Design for Test

Term from Electronics Manufacturing industry explained for recruiters

Design for Test (DFT) is an approach used when creating electronic products to make sure they can be easily tested during and after manufacturing. It's like building a house with easy access points for home inspectors. When products are "designed for test," it means engineers have included special features that help factory workers check if everything works correctly without taking the whole product apart. This saves time, reduces costs, and helps catch problems early. You might also see this called "Design for Testability" or "DFT" in job descriptions.

Examples in Resumes

Example Interview Questions

Senior Level Questions

Q: How have you implemented Design for Test strategies to reduce manufacturing costs?

Expected Answer: A strong answer should explain how they've added test points to circuit boards, created automated test procedures, or designed special test modes that made testing faster and cheaper in production.

Q: Tell me about a time you had to balance Design for Test requirements with other design constraints.

Expected Answer: Look for examples of how they managed trade-offs between making a product easily testable while keeping costs down and maintaining performance requirements.

Mid Level Questions

Q: What basic Design for Test features do you typically include in your designs?

Expected Answer: Should mention things like test points on circuit boards, self-test modes, or diagnostic connectors that help verify product functionality.

Q: How do you document your Design for Test approach?

Expected Answer: Should describe creating clear documentation about test procedures, test points, and special test modes so manufacturing teams can easily test the product.

Junior Level Questions

Q: What is Design for Test and why is it important?

Expected Answer: Should explain that DFT makes products easier to test during manufacturing, which saves time and money by finding problems early.

Q: What are some basic Design for Test techniques you're familiar with?

Expected Answer: Should be able to describe simple concepts like adding test points to circuits or creating basic self-test features.
