Abstract: An assembly and method for detecting defective and open solder joints of an area array packages attached to a printed circuit assembly is presented. The assembly employs offset pad layout on either or both of the printed circuit assembly or the area array package allowing improved solder joint defect detection.
Abstract: A system for processing a high definition television signal includes a codeword prioritizer responsive to a codeword datastream derived from an MPEG-like encoder. The prioritizer generates a flag to indicate a breakpoint between high priority and standard priority codewords within a given image data group. Null codewords are inserted into the codeword datastream during intervals when the prioritizer is analyzing codewords to determine where to establish the priority breakpoint. The null codewords are ignored by a following transport processor which packs codewords into cells.
