    Abstract: A camera module includes a lens assembly, a lens holder, and an image sensor assembly. The lens assembly includes a lens barrel and multiple lens elements embedded within the lens barrel. A change of temperature causes an optical focal shift that is determined according to an optical thermal shift rate associated with an optical design of the lens assembly. The lens holder has a lens holder CTE to compensate for the optical focal shift by thermo-mechanical expansion. The change of temperature causes a length expansion of the lens holder determined at least in part according to the lens holder CTE. The image sensor assembly includes an image sensor and a substrate coupled to the image sensor, the image sensor to capture light passing through the multiple lens elements and convert the captured light into image signals. The lens holder is attached to the lens barrel and the substrate using adhesives.

    Abstract: A hybrid sensor shift platform for an optical image stabilization (OIS) actuator mechanism in compact camera modules includes two or more substrates. A top substrate is composed of an organic material (e.g., a resin) to reduce mass, reduce magnetic interaction with permanent magnets, and improve reliability. One or more lower substrates of the hybrid sensor shift platform are ceramic substrates that provide the benefits of ceramics for connection to the image sensor. The organic substrate is connected via a solder bond process to the lower ceramic substrate(s). The connection between the substrates is reinforced with an under-fill of epoxy that surrounds the solder bonds, thus creating a full interface between the substrates within the overlap.

    Abstract: A camera may use a multi-axis image sensor shifting system to implement both autofocus (AF) and optical image stabilization (OSI) functions. The multi-axis image sensor shifting system may include a flexure suspension arrangement and an actuator. The flexure suspension arrangement may include an inner frame, an intermediate frame, and an outer frame. The actuator may include one or more magnets, and two sets of one or more coils attached respectively to some of the frames of the flexure suspension arrangement. Current flowing through the coils may be regulated to interact with the magnetic field of the magnets to generate motive force to move an image sensor of the camera relative to a lens group in multiple directions.

    Abstract: Various embodiments include an interlock arrangement that may be used to attach a lens barrel to a lens carrier of a camera. In some embodiments, the interlock arrangement may restrict movement of the lens barrel relative to the lens carrier along at least an optical axis. In various examples, the interlock arrangement may include one or more grooves and one or more protrusions. For instance, a groove may be defined by the lens barrel or the lens carrier, and a protrusion may extend from the lens barrel or the lens carrier to at least partially into the groove. In some cases, the interlock arrangement may include an adhesive that at least partially fills gaps within the interlock arrangement between the lens barrel and the lens carrier. According to some embodiments, the interlock arrangement may include one or more recesses that provide inlets for the adhesive to be introduced to the gaps within the interlock arrangement.

    Abstract: In some embodiments, a camera actuator includes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor includes a lens carrier mounting attachment moveably mounted to the actuator base, a plurality of shared magnets mounted to the base, and an autofocus coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of one or more lenses of the lens carrier. In some embodiments, the optical image stabilization voice coil motor includes an image sensor carrier moveably mounted to the actuator base, and optical image stabilization coils moveably mounted to the image sensor carrier within the magnetic fields of the shared magnets, for producing forces for moving the image sensor carrier in a plurality of directions orthogonal to the optical axis.

    Abstract: Passive dampers (e.g., a viscoelastic material such as a silicon gel) may be applied at one or more locations within an actuator module along wires suspending a moving component (an optics assembly) from a fixed component (e.g., a base of an actuator module). The passive dampers act to passively dampen the motion of the optics assembly on the XY plane within the actuator module during optical image stabilization (OIS) of the optics assembly when subjected to external excitation or disturbance, and may also provide Z (optical) axis damping and impact protection. Process control and automation manufacturing and assembly methods for an OIS voice coil motor (VCM) actuator module including passive dampers are described, as well as design elements that provide for the integrity and reliability of the passive dampers over the life cycle of the actuator module.
