  • Patent number: 9999125
    Abstract: The present application discloses a method for fabricating ceramic insulator for electronic packaging, and relates to a technical field of outer shell packaging of electronic devices. Under the circumstance of using neither a chemical coating nor any bonding wire connection circuit, through a design that builds a electroplated circuit into the ceramic insulator, the method accomplishes coating of a nickel alloy protection layer onto a porcelain by an electroplating method, so that not only quality of a coating layer but also requirement of a complete appearance can be ensured. All circuits of the ceramic insulator fabricated by the aforesaid method can conduct with external circuits, such that the electroplating method can be used to accomplish coating of the nickel alloy layer, after accomplishment of all metal coating, metallization parts on an end surface of the porcelain is removed.
