ABSTRACT:
A high density interdigitated symmetrical separable lead frame for use in fabricating light-emitting diodes. A plurality of protection bars protects the unseparated lead frame from damage during initial handling and plating processes. The frame is separable into two unitary segments for attachment of light-emitting diode assemblies. Substantial savings are realized in material costs.
