Abstract: A film-coated optical fiber photovoltaic conversion module includes a multi-chip package, laser welding spots, a PCBA, film-coated optical fibers, coatings, lasers, and gratings. The multi-chip package is fixedly connected to a top portion of the PCBA; the multi-chip package is provided with a metal bonding pad allowing welding of the lasers; the metal bonding pad is further provided with the laser welding spots; and the coatings are coated outside the film-coated optical fibers. The film-coated optical fiber photovoltaic conversion module based on the multi-chip package technology combines the multi-chip package with the film-coated optical fibers to omit a conventional COB process; a structure design is reasonable such that the film-coated optical fibers disposed at a 45° bevel is docked with the Vcsel lasers to allow direct refraction of light into the optical fibers.

Abstract: A multi-chip package design module includes a first circuit board and a multi-chip package. The multi-chip package is installed on a top portion of the first circuit board; the multi-chip package includes a second circuit board; an optical chip is welded to a top portion of the second circuit board; the multi-chip package further includes a drive chip welded to the second circuit board; the drive chip and the optical chip are externally and fixedly provided with an epoxy molding compound; and the multi-chip package further includes two power supply pins fixedly connected to a bottom portion of the second circuit board. The application combines the multi-chip package with a glass V-groove design to omit conventional COB and coupling processes, which can simplify and standardize a product structure.
