Document Type and Number:
WIPO Patent Application WO/2015/190501
Kind Code:
A1
Abstract:
A method for sealing a package by putting a lid on the package and bonding the lid to the package with a brazing alloy, the method comprising: a paste application step in which a sealing paste containing a low-melting-point metal powder having a melting point less than 300°C and a high-melting-point metal powder, as another powder, that has a melting point of 300°C or higher is applied to a surface of the lid; a preliminary heat treatment step in which the low-melting-point metal powder in the sealing paste applied to the lid is melted to form a brazing-material precursor; and an alloying step in which the brazing-material precursor is heated and kept molten until the lid is bonded to the package or the brazing-material precursor is heated and melted when the lid is bonded to the package, thereby alloying the brazing-material precursor.
