A stretchable battery and the method of manufacturing the same. The stretchable battery can be manufactured by using a printing process. The construction of the stretchable battery can comprise a first layer of an elastomer film, a first current collector layer, a layer of cathode, a separating layer, a layer of anode, and a second current collector layer. Metal traces can be used to couple with the first and/or the second current collector layers.
Abstract:
An electronics assembly includes multiple electronic components coupled to a fabric. Each of the multiple electronic components includes one or more electrical connection points, such as a bond pad or solder bump. The electronics assembly also includes one or more electrically conductive wire braids, one electrically conductive wire braid coupled to one electrical connection point on an electronic component. One of the electrically conductive wire braids interconnects two electronic components, thereby providing an electrical connection between the two electronic components. The electrically conductive wire braid can be attached to the fabric by an adhesive, a stitched thread, which can be either electrically insulated or electrically conductive, or both adhesive and stitched thread. The fabric can be a wearable fabric, such as a shirt or pants, or other form to be worn by a user, such as an armband, waistband, hat or shoes.
Abstract:
A formed graphite sheet is shaped and sized as a protective shield positioned over an electronic component coupled to a PCB. The formed graphite sheet is used to protect a body of the electronic component from heat applied during the assembly of the electronic component to the PCB, such as the heating steps used in SMT and through-hole technology.
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 metal foils, each metal foil electrically coupled at one end to an electrical connection point of the electrical module and at another end to an electrically conductive wire. The electrically conductive wire is stitched to the metal foil 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. The metal foils can be formed from interconnects on the printed circuit board or the metal foils can be separate elements coupled to the printed circuit board.
Abstract:
An electronic module assembly and method of assembling an electronic module to a conductive fabric are provided. An electronic module assembly comprises a non-conductive fabric and a conductive fabric covering at least part of a first side of the non-conductive fabric. An electronics module is disposed on the conductive fabric, and a portion of the electronics module includes a wall defining a through hole. A fastener passing through the through hole and passing through the conductive fabric is configured to electronically couple the electronics module to the conductive fabric.
Abstract:
A method and apparatus for forming a conductor on an uneven two-dimensional (2-D) or three-dimensional (3-D) surface is described. An amount of conductive material needed to form a conductor between two points on a surface of an object is determined. The determined amount of conductive material is deposited on a substrate. The substrate with the deposited conductive material is applied to the object to form a conductor between the two points on the surface of the object. The conductive material and substrate may be stretchable. The conductive material may be deposited by an inkjet printer or an embedded 3-D printer. The substrate with the deposited conductive material may be applied to the object by laminating the substrate with the deposited conductive material to the object.

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.

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.
