> Should they expect a good performance evaluation?
They should expect that particular incident to not affect their performance evaluation, since it was very much not their fault.
In your hypothetical scenario, your hypothetical junior engineer went to the senior engineer repeatedly for advice, and the senior engineer did not do their job properly:
The lab tech was unhelpful, insisting that it must be something with how I had it wired, encouraging me to re-draw my schematic, check my wires, and so on. It could _never_ be the equipment's fault.
This is a huge failure in mentorship that wouldn't be ignored at a company that actually cares about these things.

What do you mean not their fault? I've seen wrong parts delivered by suppliers, so yes responsibility of an engineer who puts together a circuit is definitely checking that the parts are correct.

Again _never_ the equipment's fault? It wasn't the equipment it was a part. So maybe it was an issue of miscommunication? I find it hard to believe that the lab tech said it could never be the parts, considering how those things are handled in student labs, small parts break all the time.
Maybe, it's true and it was a crappy lab tech, maybe they could not imagine the part being broken, but I've seen the other side of the equation as well, when things don't work students often just throw their hands up and say "it doesn't work" without any of their own troubleshooting expecting the tutor/lab tech/professor to do the troubleshooting for them (quite literally, can you check that we wired everything correctly...).
In my experience this does not get accepted in industry. I acknowledge though what the other poster said, generally in industry incentives are different and someone would have intervened if a project gets held up for 8 weeks by a single person.
Regarding the story, I wonder what would have been an acceptable solution (apart from the lab tech possibly being more helpful?), I as a teacher would have excepted a report which would have given a detailed account of the troubleshooting steps etc. (but it needs to show that a real effort to find the cause, simply saying the lab tech couldn't help is not sufficient). Simply saying "it wasn't my fault because I had a wrong part" shouldn't just give you an A.
