Assignee: SONGSHAN LAKE MATERIALS LABORATORY
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A method for manufacturing a bracket for packaging a semiconductor device, wherein the method comprises:
providing a first component having a plurality of ceramic substrates arranged in an array, wherein a front surface of each of the ceramic substrates is plated with a first metal plating layer, and a surface layer material of the first metal plating layer is copper, nickel, gold or silver;
providing a second component having a plurality of ceramic enclosing plates arranged in an array, wherein a front surface of each of the ceramic enclosing plates is plated with a second metal plating layer, a back surface is provided with an external electroplating electrode in electrical communication with the second metal plating layer, and a surface layer material of the second metal plating layer is copper, nickel, gold or silver;
aligning the first component and the second component in a manner of bringing the first metal plating layer of each of the ceramic substrates and the second metal plating layer of each of the ceramic enclosing plates to face each other, and providing an internal electroplating electrode in electrical connection with the external electroplating electrode between the first metal plating layer and the second metal plating layer;
connecting to a power supply through the external electroplating electrode, to perform electroplating, so as to form an electroplating layer between the first metal plating layer and the second metal plating layer to connect the two layers; and
cutting the second component which is connected through the electroplating layer, so as to form a plurality of independent brackets composed of the ceramic substrate and the ceramic enclosing plate.
