From the project
Automatic PCB Tester
Flying Probe Tester for Single-Layer PCBs
This project is a Flying Probe Tester designed to perform connectivity testing on single-layer PCBs. The system uses two probes to make precise measurements across various points on the PCB, identifying short circuits, open circuits, and verifying component placements and connections.
Key Features Two-Probe System: Includes two probes for flexible testing of connections on single-layer PCBs. Single-Layer PCB Support: Optimized for single-layer boards, providing efficient testing of simpler PCBs. Automated Testing Sequences: Capable of performing…
