Abstract:
This disclosure provides a technique that prevents debonding at an interface between a functional device and a resin on reflow soldering in a functional device-mounted module requiring a hollow structure. Also disclosed is a functional device having a functional portion mounted on a substrate formed with predetermined wiring patterns, wherein the functional portion of the functional device is arranged in a receiving space, and the substrate is provided with a hole which communicates with the receiving space and a solder-introducing portion made of a metallic material compatible with solder. During solder reflowing, the functional device-mounted module is placed on a mounting substrate such that the solder-introducing portion of the functional device-mounted module contacts a solder paste, and solder is melted with heat. Water inside the receiving space is thus discharged, and solder is introduced into the hole due to surface tension, and the interior of the receiving space is sealed.
Abstract:
A packaging method, a packaging structure and a package is substrate capable of restraining a warp of a thin film substrate, increasing a product yield, and building up a sufficient cooling capacity in the case of mounting an LSI having a high exothermic quantity.

Abstract:
A shielding apparatus for EMI-sensitive electronic components, especially for radio transmitting devices and/or radio receiving devices of telecommunication terminals for contactless telecommunication, such as cordless telephones and mobile telephones and similar, which can be constructed without using expensive manufacturing and assembly steps without any extra space requirement. The EMI-sensitive electronic components and/or circuits are arranged on a separate, at least double-layered printed circuit board and are embodied as a printed circuit board module. Said circuit board and another separate, at least two-layered circuit board which includes a recess for the EMI-sensitive electronic components and/or circuits and which is embodied in the form of a base printed circuit board, are joined together by soldering, preferably in the region of contact areas, to form a unit such that a cage is formed by the recess which is disposed between two metal surfaces being respectively connected to the shielding surfaces by means of continuous, highly adjacent contacts. The cage shields the EMI-sensitive electronic components and/or circuits on all sides.

Abstract:
The invention is an optical reader having a plurality of image sensors. Each image sensor of a plural image sensor optical reader can be disposed on an imaging module that can include a light source. In one embodiment, a frame of image data captured via actuation of an image sensor of a first imaging module and actuation of illumination of a second imaging module is subjected to decoding. The various modules of a multiple imaging module reader can be adapted to have different best focus positions so that a field depth of the reader is improved.
Abstract:
A stack package for a high density memory module includes at least one memory chip, an ASIC and an interposer, wherein the interposer comprises a first surface having contacts arranged in electrical communication with corresponding contacts on the ASIC and a second, substantially opposite surface including contacts arranged in electrical communication with corresponding contacts on a PCB. The at least one memory chip is dimensioned to fit within a cutout section in the interposer.
Abstract:
Systems and methods for reducing switching noise in an integrated circuit. In one embodiment, decoupling capacitors are connected to the integrated circuit from the underside of the substrate on which the integrated circuit die is manufactured. The decoupling capacitors are positioned with a higher concentration in the “hot spot” areas of the integrated circuit instead of being evenly distributed. In one embodiment, the decoupling capacitors and the corresponding hole(s) in a circuit board on which the integrated circuit is mounted are positioned so that the circuit board provides support for the central portion of the integrated circuit and thereby prevents the integrated circuit from flexing away from the heat sink/spreader. In one embodiment, the concentration of vias connecting the different ground planes and/or power planes within the integrated circuit is higher in hot spots than in other areas.
