AC122500RY

Laminate – Flex

Product Description 

DuPont™ Pyralux® AC is a single-sided copper-clad laminate  

featuring an adhesive-less, all-polyimide dielectric layer. This  

material is ideal for use in single-side clad applications that require  

high density circuitry, along with chip-on-flex attachment. Offered  

with a variety of conductor types, DuPont™ Pyralux® AC provides  

designers, fabricators, and assemblers a versatile option to develop  

their flex circuit solution. 

 

Key Features and Benefits 

  • ED or RA Cu foil available with various surface treatments
  • Excellent thermal resistance from all-polyimide dielectric
  • Reliability during flex/bending enabled by excellent peel strength 

between dielectric and conductor 

  • Certified to IPC-4204/25
  • Pass UL 94 test, UL File E161336
  • RoHS Compliant
