摘要： A flexible beam lead tape having three layers having trace conductors, a dielectric and a ground plane. Vias extend through the dielectric layer at the first and second ends of the electrical conductors for providing versatile connections to either ends of the conductors. The ends of the conductors may be provided with electrical connections on either or both sides of the tape and may be connected by pressure contact or by bonding. The tape also includes means for aligning the tape with a substrate to which the tape will be interconnected.
