Frequently Asked Questions
What does 42° Baumé mean for ferric chloride?
Baumé (Bé) is a scale used to measure the density of liquids. For ferric chloride, 42° Baumé indicates a concentrated, ready-to-use solution that provides effective etching rates for copper PCB fabrication and metalwork without requiring dilution. This is the standard concentration used in most PCB etching applications.
Can 415-1L be used to etch PCBs at home or in a lab?
Yes — MG Chemicals 415-1L is a popular choice for both hobbyist and professional PCB etching. It is ready to use straight from the bottle. For best results, warm the solution slightly (around 40°C) and agitate during etching to improve etch rate and uniformity. Always use appropriate PPE (gloves, eye protection) and work in a ventilated area.
What metals can ferric chloride etch?
Ferric chloride is most commonly used to etch copper, but it also etches brass, bronze, Damascus steel, and stainless steel. Etch rates and results vary by metal — refer to the MG Chemicals TDS for guidance on specific metals and applications.
How do I dispose of used ferric chloride solution?
Used ferric chloride (which contains dissolved copper) must be disposed of as hazardous waste in accordance with local regulations. Do not pour it down the drain. Contact your local waste disposal authority or a licensed hazardous waste disposal service. Refer to the MG Chemicals SDS for full disposal guidance.
What is the difference between 415-1L and 415-4L?
Both contain the same 42° Baumé ferric chloride formula. The 415-1L is a 945 mL bottle sold in cases of 6, suitable for lab, rework, and moderate-volume etching. The 415-4L is a larger 4-liter format for higher-volume production etching. Choose based on your consumption rate and storage capacity.
