开云体育Hello. ? I don't know your soldering shills, but this definitely is on higher level. Forget soldering irons in this case. There are super-fine T12 soldering irons, but the size is still very small. Such parts are usually replaced by use of a hot-air reflow workstation, fine tweezers and a huge magnifying glass or microscope (for looking from bigger distance of 20cm or more).?? If you don't have that equipment, skills and a very steady hand, don't even try it. You can possibly contact a repair center for smartphones or laptops, if they would do an exception and replace the part, but I guess this will cost more than a new tinySA. And another thought:? Is it sure that _only_ this part is the problem and everything else is 100% ok? Otherwise you burnt money and still have a not working device. I talk from my own experience, I am not bad in reflow soldering, but I wouldn't touch that. Am Dienstag, 1.
