Immersion gold plating vs. electroless gold plating
2008-2-11 · 2003. A. Immersion plating processes do tend to have poorer adhesion than electroplating processes. This is perhaps because the plating process is not metered or controlled by an external electrical source; rather, atoms of the plating deposit on the substrate at the rate of their choosing, often not slowly building a solid crystal structure, but instantly converting from
