EPL Bath is capable of plating 1:25 to 1:40 aspect ratio through-holes.

Is said to optimize organic additives, solution agitation, cell geometry and plating
current density. The 1:25 aspect ratio was plated with 64% throw in the middle of the hole. The 1:40 gave 53% throw, with zero dog-boning and no increase in surface plating.
