Calculations were made of the doped concentration "C0", of the thickness of Cu-film about Cu-treatment and of the junction areas increased by pre-etching.
The effects of current density on the main properties of iron coating were investigated by using low-temperature iron plating technology without pre-etching.

Based on analysis and compare of kinds of iron electroplating methods, a new process of iron electroplating without pre-etching and composite electroplating has been brought forward for restoring.
