COMPOSITION FOR METAL BONDING

摘要

Provided is a composition for metal bonding, especially a bonding composition containing metal particles, which is capable of achieving high bonding strength by bonding at a relatively low temperature without the application of a pressure, and which has heat resistance and is thus not susceptible to decrease in the bonding strength due to decomposition or deterioration of a resin component when the service temperature thereof is increased. A bonding composition which is characterized by containing two or more kinds of metal particles having different average particle diameters, an organic component and a dispersant, and which is also characterized in that the particle diameter ratio of the average particle diameter (DS) of metal particles (S) that have the smallest average particle diameter to the average particle diameter (DL) of metal particles (L) that have the largest average particle diameter, namely DS/DL is from 1×10-4 to 0.5.

1. A composition for metal bonding, comprising:
two or more kinds of metal particles having different average particle sizes, an organic component, and a dispersant, wherein a particle size ratio (Ds/DL) of an average particle size DS of metal particles S which have the smallest average particle size to an average particle size DL of metal particles L which have the largest average particle size is 1×10−4 to 0.5.
