Abstract: According to an exemplary embodiment, a substrate having a first area and a second area is provided. The substrate includes a plurality of pads. Each of the pads has a pad size. The pad size in the first area is larger than the pad size in the second area.

Abstract: An electronic device is provided with a first connector module configured to mate with an external plug. The first connector module includes a first set of terminals; a first wafer supporting the first set of terminals, a first one or more of the second ends of the first set of terminals are bent to form a first set of tails, and a second one or more of the second ends of the first set of terminals terminate within the first wafer; and a tail alignment structure positioned to support the first set of tails. The electronic device further includes a cable arrangement forming a connection with the second one or more of the second ends of the first set of terminals; a host board configured to form an electrical connection with the first set of tails; and a shield assembly.

Abstract: A double-variable-curvature lensed fiber includes a cylindrical fiber body defining a central axis, and a lens body connected integrally to one end of the fiber body. The lens body has first and second inclined curved surfaces disposed respectively at opposite sides of an imaginary plane on which the central axis is disposed, and a light-transmissive portion formed between the first and second inclined curved surfaces. The light-transmissive portion has a first radius of curvature when viewed from a first direction, and a second radius of curvature when viewed from a second direction. The second radius of curvature is different from the first radius of curvature.

Abstract: A fiber grinding process includes: contacting an end of the optical fiber with a grinding surface in such a manner that a central axis of the optical fiber at the end is inclined to the grinding surface; rotating the optical fiber about the central axis; and changing a contact pressure between the end of the optical fiber and the grinding surface by applying a variable torque while rotating the optical fiber. A substantially cone-shaped end face with a substantially elliptic cross-section may be produced. A fiber grinding apparatus is also disclosed.
