发明名称 Repaired structure of circuit board having pre-soldering bump and methods for repairing the same
摘要 A repaired structure of a circuit board having pre-soldering bumps and a method for repairing the same are proposed. Firstly, a circuit board having a plurality of pre-soldering bumps on a surface thereof is provided, wherein at least one of the pre-soldering bumps has a defect. Then, a micro-electroplating process or a micro-electrolyzing process is performed by a micro-electrode nearby the defective pre-soldering bump, so as to repair the defective pre-soldering bump. Therefore, the present invention is able to enhance the process yield and reduce the production cost.
