Introduction

In the world of electronics testing, test probes are indispensable. They establish the temporary electrical connections needed to verify circuit performance, ensuring that devices function reliably before reaching the market.

But when production reaches millions of units, material choice becomes critical. Brass is the go-to material for high-volume test probes because it combines conductivity, machinability, durability, and cost-efficiency.

At AVF Decolletage, we specialize in manufacturing brass test probes with Swiss CNC machining and ISO-certified inspection processes — making them ideal for industries that demand both performance and scale.

Why Brass Is Ideal for Test Probes

Brass offers unique advantages over other materials such as copper, stainless steel, or aluminum:

  1. Excellent Conductivity – Enables accurate signal transmission during testing.

  2. Superior Machinability – Brass can be machined with high precision and tight tolerances.

  3. Durability – Withstands repeated contact cycles without losing performance.

  4. Corrosion Resistance – Prevents oxidation, ensuring consistent readings.

  5. Cost Efficiency – More economical than other alloys, especially in mass production.

High-Volume Manufacturing Advantages

When producing probes in the millions, efficiency is everything. Brass supports:

  • High-Speed Machining – Reduced cycle times on Swiss CAM machines.

  • Consistency Across Millions of Parts – Tight tolerances maintained batch after batch.

  • Lower Production Costs – Allowing competitive pricing for global OEMs.

Plating Options for Brass Probes

To further improve performance, brass probes are often plated with:

  • Gold – Enhances conductivity and resists oxidation.

  • Nickel – Adds durability and wear resistance.

  • Tin – A cost-effective option for certain applications.

At AVF Decolletage, we provide plating certifications with every batch.
