How to unscrew a fucking screw?

Question

Service maintenance

There are 20 screws on the back cover of the laptop, 17 of them were unscrewed without problems, and the remaining 3 creatures do not want to come out. They are small, cross-shaped, still recessed in the case, you can’t even pick them up with pliers. On the Internet, everyone trumpets such typical methods such as drills, rubber bands, etc. And how else can you pull it out?

Answer 1

It is necessary to use the fact that all the screws in the laptop are screwed either directly into the plastic (self-tapping screws), or into knurled threaded bushings, pressed or melted into the same plastic.
Sharpen the solder so that a blunt point is formed (you can even imitate the tip of a Phillips screwdriver, albeit inaccurately), the outer diameter should be less than the outer hole for the screw head (so as not to melt the edges of this hole). Hold the soldering iron perpendicular to the panel (again, so as not to melt it), rest the pointed tip against the screw head, wait for it to warm up, and slowly pull out the screw by itself or together with its threaded bushing. Then, during assembly, you will need to melt the sleeve back.
By the way, before this procedure, all other screws (those that are unscrewed normally) must already be unscrewed.
