0.2mm thick C19400 foil for semiconductor chip lead frame
The remarkable characteristics of the material are: high strength,
high conductivity, high precision and high softening temperature
resistance, as well as suitable processing properties and
electroplating brazing properties.
It is mainly used for the production of semiconductor chip lead
frame, integrated circuit and electronic discrete devices,
electronic industry connectors, etc.
