One of the misconceptions I had about designing a schematic when I started in this field was that the schematic is only a representation of the electrical connections between components.
However, as I began to gain more experience, I quickly noticed that this approach was only suitable for my home projects, not for the professional world, where different people are involved, and good documentation becomes crucial.
The schematic is, in fact, the part of the project that coordinates the layout.
This means that the schematic should guide us during the layout. The schematic is not only a representation of the electrical circuit but also our guide on how and where components should be located, and connected.
For designers who work in a small company where they have to wear many hats and take care of the schematics, layout, testing, and software, this might seem like a waste of time.
I understand this, as I also started this way.
However, in larger companies, you usually have people who specialize in different parts of the project. For example, one person designs the schematics, and another person designs the layout.
The idea is that you want to build the schematics in a way that allows another person to build the layout without needing your input.
Also, if you don't do this, and you leave the company, then your designs become unusable for the company, which then has to go back and reverse engineer your work.
The better you are at designing your schematics, the more valuable the work you do becomes, and the more valuable you become to the company.
This also means the more value they can compensate you with.
I hope this helps,
