🧪 Electroless Plating: Uniform Metal Coating Without Electricity
📘 What Is Electroless Plating?
Electroless plating is a chemical-based metal coating process that relies on autocatalytic reactions to deposit a uniform layer of metal—no electricity required. It’s perfect for complex geometries and non-conductive substrates like plastic or ceramics.
🔄 Process Workflow
- Surface Preparation – cleaning, etching and degreasing
- Activation – applying catalyst (e.g. palladium-based)
- Chemical Bath Immersion – substrate submerged in plating solution
- Uniform Deposition – even coating through reduction reaction
- Post-Treatment – rinsing, drying and optional heat treatment
🧬 Common Types of Electroless Plating
