摘要:
An epoxy resin composition having excellent connection reliability and transparency, a method for manufacturing a composite unit using the epoxy resin composition, and the composite unit, are disclosed. The manufacturing method includes an attaching step of attaching an epoxy resin composition (2) containing a novolak phenolic curing agent, an acrylic elastomer composed of a copolymer containing dimethylacrylamide and hydroxylethyl methacrylate, an epoxy resin and not less than 5 parts by weight to not more than 20 parts by weight of an inorganic filler to 100 parts by weight of the epoxy resin, to a printed circuit board (1) in the form of a sheet. The manufacturing method also includes a temporary loading step of temporarily loading a semiconductor chip (3) and capacitors (4a) to (4d) on the epoxy resin composition (2) and an ultimate pressure bonding step of pressuring the semiconductor chip (3) and capacitors (4a) to (4d) by a thermal bonding head (20) in situ to ultimately pressure bond the semiconductor chip (3) and capacitors (4a) to (4d).

摘要:
A thermally conductive adhesive having: a thermosetting adhesive containing a curable component and a curing agent for the curable component, and a metal filler dispersed in the thermosetting adhesive uses a silver powder and a solder powder as the metal filler. The solder powder to be used has a melting temperature lower than the thermal curing temperature of the thermally conductive adhesive and produces a high-melting-point solder alloy having a melting point higher than the melting temperature of the solder powder when the solder powder is reacted with the silver powder under thermal curing conditions of the thermally conductive adhesive. A curing agent having flux activity to the metal filler is used as the curing agent.
