Abstract: A lens assembly is separated into a first lens module including at least one lens element and a second lens module including at least one other lens element during alignment of its lens elements. Coarse alignment is conducted by aligning an optical axis of at least one lens element within the first lens module with an optical axis of at least one lens element within the second lens module. For conducting fine alignment, an image sensor views a test chart while the first and second lens modules are positioned between the test chart and the image sensor. Image quality indices are obtained from the image sensor of the test chart at different relative alignments between the first and second lens modules, before the first lens module is fixed to the second lens module at a relative alignment therebetween where the image quality indices are optimized.

Abstract: A detape apparatus has a support unit with a deck surface for supporting a tape carrier. The deck surface defines a support plane on which the tape carrier is supportable, and a conveyor is configured to move the tape carrier in a conveyance direction along the deck surface. During a detape process, a receiving segment of a first urging element is movable to a first detape position next to a first side of the tape carrier, while a second urging element is movable to a second detape position abutting the tape carrier on an opposite side of the tape carrier to thereby push the tape carrier out of the support plane to separate at least one electronic component from the tape carrier. The receiving segment may then receive the at least one electric component which is thus separated from the tape carrier.

Abstract: An apparatus for aligning a lens module with an image sensor to form a camera module includes a chart holder, a positioning unit and a reflective elements holder assembly. In use, the chart holder holds a test chart having a region of interest (ROI), the positioning unit holds the lens module and the image sensor, and the reflective elements holder assembly holds multiple reflective elements between the chart holder and the positioning unit. A first optical path from the ROI is directed to a first position on the image sensor. Second optical paths from the ROI are reflected by the reflective elements to respective second positions on the image sensor, the second positions being spaced from the first position. The images captured by the image sensor (arising from the aforementioned optical paths) are analysed and the positioning unit aligns the lens module with the image sensor based on such analysis.
