A method for inspecting a component includes exciting a number of transducers forming an array to produce an ultrasonic transmission beam (beam) focused into the component. The array and the component are separated by a standoff. A number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture on receive, both of which compensate for refraction of the beam at the component/standoff interface. A single-turn inspection method includes: (a) positioning the array facing the component, (b) exciting the transducers, (c) generating a number of echo signals, (d) changing the relative angular orientation of the array and the component around an axis and repeating steps (b) and (c), and (e) processing the echo signals to form at least one processed echo signal.

Complex equipment operated by a plurality of computerized task functions is coupled to a host processor which controls operation of a plurality of task functions performed by the equipment. Included in the equipment are a plurality of client processors, a communications network coupling the host processor to the client processors, and a plurality of programs providing respective task interfaces for running selected task functions of the equipment on any of the client processors as remote processes. Each task interface program includes a library of communications handlers and a designated task interface. When the complex equipment comprises an ultrasound imager system, the task functions of shaping a transmit waveform and shading the transducer reception parameters are performed through preferred embodiments of such task interfaces. A voice input task function may also be run as a remote process coupled to the imager host through the network interface.

A method for optimally operating a computer numerical control (CNC) milling machine to form cavities in a ceramic substrate for receiving IC chips and other components of a high density interconnect structure electrically interconnected by a multi-layer interconnect (HDI) structure. Generation of the CNC program instructions is based on locations and dimensions of the components which, through a set of design rules, provide locations and dimensions for an initial set of cavities corresponding to the components on a one-for-one basis. Depending upon the particular arrangement of the components, specific neighboring cavities of the initial set may either overlap or be separated by walls. A representation of the location and dimensions of each of the cavities of the initial set is formed, and the representation is enhanced by a 'combine pockets' step and by a 'remove borders' step to represent locations and dimensions of cavities of an optimized set. CNC program instructions for the milling machine are then generated for forming the cavities of the optimized set.

Halides of aluminum or tin, or other metals, in combination with sodium chloride in the presence of mercury and excess aluminum or tin metal are used as a fill material in a solenoidal metal halide arc lamp. This fill results in very good color and a high efficacy.
