  • Publication number: 20230405712
    Abstract: The present invention relates to a turntable-type probe pin laser bonding apparatus. More particularly, a dual laser optic module of the turntable-type probe pin bonding apparatus of the present invention provides an integrated dual laser optic module that is overlappingly irradiated on a co-focus by improving the conventional first and second laser optic modules that have been completely separated and arranged independently with different focal points. During laser bonding of probe pins, which are getting miniaturized day by day, the power and density of the first and second laser beams overlappingly irradiated from the integrated dual laser optic module can be precisely controlled so that a turntable-type probe pin laser bonding apparatus of the present invention can significantly improve the bonding defect rate, as well as contribute to high integration and high precision of the apparatus.
