2. Copper Layer: This conductive layer sorts the electrical pathways.
3. Solder Mask: A protective layer that stops limited circuits by insulating the copper traces.
4. Silkscreen: Printed labels and symbols for parts, aiding in assembly and troubleshooting.

How Elements Join and Communicate

Digital elements like resistors, capacitors, transistors, and built-in circuits are mounted over the PCB and soldered for the copper traces. These traces work as electrical highways, making sure the correct circulation of present-day in between elements. This interconnected community will allow complicated functionalities, from processing knowledge to powering shows.
