Ferric Chloride for PCB Etching (250 Grams)

Product Overview

Ferric Chloride for PCB etching (250 grams) is a reliable etchant solution used to chemically remove unwanted copper from copper-clad boards. This 250 g pack is perfect for hobbyists, students, makers, and small-scale manufacturers who need a precise, consistent etching agent for producing high-quality printed circuit boards.

Key Features

• High-purity Ferric Chloride powder (250 g) formulated for PCB etching
• Fast and consistent etching action for clean, accurate copper traces
• Suitable for single-sided and double-sided PCB fabrication
• Compact quantity ideal for prototyping and small production runs
• Compatible with most copper-clad substrates and common etching setups

How It Works

Ferric Chloride acts as an oxidizing agent that dissolves exposed copper on a copper-clad board, leaving behind the protected circuit pattern. The solution is mixed or applied according to the chosen etching method (immersion tank, agitation tray, or syringe application) and monitored until the unwanted copper is removed.

Applications

• DIY PCB prototyping and hobby electronics
• Educational use in school and university labs
• Small-scale PCB manufacturing and batch prototyping
• Repair and modification of existing circuit boards

Usage Instructions

1. Wear appropriate personal protective equipment: chemical-resistant gloves and safety goggles.
2. Dissolve the required amount of Ferric Chloride in water if using a mixed solution, or use the powder as directed by your etching method documentation.
3. Place the copper-clad board in the etchant and agitate gently to speed etching and reduce spotting.
4. Rinse the board thoroughly with running water once etching is complete; neutralize residues if necessary.
5. Dispose of used etchant and rinse water in accordance with local hazardous waste regulations.

Safety Precautions

Always handle Ferric Chloride with care. Key safety guidance:

• Wear gloves, protective eyewear, and long sleeves to avoid skin and eye contact.
• Work in a well-ventilated area to avoid inhaling fumes or dust.
• Keep the product in a dry, tightly sealed container away from children and pets.
• Do not pour used etchant down ordinary drains; follow local hazardous waste disposal rules.
• In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention if irritation persists.

Frequently Asked Questions

Is this product suitable for double-sided PCBs?

Yes. Ferric Chloride effectively etches both single-sided and double-sided copper-clad boards when used with the correct masking and alignment techniques.

How long does etching take?

Etching time varies with concentration, temperature, agitation, and thickness of copper. Typical etch times range from several minutes to around 30 minutes for standard prototyping conditions.
