Abstract
Provided is a metal powder sintering paste having a high resistance to thermal stress. The present invention provides a metal powder sintering paste containing silver particles having an average particle diameter (median diameter) of 0.3 μm to 5 μm as a main component, further containing inorganic spacer particles having a CV value (standard deviation/average value) of less than 5%, and containing substantially no resin.
Claims14
A metal powder sintering paste,
- comprising silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm as a main component,
- further comprising inorganic spacer particles having a CV value (a standard deviation/an average value) of less than 5%, and
- comprising substantially no resin.
A method for producing a metal powder sintering paste, comprising:
- mixing inorganic spacer particles having a CV value (a standard deviation/an average value) of less than 5% and silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm together, and substantially not adding resin.
