What to consider before gold plating

For PCB plating:

 

The solder mask must

  • adhere well to the surface
  • be intended for ENIG-plating
  • be well developed
  • be properly cured

 

Else, there is a risk that the solder mask detaches from the surface resulting in gold-plating of non-intended surfaces.

 

For decorative plating:

 

  • Ideally, base material should be made from cupper or nickel. Else, special pre-treatment is needed for the gold to be able to adhere to the underlying surface.
  • Details must be free from grease and oil
  • Scratches and impurities present before plating will remain visible after plating, why it is often beneficial to polish the detail prior to plating.
  • To create the right conditions for plating, we have cooperative partners that can assist with preparing the details with polishing or a pre-cupper layer when so needed. Contact us to find the right solution for gold plating your detail.
