PCB stands for "Printed Circuit Board." This is the standard circuit board you will find inside of most electronic consumer products. In addition to being used as electronic consumer products, I think PCB can also be made into tools or artistic creations. First of all, let’s understand what PCB is
PCB is a laminated sandwich structure of conductive and insulating layers. PCBs have two complementary functions. The first is to affix electronic components in designated locations on the outer layers by means of soldering.
The second is to provide reliable electrical connections (and also reliable open circuits) between the component's terminals in a controlled manner often referred to as PCB design.
Each of the conductive layers is designed with an artwork pattern of conductors (similar to wires on a flat surface) that provides electrical connections on that conductive layer.
A standard circuit board has 4 layers that we need to concern ourselves with. This includes the base, copper layer, solder mask and silkscreen layer.
Typically, a circuit board will have two sides, which means there will be a top side and bottom side. Each side can have all four of these layers. This 2-sided arrangement is fairly standard .
The four layers will have different visual effects through different combinations
For example
- Nothing, will see Solder Mask
- Only Solder Mask, you will see Base
- Copper & Solder Mask, you will see Copper
- Only Copper, you will see a darker solder mask Color
- Silkscreen, you will see a white
Understand the structure of PCB, then you can start designing PCB Art. I used the free software EasyEDA, which is free to use, just run in the browser, and if needed, there is an offline desktop application.
I drew an exit sign, do you know what layer combination I used
Finally, it is manufactured by the factory

After about few Days i received my PCBs.
As per normal JLCPCB delivered some super high quality and amazing PCBs.
I hope you all enjoyed this fun little project ，What are you planning to design
