Abstract:
1. A method for manufacturing a wiring board having bonding pads for flip chip bonding and bonding pads for wire bonding, said method comprising: forming pads to be used as the bonding pads for flip chip bonding and pads to be used as the bonding pads for wire bonding on a surface of a substrate as a workpiece, shielding the pads to be used as the bonding pads for flip chip bonding, and applying plating to a surface of each of the pads to be used as the bonding pads for wire bonding; applying a masking tape to an area, in which the bonding pads for wire bonding are formed, to thereby shield the bonding pads for wire bonding; forming an adhesive layer to a surface of each of the pads to be used as the bonding pads for flip chip bonding, and then providing solder powder to the surface of each of the pads to be used as the bonding pads for flip chip bonding to adhere thereto with the adhesive layer; and peeling off the masking tape from the area in which the bonding pads for wire bonding are formed, and then melting the solder powder by reflowing, thereby to apply the solder to the pads to be used as the bonding pads for flip chip bonding in such a way as to cover the pads to be used as the bonding pads for flip chip bonding.
