PTF(Polymer Tick Film) process introduction


Polymer Thick Film (PTF) flexible circuits are manufactured by screen-printing conductive ink onto flexible substrates such as PET (Polyethylene terephthalate). It can be single layer or multi-layers circuit by further screen-printing dielectric materials as insulating layer and applying through-hole technologies.

Notices for Screen-Printing on PET (PolyEthylene Terephthalate)

The PTF uses silkscreen to print the silver and carbon combination conductive inks on PET substitute to reach low cost purpose as compare with FPC. Unfortunately, the screen-printing has some ability limits. Especially for small trace width and small space.

  • PTF: Polymer Thick Film
  • PET: Polyethylene Terephthalate
  • FPC: Flexibility Printing Circuit
