摘要： Lens alignment apparatuses, methods and optical devices are disclosed. In accordance with various embodiments, a lens alignment apparatus may include at least one lens element positioned in a lens body. A lens alignment interface coupled to the lens element may be configured to permit the lens element to be angularly deflected relative to an axis of symmetry of the lens body. In other embodiments, a method of improving the resolution of an optical device may include translating a lens along an optical axis to maximize resolution at a first location, and determining a resolution in a second location in the imaging plane. The resolution in the second location may be improved by angularly deflecting the lens, and the position of the lens may then be fixed.

摘要： An optical sensor package has a transparent substrate with a redistribution layer formed on a face thereof, which includes a window and a plurality of electrically conductive traces. A semiconductor substrate, including an optical sensor and a plurality of contact terminals on a face thereof, is positioned on the transparent substrate in a face-to-face arrangement, with the optical sensor directly opposite the window, and with each of the contact terminals electrically coupled to a respective one of the electrically conductive terminals. The transparent substrate has larger overall dimensions than the semiconductor substrate, so that one or more edges of the transparent substrate extend beyond the corresponding edges of the semiconductor substrate. A plurality of solder balls are positioned on the face of the transparent substrate, each in electrical contact with a respective one of the electrically conductive terminals. The solder balls and the semiconductor substrate are at least partially encapsulated in an encapsulating layer formed on the face of the transparent substrate, which has been planarized to expose upper portions of the solder balls, as contact pads of the optical sensor package.

摘要： On a circuit substrate on which an adhesive is used to couple electronic or structural components to the substrate, an adhesive dam is positioned to prevent the adhesive from interfering with the operation of the circuit. A contact pad can be provided at a selected location and with a selected shape, and solder deposited on the pad, then reflowed to form the dam. The dam can be a structure soldered to a contact pad, or the dam can be supported at its ends by another structure of the device, so that, at the location where it functions to contain the adhesive, it is not attached to the substrate.
