Ferric chloride is oxidizes copper and is used in electronics as a chemical agent for etching circuits and circuit boards. A speedy etch rate creates circuitry paths with a high degree of edge sharpness thus it is excellently suited for etching of highly miniaturized circuitry boards. Our shops keeps ready-made ferric chloride solutions by BUNGARD, which comes in a handy one-liter bottle for easy storage, retrieval and dosing. The solution contains 40 % ferric chloride, can be safely handled and easily processed. There is no residue due to exothermic reactions.
