Abstract:
The invention relates to a circuit board comprising at least one additional electrically conductive structure that is in the form of a round or rectangular electrically conductive wiring element, in particular in the form of an elongate copper element or element containing copper, that is brought into contact with copper film elements by ultrasound on at least one part on the surface on the copper film elements and is integrated into the circuit board by means of a lamination process. The at least one elongate wiring element has a cross-section that is deformed by means of a specifically formed sonotrode in a contact area that is flat in parts, such that the contact surfaces are at least 20%, in particular more than 30% and more particularly more than 50% greater in a non-deformed contact surface. The wiring element is further deformed in the cross-section in an approximately triangular like manner or in a trapezoidal manner thus increasing the contact surface. Also, the elongate wiring element in brought into contact at defined intervals in a flat manner on a conductive film element that is arranged therebelow.
Abstract:
The present invention relates to mounting an electric connector (20) onto a printed circuit board, particularly to a printed circuit board comprised of ceramic material, for instance either an LTCC substrate or an HTCC substrate. The problem addressed is one where the connector (20) tends to loosen from the substrate when the temperature varies. This is due to the difference in the coefficients of thermal expansion of the printed circuit board and the connector (20). The problem is solved with the aid of a so-called shim (10) that has a coefficient of thermal expansion between that of the printed circuit board and that of the connector. One side of the shim (10) is soldered onto the connector and the other side of the shim is soldered onto the printed circuit board. The connector (20) is therewith fastened to the printed circuit board. Shear stresses acting between the connector (20) and the printed circuit board are distributed through said board through the medium of two joints instead of one. The connector may alternatively be provided with a built-in shim.
Abstract:
There are disclosed printed board (5) on which electronic parts are mounted, a method for manufacturing the printed board, and a structure for connecting conductor elements (8, 8') to this printed board. The printed board includes an insulating supporting substrate (50) and at least one metallic terminal (53, 54). The supporting substrate is provided with at least one opening (51, 52) through the substrate, and the metallic terminal is fixed to the supporting substrate without protruding from the supporting substrate and bridges the opening.
Abstract:
Electric connections assembled in a connection or contacting element may be produced in high number and with a high density, preferably by a process from the thin film technology. The increasing 3D-integration of microelectronic structures requires a high number of vertical electric connections in the smallest possible space and with a good signal transmission quality, in particular for contacts through microelectronic substrates. For that purpose, prefabricated miniaturised contacting elements which provide the required high number of vertical electric connections are embedded in the most different substrate materials. The invention allows vertical electric connections to achieve the high quality of usual horizontal printed circuits. The contacting elements are embedded in the substrate materials by a planar junction technique which is a simple packaging technique that may be carried out even by small enterprises.
Abstract:
A flexibly configurable power distribution center (30) in which an electrical signal or power is routed by implementing an electrical interconnection at any point along a path of a conductor. Insulative portions (34, 35) or boards within an electrical power distribution center are fabricated having a plurality of recesses in the insulating portions. The strips of metal (66) are dimensioned and disposed within the recesses (64) for receiving electrical conductors therein. The electrical conductors (66) are in the form of flexibly configurable strips of metal such as steel, copper, brass or the like, which are disposed within the recesses in the insulating portions. The strips of metal (66) are dimensioned and disposed within the recesses (64), forming an exposed conductive ridge which is mechanically and electrically engageable by interface terminals along substantially the entire length of the conductor. The interface terminals (72, 72') have at least one female mating portion (74) for mechanically mating with the conductive ridge to establish electrical continuity therewith.
Abstract:
A microstrip line capable of feeding a large DC current, in spite of maintaining a high characteristic impedance. The microstrip line is provided with a dielectric base (10), an earthing conductor (12), a conductor strip (14), and an upper conductor part (16). The upper conductor part (16) is provided nearly on the central line of the conductor strip (14), and has a section which is thick in a vertical direction and whose width w1 of the lower base (16a) is narrower than the width W of the conductor strip (14) and respective width w2 from the base (16a) to its opposite side (16b) are nearly equal to the width w1 of the base (16a) or become larger than the width w1 at upper parts. The upper conductor part (16) of such sectional shape is formed by welding onto the conductor strip (14) a linear member made of gold, silver or copper whose section is shaped so through etching, or by depositing on the conductor strip (14) gold, silver or copper through plating.
