Abstract: Semiconductor dice from a scribed wafer are first separated by a stretched cloth. The dice on the stretchable cloth are then lined up with a target unit and transferred by pressure to a target unit to form a matrix. The pressure can be exerted by pressing individually the dice from the stretchable cloth to the target unit. Alternatively, the dice from the stretchable cloth can first be transferred to a transfer unit before being compressed to the target unit. The transfer unit may also be a perforated board to the hold the dice in place before the dice are soldered to the target unit.
Abstract: A dispensing nozzle device for dispensing processing materials to an output region, includes a body and a plurality of first conduits. The body is formed with a first chamber, a second chamber, a plurality of through holes in communication with the first chamber and the second chamber, and a dispensing nozzle conduit for communicating the second chamber with the output region. The plurality of first conduits are respectively in communication with the plurality of through holes and have a plurality of openings received within the second chamber. A gap is formed between each of the first conduits and corresponding one of the plurality of through holes.
Abstract: A sound generator for storing and reproducing audio signal with reduced memory storage, which is accomplished by: (a) the technique of Adaptive Differential Pulse Code Modulation (ADPCM), and (B) the elimination of silence period from memory storage but regenerating the silence signal at output.
