Pyralux® TA & TAH Copper-Clad Laminate

Pyralux® TA & TAH Copper-Clad Laminate

Pyralux® TA and TAH are Double-sided Copper-clad Laminates featuring adhesive-less, all-polyimide dielectric layers. These materials exhibit excellent low loss performance, enabling remarkable signal integrity in high-speed digital and highfrequency circuit applications. Offered in a variety of both dielectric and conductor thickness, Pyralux® TA and TAH provide designers, fabricators, and assemblers a versatile option for a wide variety of flexible circuit constructions.

Special Warnings
  • Should be stored in original packaging at temperatures of 4 - 29 °C (40 - 85 °F) and below 70% relative humidity. The product should not be frozen and should be kept dry, clean, and well-protected.
  • Subject to compliance with the foregoing handling and storage recommendations, Qnity’s warranties shall remain in effect for the period provided in the Qnity Standard Conditions of Sale.
Recommendations
  • Prior to handling, Qnity recommends referencing the Pyralux® Safe Handling Guide available at pyralux.dupont.com.

Features & benefits

  • Compatible with conventional flexible circuit fabrication processes, including oxide treatment and wet chemical plated-through-hole desmearing
  • Excellent static bending repeatability and mechanical performance
  • Excellent thermal resistance from all-polyimide dielectric
  • Fabricated circuits can be cover coated and laminated together to form multilayers or bonded to heat sinks using polyimide, acrylic, or epoxy adhesives.
  • High flex and bending reliability due to excellent adhesion between dielectric and copper foil
  • Low loss dielectric and ED Cu foil (TA) or RA Cu foil (TAH) conductor layers
  • Minimal variance in dielectric thickness for consistent circuitry performance
  • Pyralux® TA can pass 350oC solder floating test (10sec * 3 times), and is compatible with hot bar process
  • RoHS Compliant
  • Same process as processing standard PI based FCCL
  • UL 94 VTM-0, UL File E161336
