Model : Flexible Leiterplatte
Flexible Printed Circuit Board, it can work with multi-sides. The single-side flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film. The component termination features are approachable only from one side. Holes can be formed in the base film (PI + Copper) to allow component leads to pass through for interconnection, normally by welding. The surface can be covered by protective-coating over circuit or without. Also it can be welded on many components such as led, resistant, Metal-dome and more. on and allowed the board to conform to a desired shape, or to flex during its use.
