MacDermid Alpha Electronics Solutions Copper Thinning: CircuEtch 100

CircuEtch 100 is a high-speed peroxide-sulfuric copper etch suitable for various printed circuit manufacturing applications. Product Overview CircuEtch 100 is the product of choice for controlled copper thickness reduction in CO₂ LDD, LED, and PCB applications. During etching, the copper surface is “polished,” resulting in reduced surface roughness—even at high etch rates. A wide range of etch rates can be achieved by adjusting operating conditions.
