Two flexible circuit board material introduces

We have discussed Copper Clad Laminates, Copper Foil in this series flexible circuit board material articles.

#1 flexible circuit board material: Adhesive

If you ask some questions about this flexible circuit board material Adhesive, some older designers prefer use A stand for adhesive.
What is the definition of flexible circuit board material Adhesive?
A (Adhesive), acrylic and thermosetting epoxy resin Adhesive
Rubber Adhesive for Acrylic Epoxy resin and Acrylic Mo Epoxy two big systems.

#2 flexible circuit board material: Kapton

What is Kapton?
Kapton is a Polyimide film developed by DuPont in the late 1960s that remains stable across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4–673 K).
But to our flexible circuit board manufacture process, PI (Kapton): Polyimide (poly imide film)

PI for Polyimide abbreviations.

In dupont Kapton, thickness unit is 1/1000 inch lmil.Features to be thin, high temperature resistance, strong resistance, good electrical insulation, FPC insulating layer are all brothers Kapton welding requirements.
