What is the primary goal of Design for Testability (DFT)?
Correct!
Wrong!
To make it easier to test a PCB and identify faults during manufacturing.
Which technique is commonly used to improve testability in PCBs?
Correct!
Wrong!
Boundary scan is a technique that allows testing of IC interconnections without physical probing.
What does reliability testing assess in PCB design?
Correct!
Wrong!
Reliability testing assesses durability and performance over time under stress conditions.
How does Design for Reliability (DFR) complement DFT?
Correct!
Wrong!
DFR focuses on improving the robustness and lifespan of the PCB.
What is the role of built-in self-test (BIST) in PCBs?
Correct!
Wrong!
BIST enables the PCB to test itself automatically without external equipment.
Which factor most affects PCB reliability?
Correct!
Wrong!
Thermal cycling and mechanical stress most affect PCB reliability.

What does fault coverage indicate in testability?
Correct!
Wrong!
Fault coverage measures the percentage of detectable faults during testing.
Why is modular design beneficial for testability?
Correct!
Wrong!
Modular design allows testing individual sections separately, simplifying diagnostics.
What is the benefit of using test points on a PCB?
Correct!
Wrong!
Test points provide accessible locations to probe signals during testing.
