Design for Testability (DFT)
Access, boundary scan and self-test provisions make the board verifiable at volume without rework.
Test access
Reserve probe pads and vias for ICT and flying probe.
Boundary scan
JTAG eases complex, dense boards.
Built-in self-test
Simple loops catch faults before shipment.
Key Takeaways
Key Takeaways
- Reserve test points early.
- Use JTAG for dense boards.
- Add self-test where practical.
