    摘要: The present invention concerns adhesive compositions that provide corrosion-preventative properties and improved adhesive bonding on corrodible surfaces, such as may be found in electronic components. These compositions provide the substrates with greatly increased resistance to corrosion, especially during long term exposure to high temperatures and/or high humidity. When used on conductive substrates, the compositions also maintain good initial and ongoing electrical conductivity.

    摘要: A method and apparatus for encoding/decoding information using low density parity check (LDPC) codewords of varying lengths. In one implementation, an encoder/decoder uses a parity check matrix having a size that corresponds to a length of information for each codeword. In one example, the size of the parity check matrix may be retrieved from multiple stored matrices having different sizes. In other examples, a mother code matrix may be dynamically adjusted by puncturing parity bits and/or deleting information bits. Other inventive embodiments and adaptations are also disclosed.

    摘要: An anisotropic conductive adhesive that provides strong adhesion to metals and organic substrates to generate stable and reliable electric interconnects. The adhesive provides the benefits of short thermocompression bond time at low temperatures. The adhesive contains cationic curable resin, latent cationic catalyst that thermally cures the resin at high speeds and low temperatures, conductive filler, optionally a film forming thermoplastic solid resin and optionally nano size filler. The optional nano filler provides the benefit of reducing the coefficient of thermal energy mismatch, improving the adhesion strength and reducing the total heat of reaction for the system.
