Printed circuit board of semiconductor package and method for mounting semiconductor package using the same
Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.
