The Characterization of Plasma Desmearing in Etching Back Hole
This paper introduces a method of characterizing the plasma desmearing and etching back of the hole. The experiment of the plasma desmearing on the general thickness-diameter ratio PCB (4:1) and high thickness-diameter ratio (17:1) proved that the plasma desmearing has extremely good uniformity, controllability, and repeatability and therefore we can control the quantity of etching back of the hole by using the characteristic method.
