Details of copper plating
The copper plating film obtained by electroplating varies depending on the additives and plating type, but the film hardness is about HV50 to 200.
The hardness of the plating film is about twice that of the copper material hardness of about HV50-100.
Since the processing uses an external power supply, the plating film thickness also differs due to the difference in current flow between the tip of the product where current tends to concentrate and the recessed part where current does not easily reach, so an external power supply is not used. Although it is inferior in uniform electrodeposition to electroless plating, it has many advantages over electroless plating that does not use an external power source.
Practical example of copper plating film
① Base plating
It is used for base plating of Ni, Ni-Cr, Sn, etc.
It is also used as a base plating for materials that dissolve in acid.
② Manufacture of copper foil
It is also used in the manufacture of copper foil used for copper-clad laminates.
③ Circuit formation
Copper plating with good conductivity, physical properties, and leveling is used for electricity (printed wiring board, induction coil) and electronic circuit (copper damascene).
It is also used in the manufacture of waveguides, stampers, partial coating masks, rocket nozzles, and thick plating on the rollers of printing presses.
⑤ Carburizing prevention
When surface hardening of ferroalloy machine parts, it is used for the purpose of covering unnecessary parts with copper plating to prevent carburizing of exposed parts.
⑥ Thermal conductivity
It is used for the purpose of giving thermal conductivity by plating the bottom of iron pots and stainless steel pots with copper.
