What is Laser Bonding? Laser Bonding is a marking process that produces permanent marks on a variety of surfaces including metals, glass, ceramic, and stone without damaging the surface. Typically performed with a CO2, fiber, Nd: YAG, or DPSS laser systems, laser bonding technology has enabled manufacturers to automate their marking operations.
Laser assisted bonding for semiconductor die interconnections is disclosed and may, for example, include forming flux on a circuit pattern on a circuit board, placing a semiconductor die on the circuit board where a bump on the semiconductor die contacts the flux, and reflowing the bump by directing a laser beam toward the semiconductor die.
