Rogers Arlon CuClad 217 PTFE/Woven Fiberglass Laminate Microwave Printed Circuit Board Substrate
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: CuClad 217 uses a low fiberglass/PTFE ratio to provide the lowest dielectric constant and dissipation factor available in fiberglass reinforced PTFE based laminates. Together, these properties offer faster signal propagation and higher signal/noise ratios.
  • Cross Plied Woven Fiberglass, alternating plies are oriented 90° to each other
  • High PTFE to Glass Ratio
  • Better dielectric constant uniformity than comparable non-woven fiberglass reinforced laminates

Benefits:

  • Electrical and Mechanical isotropy in the X-Y Plane
  • Extremely Low Loss
  • Well Suited for Er Sensitive Circuits

Typical Applications:

  • Military Electronics (Radars, ECM, ESM)
  • Microwave Components (Filters, Couplers, LNAs, etc.)

Information provided by Arlon Materials for Electronics (MED); now a part of Rogers Corporation.

Vendors: Arlon Materials for Electronics (MED) is a major manufacturer of specialty high performance laminate and prepreg materials for use in a wide variety of printed circuit board (PCB) applications and in several distinctive markets.
