| titleOfInvention |
Micro-etching composition for copper or copper alloy, micro-etching method, and method for manufacturing printed circuit board |
| abstract |
A micro-etching composition and a printed circuit board fabricated by using the micro-etching composition are provided. The micro-etching composition, comprising a main ingredient consisting of sulfuric acid and hydrogen peroxide and an assisting ingredient consisting of phenyltetrazole and a chloride ion source, can continuously treat the surface of copper and copper alloys to produce fine microscopic pits for improved adhesion to resins without producing a brown or black deposit. The printed circuit board exhibits excellent adhesion between inner layer circuit patterns and insulation resin layers, and is free from haloing. |
