    Abstract: In some embodiments, an apparatus includes a printed circuit board and a thermal interface member. The printed circuit board is configured to be coupled to an electronic device, such as, for example, a removable (or “pluggable”) optical transceiver. A first surface of the printed circuit board includes a thermally-conductive portion, and a second surface of the printed circuit board includes a thermally-conductive portion that is coupled to the thermally-conductive portion of the first surface by a thermally-conductive via between the first surface and the second surface. The thermal interface member is coupled to the first surface of the printed circuit board such that a portion of the thermal interface member is in contact with the thermally-conductive portion of the first surface. The portion of thermal interface member is deformable and thermally-conductive.

    Abstract: The invention relates to a high-voltage insulation circuit board which is used in an electric power apparatus such as an electric power converter or the like such as power semiconductor device, inverter module, or the like and provides an insulation circuit board in which electric field concentration at the end sections of a wiring pattern is reduced, partial discharging is suppressed, and a reliability is high. According to the invention, there is provided an insulation circuit board having: a metal base substrate; and wiring patterns which are formed onto at least one of the surfaces of the metal base substrate through an insulation layer, characterized in that between two adjacent wiring patterns in which an electric potential difference exists among the wiring patterns, at least one or more wiring patterns or conductors which are in contact with the insulation layer and have an electric potential in a range of the electric potential difference between the adjacent wiring patterns are arranged. According to the invention, the electric field concentration at the end sections of the wiring pattern to which a high voltage is applied is reduced and partial-discharge-resistant characteristics are improved.

    Abstract: The invention relates to a method of fabricating a flexible-rigid PCB which includes a flexible circuit substrate and a rigid circuit substrate. The flexible circuit substrate defines a rigid region and an exposed region and has a conductive pattern, such as conductive traces, formed on the exposed region. The method includes the steps of providing the flexible circuit substrate; printing a paste containing epoxy-silicone hybrid materials onto the conductive pattern; curing the paste; and building up the rigid circuit substrate on the rigid region of the flexible circuit substrate. Particularly, the paste having a specific composition is subjected to predetermined conditions of temperature and time in order to transform the paste into a peelable mask with heat resistance, chemical resistance and a contact angle greater than 20 degrees.
