Frequently Asked Questions
What does 42° Baumé mean for ferric chloride?
42° Baumé refers to the specific gravity/concentration of the ferric chloride solution. This is the standard working concentration for PCB etching — strong enough for efficient copper removal without being overly aggressive on resist materials.
Is MG Chemicals 415 ready to use or does it need dilution?
It is ready to use at 42° Baumé concentration. No dilution is required for standard PCB etching. Warming the solution to 40–50°C can speed up etch times significantly.
How do I dispose of used ferric chloride solution?
Spent ferric chloride contains dissolved copper and must be disposed of as hazardous waste in accordance with local regulations. Do not pour down the drain. Contact your local hazardous waste disposal facility for guidance.
What is the shelf life of MG Chemicals 415 ferric chloride?
Unopened, ferric chloride solution has a shelf life of approximately 2 years when stored in a cool, dark location. Once used, the solution becomes saturated with copper over time and will etch more slowly — replace when etch times become unacceptably long.
Is ferric chloride safe to use at home or in a lab?
Ferric chloride is corrosive and will stain skin, clothing, and surfaces permanently. Always wear chemical-resistant gloves, eye protection, and work in a well-ventilated area. Avoid contact with metals other than copper, as it will etch them as well.
