Multilayer dielectric structures particularly suitable for use in capacitors and having a plating dopant in an amount sufficient to promote plating of a conductive layer are provided, together with methods of forming such structures. Such dielectric structures show increased adhesion of subsequently applied conductive layers.
Abstract:
A composite material and a method for making same are disclosed. A composite article including an electrically and/or thermally insulating substrate and protective layers on each side thereof is particularly disclosed. Said material includes protective layers consisting of fibres of a heat-stable material flocked onto the insulating substrate, and a heat-stable coating resin. The resulting protective layer has improved protective properties, particularly moisture-proofness. The composite material may also be used as a metal layer carrier for forming flexible printed electrical circuits.
Abstract:
@ L'invention se rapporte à des substrats métallisables par traitement de réduction éventuellement suivi d'une métallisation par voie électrolytique, destinés à la réalisation de circuits imprimés. Les substrats comprennent une âme centrale constituée essentiellement de matière fibreuse cellulosique et/ou de paillettes de mica et d'une résine thermodurcissable renfermant éventuellement une charge inerte, et sur une ou deux de ses faces d'au moins une couche obtenue à partir d'une composition de résine thermodurcissable chargée par un oxyde métallique non conducteur dont le degré d'oxydation est choisi de manière à permettre une réduction facile par un borohydrure et qui est susceptible de former intermédiairement des hydrures métalliques instables. L'invention se rapporte à un procédé d'obtention desdits substrats par «voie papetière».
Abstract:
The invention relates to a method for sealing and/or electrically connecting components for a motor vehicle, having the steps of providing a first element (10) and a second element (20) which is arranged in a recess (14) of the first element (10); introducing electrically conductive additives into the first element (10) in the region of a boundary surface (5) which is formed as a transition between the first and the second element (10, 20); exposing the boundary surface (5) of the first element (10) and the second element (20); and chemically depositing a provided material and thereby forming a sealing layer and/or electrically conductive connection layer (3) on the first element (10) and the second element (20), thus sealing the boundary surface (5) and/or electric connection between the first element (10) and the second element (20).

Abstract:
A method of treating a laser-activated thermoplastic substrate having a metal compound dispersed therein is described. The substrate is contacted with an aqueous composition comprising: (i) a thiol functional organic compound; (ii) an ethoxylated alcohol surfactant; and (iii) xanthan gum. By use of the treatment composition, when the substrate is subsequently laser-activated and plated by electroless plating, extraneous plating of the substrate is substantially eliminated.
