Classification: CPC H | IPC H

Claim 17:
18. The method according to claim 12, the copper, nickel, gold or silver is electroplated onto the ceramic substrate and the ceramic enclosing plate in the alignment fit state, wherein in the electroplating, an electroplating energizing mode comprises:
providing an electroplating electrode on a surface of the ceramic enclosing plate facing to the ceramic substrate and supplying power by the electroplating electrode, to perform electroplating; or
providing an electroplating electrode on a surface of the ceramic substrate facing to the ceramic enclosing plate and supplying power by the electroplating electrode, to perform electroplating; or
providing an internal electroplating electrode and an external electroplating electrode electrically connected with each other on the ceramic substrate, and supplying power by the external electroplating electrode, to perform electroplating, wherein the internal electroplating electrode is located on the surface of the ceramic substrate facing to the ceramic enclosing plate, and the external electroplating electrode is located on a surface of the ceramic substrate facing away from the ceramic enclosing plate.
