Technical Information
Nickel Plate
 

This is a brief description of our Nickel plating process:

  • Our low stress nickel is a sulfamate based bath.  It is used as a diffusion barrier for copper migration and excellent solderability.  Our nickel meets the requirements of QQN-290 and ASTM 2424.
  • Thickness deposits are typically 100-250 uin when used as an under-plate for gold.  The deposit is semi-bright.
