Double-Sided Flexible PCB : Double-sided flex PCB feature two conductive layers with a layer of polyimide insulation between them. The conductive layer’s outer sides can be either exposed or have covers, like a copper pad. Layers are connected typically by plated through-holes, but other methods can be used. Like the single-sided flexible circuits, the double-sided flexible PCB can support additional elements such as pins, connectors and stiffeners.
