How do you approach design verification and validation testing for PCBs?
PCB Layout Engineer Interview Questions
Sample answer to the question
When it comes to design verification and validation testing for PCBs, I follow a systematic approach. I begin by thoroughly reviewing the design specifications and requirements to ensure a clear understanding of the expected performance and functionality. Then, I develop a comprehensive test plan that includes both functional and electrical tests. I use industry-standard testing equipment and software to perform these tests and collect data. Once the testing is complete, I analyze the results and compare them against the expected outcomes. If any discrepancies are found, I investigate and troubleshoot the issues. Finally, I document the test results and provide a detailed report to the relevant stakeholders.
