A wiring substrate includes an insulating layer, a conductor layer formed on a surface of the insulating layer such that the conductor layer includes a conductor pad, and a solder resist layer formed on the surface of the insulating layer such that the solder resist layer is covering the conductor layer and having an opening exposing the conductor pad. The conductor pad of the conductor layer has a substantially rectangular planar shape such that the conductor pads has a main surface, a pair of long sides, a pair of short sides and four corner portions, and the solder resist layer is formed such that the opening is exposing side surfaces at the long sides and 50% or more of the main surface and that the solder resist layer is covering side surfaces at the short sides.

A display apparatus, includes: a flexible circuit board including a first board pad and a second board pad, which are spaced apart from each other in a first direction and extend in a second direction intersecting the first direction; a main circuit board coupled to the flexible circuit board; and a display panel coupled to the flexible circuit board, the display panel including a first display pad overlapped with the first board pad and a second display pad overlapped with the second board pad, wherein the first board pad includes a first, second, and third portions, and the second board pad includes a first, second, and third portions.

A display device and a manufacturing method thereof are provided. The display device includes a display panel and a flexible circuit board electrically connected with the display panel. The flexible circuit board includes a first circuit board, a second circuit board and a conductive portion; the first circuit board includes a first substrate, and a main contact pad, a first wire and a second wire provided on the first substrate; the second circuit board includes a second substrate, a relay contact pad and a third wire provided on the second substrate; and the conductive portion is configured for electrically connecting the main contact pad and the relay contact pad.

A camera for a vehicle vision system includes a front housing portion, a circuit board, and a rear housing portion having a connector portion for connection of a vehicle coaxial cable. The circuit board includes a first solder pad for soldering a core pin connecting element, and a second solder pad that partially circumscribes the first solder pad for soldering a shielding connecting element. The second solder pad only partially circumscribes the first solder pad so as to have a gap between opposing ends of the second solder pad. The gap is configured to allow for escape of gases that evaporate out of the solder during the soldering process. The core pin connecting element electrically connects between a core pin of the connected coaxial cable and circuitry of the circuit board and the shielding connecting element electrically connects between shielding of the coaxial cable and circuitry of the circuit board.

An electrical contact pad for electrically contacting a connector includes a first region having a first length in a longitudinal direction, and a second region having a second length in the longitudinal direction that is greater than the first length. The first region is arranged to contact a first arm of the connector and the second region is arranged to contact a second arm of the connector. The first length being smaller than the second length results in an increase in the impedance of the electrical contact pad as compared to typical contact pads which tend to correspond to low impedance regions.
