Technic, Inc. Microetchant TechniEtch 1118

TechniEtch 1118 is a proprietary replacement for persulfate and peroxide based microetches. It can be utilized prior to application of plating and etch resists or prior to copper and electrolytic or electroless nickel. TechniEtch 1118 is designed to produce better topography with lower etch depth and with higher copper loading levels. This translates into more panels per volume of etch solution. When compared to generic sodium persulfate, TechniEtch 1118 doubles the number of panels that can be processed per liter and cuts in half the amount of solution sent for treatment.
