Abstract:
The invention concerns a method and a device for connecting two millimetric elements. The method consists in producing in predetermined sites of each of the millimetric elements (13, 16) connecting zones (8) linked to a ground plane potential; then in carrying out the connection by predetermined links (17) between the connection zones (8) and between the conducting lines (6, 15) of the two millimetric elements (13, 16). The device consists in a coplanar line (17). The invention is particularly applicable to millimetric circuits using micro-strip conducting lines.
Abstract:
Power may be supplied to an electronic module according to various techniques. In one general implementation, for example, a system for supplying power to an electronic module may include a printed circuit board, the electronic module, and a conductive foil. The board may include a number of contact locations on a first side, with at least one of the contact locations electrically coupled to a via to a second side of the board. The electronic module may be electrically coupled to the contact locations on the first side of the board and receive electrical power through the at least one contact location electrically coupled to a via. The foil may be adapted to convey electrical power for the electronic module and electrically coupled on the second side of circuit board to at least the via electrically coupled to a contact location that receives electrical power for the electronic module.
Abstract:
An electronic device having a circuit board and a battery is disclosed. The circuit board may include a through hole and an electrical pad surrounding the through hole. In order to electrically couple the circuit board to the battery, and in particular, an electrode of the battery, a tab (or plaque) is placed between the electrical pad and the electrode. The tab electrically couples with the electrical pad by a soldering operation. To couple (electrically and mechanically) the tab with the electrode, a welding operation is used. The welding operation may include a laser weld providing thermal energy through a laser beam. In this regard, the laser beam passes through the through hole, thereby (partially) melting the tab and forming a weld between the tab and the electrode. Accordingly, the tab covers the through hole such that the tab is positioned to receive the laser beam.
