Abstract: A method of selectively adjusting surface tension of a soldermask material. Specifically, a method of selectively adjusting the surface tension of a soldermask material to promote adhesion of a molding compound in a ball grid array package while maintaining a low surface tension on the ball attach area to prevent bridging between the solder balls. Solder balls require a low surface tension soldermask to minimize bridging, while the molding compound requires a high surface tension to provide adequate adhesion to the surface of the soldermask. By exposing selected portions of the soldermask to an activation method, such as ultra-violet radiation, the surface tension of the soldermask can be varied such that different areas of the package exhibit different surface tensions.

Abstract: One or more techniques are provided for deriving motion data from a set of CT projection data. The techniques calculate moments associated with consistency conditions for the projection data to derive motion data from the projection data. One aspect of the present techniques uses the calculated moments to select projection data sets based upon the presence or absence of motion between the projection data sets.

Another aspect of the present techniques uses projection data acquired by a slowly rotating volumetric CT gantry to allow the separation of a corruptive signal from a desired motion signal. Once separated, the desired motion signal may be used to identify projection data at a desired phase of motion.
