Double Sided Flexible Circuits & Circuitries
Double Sided Flexible Circuit Stack Up / Structure
As double sided FPC is the most popular type of flexible circuit, so there’re various combination of different material. There’re five basic layers, from top to bottom (didn’t list the adhesive between):
- Coverlay (top)
- Copper trace (top)
- Polyimide: between two copper trace
- Copper trace (bottom)
- Coverlay (bottom)
Here is the most popular stack up /layer up of double layer flexible circuits:
Adhesiveless laminate also available and in fact, it’s very popular, as engineer want thinner thickness, bigger bend radius, chemical and high temperature, low outgassing, dimensional stability, more flexibility, longer life cycles, and impedance control and so on.
