Abstract
The present invention uses the resilient behaviour of a flexible printed circuit board ( ), both to mechanically clamp the components ( ) in a permanent manner and to achieve good electrical contacts ( ) between conducting parts ( ) of the flexible circuit board ( ) and the components ( ). By cutting the flexible printed circuit board in such a manner that small tab-like, resilient members ( ) are formed, the forces caused by elastically deformed resilient members ( ) are usable both for mechanically fixing the components ( ) and for causing an electrical contact ( ). By choosing appropriate sizes of the resilient members ( ), the relative strength of the spring force is increased, which even will be large enough to cause a plastic deformation of the material in the contact points ( ) between the conducting resilient members ( ) and the component contact members ( ). In such a manner, soldering or gluing may be totally omitted.
