What is Double Sided PCB?
Double Sided PCB Definition
A double-sided PCB, which is also known as a double layer PCB, 2 layer PCB, has two conductive layers; one at the top surface and one at the bottom of the PCB. It means the circuit and components can be on two sides.
There are two conductive layers in the double-sided PCBs, so they are used for tasks where single-layer PCBs cannot work. The back of the PCB board is also utilized to implement complex designs and get the most out of the space. Due to two conductive layers, the PCB can have more components in a small area, while a similar single layer PCB can have half of the components. Visit our website for more details.
These PCBs are more advantageous and are preferred for various applications. Among all types of PCBs (single layer, double layer, and multilayer), double-sided is mostly used and preferred.

Stack-up in Double Sided PCB - Double sided PCB Design
The stack-up of a double-sided PCB is quite simple. You can assume it as two single-layer PCBs joined together.
The top layer of a double-sided PCB is a conductive layer. After that, there is a dielectric layer in the center, which is the base material of the PCB. At the bottom, there is another conductive layer. Simply put, the dielectric/base layer is sandwiched between two conductive layers.
The conductive layer is made of copper, as it has excellent electrical conductivity and is also cost-effective. Gold or Silver can also be used to make a conductive layer or for its plating.
The base/dielectric layer could be made of various materials. It can be FR-4, Polyimide, PTFE, metal (aluminum, copper, or iron), or any other suitable substrate. If the base material is non-conductive, it behaves as an insulator between the two conductive layers. But if the base layer is metal, then a dielectric layer is also used to create insulation between the layers as it is necessary to prevent short circuits between the layers.
