ABSTRACT:
A method for producing a layer of a multi-layer electronic circuit package and resulting article of manufacture is provided comprising the steps of selecting a core material from one of three iron
ickel alloys, namely either (i) 58% Fe/42% Ni; (ii) 60% Fe/39% Ni/1% Cu; or (iii) 60% Fe/38.7% Ni/0.12% Mn/0.07% Si; forming the core material into a panel suitable for an intended application; cleaning the panel in preparation for plating; plating the panel with copper; subjecting the plated panel to heat treatment; and circuitizing the panel as appropriate for the intended application.
