  • Electrical component housing structures and their method of manufacture
    Patent number: 6700074
    Abstract: The invention provides a carrier housing assembly holding a flexible foil having conductive tracks in which the housing assembly has a plurality of parts each having a respective securing mechanism, the securing mechanisms being mutually engageable to provide a predetermined spatial relationship between the part, thereby providing the flexible foil with a predetermined spatial arrangement. The housing assembly is particularly relevant to component housing assemblies where electrical components are held in place and connected to connecter pins via the flexible foil. In a further aspect of the invention, there is provided methods for manufacturing a foil carrier housing assembly out of a flexible foil comprising conductive tracks at least one electrical component, at least one electrical contact element, at least one component housing and a carrier housing.
