Abstract
Permanganate desmear technology has been widely accepted in the US as a quality and cost improvement over the traditional desmear methods. Based on two years intensive research and development efforts the paper describes a technological breakthrough resulting in a new application of permanganate technology: genuine etchback without the use of chrome, sulphuric or plasma.
