Abstract
A method includes modifying wettable regions of a leadframe with a laser to form non wettable barriers. Wettable pads are defined with the non wettable barriers. Since the non wettable barriers are formed in a single automated step with the laser, the non wettable barriers are formed at low cost. During flip chip mounting of an electronic component to the leadframe, the non wettable barriers confine solder to the wettable pads. This results in consistent and reliable solder bump formation.
