Abstract:
A resonator/filter (100) adapted for direct surface mounting to the surface of a printed circuit board. The resonator/filter comprises a block of dielectric material (110) including at least one resonator through-hole (101-104) extending therethrough and respective top (112), bottom (113) and side surfaces (114-117) defining respective regions of dielectric material covered with conductive material. The top block surface defines at least a first conductive region. A second conductive region on the bottom surface of the block defines an input/output contact which allows the filter to be mounted on the board with the bottom filter surface seated thereon, thus providing a direct ground contact between the board and the resonator through-hole for improved attenuation performance particularly at higher frequencies. A plurality of transmission line embodiments (131, 156) electrically interconnect the first and second conductive regions.
Abstract:
The invention relates to an interconnection interface (1) which can be used to create at least one additional interconnection surface level for the production of three-dimensional electronic assemblies. According to the invention, the base boxes (3), which provide the electric interconnection with said interface, are surface assembly components of the type which have gullwing connections that extend out from the boxes called SO, TSOP, QFP, etc. Said interface consists of a one-piece printed circuit comprising at least two faces and having non-through openings and metallised through holes, thereby fulfilling the mechanical separator and electric connection functions simultaneously. The upper face (4) of the interface (1) is flat and forms a receiving and interconnecting circuit and the surface thereof, which is totally free, can be adapted to the size of additional components. The lower face of said interface comprises at least two levels, namely: a first level (5) forming a circuit which is used simultaneously for the electric interconnection and the mechanical bearing on the supports (2) of the base box(es) (3) and the link via metallised holes (6) with the upper face (4); and a second level (7) forming the apex of an opening that is used for the passage of the body/bodies of the base box(es) to be avoided.

Abstract:
In printed circuit board fabrication, processing steps for components on one section of the board are sometimes incompatible with processing steps for components on another section of the board. The method of the invention provides for physically separate printed circuit board sections that are processed separately and joined together following processing. To provide electrical connection between a first component on a first printed circuit board section and a second component on a second printed circuit board section, the method of the invention includes the steps of connecting the first and second components to conducting regions disposed on edges of their respective printed circuit board sections. The two printed circuit board sections are then joined together so that the two conducting regions contact each other.
