  • Publication number: 20250108469
    Abstract: An apparatus for machining a web made of electrode material includes a track extending continuously between a web path and an offload path, and supports operatively coupled to the track and moveable continuously along the web path and the offload path. The track is operable to control a conveying speed of each support along the web path. Each support includes a work surface that engages with the web at a first end of the web path to convey the web in the down-web direction at the conveying speed along the web path between the first end and a second end of the web path. The web is disengaged from the work surface at the second end of the web path. The apparatus also includes a machining device operable to act on the web as the web is conveyed in the down-web direction at the conveying speed along the web path.

  • Publication number: 20160071259
    Abstract: Automated optical inspection of a wearable device and/or sub-assemblies of the wearable device in-situ in an ambient environment where temperature and ambient lighting are need not be controlled are described. A key gold unit for the wearable device or a subassembly of the wearable device may be mounted to an automated optical inspections system that captures images of the key gold unit, converts the image from a color space it was captured in to a Hue, Saturation and Value/Brightness color space. Units under test are imaged while stationary or while being rotated (e.g., 360 degrees) and are imaged. Image data is converted into the Hue, Saturation and Value/Brightness color space and compared with the data from the key gold unit to determine if the unit under test is color matched with the key gold unit. Functionality such as near field communications, capacitive touch, display functionality and others may be tested.

  • Patent number: 7357694
    Abstract: Techniques for singulating a substrate into a plurality of component parts is disclosed. The singulation techniques include generating a jet stream in order to cut through large components so as to produce smaller components. The techniques are particularly suitable for singulating surface mount devices such as chip scale packages, ball grid arrays (BGA), flip chips, lead less packages (QFN) and the like. The techniques are also suitable for singulating photonic devices.

  • Publication number: 20060180579
    Abstract: A single multidirectional chuck for use with a cutting beam such as a fluid jet is disclosed. The single multidirectional chuck includes a first set of cutting slots oriented in a first direction and a second set of cutting slots oriented in a second direction that is transverse to the first direction. One set of cutting slots extends entirely through the chuck so that the cutting beam may pass therethrough. The other set of cutting slots, which are transverse to the first set, only extend partially into the chuck. The partially extended cutting slots each provide a space that leads to a sacrificial member housed with a cavity in the single chuck. During a cutting operation, the cutting beam passes through the partially extended cutting slots and bombards the sacrificial member. The sacrificial member is configured to sacrifice itself in order to protect the structural components of the chuck.
