摘要： A spray coatable adhesive composition used for bonding silicon dies to a rigid substrate, preferable a silicon substrate is disclosed. The adhesive composition includes an epoxy based resin, a thermal acid generator, a photoacid generator and a solvent. The epoxy based resin includes a mixture of a solid bisphenol A epoxy resin and a liquid or semi-liquid hydrogenated bisphenol A epoxy resin at a weight ratio ranging from about 80:20 to about 65:35. The adhesive composition has a low viscosity which allows it to be spray coated on a rigid substrate and form thin film adhesive which allows silicon dies to be bonded with precise placement on the silicon substrate.

摘要： A dynamic and flexible architecture and methods for demodulation of high data-rate streams with high symbol-rates, such as in satellite communications systems or computer network communications systems, is provided. A data stream of a data transmission is received, the data stream corresponding to a plurality of data symbols. A plurality of data samples corresponding to each of the data symbols is generated. Further, one or more representative data samples, corresponding each of the data symbols, are generated based at least in part on timing control signals and the generated data samples for the respective data symbol. The generated data samples corresponding to each of the data symbols other than the representative data samples are dropped. The timing control signals are then adjusted based at least in part on the generated representative data samples.
