Abstract:
Um bei einer elektronischen Baugruppe (10) mit verschiedenen elektronischen Bauteilen (12, 18) auf einer Leiterplatte wenigstens partiellen Schutz gegenüber schädlichen Umwelteinflüssen herzustellen, wird vorgeschlagen, dass wenigstens ein zu schützendes Bauteil (18) mit einer Vergussmasse zu umschliessen, die wiederum von einem Vergussrahmen (20) umgeben ist.
Abstract:
An electrical device (100) comprising an electronic component (105) mounted to a surface (110) of a printed circuit board (115), a ground connection (120) on said surface, and electromagnetic interference (EMI) shielding (125). The EMI shielding includes an electrical insulator (130) coating the electronic component, the insulator contacting the surface, and a conductive layer (135) covering the electrical insulator, and contacting the electrical insulator and the ground connection.
Abstract:
A coating (203) for mitigating metal whiskers on a metal surface (202) includes a polymeric coating material; and a metal ion complexing agent impregnated within the polymeric coating material, the metal ion complexing agent having a standard reduction potential (E°) that is greater than a metal in the metal surface.
Abstract:
A frame is provided, for applying potting material to a printed circuit board (PCB). The frame includes a plurality of substantially vertically oriented walls arranged to isolate a surface of the PCB into a plurality of zones. This allows the frame to be aligned over the surface of the PCB to isolate the surface of the PCB into a plurality of zones, each zone comprising at least one PCB component; and allows the potting material to be applied into the zones to achieve coverage of the PCB components in that zone.
Abstract:
An isolator assembly is disclosed. The assembly comprises a laminate consisting essentially of a block of homogenous material and a set of electrical contacts. A first die is coupled to a surface of the laminate. An isolation barrier is located entirely above the surface of the laminate. A second die is coupled to the laminate. The second die is galvanically isolated from the first die by the isolation barrier. The second die is in operative communication with the first die via the isolation barrier and a conductive trace on the laminate. The first die, the second die, the laminate, and the isolation barrier are all contained within an assembly package.
Abstract:
A conductor pad (102-1,..., 102-n) and a flexible circuit (100) including a conductor pad are provided. The conductor pad includes a first contact region (125), a second contact region (130), and a body portion (110) configured to establish a conductive path between the first contact region and the second contact region. The body portion includes a perimeter edge having at least a first convex segment and a second convex with a first non-convex segment disposed between the first convex segment and the second convex segment. A method of constructing a flexible circuit to facilitate roll-to-roll manufacturing of the flexible circuit is also provided.
