You have bought the wrong tool for the job, sadly. That's the bad news.
Now the good news - that microscope has replaceable lenses, both the objectives and oculars (eyepieces). Go back to Amscope and get a combination that will give you about a 5x to 10x total magnification, that's what is the most useful for general work.
I have the same microscope and I have asked the UK seller to replace the stock lenses with 1x and 2x objectives (there were two sets in the kit) and 5x and 10x eyepieces, giving me the range from 5x to 20x magnification - which is plenty for soldering and inspection. The original had like 40x magnification which is completely useless for this type of work. Most often I am using only the basic 5x, changing to 10x only to work with very very tiny components (plus changing the lenses is a hassle on this scope, requiring removing tiny setscrews - but you do get what you pay for ...)
Your 10x is way too much if you want to see a huge component like TQFP 100 in its entirety. Even at 5x it may not be possible or it will be really just.
