Dispositifs de test fonctionnel

Functional Test Fixtures (FCT) are customized end-of-line tools that simulate operating environments to verify PCB performance. Using pogo-pins or connectors, they automate the testing of power, LEDs, displays, and I/O signals, boosting throughput while reducing manufacturing costs.

Functional Test Fixtures (FCT): End-of-Line Excellence

Functional Test Fixtures (FCT) are customized, end-of-line tools designed to simulate a product’s final operating environment. By verifying that PCBs and assemblies meet strict performance standards before shipping, these fixtures ensure high reliability. Using "bed-of-nails" interfaces, pogo pins, or specialized connector jigs, FCT solutions automate the testing of power-up sequences, LED/display outputs, and complex digital or analog I/O functionality.

Core Fixture Architectures

We offer various configurations to match the complexity of your device and production volume:

Bed-of-Nails / Pogo Pin: Utilizes a high-density field of spring probes for rapid, multi-point connectivity.
Dual-Sided Probing: Provides access to both the bottom and top-side components of the PCB simultaneously.
Customized Specialty Kits: Tailored units for unique challenges, including RF shielding, high-voltage protection, and complex electromechanical assemblies.
Multi-Stage & In-Line: Fully automated solutions integrated directly into high-volume production lines for hands-free testing.

Precision Design & Engineering

Our design process focuses on accuracy and durability through high-end engineering:

Advanced Actuation: Secure the Unit Under Test (UUT) using manual mechanical handles or automated pneumatic and electric drives.
Proprietary CAD Logic: We utilize specialized in-house software to automatically align test points with sockets, ensuring perfect registration based on your native PCB design files.
Quality Components: Every fixture features precision guide pins for alignment, high-cycle test probes, and custom-molded gaskets (sealings) for optimal pressure distribution.

Strategic Advantages

Implementing professional FCT fixtures provides a clear return on investment:

Operational Efficiency: Drastically reduces the time and human error associated with manual probing and multimeter testing.
Real-World Simulation: Creates a comprehensive "live" environment to ensure the product functions exactly as intended for the end-user.
Fault Detection: Identifies manufacturing flaws that may have been missed during the In-Circuit Testing (ICT) stage, acting as the final gatekeeper for quality.
