A SMT tape includes a carrier tape, a number of separation pads, a number of workpieces, and a package tape. The carrier tape includes a package surface and defines a number of receiving grooves in the package surface and arranged along a length direction of the carrier tape. The separation pads are received in the receiving grooves and fixed to bottom surfaces of the receiving grooves respectively. Each separation pad includes a separation surface opposite to a bottom surface of the corresponding receiving groove and a number of protrusions protruding up from the separation surface. The workpieces are respectively received in the receiving grooves. Each workpiece includes a main body and an adhesive layer positioned between the corresponding separation pad and the main body. The package tape is adhered to the package surface and seals the receiving grooves.

An apparatus for assembling camera modules to flexible printed circuit boards (PCBs) includes a number of trays, a surface mounting device used in surface mount technology (SMT) for PCBs, and a hot pressing device. Workpieces, each of which includes a flexible PCB (FPCB) and a lens module positioned on the FPCB, are received in the trays. Each tray is sent to the surface mounting device. The surface mounting device loads and pastes a stiffener onto a FBCB, opposite to a lens module. The hot pressing device hot presses each stiffener to the respective workpiece, which is received in each tray sent from the surface mounting device, to fixedly secure the stiffener to the respective workpiece to form a camera module.

A flexible printed circuit board (FPCB) assembly includes a FPCB, a dielectric layer, a stiffener, and a conductive adhesive layer. The FPCB includes a surface and a conductive layer positioned on the surface of the FPCB. The conductive layer includes a circuit portion and a grounding portion connected to the circuit portion. The circuit portion is entirely covered by the dielectric layer and the grounding portion is exposed outside the dielectric layer. The conductive adhesive is positioned on the stiffener and includes a first adhering portion and a second adhering portion. A thickness of the second adhering portion is greater than the first adhering portion. A thickness difference between the second adhering portion and the first adhering portion is substantially equal to a thickness the dielectric layer. The first adhering portion is adhered to the dielectric layer and the second adhering portion is adhered to the grounding portion.

Camera module with switchable light filters includes a lens module, a bearing rotating device, a visible light filter, and an infrared light filter. The bearing rotating device includes a rotating shaft, at least one guiding stick, and a bearing plate. The rotating bearing plate holds the two filters and defines an arcuated guiding slot. The circle center of the arcuated guiding slot is the rotating shaft. A visible light filter and an infrared light filter are switchable, their movement being governed by the guiding stick and the guiding slot, to respective alignment with an optical axis of the lens module. The camera module can rotate the bearing plate to switch the infrared filter for the visible filter where the acquisition of infrared light is required.
