回答“Unstucked electrical components motherboard.”Hey bud. Just ran across your question here, but what exactly do you mean by “unstucked?” If you can clear that up for me i can try to help. This little piece just off the top of my head looks like a basic integrated circuit probable housing a series of resistors, but like i said i didnt look up the identifier yet..
回答“not charging”Just a little hint to give heads up to novice soldering techs as well as some of us who don’t do it every day. When you go to solder a charging port or anything to a board like these try to use only silver solder and also use the smallest gauge you can find. You want to keep your heat as low and localized as possible or you run the risk causing irreversible damage or trashing it all together. Make sure you have a good and tight mechanical connection and use your flux sparingly. Remember you’re not using your heat source to melt the solder. You’re heating up the intended contacts just enough so they can melt the solder. With a little practice and good equipment you’ll find soldering can be fun when you know what you’re doing. In a lot of cases it’s more of an art than a science...lol hope this helps!
