Abstract: A method of preparing a substrate for substrate bonding is provided. The method comprises: forming a recess in a substrate surface of the substrate, and forming a bondable dielectric layer on the substrate surface of the substrate. The bondable dielectric layer has a bonding surface on an opposite side of the bondable dielectric layer to the substrate surface, wherein the recess and the bondable dielectric layer define a dielectric cavity having a dielectric cavity volume. A plug is formed configured to make electrical contact to the substrate in the dielectric cavity volume. The plug has a plug volume which is less than the dielectric cavity volume, wherein the plug extends from the dielectric cavity beyond the bonding surface in a direction generally normal to the bonding surface. The plug is coined by compressing the substrate between opposing planar surfaces such that a contact surface of the plug is made co-planar with the bonding surface.

Abstract: A camera module has an image sensor and a lens assembly that includes a lens barrel having a first cylindrical portion that includes an externally threaded portion and a second cylindrical portion that has a larger diameter than the externally threaded portion. A lens moving mechanism includes a movable sleeve having internal threads that receive the externally threaded portion of the lens assembly. The lens moving mechanism is coupled to the image sensor such that the second cylindrical portion of the lens assembly is closest to the image sensor. The camera module is assembled by inserting the lens assembly into the lens moving mechanism from the side closest to the image sensor. An installation tool engages the second cylindrical portion to rotate the lens assembly and engage the externally threaded portion of the lens assembly with an internally threaded portion of a movable sleeve in the lens moving mechanism.

Abstract: A camera module includes a body having recesses in a first datum surface. A filleted edge may join the recesses to the first datum surface. An image sensor is coupled to the body at a known distance from the first datum surface. A movable lens mechanism includes a fixed portion and a movable portion. The fixed portion is coupled to the body. The movable portion includes a lens assembly and protrusions arranged to fit within the recesses in the first datum surface and to define a second datum surface. A resilient stop plate covers the recesses in the first datum surface with an elastic sheet material. A spring may hold the protrusions in contact with the resilient stop plate when the movable lens mechanism is unpowered. The resilient stop plate may include a rigid support plate coupled to the body by heat staking. The elastic sheet material may be viscoelastic.
