The design of printed circuit boards is based on circuit schematics to realize the functions required by the circuit designer.
A circuit board is a compact circuit configuration system that reduces the need for cables and produces a rugged and small circuit.
The printed circuit board was invented by Austrian engineer Paul Eisler in 1936,and was quickly adopted due to the stimulus of the Second World War framework to a large extent.
PCBs are also generally regarded as very complex electronic components,which can only be used by electronics professionals.Yes,they can be very complicated.But in this section, we will uncover its mystery and see if anyone can design their own PCB.
The PCB consists of copper layers that are insulated from each other, and these copper layers make up the circuit.In the next article in this series,we will cover each of these aspects in detail, but for now, we are left with this summary.
We will mount/solder electronic components on the PCB board,which can be PTH (Plated Through Hole) or SMD (Surface Mount Device).In both cases (PTH and SMD) there are various components. Resistors, capacitors, coils, transistors,integration.
The conductive tracks on the PCB and the mounted components together form the final circuit. If we don't have a PCB,we can connect the components together, using a breadboard or breadboard and solder. PCB saves all our work.
Avoid cable confusion. Connect and disconnect. "This pin was bent when removed." "Look where this cable comes from." "I have two pins soldered together." "This connection generates electrical noise." Most importantly, this does not work and this has been destroyed.
Logically speaking,the biggest difficulty lies in the design of the circuit. The more you know about electronics, the more complex and useful the circuit board you make (this also happens if you use a breadboard).
But, as we have seen, despite its appearance, PCB itself is a simple concept. The simple conductive track saves us from using a lot of cables, and it provides us with a powerful and safe way to manufacture electronic circuits.
In conclusion
So far, we have seen the introduction of this new PCB design part and why we should not be afraid of them. Today, anyone can make custom PCBs.
