Abstract:
The invention is a printed wire board laminate comprising resin layers reinforced with parallel, unidirectional fibres, the laminate having a thickness factor of below 5,5. The thickness factor is the ratio of the thickness of the substrate in µm and the average titer (linear density) of the yarn used (in tex). The laminates can be made using a method in which a high extent of filament spreading can be retained by virtue of at least partial curing of the UD-reinforced layers.
Abstract:
A method for the manufacture in a continuous process of a flat substrate from a fibres-reinforced matrix for a printed circuit, in which use is made of at least two moving layers of reinforcing fibres (5,11) and the fibres are positioned in at least two crossing directions, whereupon the filaments layers provided with matrix material, optionally together with one or more electrical conducting layers, such as a metal foil (20,21), and/or insulating layers on one or on either outer side, are passed through a preferably heated laminating zone, such as a double belt press (22,23), characterized in that use is made of filaments-containing layers made up of a plurality of mutually parallel filaments that are not bound in the form of a fabric and extend substantially linear.

Abstract:
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:
A package board includes a stack structure that includes a circuit layer and a fiber layer. The fiber layer includes at least one first fiber that extends in a first direction and is a non-woven fiber. Also, a prepreg includes a first fiber that is a non-woven fiber; a plurality of second fibers that are spaced apart from the first fiber and are woven fibers; and an insulating layer that fills gaps between the first fiber and the plurality of second fibers.
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 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.
