Definitions

  • Embedded passives comprise a type of Printed Circuit Board (PCB) design that combines better performance in smaller boards with increased functionality by burying resistors or capacitors, i.e. passive devices, in the substrate material itself.
  • PCB Printed Circuit Board
  • resistors or capacitors i.e. passive devices
  • important performance requirements for making PCBs having embedded resistors operating in the 100 Ohms to 1 mega-Ohm range include a balanced Temperature Coefficient of Resistance ["TCR”] and resistive stability.
  • new materials are required since current materials satisfy neither the performance nor fabrication requirements for0 routine manufacture of embedded passives in PCBs.
  • a group IV metal carbide or nitride is defined as a compound with the chemical formula A x B y where A pertains to any group IV metal and/or their mixtures, and B is C or N.

Abstract

La présente invention concerne des compositions contenant de 20 à 50 % en volume d'un nitrure ou carbure d'un métal du groupe IV, un polymère et de 1 à 9 % en volume d'une forme allotropique de carbone. Les compositions sont utiles dans la fabrication de résistors avec de faibles coefficients de résistivité thermique.
