摘要： A detachable fiber optic connector has an improved nose block (800) which enhances cooling of power dissipating components, simplifies assembly, improves yield and reduces cost. The improved nose block (800) includes an upper tray (802) and lower tray (804) which slidingly receive an improved aluminum nitride optical subassembly (700). The subassembly (700) and nose block (800) are held together, properly aligned, and then fixated. The nose block (800) also has symmetrical protrusions (850) which allow the nose block (800) to be placed easily and precisely into mating protrusions (230, 240) in a seal ring (200). The nose block (800) provides a direct thermal pathway between power dissipating components, such as an opto-electronic component (750) and optical driver IC (730), and an aluminum package base (400). Various alternative nose blocks (810, 820, 830) are illustrated, and an alternative base (410) is also shown. The package is completely sealed to ensure field reliability, and manufactured using low cost processes.
摘要翻译：可拆卸光纤连接器具有改进的鼻梁（800），其增强了功率耗散部件的冷却，简化组装，提高产量并降低成本。改进的鼻块（800）包括滑动地接收改进的氮化铝光学子组件（700）的上托盘（802）和下托盘（804）。子组件（700）和鼻块（800）保持在一起，适当对准，然后固定。鼻块（800）还具有对称的突起（850），其允许鼻塞（800）容易且准确地放置在密封环（200）中的配合突起（230,240）中。鼻梁（800）在诸如光电子部件（750）和光学驱动器IC（730）的功率耗散部件和铝包装基座（400）之间提供直接热路径。示出了各种替代的鼻子块（810,820,830），并且还示出了替代基座（410）。该封装完全密封，以确保现场可靠性，并使用低成本工艺制造。

摘要： A detachable fiber optic connector provides connection from an optical source or sink through a hermetic connection to a removable attached optical fiber. Ferrules and a split ring are used for alignment. A variety of alternative embodiments are illustrated for providing coupling force between the ferrules and retaining forces to prevent movement of the connection during movement of the fiber relative to the optical source or sink. These detachable fiber optic connectors provide great benefit when combined with hermetic packaging.

摘要： In forming an interconnection between a component and an electronic circuit, a base with precise component pockets is loaded with components. The components are patterned with a thin layer of solder paste. Next, a frame including a stencil, vertical walls and locating or keying features is placed onto the base. The stencil rests a controlled distance above the components. A multitude of solder spheres are dispensed into the frame. Solder balls retained within the frame are passed through the stencil and into contact with solder paste. Most preferably, due to controlled spacing between the stencil and components, only one solder ball is able to pass through each stencil hole. The remaining solder spheres in the frame are collected through various alternative techniques, including a disclosed emptying gate. Then the frame with stencil is removed from the base. The solder paste and solder spheres are heated, resulting in a reflow of the solder paste and a bonding of the solder spheres to the component. Subsequent processing may also include further reflowing of the solder spheres, cleaning of any residue from the components, and device testing, as appropriate.

摘要： An image sensor may be constructed as an imager die onto which is adhered an optical spacer. The imager die and optical spacer may be supported by a dam-and-fill construction which allows light to pass through the optical spacer and onto the imager die. The image sensor may generate control signals for use in a variety of automatic vehicle equipment controls and may be incorporated into an automotive vehicle such as by inclusion into a rearview mirror assembly.
