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.
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.
Types of double-sided PCB
Double-sided PCBs can be classified into different types. The types are,

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.
Other than the base and conductive layers, there are layers of surface finish, solder mask, and silkscreen. These layers are common in all types of PCBs as they provide extra benefits. The surface finish is for the protection of the copper layer, and it prevents oxidation and corrosion. It increases the life of the conductive layer. The solder mask also prevents the formation of solder bridges and unwanted connections. The silkscreen is used to label the components on the PCB board.

Double sided PCB Manufacturing Process
How To Make Double-sided PCB？
The PCB manufacturing process is very precise, difficult and complicated.
The rigorous manufacturing process ensures the quality and performance of electronic finished products. Although the circuit board can be divided into single-sided PCB, double-sided PCB, and multilayer PCB according to the number of layers of the conductor pattern, the manufacturing process used is only different after the first layer is produced. Please refer to the double-sided PCB and multilayer PCB manufacturing flow chart on the right for more information.
Double-sided PCB Manufacturing Process：DFM –> Sheeting Cutting –> Drilling –> De-Derurr –> P.T.H –> Panel Plating –> Dry Film –> Exposal / Develop –> Etching –> Stripping –> Midd Check/Test –> Solder Resist –> Precure –> Exposure / Develop –> Silkscreen –> Postcure –> Surface Process –> Profile –> V-cut –> Final Clean –> E-Test –> FQC / FQA –> Packing / Shipping.
