MacDermid Alpha, DuPont Teijin Films and Sheldahl Inc., enter into a strategic relationship to offer Low Temperature, PET-based Flexible Printed Circuit (FPC) Assemblies

MacDermid Alpha Electronics Solutions, the world leader in the production of electronic soldering and bonding materials, DuPont Teijin Films, the world’s leading differentiated producer of Mylar® and Melinex® branded PET and PEN polyester films  and Sheldahl Flexible Technologies, Inc, a wholly owned subsidiary of Flex Ltd., has been delivering reliable, materials, flexible and printed electronics., have entered into a strategic relationship to offer Low Temperature, PET-based flexible printed circuit assemblies.

This collaboration will enable a complete and holistic solution, starting from world class Polyester Films, to state-of-the art FPC fabrication and low temperature soldering assembly.

This radical technology has the potential for three key inflection points:

  • Transition from traditional Polyimide-based (PI) flex circuits to water clear, transparent, state-of-the-art Polyester-based (PET) flex circuits,
  • Fabrication of sophisticated circuitry via use of Surface Mount Technology (SMT), and
  • Ability to attach heat sensitive components, such as Displays, Batteries, Connectors, etc., using standard in-line SMT assembly techniques.

Key benefits to our Customers include:

  • Leading edge Products, technical expertise and applications support.
  • Global supply chain for implementing this technology.
  • End-to-end solution for creating next generation products.


This Win-Win solution of ultra-low temperature processing, for our mutual Customers, will enable smart, thin, lightweight electronics of tomorrow.
