Abstract:
High-speed interconnects for printed circuit boards and methods for forming the high-speed interconnects are described. A high-speed interconnect may comprise a region of a conductive film having a reduced surface roughness and one or more regions that have been treated for improved bonding with an adjacent insulating layer. Regions of reduced roughness may be used to carry high data rate signals within PCBs. Regions treated for bonding may include a roughened surface, adhesion-promoting chemical treatment, and/or material deposited to improve wettability of the surface and/or adhesion to a cured insulator.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines umgeformten Schaltungsträgers in Form eines Laminats aus Haftvermittlerfolie (1), ggf. Kleberschicht (2), Schaltungsträgerfolie (3) und rein metallischer Leiterbahn (4), letztere mit einer bevorzugten Dickenabmessung in der Größenordnung von 1000 Atomlagen. Ferner betrifft die Erfindung einen umgeformten Schaltung sträger (1-4). Bei dem erfindungsgemäßen Verfahren wird der Schaltungsträger (1-4) umgeformt mittels eines gasförmigen Druckmittels, wobei das Umformen oberhalb der Glastemperatur und unterhalb der Schmelztemperatur der umzuformenden Schaltungsträgerfolie (3) unter hohem Gasdruck schlagartig erfolgt. Dank der Erfindung lassen sich erstmals stark umgeformte, insbesondere frei oder sphärisch geformte Schaltungsträger auch mit rein metallischen Leiterbahnen erzeugen. Durch optionale Hinter spritz ung (9), Aufbringung von Dekorlagen (1 1) und/oder Überzugsschichten (10) lassen sich multifunktionale, nahtlos freigeformte Kunststoffbauteile mit Elektronikintegration erhalten.
Abstract:
The present invention relates to: a composition for forming a conductive pattern, capable of allowing a conductive micropattern to be formed on various polymer resin products or resin layers by a simplified process and providing remarkable flame retardancy to the resin products or the resin layers; and a resin structure having a conductive pattern obtained by using the same. The composition for forming a conductive pattern comprises: a polymer resin; a nonconductive metal compound containing a first metal and a second metal and having a chemical formula (1) or P63/mmc space group structure; and a flame retardant. In addition, a metal nucleus containing the first metal or the second metal, or an ion thereof is formed from the nonconductive metal compound by the irradiation of electromagnetic waves.

The present invention provides an insulation film and a method for making the insulation film, comprising a film upper layer and a film lower layer, wherein both of the film upper layer and film lower layer are made of a heat conduction plastics material, the heat conduction plastics material contains a heat conduction additive; and a film intermediate layer located between the film upper layer and the film lower layer. The film intermediate layer is made of a heat conduction plastics material, and the heat conduction plastics material contains a conductive additive An upper surface of the film intermediate layer is bound together with a lower surface of the film upper layer, and a lower surface of the film intermediate layer is bound together with an upper surface of the film lower layer.
Abstract:
Techniques are disclosed for attaching SMDs to a flexible substrate using conductive epoxy bond pads. Each bond pad includes a set of elongated strips of conductive epoxy that are applied and cured onto the flexible substrate in an adjacent and parallel fashion. The bond pads are used to attach SMDs to the flexible substrate and also provide the conductive contacts for a printed circuit. A circuit may be printed on the flexible substrate using conductive ink that partially covers the bond pads, leaving a portion of the pads exposed. A second layer or strip of conductive epoxy may be applied over and across the exposed portions of the bond pad strips in order to attach an SMD. The number, size, and orientation of the epoxy bond pad strips may be determined by the amount of bending the flexible substrate is expected to withstand and/or the orientation of the bend.
Abstract:
Epidermal electronics are sensors with mechanical properties matching human epidermis. Their manufacturing process includes photolithography and dry and wet etching within cleanroom facilities. The high cost of manpower, materials, photo masks, and facilities greatly hinders the commercialization potential of disposable epidermal electronics. In contrast, an embodiment of the invention includes a low cost, high throughput, bench top "cut and paste" method to complete the freeform manufacture of epidermal sensor system (ESS) in minutes. This versatile method works for many types of thin metal and polymeric sheets and is compatible with many tattoo adhesives or medical tapes. The resultant ESS is highly multimaterial and multifunctional and may measure ECG, EMG, skin temperature, skin hydration, as well as respiratory rate. Also, a stretchable planar coil made of serpentine ribbons can be used as a wireless strain gauge and/or a near field communication (NFC) antenna. Other embodiments are described herein.
