L'INVENTION CONCERNE UN ELEMENT COMPOSITE COMPRENANT DU CUIVRE ET UNE MATIERE PLASTIQUE. ELLE SE RAPPORTE A UN STRATIFIE DE CUIVRE ET DE MATIERE PLASTIQUE AYANT UNE EXCELLENTE RESISTANCE DE LIAISON. LE CUIVRE DU STRATIFIE EST FORME DE CUIVRE OU D'UN ALLIAGE DE CUIVRE ET SA SURFACE A UN REVETEMENT DE PHOSPHATE DE CUIVRE QUI EST UNIFORME, VITREUX ET PRATIQUEMENT DEPOURVU DE PORES. LA MATIERE PLASTIQUE D'ENROBAGE, DE PREFERENCE UNE RESINE EPOXYDE CONTENANT UN AGENT DE DEMOULAGE, EST MOULEE SUR LE CUIVRE. APPLICATION A L'ENROBAGE DES DISPOSITIFS A SEMI-CONDUCTEURS MONTES SUR DES CADRES DE CONNEXION.

Element composite de cuivre et de matiere plastique et son procede de realisation

1,118,998 Making electric circuit modules MEL EQUIPMENT CO Ltd 2 May, 1967 [3 May, 1966], No 19432/66 Heading B3A [Also in Division H1] An electric circuit module is made by stamping a metal blank and securing electrical components 9, 10 in the stamped out portions The blank may be cut from a strip of " Monel " (Registered Trade Mark), brass or nickel silver either before or after stamping Reference marks 2 are made along each side of the blank which are sensed by a component supplying and positioning machine Notches 5 are provided in the cross-strips 7, 8 to permit easy removal from the end strip 4 and notches (5 1 ), Fig 1 (not shown), to accommodate the components The assembly is preferably encapsulated in epoxy resin with limb portions 11 acting as terminals The components may be resistances 9 and a transistor 10 arranged to form a NOR gate The electrical components secured in the blank may alternatively be secured in a box-like structure or held between two spaced surfaces instead of being moulded in epoxy resin
