Abstract

A method for circuit fabrication includes inspecting an array of solder bumps on a circuit substrate so as to identify a solder bump having a height above the substrate that is greater than a predefined maximum. A first laser beam is directed toward the identified solder bump so as to ablate a selected amount of a solder material from the identified solder bump. Alternatively or additionally, a further solder bump having a height above the substrate that is less than a predefined minimum is identified, and one or more molten droplets of the solder material are deposited on the further solder bump. After ablating or depositing the solder material, a second laser beam is directed toward the identified solder bump with sufficient energy to cause the solder material in the identified solder bump to melt and reflow.
