Datasheet

Ferric Chloride Hexahydrate

Preparation The required concentration is approximately 500 grams ferric chloride per litre of working solution. Pour half the required volume of clean water at 20ºC to 30ºC into a suitable vessel and slowly add the appropriate weight of ferric chloride, stirring until the granules are completely dissolved. Make up with water to the required volume. Transfer the made up solution to the etching tank or tray, taking care not to splash.

Directions for use: If using PCB etching tank: Follow the instruction supplied with the tank. 1 litre of solution will etch approximately 0.4 metres squared of 305 gram/metre squared (1 oz/foot squared) copper clad laminate.

Storage If using a PCB tank: The solution may remain in the tank, but the tank heater must be switched OFF and the tank lid must remain properly in position to prevent loss of evaporation.

NOTE: The vapour from the surface of ferric chloride solution will corrode tools and other metal objects in the vicinity.

Disposal. The solution must be disposed of in accordance with Local Authority regulations and in such a way as not to endanger personnel, animals, crops water supplies or contravene local drainage regulations.
