Abstract
The invention concerns multilayered constructions useful for forming resistors and capacitors, for the manufacture of printed circuit boards or other microelectronic devices. The multilayered constructions comprise sequentially attached layers comprising: a first electrically conductive layer, a first thermosetting polymer layer, a heat resistant film layer, a second thermosetting polymer layer, and a nickel-phosphorus electrical resistance material layer electroplated onto a second electrically conductive layer.
