1.4.4. Ease of Maintenance and Post-Production Testing

Try these first

1. 1.

   What is the primary purpose of Design for Testability?

   Hint

   Think about why products need to be tested.

2. 2.

   Define Built-In Self-Test.

   Hint

   Consider how a device can check itself without outside help.

3. 3.

   What does DFT stand for in electronics?

   • Design for Testability
   • Design for Technology
   • Drive for Testability

   Hint

   Recall what DFT emphasizes in electronic systems.

4. 4.

   True or False: Built-In Self-Test enables a system to run diagnostics without external equipment.

   • True
   • False

   Hint

   Think about what BIST allows a device to do.

5. 5.

   Consider an electronic device that frequently fails after deployment, causing high maintenance costs. Propose improvements to its design using DFT principles.

   Hint

   Think about how DFT aids in identifying issues proactively.

6. 6.

   Analyze how the absence of DFT could lead to an increase in product recalls for an electronics company. What could be the long-term impacts?

   Hint

   Reflect on the complexities of device diagnostics in the absence of DFT.
