Laser soldering repair process laser soldering process and laser soldering system

摘要

A laser soldering repair process, a laser soldering process, and a laser soldering system are disclosed. The laser soldering repair process, which is to perform a repair process using a laser in a repair region where a soldering process is not performed among soldering regions on a substrate, includes a step of performing a laser cleaning process by emitting a cleaning laser beam to the repair region of the substrate, a step of providing a solder ball in the cleaned repair region of the substrate, and a step of heating the solder ball to attach the solder ball to the repair region by emitting a soldering laser beam to the solder ball. It is possible to simplify the configuration of the laser soldering system.
