Abstract:
Probe includes a transducer, a PCB having a pattern part contacting the transducer via face-to-face contact, and a bonding member bonding the transducer to the pattern part of the PCB. The bonding part of the PCB is provided with the pattern part to increase a bonding area of the bonding part and to allow the bonding member to contact not only a metal layer of the bonding part but also an electrical insulation part thereof, thereby improving a bonding force between the transducer and the PCB. As a result, the transducer can be reliably bonded to the PCB, so that performance of the transducer can be prevented from being deteriorated due to defective connection between the PCB and the transducer.

A flat cable includes a dielectric element assembly including a plurality of dielectric layers laminated on each other, a linear signal line provided in the dielectric element assembly, a first ground conductor provided on one side in a direction of lamination relative to the signal line and including a plurality of first openings arranged along the signal line, and a second ground conductor provided on the other side in the direction of lamination relative to the signal line and including a plurality of second openings arranged along the signal line. The first ground conductor is more distant from the signal line in the direction of lamination than is the second ground conductor. The first openings are larger than the second openings.
Abstract:
A chip-on-film package comprises a film substrate comprising upper and lower surfaces, and a side having a bending part. A first output interconnection formed on the upper surface of the film substrate extends from a semiconductor chip disposed on the upper surface toward the bending part. A second output interconnection includes an upper output interconnection formed on the upper surface of the film substrate, and a lower output interconnection formed on the lower surface and extending onto the bending part. An input interconnection includes an upper input interconnection formed on the upper surface of the film substrate and a lower input interconnection formed on the lower surface and extending away from the bending part. Through-vias are formed to pass through the film substrate and electrically connect the upper output interconnection to the lower output interconnection, and the upper input interconnection to the lower input interconnection.

Abstract:
A rigid flex circuit comprised of high thermal conductivity sections, said sections having components disposed so as to have their contacts substantially planar with the surface of the thermally conductive section and wherein the contacts are interconnected directly to the traces without the use of solder and further having the thermally conductive sections interconnected to one another by means of flexible circuit sections.
Abstract:
Systems and methods for the design and fabrication of flexible devices, including high-performance large-area OLEDs, narrow border display panels and lighting panels are provided. Various described fabrication- and design-processes may be used to provide the necessary electrical drive to lighting and display panels. Electrical drive may be provided to one or more row- and column-signals by patterning conductive elements near the panel edge. The electrical elements may further be folded over a region near the panel edge back on itself, such that electrical traces may route around the display edge. This may allow the display active area to be substantially the same area as its viewing area, and furthermore may allow pixels go substantially all the way to the edge of the viewing area.
Abstract:
A folded micro-wire substrate structure includes a transparent folded flexible substrate having a first side and a second side opposed to the first side. The flexible substrate has a first portion and a second portion adjacent to the first portion of the flexible substrate. The flexible substrate has at least a first fold between the first and second portions so that the first portion is aligned with the second portion in a perpendicular direction. One or more electrical conductors is located in or on the flexible substrate, at least one electrical component is located on or in the flexible substrate in the first portion. At least one optical element is located on or in the flexible substrate in the second portion located so that the optical element directs light to or from the electrical component.
