cathode ray tube. This allows such electrodes to be consistently and optimally formed for grounding the anti-reflective film.

In that method, a first selected material is disposed on the components to facilitate the deposition of solder. Subsequently, solder is disposed on that material and the component is aligned. A laser beam is properly focused on the solder such that the solder melts and, when the laser beam is turned off, hardens, thereby fixing the component in the desired position.

Abstract: By utilizing a roll bonding process and appropriately forming steps, a load bearing structure is created which is capable of handling and appropriately transferring loads. One preferred method includes the combination of roll bonding and hydroforming to efficiently create structural components. While various product configurations are possible, one version includes a waffle-type structure produced by appropriate roll bonding of material sheets. This waffle-type structure can also undergo additional forming steps to create several structural components capable of handling and carrying loads in a very efficient and effective manner. More significantly, this process enables the use of structural aluminum for load bearing components which are efficiently and cost effective when manufactured.

Abstract: A method and machine for deburring the burr which is formed when wires are butt welded is disclosed. The machine comprises a deburring head which has a pair of opposed deburring rollers mounted thereon. Each of the rollers has a milled surface formed therein. A linkage is connected to the rollers to cause the rollers to rotate when the linkage is moved between first and second positions. When the linkage is in its first position, the milled surfaces of the rollers face one another to enable the wires and burr to be positioned therebetween. As the linkage moves to its second position, the circumferences of the rollers engage the burr to roll out the same, thereby providing a substantially smooth, cylindrical surface where the burr was located. The method of deburring is also disclosed.

Abstract: A method of producing a ball bump on a workpiece employs a capillary having a passageway therethrough. A wire extends through the passageway and has a ball formed on its end below the capillary. The capillary is positioned above a bond site and is lowered until the ball contacts the bond site. The capillary simultaneously applies ultrasonic energy and a downward force against the ball to deform the ball to a ball bump and bond it to the bond site. The capillary is thereafter displaced in a first direction to break the wire away from the ball bump. The capillary is then displaced in a second direction across the ball bump to engage any residual wire protruding from the ball bump surface and substantially smooth the residual wire against the ball bump surface.
