Lens module, vehicle-mounted panel assembly, and manufacturing method therefor

Abstract

The disclosure discloses a reflow-solderable vehicle-mounted lens module configured to be capable of performing imaging for near-infrared light, the vehicle-mounted lens module including: a lens barrel and a lens group disposed within the lens barrel, the lens group including a plurality of lenses, wherein at least one of the lenses is made of polyetherimide by means of injection molding, the lens made of polyetherimide being injection molded by setting a mold temperature controller at a temperature higher than 265° C.; wherein the near-infrared light has a wavelength ranging from 800 to 1,100 nm, and the highest ambient temperature for the reflow soldering is set at 230 to 260° C.; the vehicle-mounted lens module can ensure stable and consistent performance of a module system before and after undergoing a reflow soldering process. The disclosure overcomes the shortcomings of the existing technology and provides a reflow-solderable vehicle-mounted lens module, which can ensure stable and consistent performance of a module system before and after undergoing a reflow soldering process with the highest ambient temperature of 230 to 260° C., and can satisfy the process requirements for a camera system in DMS.
