When you create a product that calls for a flex circuit, one of the first decisions you’ll have to make is whether to order a single-sided flex circuit or a double-sided flex circuit. A single-sided flexible circuit includes one conductor layer on a flexible dielectric film. The conductor layer is typically made of either a metal or conductive polymer. The limiting factor of a single-sided flex circuit is that component termination features can only be accessed from a single side of the circuit.
As its name implies a double-sided flex circuit includes two conductor layers. Most double-sided flex circuits allow for terminations of electronic components on both sides. For many products, the double-sided flex circuit adds more capability than a single-sided flex circuit and is often the preferred choice. However, that doesn’t mean you should automatically discount a single-sided circuit. It might still be a better choice in certain situations.
