Some conformal coatings, which protect PCBs from dust and moisture, can emit ethyl acetate or butyl acetate if they weren't fully cured. The smell is sweet but absolutely revolting.

Wow this absolutely might be the answer!
Ethyl acetate is used to wash flux off PCBs.
It's also used as an artificial flavoring in British "pear drops" which is probably why some people say it smells like pineapple.
