P-Flex® PET: Flexible Printed Circuits

It is inexpensive to mass produce compared to polyimide base materials, and it is suitable for environments with high or extreme humidity due to it being resistive to absorbing moisture. Also, parts other than the pattern or components can have a transparent appearance when transparent resist is used.



  • No adhesive layer for copper foil, soldermask
  • The cost of mass production is lower than polyimide.
  • Because it is less likely to absorb moisture than polyimide, it is suitable for use in applications that dislike humidity and high humidity environments.
