Preview Questions Test Engineer (Electronics) | Role Specific Skill

Question 1: In a test plan, which of the following should be clearly defined to ensure successful test execution?

Which action should you take?

Choose only one option

The testing tools' cost and procurement process

The expected delivery date of the final product

Test objectives, environment, and acceptance criteria

A detailed description of the marketing plan

Question 2: Which of the following is the best method for testing a passive component for its ESR (Equivalent Series Resistance)?

Which action should you take?

Choose only one option

Measure the impedance at the rated frequency

Apply a DC voltage and measure the current

Use a digital multimeter to check resistance

Use an LCR meter at the specified test frequency

Question 3: What is the key challenge when testing circuit boards with very high component density?

Which action should you take?

Choose only one option

Relying only on visual inspection to detect failures

Managing probe access to specific test points without shorting components

Ensuring the test equipment supports all the required test points

Avoiding excessive heating of the components during tests

Question 4: In signal integrity testing, what does the term "return path" refer to?

Which action should you take?

Choose only one option

The path that the signal follows through the PCB

The path the signal takes after it exits the PCB

The path taken by the current to complete the circuit

The path for the signal to return to its source

Question 5: What is the role of termination resistors in maintaining signal integrity in high-speed circuits?

Which action should you take?

Choose only one option

To amplify the signal to overcome noise interference

To match the impedance of the transmission line

To filter high-frequency noise in the signal path

To prevent power loss in the signal path

Question 6: If an LED on a circuit board is not lighting up, which of the following would you check first?

Which action should you take?

Choose only one option

Test the voltage on the cathode pin of the LED

Inspect the PCB for short circuits near the LED

Verify the forward voltage across the LED

Measure the current through the LED
