摘要: Disclosed is a composition for and applying said method micro etching of copper or alloys during manufacture printed circuit boards. Said comprises salt, source halide ions, buffer system benzothiazole compound as an etch refiner. The inventive especially useful boards having structural features ≦100 μm.
