Abstract: A bonding apparatus and method of bonding copper bond wires to bond pads on an integrated circuit devices attached to a substrate. A heater block heats the devices and substrate prior to and during wire bonding. A clamp presses the substrate down onto the heater block during wire bonding and thereby forms a region of the substrate isolated from the remainder of the substrate. A bonder head creates ball bonds as it attaches one end of the bond wires to the bond pads on the devices within the isolated region. The bonder head also attaches the other end of the bond wires to substrate pads adjacent the devices being wire bonded. To prevent corrosion of the ball bonds, a gas source floods the substrate and the attached devices that have not yet wire bonded with a purge gas while the heater block heats the substrate and the attached devices.

Abstract: In a distributed or multi-user system, it is possible for a user to try to access a media file that is not optimal for the user's purposes. In other words, the best quality version of some source material might not be the most optimal version for all users. For example, some users might use less network bandwidth if they used lower resolution video data. User context information is used to limit which versions of a source may be provided to a user that requests the source. The system interprets the user context information to provide the best quality version of the source for the user's purposes. Example user context information may include a specified working resolution and/or a specified target resolution for the user. The context information may be specified for the user or may be specified for a group of users, location of the user or other characteristic related to the user, from which the user in turn inherits the context information.
