I am trying to replace the SSD on a laptop. After a Loctite nightmare that I had while getting the casing off, there's just one last screw between me and getting the job done. Despite being confident that I've got the right screwdriver (a 000 Philips), the thing just won't budge. On top of my fear that I may have threaded the screw, I'm worried that I'm fighting Loctite again.
Fortunately, I know that a common Loctite removal trick involves dabbing some WD-40 on the screw with a cotton bud, letting it soak in, and then doing it again before trying to remove the screw normally. I'm ready to attempt this, but I just can't shake the feeling that WD-40 and circuit boards shouldn't mix.
Is it safe for me to put WD-40 so near to my circuitry? I've included a picture below. I'm hoping for the WD-40 to be contained by the (presumably brass) insert. Better yet, I'm hoping that I'm simply misremembering how WD-40 reacts to PCB. Note: It has been quite rightly said that this appears to be an x/y question, so I will make this note for future readers. The answers given appear to show that WD-40 is safe, which is all that was asked for and is indeed an answer. However, my research indicates that it will be ineffective. This here is the spec sheet for blue Loctite, which is one of the weaker forms of Loctite. Of note, it says that the Loctite only loses 15% of its strength after 500 hours of exposure to acetone. If acetone can only just barely do the job, then I suspect that WD-40 won't be able to do the job at all. In short, this question and its answers seem to show that WD-40 will be safe, but ineffective.
