Single Layered PCB Or Multi Layered PCB – Which One To Choose?

Should you use single layered PCBs for your circuit or multi layered PCBs? As both the PCBs have their own advantages, it is important to understand which PCB you should use. But, the choice of PCB depends upon the application you are intending to use the PCB in , and the purpose that it needs to fulfill. Let us take a look at what single layered PCBs are good for, and what multi layered PCBs can do.
What is single layered PCB?
Single layered PCBs are those circuit boards that have all the components on only one side of the board, with the conductor pattern on the other side. These PCBs are very easy to manufacture, thus also cheaper in cost. They are used for simpler devices as no wires can cross if the circuit is to function correctly.
What is multi layered PCB?
Multi layered PCBs are those circuit boards that have one or multiple conductor patterns inside the board, which increases the area available for wiring. These PCBs have multiple layers combined into one by laminating or gluing several double-sided circuit boards together, with insulating layers in between. The most popular multi-layered PCBs are those that are between 4-8 layers. Obviously, more layers can be added as required, depending upon the various demands of the circuit. But, there are always even number of layers, as odd number of layers can lead to issues with the circuit board, such as warping and twisting after soldering. Whatever the number of layers, multi-layered PCBs are used in complex applications, such as computers, mobile phones, GPS technology, X-ray equipment, and heart monitors. But, because of such complex construction, it takes a potentially longer time to manufacture them, which leads to higher manufacturing costs. Also, multi-layered PCBs are comparatively difficult to repair. Thus, you should keep all these points in mind while planning to purchase a multi-layered PCB.
How to identify multi-layered PCBs?
In order to identify whether a particular PCB is single layered or multi layered, you can shine a light into the edge in an attempt to see the copper planes, which can help you see signal traces. This works only if the copper comes close to the edge. Using a bright light source, you can see if a board has inner layers, even if it doesn’t have blind vias.
Single layered PCB or multi layered PCB – Which one is for you?
With the above information, you are now in a better position to decide as to which PCB is better for you. In case of simpler applications, you can use single layered PCBs; and for complex applications, where you don’t mind paying a little extra, you can opt for multi-layered PCBs.
