  • Publication number: 20230400297
    Abstract: A camera module is manufactured by attaching a lens module to an image sensor. The lens module includes at least one lens element which has a plurality of centers of curvature. A tilt angle of an imaging axis of the image sensor is determined, and a tilt angle of an optical axis of the lens module is also determined by using an optical device to identify locations of multiple centers of curvature of the at least one lens element included in the lens module. At least one of the lens module and the image sensor are then adjusted accordingly so that the imaging axis and the optical axis are aligned, and thereafter, the lens module is fixedly attached with respect to the image sensor to form the camera module.

  • Patent number: 10096568
    Abstract: Disclosed is a die bonding tool comprising: a rigid body; and a collet having a die-holding portion; wherein the collet is mechanically coupled to the rigid body by a flexible element which is configured to angularly deflect relative to the rigid body on application of a torque to the collet and/or to a die held by the collet. Also disclosed is a die bonding system comprising the die bonding tool, and an adhesive dispenser for a die bonding system.

  • Publication number: 20130011941
    Abstract: A semiconductor die is attached onto a substrate on a process platform during manufacturing of a semiconductor package. A dispenser dispenses an adhesive onto the substrate, and the semiconductor die is bonded onto the adhesive which has been dispensed onto the substrate with a bonding tool. Thereafter, a bond line thickness between a bottom surface of the semiconductor die and a top surface of the substrate on the process platform is measured using a measuring device.
