发明名称 Conductive connection structure formed on the surface of circuit board and manufacturing method thereof
摘要 The conductive connection structure of the present invention comprises a circuit board, a plurality of conductive pads, a solder mask layer, an electroless plating copper layer, and an electroless plating adhesive layer. The manufacturing method comprises the following steps: providing the circuit board having a plurality of conductive pads thereon; forming the solder mask layer, the electroless plating copper layer, and the electroless plating adhesive layer respectively on the surface of the circuit board, and forming a solder bump on the electroless plating adhesive layer. By the assistance of the conductive connection structure and the manufacturing method thereof, cavity otherwise formed on the conductive pads can be prevented, and the solder bumps therefore are firmly fixed on the conductive pads. Moreover, the stress in the surface between the solder bump and the conductive pad can be reduced as the semiconductor chip and the circuit board are combined.
