Hi Guys
I'm totally new to this. I'm trying to build a 4 channel opamp (boost my signal about 100x)
I'm hoping someone has the time to quickly check my design and see if it makes sense and perhaps let me know how to improve it.
Thanks
Jacob

No capacitors?

You mean to filter the input?
Hi,
At least capacitors should be added on the supply...
I don"t know the purpose of your circuit but you should add at least a small one capacitor (10 to 100 nF) placed near the power supply input pins of the LM324, and a electrolytic caacitor (few µF) rignt after the supply input connector.
En large 24V supply trace, and for the GND you can enlarge the trace or better add a GND plane (polygon).

hi,
I've viewed your layout and edit it.
some tips for your next pcb
* first of all: place parts, route power supply & gnd, critical tracks like bus and the all the other things
* layout the pcb by following your nets of the schematics
* try parts in different ways THT (horizontal / vertical) or SMD
* route the tracks as short as possible
* place holes to fix or parts to screw your pcb on something
An example off your pcb with short tracks, etc. is attached.
