Single-Layer vs Double-Sided vs Multi-Layer PCBs

You know that you need PCBs, but do you opt for the single layer PCBs, double-sided PCBs, or multi-layer PCBs? Let's dig into the differences and find out!


- Low Cost

- Simple Design

- Simple Production

- Short Lead Time

- High Volume

Single-layer PCBs are well-suited for anything simple, like an alarm clock or a mouse. Simple, effective, and relatively cheap to produce. Double-sided is the next step up, with a higher cost, advanced design, and longer lead time. Double-sided PCBs still use a single layer, but have circuits and components on both sides, allowing for slightly more advanced designs.


- Higher Cost

- Complex Design

- Longer Lead Time

- Higher Power and Speed

- Better Durability

Generally, if you need multiple advanced functions, multi-layer PCBs are the way to go. Think of our cellphones, for example; processor, phone calls, GPS, Wi-Fi, 4G, camera, USB ports, speakers, every component needs space on a PCB, and you will not be able to fit all of this on a single-layer PCB.
