Introduction

Test Probe Manufacturing is one of the most important processes in electronics and precision engineering. Test probes allow engineers to verify that circuits and devices function as designed before reaching consumers. From smartphones to airplanes, reliable probes make quality testing possible.

At AVF Decolletage, we manufacture high-precision test probes with Swiss CNC machining and ISO 9001:2015-certified quality systems. These probes are trusted by industries that demand accuracy, repeatability, and durability. In this blog, we’ll explore the most common applications of precision test probes across different fields.

Electronics Manufacturing

Electronics is where precision test probe manufacturing is most visible. In PCB and semiconductor testing, probes establish temporary contact with micro-scale pads and traces.

Applications include:

  • Printed circuit board (PCB) functional testing.

  • Semiconductor device inspection.

  • In-circuit testing of consumer electronics like smartphones and laptops.

Probes ensure every component works before products leave the factory.

Automotive Electronics

Modern vehicles contain hundreds of electronic systems, from safety sensors to infotainment. Test probes are vital in validating these systems during production.

Applications include:

  • Testing electronic control units (ECUs).

  • Sensor verification for ABS and airbag systems.

  • EV battery module testing.

In automotive test probe manufacturing, probes must withstand vibration, heat, and repeated cycles.

Medical Devices

Reliability is non-negotiable in medical technology. Test probe manufacturing for medical devices requires:

  • Biocompatible materials such as stainless steel.

  • Gold plating to ensure conductivity and prevent corrosion.

  • Ultra-precision machining for small and delicate components.

Applications include:

  • Patient monitoring systems.

  • Diagnostic equipment.

  • Surgical tools and devices.

See our ISO 9001:2015 certification.

Telecommunications & Data

The telecom industry relies on test probe manufacturing to ensure devices can handle high-speed data transfer.

Applications include:

  • RF and microwave device testing.

  • Fiber optic equipment validation.

  • 5G base station and mobile device testing.

As 5G expands, demand for ultra-miniature and durable test probes continues to grow.

Aerospace & Defense

In aerospace and defense, probes must endure extreme environments: vibration, temperature changes, and pressure.

Applications include:

  • Avionics testing.

  • Satellite and communication systems.

  • Military-grade electronics validation.

Here, test probe manufacturing requires gold-plated brass or stainless steel probes with full traceability.
