Abstract
The present invention uses the resilient behaviour of a flexible printed circuit board (10), both to mechanically clamp the components (20) in a permanent manner and to achieve good electrical contacts (24) between conducting parts (12) of the flexible circuit board (10) and the components (20). By cutting the flexible printed circuit board in such a manner that small tab-like, resilient members (12,16) are formed, the forces caused by elastically deformed resilient members (12,16) are usable both for mechanically fixing the components (20) and for causing an electrical contact (24). By choosing appropriate sizes of the resilient members (12,16), 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 (24) between the conducting resilient members (12) and the component contact members (22). In such a manner, soldering or gluing may be totally omitted.
