Copper Flex Circuit

In its simplest form, a flexible circuit is a vast cumulation of conductors bonded to a thin dielectric, or insulating, film.

Silver or copper may be used as an electric conductor. In a Copper Flex Circuit, a very thin sheet of copper is first laminated to the flexible film substrate then chemically etched away, leaving copper traces. The etching process is not as environmentally friendly and more expensive than screen-printing silver traces.

Copper Flex Circuit options include:

Single & Double SidedPolyimide or PolyesterTin, Nickel, Gold Plating

Comparison Chart
Characteristic	Silver Ink	Copper
Printing vs. Etching	Electric conductors are screen-printed onto the film substrate.	Copper is chemically etched away, leaving conductive traces. More expensive than screen-printing.
Pliability/Weight	Silver traces are lightweight and more flexible than solid copper traces.	Solid copper traces are heavier and more durable than softer printed silver traces.
Conductivity	Resistivity approx 50 mOhms/sq1mm x 80 mm trace = 4 Ohms0.5mm x 80mm trace = 8 Ohms	High
Price	Low to Moderate	Expensive to very expensive
Soldering	No	Yes
Pitch	Thin	Possible pitch 0.5mm and 0.3mm for ZIF connector
