Hi,
Having such loops laid out in your schematic - how would you avoid them on the pcb ?
My personal opinion:
* there is no need for the schematic to be physically organized like the PCB. Not even in parts.
In first place the schematic should as clearly as possible show the connections and the function of the circuit.
Genrally I recommend to use symbols for GND and power supply and so on ... they have no physical meaning for the PCB.
Indeed I don´t like the - non standard - schematic symbols that more show the package of a device than it´s function. In my eyes it makes not much sense to have a schematic symbol with the pins ordered 1-2-3-4... like the package.
Especially with OPAMPS and logic devices where you just see the (package) pin numbers.. where you need to have the datasheet by hand to find out which pin number is the non-inverting input and which is the power supply.
But..
For sure - if it does not hurt readability - it makes sense to show special wiring informations: like where the kelvin connection is placed.
At schematics I prefer the signal (information) flow from left to right (which has nothing to do with PCB) and the higher supply voltage on top the sheet and the most negative supplies at the bottom of the sheet.
On a schematic I may have 4 OPAMPs spread - mabe on multiple schematic pages.. where on the PCB they all are in one package.
***
In the above schematics I don´t like the lengthy POWER and GND nets. I´d rather use symbols or labels.
I don´t like the non 0°/90° lines especially those useless bends, and the unnecessary crossings.
And most of all: they are too small (in resolution) so one can not find out the part values not the pin names.
I miss the power supply decoupling capacitors that are essential when designing power switching applications.
In most cases the schematics should help you. But as soon as the schematic is used for other persons (customer, repair, forum...) it helps if they are easy to read.
But I´ve seen way worse schematics.
