  • Patent number: 11251160
    Abstract: Manufacturing of flip-chip type assemblies is provided, and includes forming one or more contact elements of electrically conductive material on a carrier surface of at least one chip carrier, providing a restrain structure around the contact elements, depositing solder material on the contact elements and/or on one or more terminals of electrically conductive material on a chip surface of at least one integrated circuit chip, and placing the chip with each terminal facing corresponding contact elements. Further, the method includes soldering each terminal to the corresponding contact element by a soldering material, the soldering material being restrained during a soldering of the terminals to the contact elements by the restrain structure, and forming one or more heat dissipation elements of thermally conductive material on the carrier surface for facing the chip surface displaced from the terminals, where the one or more heat dissipation elements are free of any solder mask.

  • Publication number: 20080069494
    Abstract: An electro-optical module comprising flexible connection cable and aligning capabilities is disclosed. Electro-optical devices may be soldered on a transparent substrate such as glass or a substrate comprising an optical waveguide wherein electrically conductive traces are designed, forming an electro-optical module. When such electro-optical module is inserted and aligned into a printed circuit board, the external part of the substrate, comprising electrically conductive traces and pads, referred to as flex-cable, is bent down toward the mounting plane of the PCB allowing to establish electrical connections between these pads and the PCB. The substrate may be broken along a pre-formed groove, and the external part of the substrate can be removed leaving the flex-cable section in place.

  • Publication number: 20080036598
    Abstract: A tamper-proof structure for protecting an electronic module, comprising a pattern of signal lines having a highly unpredictable layout, which is an approximation of a space-filling curve obtained by the replication of at least one elementary space element having an inscribed base curve inscribed therein. The base curve is adapted, by replication of the elementary space element, to generate an approximation of an at least two-dimensional space-filling curve, the replication being such that an end of the base curve in one elementary space element is connected to the end of the base curve in another, adjacent elementary space element of the replication.

  • Publication number: 20080011814
    Abstract: A method and system for efficiently self-aligning parts of a MEMS during manufacturing, as well as controlling distance between these parts, are disclosed. According to the invention each MEMS part comprises at least one pad that is aligned so as to form a pair of pads. In a preferred embodiment, each part comprises three pads. The pad shape of two pairs of pads is rectangular, one pair being rotated of an angle approximately equal to 90° from the other, and the pad shape of the third pair is annular. Therefore, one of the pair of pads allows alignment according to a first direction, a second pair of pads allows alignment according to a second direction, and the third pair of pads allows rotational alignment.
