摘要:
A buffer film for multi-chip packaging which does not cause out of alignment during multi-chip packaging and ensures favorable connection reliability has a structure in which a heat-resistant resin layer having a linear expansion coefficient of 80 ppm/° C. or less and a flexible resin layer made of a resin material having a Shore A hardness according to JIS K6253 of 10 to 80 are laminated. A multi-chip module can be produced by aligning a plurality of chip devices on a substrate through an adhesive to perform temporary adhesion, disposing the buffer film for multi-chip packaging between the chip devices and a bonding head so that the heat-resistant resin layer is on a chip device side, and connecting the plurality of chip devices with the substrate by applying heat and pressure to the chip devices toward the substrate with the bonding head.

A light-reflective anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring board contains a thermosetting resin composition, conductive particles, light-reflective needle-shaped insulating particles, and light-reflective spherical insulating particles. Each of the amount of the light-reflective needle-shaped insulating particles and the amount of the light-reflective spherical insulating particles in the thermosetting resin composition is 1 to 50 percent by volume based on the volume of the thermosetting resin composition, and the mixing ratio (V/V) of the light-reflective spherical insulating particles to the light-reflective needle-shaped insulating particles is 1:1 to 10. The light-reflective needle-shaped insulating particles are titanium oxide whiskers, zinc oxide whiskers, titanate whiskers, aluminum borate whiskers, or wollastonite.

A light-reflective anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring board includes a thermosetting resin composition containing a silicone resin and a curing agent, conductive particles and light-reflective insulating particles. The light-reflective insulating particle is at least one kind of inorganic particles selected from the group consisting of titanium oxide, boron nitride, zinc oxide, silicon oxide, and aluminum oxide. The silicone resin is a glycidyloxyalkyl-alicyclic alkyl-modified organopolysiloxane.
摘要:
A light-reflective anisotropic conductive paste is used as an anisotropic conductive paste when a light-emitting device is produced by flip-chip mounting a light-emitting element such as a light-emitting diode element (LED) on a wiring board. The light-reflective anisotropic conductive paste includes light-reflective insulating particles, in order to improve light emission efficiency without providing, in the LED, a light-reflecting layer that causes an increase in manufacturing cost. With the light-reflective anisotropic conductive paste, a reduction in bonding strength of the light-emitting element to the wiring board in a high-temperature environment can be suppressed, and a reduction in conduction reliability after a TCT can also be suppressed. In the light-reflective anisotropic conductive paste, conductive particles and the light-reflective insulating particles are dispersed in a thermosetting resin composition. The thermosetting resin composition contains an epoxy compound and a thermal catalyst-type curing agent.
