Plating process (11)

Let's take a look at the defects in electroless plating. First, let's review the mechanism of electroless plating. Initially, due to the diffusion theory, deposition on the surface is inhibited, and the center of the through-hole (TH) connects. Next, according to the memory effect, deposition in the center of the TH is promoted, resulting in a smoother surface. Diffusion Theory: Due to strong ex..
