    Abstract: A printed circuit board for electrical devices having RF components, particularly for mobile radio telecommunication devices, wherein to increase the packing density of electronic circuits and conductor-track structures on such circuit board, a “micro via” coating is initially applied to one or both sides of a printed circuit board assembly. This “micro via” coating then has, in particular, RF circuits and RF conductor-track structures applied to at least part of its surface. Finally, the RF circuits and RF conductor-track structures are protected in relation to an RF ground coating of the printed circuit board assembly by barrier areas arranged in an assembly coating, situated directly below the “micro via” coating, of the printed circuit board assembly against interfering influences which impair the RF parameters, to be set in each case, of the RF circuits and RF conductor-track structures.

    Abstract: A multilayer printed circuit board which reliably and economically marries conventional copper clad printed circuit board technology with polymeric conductors and insulators. Reliability is enhanced by forming all solder pads of copper, providing conductive tails on solder pads which are to be connected by polymeric inks, and ultimately forming a solder resist over all but the solder pads. As a result, polymer inks can be applied to both sides of the board, and the completed board can be subject to conventional solder dipping or wave soldering operations. According to one feature of the invention, a thin dielectric layer can be applied as intermediate to planar conductive layers which form a power plane having built-in distributed capacitance for decoupling.

    Abstract: Multilayer circuit boards having large area through-hole electrical connections are provided by a process that begins with the fabrication by known means of a drilled and through-hole plated single layer board. Next, a layer of insulating material is applied to either side of the board, leaving at least the through-hole plating exposed. A continuous layer of metal is then deposited on the body, completely covering the insulating layer and through-hole plating. Finally, the deposited metal layer is selectively masked and etched to form conductive circuit patterns on the insulating layer, overlying the original circuit patterns and electrically connected to them by the multiple layer through-hole plating.

    Abstract: PROBLEM TO BE SOLVED: To provide a printed board and a printed board unit by which a rise amount of a conductor can securely be detected. SOLUTION: A through hole 23 of a board 14 partitions a space by an insulator. The through hole 23 receives a lead terminal 28 of an electronic component 15. The lead terminal 28 is brought into contact with the conductor 29. The conductor 29 is exposed at least on the first face or the second face of the board 14. Conductor patterns 24, 25, 26 and 27 face the space in the through hole 23 from between arbitrary insulating layers 17. The conductor patterns 24, 25, 26 and 27 are connected to conductive materials 33, 34, 37 and 38 exposed at least in the first face or the second face of the board 14. The presence or absence of the establishment of conduction is detected between the lead terminal 28 and one of the conductive materials 33, 34, 37 and 38. When conduction is detected, it is confirmed that the conductor 29 is raised to positions of the conductive materials 33, 34, 37 and 38. The rise amount of the conductor 29 is securely detected.
