What does scaling top and right mean? And is there a white stripe on the visa fee on the left?

Answer 1

The set of sizes is a clear demonstration of how wide tracks a given board manufacturer can make.
How to solder with a sting is a matter of personal preference. It’s more convenient for me to solder wide and beveled (aka hatchet ) (because Soviet soldering irons in the radio circle had just that), for someone - with a cone.
