Pyralux® APR all-polyimide embedded resistor laminate


Pyralux® APR all-polyimide embedded resistor laminate features an adhesiveless, all-polyimide dielectric layer in combination with TCR® thin-film embedded resistor copper foil from Ticer Technologies. This material system is ideal for multilayer flex, rigid-flex, and rigid printed circuit board (PCB) applications which require reliable embedded resistor technology, advanced material performance, temperature resistance, high reliability, and robust processing. Offered in a wide range of dielectric thicknesses and resistance levels.

Features & Benefits

  • Excellent resistive and dielectric layer tolerance and electrical performance
  • Embedded capacitance and resistance in a single laminate
  • Excellent bond strength affords high reliability
  • High thermal resistance to facilitate processing
  • Balanced and unbalanced constructions available

Applications

  • Multilayer flexible circuits and rigid-flex circuit constructions that require embedded resistor functionality
  • High reliability circuits that require stable dielectric performance
  • Space constrained designs benefiting from embedded passive integration
