PCB Functional Testing

End-of-Line Testing

Automate comprehensive testing of assembled PCBs before they leave your production line. The AT1032S can validate digital circuits, analog signals, communication interfaces, and power consumption in a single test sequence.

Typical Test Scenarios:
Verify proper voltage rails across the board
Test digital I/O functionality at various logic levels (1.0V, 1.8V, 3.3V, 5V, even 24V logic level).
Stimulate the circuit with specific voltage patterns
Validate analog sensor outputs
Check I2C/SPI device responses
Measure quiescent and active current consumption

Benefits:
Reduce test time from minutes or hours to seconds
Eliminate human error with automated scripts
Generate detailed test reports automatically and/or feed test results to your dashboard
Achieve 100% test coverage consistency

Bring-Up and Debug

When debugging a new PCB design, the AT1032S serves as a powerful multi-function tool that combines the capabilities of multiple instruments.

Use Cases:
Apply controlled power while monitoring current draw
Stimulate inputs and observe outputs in real-time
Inject test patterns via communication buses
Isolate faulty sections using relay-controlled signal routing
Log long-term behavior (voltages, currents, communication responses)for intermittent issue detection

Bed-of-Nails Testing

The AT1032S can serve as the controller for custom bed-of-nails test fixtures.

Advantages:
32 I/Os provide comprehensive coverage
Relay-switched test points for routing flexibility
Built-in current measurement for short detection
Programmable power supply for device under test

Capabilities:
Coordinate probe positioning (via external motion controllers)
Perform measurements at designated test points
Generate test reports with spatial information
Adapt to different board designs quickly

System Integration Testing

Multi-Board System Validation

For systems consisting of multiple interconnected PCBs, the AT1032S can orchestrate complex test sequences that validate inter-board communication and system-level functionality.
