していた。(Prior art and its problems) Conventionally, Ag brazing preform material has been used to attach a sealing ring to a ceramic container for integrated circuits.
During the rolling and drawing process of the solder, lubricant and surrounding dust may be forced into the surface of the Ag solder, or foreign matter may adhere to the surface during the stamping process, causing foreign matter to float to the surface after brazing. Brazing causes blistering and peeling of the Ni plating and Au plating that is applied afterwards, and it has been difficult to find a countermeasure for this.

As a sealing ring with Ag solder, the impurity residue in the Ag solder floats to the surface, and then the media is made of particles made of metal containing the same components as the Ag solder or one of the components. By polishing the Ag solder sealing ring using the Ag solder, floating residue on the surface of the Ag solder and foreign matter adhering to the surrounding area are removed.
