  • ELECTROFORMED COMPONENT PRODUCTION METHOD
    Publication number: 20160115610
    Abstract: A contact element (25) (electroformed product) is produced by electroforming. The contact element (25) has a surface on which an insulating film (28) having been formed by use of a dry film resist or the like is provided. In a process of producing the contact element (25), the insulating film (28) is provided after a step of producing the contact element 25. This makes it possible to provide electroformed components configured so that respective electroformed products (contact terminals) are arranged at narrow pitches while maintaining electrical insulation of the electroformed products from each other.
