Abstract:
A configuration of an electronics unit is disclosed wherein a plurality of circular circuit cards are arranged in an aligned, parallel relationship. Each card has a central circular inner opening formed therein. A plurality of inner and outer spacer elements support the respective inner and outer peripheries of the cards. The conductive patterns on the cards include a plurality of conductive pads arranged around the inner and outer peripheries of the cards. Circular metal-on-elastomer inner and outer connectors engage respective one of the inner and outer spacers, and the metal traces of the connectors make electrical contact with aligned conductive pads of adjacent cards. The unit includes a cover structure which envelopes the circuit card configuration to form a sealed unit, and an electrically insulating coolant liquid is disposed in the sealed unit in direct contact with the circuit cards and electrical components mounted thereon to absorb heat generated by electrical power dissipation. The electronics unit is particularly well suited to use with a guided vehicle configuration, such as a missile, wherein a tubular center structural member extends forwardly from the aft missile body, and the electronics unit is assembled with the tubular member extending through the central opening in the electronics unit. The sensor platform of the missile receives the tubular support member through a central opening. The sensor platform is secured by a fastener exerting compression forces along the central missile axis, thereby also aligning the sensor platform with the aft missile body containing the missile propulsion system.

The present invention provides a connection structure of conductors in which, when connecting a pair of conductors facing each other using an anisotropic conductive film containing conductive particles dispersed therein, a short circuit between the adjacent conductors due to a movement of conductive particles is be prevented, and a display apparatus having the connection structure of conductors. When executing thermo-compression bonding processing while interposing the anisotropic conductive film, even if conductive particles dispersed in the anisotropic conductive film are concentrated and continued in a gap between adjacent first terminals, in the vicinity of an edge of an interlayer insulation film, since a distance between the first terminals adjacent to each other is increased due to notches formed therein, the first terminals adjacent to each other are not short-circuited.
Abstract:
A stretchable circuit board has stretchability as well as flexibility of the flexible substrate and retains mechanical and electrical properties even under larger deformation such as bending, twisting, etc. The liquid metal pattern can exhibit stretchability almost to same to that of the polymer substrate due to that the liquid metal is fully wetted on the substrate with metal patterns based on the wetting behavior of the liquid metal. Therefore, the stretchable circuit board can achieve both mechanical and electrical properties even under physical deformation such as bending, stretching and twisting. It is demonstrated that the stretchable circuit board can be effectively applied to wearable tactile interfaces, stretchable solar cell arrays, stretchable displays, and wearable electronic devices.
