Telecom components don’t have room for trial and error. The materials used especially in RF paths directly affect signal strength, reliability, and long-term performance.
Silver plating continues to be the top choice for key reasons:
- It has the highest electrical conductivity among all metals
- It reduces RF loss
- It helps control PIM (Passive Intermodulation)
- It stays stable under varying operating conditions
With selective plating, silver is applied only where it’s needed. That means performance without unnecessary cost.
Where Silver Makes a Difference
Connectors
Signal contacts need clean, low-resistance paths. Silver ensures minimal loss at those points.
Waveguides
RF energy travels along the inner surfaces. Silver-plated walls reduce attenuation, especially at higher frequencies.
Antennas
Silver improves radiation efficiency and current flow, helping achieve better signal clarity and strength.
These are not cosmetic choices. They directly affect how equipment performs.
The Skin Effect: A Quick Explanation
At high frequencies, current flows only through the surface of a conductor. This is called the skin effect.
The higher the frequency, the thinner this surface layer becomes. So, only the outermost layer matters. That’s where silver’s conductivity plays a major role improving signal flow and minimizing resistance.
Why Telecom Engineers Still Choose Silver
Selective silver plating is not about tradition, it’s about function. It improves performance, controls interference, and extends the life of critical components.
At Sargam Industries, we help teams apply silver precisely where it matters.
No excess. No compromise. Just reliable plating, designed for real performance.
