Abstract:
PROBLEM TO BE SOLVED: To provide a circuit substrate that allows accurately matching the impedance between an antenna coil and an electronic component electrically connected to the antenna coil.SOLUTION: A circuit substrate includes: a first substrate portion and a second substrate portion composed of an insulator layer of a flexible material; an antenna coil constituted from a coil conductor provided on the insulator layer in the first substrate portion; a wiring conductor provided on the insulator layer in the second substrate portion and electrically connected to the antenna coil; and a magnetic material layer. The first substrate portion and the second substrate portion are arranged so as to have opposite portions to each other. The magnetic material layer is provided in the first substrate portion, and is arranged between the coil conductor of the first substrate portion and the wiring conductor of the second substrate portion.
Abstract:
A display device (10) is provided with: a backlight chassis (36) having an aperture (43) which is contacted by an edge of a source substrate (41) when the source substrate (41) is displaced; and a source substrate (41) having a circuit pattern formed on the substrate rear surface (41a), which is the side facing the backlight chassis (36), and having a part thereof held by the backlight chassis (36).

Provided is an electronic component including a pad region including a plurality of pads extending along corresponding extension lines and arranged in a first direction, and a signal wire configured to receive a driving signal from the pad region, wherein the plurality of pads include a plurality of first pads arranged continuously and a plurality of second pads arranged continuously, and extension lines of the plurality of first pads substantially converge into a first point and extension lines of the plurality of second pads substantially converge into a second point different from the first point.
Abstract:
A flexible printed circuit board, in particular for connecting electrical and/or electronic components, includes a fuse conductor track (10). The fuse conductor track has a conductor width (B1) formed on the flexible printed circuit board (1). The fuse conductor track (10) has a taper (12) in a fuse area (11) of the fuse conductor track (10), at which the fuse conductor track (10) has a fuse width (B2) which is smaller than the conductor width (B1) of the fuse conductor track (10) outside the fuse area (11).
