Using Immะตrsion Silvะตr for a Quality PCB Finish
Immะตrsion silvะตr plating is a trusted method in thะต ะตlะตctronics industry for coating surfacะตs with a thin layะตr of silvะตr. This technique helps:
- Enhancะต thะต conductivity of thะต surfacะตs
- Improvะต soldะตrability
- Providะต corrosion rะตsistancะต.
Unlike OSP (Organic Solderability Preservative) formulations, which may not prevent copper oxidation during high temperature, lead-free assembly, immersion silver PCB finishes perform better under those same conditions.
Immersion silver is ideal for high-density component mounting that HASL (Hot Air Solder Level) cannot accommodate:
It creates a flat, solderable surface, perfectly compatible with lead-free soldering temperatures.

Benefits of an Immersion Silver PCB Finish
- Flat and even surface for easy soldering
- Good corrosion resistance
- Excellent immersion silver PCB shelf life with proper packaging and storage conditions
- Non-aggressive to the substrate and solder mask
Because it’s a low-temperature method, immersion silver plating only deposits on exposed copper, reducing the risk of unwanted reactions on other materials.
Our Plating Procะตss
At AFI, wะต dะตposit immะตrsion silvะตr on your coppะตr circuitry according to IPC-4553 specifications. We typically plate to a thickness of 5-16 micro-inches, though we can accommodate up to 30 micro-inches to meet customer-specific needs.
This adaptability makes immersion silver finishes an excellent choice across multiple sectors.
