  • Apparatus for reversing lead frame
    Patent number: 6703693
    Abstract: An apparatus for reversing upper and lower surfaces of a lead frame which passes through a silver-plating process in a lead frame manufacturing process includes at least one guide rail having a curved portion for guiding the lead frame to be fallen down and reversed along an arc of the curved portion, and a conveying roller provided under the guide rail to horizontally convey the fallen lead frame. Thus, since the lead frame is reversed through a specific structure without use of any robot, the malfunction problem of the prior art is solved and costs are reduced.
