Ferric Chloride (FeCl₃) PCB Etching Agent – High-Quality 75g Chemical Powder for DIY Custom Printed Circuit Board Fabrication

Product Description

Ferric Chloride (FeCl3) Etching Powder is an essential chemical for engineers, students, and hobbyists looking to create professional-grade custom PCBs at home. This powerful etching agent is specifically formulated to quickly and efficiently dissolve unwanted copper from copper-clad boards, leaving behind your precise circuit designs. At Robogears, we provide this high-purity crystalline version because it offers a longer shelf life and more consistent results than pre-mixed liquid solutions. Simply mix with water to create a potent etching bath that can be reused for multiple circuit fabrication sessions.

Detailed Key Features

• High Etching Efficiency: Rapidly removes exposed copper layers while maintaining sharp edge definition for your circuit traces.

• Economical & Reusable: A single 75g pack can be mixed to create a solution that remains effective for multiple small-to-medium PCB projects if stored correctly.

• Versatile Application: Ideal for all types of copper-clad laminates, including FR4, phenolic, and flexible substrates used in various electronics projects.

• Stable Crystalline Form: The anhydrous solid form ensures that the chemical remains potent for long periods without losing strength due to evaporation or leakage.

• Professional Grade Results: When used at optimal temperatures, it produces clean, bridge-free traces suitable for fine-pitch component mounting.

All Technical Details

• Solubility: Highly soluble in water; the dissolution process is exothermic (releases heat), which actually aids the etching speed.

• Acidity: The resulting solution is highly acidic; use only plastic or glass containers for mixing and storage.

• Boiling Point: ~315°C (Anhydrous), providing high thermal stability during storage.

• Appearance: Ranges from dark brown to blackish crystalline solid in its concentrated form, turning yellow-brown when diluted.

• Melting Point: ~306°C, ensuring the chemical remains solid even in high-temperature workshop environments in Pimpri.
