Document Type and Number:
WIPO Patent Application WO/2007/034893
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a pasty metal particle composition from which a solid metal
excelling in strength, electrical conductivity and thermal conductance is
obtained through sintering of metal particles within an extremely short period
of time; a method of hardening the pasty metal particle composition; etc. [MEANS
FOR SOLVING PROBLEMS] There are provided a pasty metal particle composition
comprising metal particles of 0.1 to 30 μm average particle diameter and
2.0 wt.% or less carbon content and a volatile dispersion medium; a method of hardening
a pasty metal particle composition, comprising applying supersonic vibration
to the composition under pressure, especially under pressure and heating, to
thereby evaporate the volatile dispersion medium and thus effect sintering
of the metal particles; a method of bonding metal members, comprising interposing
a pasty metal particle composition between metal members and applying supersonic
vibration thereto under pressure, especially under pressure and heating; and
a process for producing a printed wiring board, comprising applying supersonic
vibration to a pasty metal particle composition on a substrate under pressure,
especially under pressure and heating, to thereby form a metal wiring.
