Manufacturing, DFM & DFT — question 9 of 10

Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.

You're designing test access for a densely populated board with no room for a full bed-of-nails fixture on 30% of nets, including several fine-pitch BGA power and signal pins. You have a budget for at most 8 dedicated test points and one boundary-scan-capable device already on the board. Describe the test strategy you'd propose, including what you'd verify with each method and what would still go untested.

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
