No, "much care" works. You need to read more, Joe.
Ugh, I was in an electronics class 1st term this school year. The class blew big hairy balls. The kits that we were supposed to make were really easy to do, and required no knowledge about anything.. just following a friggin diagram and directions (plug 18k OHM Resistor into A7 and B5) and that's all it was. Then when we finally get to solder some stuff, the dipshit druggies in the class just solder over and over and get big globs of it and then throw it around after it hardened, so guess what: we use up a whole fucking ROLL of solder in one day. So for one of my kits when I was goofing around (finished in 3 days, heh had 2 left) I was putting a speaker together for fun and the one of the wires was frayed and the other was like, short as fuck.. so I had to solder the frayed wire together and guess what, we didn't have any solder! I hate public school.
