Abstract:
The present invention relates to a process for metallizing features of an electronic component, where the metallized features, conductive pads, conductive traces, are coated and encapsulated with at least one metal layer and the features on the front side and the back side of the component have different thicknesses. The process comprises the steps of: a) providing an organic based substrate having a conductive metal layer on a front and back side thereof; b) protecting the back side of the substrate, metallizing the front side wherein said metallizing is conducted by electroplating while electrically bussing the front side with the back side; and c) unprotecting the back side and protecting the front side and metallizing the back side by at least one of electroless plating or immersion plating.

The proposal is for an electrical device with an arrangement of printed circuit boards having at least one metal base plate (1) to which is laminated at least one printed circuit board (2) as a substrate. In order to obtain a compact structure with a versatile base plate (1), contact tongues (6), cooling components (11) and electrical connections (9) can be shaped from said base plate (1).
Abstract:
A measuring probe (30) has an analysis substrate support (A) with a woven fabric (1) consisting of metal warp threads (1a) and insulating plastic weft threads (1b) in the woof direction. Some of the mesh apertures are doped with analysis substrates (32-34) which change their electrical resistance on contact with, for example, a liquid to be measured. The metal threads (1a) passing the doped meshes constitute the electrical connection to the outside or to an evaluation circuit (B) which is preferably an integrated circuit.
Abstract:
A multilayer through-hole contacted flexible circuit and method of manufacture thereof is presented. The flexible circuit is made by providing through-holes (58) to a standard single sided laminate (50). Conductive material (60) is vacuum deposited into the through-holes and at the same time a conductive seed-layer is deposited on the polymer side of the standard laminate. Plating resist (62) is applied to both sides of the material and the seed-layer side of the material is patterned such that circuit traces, pads, and through-holes can be electroplated with additional copper (64). The plating resist (62) is stripped and the very thin layer of copper in the non-conductive areas is flash etched to produce semi-additive circuit features on the seed-layer side. Etch resist is then applied to both sides of the material and circuit patterns fabricated on the foil-side of the material. A cover film (66) and (68) coated with adhesive (70) and (72) is then provided over the exposed circuit patterns.
