Abstract:
Methods of making a copper interconnect plated through hole assembly are disclosed. Nano copper ink dispersed in an organic solvent is able to be filled in the plated through hole and forming the copper interconnect by sintering at a temperature below the melting of the copper.
Abstract:
An electronics assembly includes one or more electronic components coupled to a fabric. Each electronic component includes one or more electrical connection points, such as a bond pad or solder bump. The electronics assembly also includes one or more metal foils, one metal foil coupled to one electrical connection point on an electronic component. The metal foil is stitched to the fabric by an electrically conductive wire, thereby providing an electrical connection between the electronic component and the electrically conductive wire via the metal foil.
Abstract:
Methods of and Devices for quality control that can be used with automated optical inspection (AOI), solder paste inspection (SPI), and automated x-ray inspection (AXI) are disclosed. Plurality of threshold settings are entered in a testing process. Multiple testing results are obtained from the testing process. A graphic presentation is generated showing the numerical relationship among the data points, such that a quality control person is able to fine-tune the testing process to have a predetermined ratio of Defect Escaped % to False Call ppm.
Abstract:
A glue thickness inspection system automates a thickness measurement functionality for determining the thickness of both non-transparent and transparent materials including, but not limited to, glue, gel, solder and epoxy. The glue thickness inspection system includes a laser detector, a movable platform for positioning a unit under test, and a controller for controlling movement of the platform, angle of the laser detector, and calculation of the transparent material thickness. The laser detector includes a laser for emitting a laser light onto the unit under test and a sensor for receiving corresponding reflected light. The sensed data is used by the controller to determine the transparent material thickness.
Abstract:
A wearable electronics assembly includes one or more electronic modules coupled to a wearable electronics fabric. Each of the one or more electronic modules includes one or more plated through holes, through each of which is coupled an electrically conductive wire. The electrically conductive wire is stitched through the plated through hole and to a fabric onto which the electronic module is attached. The electronic module can include one or more electronic components coupled to a printed circuit board.
Abstract:
An RFID device assembly is fabricated by stitching an electrically conductive wire into a fabric as a pattern that forms an antenna. The two ends of the electrically conductive wire are positioned for coupling to antenna contact pads on an RFID device. The RFID device is attached to the fabric either before or after the electrically conductive wire is stitched to the fabric.
