PURPOSE:To prevent shorting by providing screen plates which make non-parallel contact with bonding wires and are perpendicular to these at electrode deriving lead edges. CONSTITUTION:Upright screen plates 12E, 12B are provided at the edges of electrode leads 2E, 2B in the positions where bonding wires run and the bonding wires make non-parallel contact with the top edges thereof. This contitution enables undesirable contact shorting of bonding wires during production process. |
