    Abstract: A ribbon cable includes electrical conductors surrounded by an insulator and vent tubes positioned adjacent and parallel to the conductors and insulator. The vent tubes allow airflow between an internal area of the enclosure and an external atmosphere and prevent access to the internal area of the enclosure.

    Abstract: A semiconductor chip package having a non-planar chip therein, to reduce the stress concentrations between the chip and cover plate. In particular, a chip and method of forming a chip having a non-planar or "domed" back surface, wherein the thickness of the non-planar chip is greatest substantially near the center of the chip. Further, a method of rounding the edges or corners of the chip to reduce crack propagation originating at the edges of the chip.

    Abstract: An electronic package 50 has an electronic component 58 with a first surface 59 electrically mounted to a substrate 54 and a second arcuate surface 64 with a contour such that the distance between the first surface and the second arcuate surface is greatest substantially near the centre of the electronic component. A method of forming a electronic package comprises providing an electronic component 58 with a first featured surface 59 and a second surface 64, and removing a portion of the second surface 64 so that the second surface 64 is substantially arcuate, with a thickness greatest substantially near the centre of the electronic component. A cap, cover plate, or heat sink 62, maybe mounted on a carrier 52 and the chip 58 by an adhesive 66. In alternative method of forming a chip, an electronic component is provided with a first featured surface and a second planar surface, a first portion of the second planar surface is removed to form a first arcuate surface and the second portion of the second planar surface is removed to form a second arcuate surface. A method of forming an electronic package having at least one profiled edge is also disclosed. A concave profiling tool 120 may be used to grind the shape of the chip.
