Pyralux® HT

Pyralux® HT high temperature polyimide bonding film


Pyralux® HT high temperature polyimide bonding film features a thermoplastic polyimide composition that is suitable for application either as a coverlay to protect surface circuitry or bond ply for multilayer flex and rigid-flex applications. This stand-alone film exhibits low loss characteristics for high performance applications. Pyralux® HT can be used in conjunction with all-polyimide Pyralux® clads to afford a robust circuitry solution for applications requiring high operating temperature performance, excellent signal integrity, and high reliability.

Features & Benefits

  • > 225 °C IPC service temperature when used as bond ply with Pyralux® AP double-sided copper-clad laminate
  • Low loss dielectric composition
  • Excellent thermal resistance from polyimide dielectric

Applications

  • High temperature flex and rigid flex circuits
  • Multilayer flex bond ply applications
  • Flex coverlay for surface circuit protection
  • Low loss, high signal integrity interconnects
  • High reliability all polyimide constructions
