microscope AMSCOPE for soldering

Yes, you are probably right. The ultimate stiffness is probably limited by the hardware and material the maker devotes to the stand. I imagine that generating a competitive set of cost-effective marketing bullets, getting favorable first weeks reviews and minimizing shipping costs (to offer "free" shipping) could/would make a two-arm stand less stable than it could be. My impressions about one-arm vs. two are likely colored from buying used microscopes made in a remote and hoary antiquity when the optical and mechanical engineers were firmly in charge.

Thank you for posting the pictures of your microscope that show how well things turned out.

Your AMscope it has same bracket that dual boom chinese microscopes. I think is an advantaje because reducing vibrations, in aliexpress the price for dual boom plus camera is same in my country for a microscope like this with single boom, I will upload review and pictures when microscope arrives.

Single and Double Arm Boom Stands can come in various materials and configurations.

For example, among others, AmScope offers "SAW" and "DAW" (there are also black versions of each):

3" (76mm) Holder Ring
23" Overall Length.
16" Single Arm.
15" High Pillar
9" x 9" x 1-3/4" Solid Cast Steel Base
40 lbs in Weight

3" (76mm) Holder Ring
30" Overall Length
20" Double Arms
17" High Pillar
10-1/4" x 8-1/4" x 2-0" Solid Cast Steel Base
Shipping Weight: 55 lbs

While I happen to use the DAW and find it very flexible as well as highly stable, the SAW looks very substantial and per HobGoblyn it also provides stable viewing.  I think issues with stability might be due to products that use stands/bases, tubes/arms, fittings, and controls that are less substantial.
