What is double sided PCB ?
The double-layer PCB board with copper on both sides and metallized holes is being called double-layer board. The circuit board on both sides is covered with circuit boards. However, if the wires on both sides want to be used, the appropriate circuit connection between the two sides should be first provided. Today the double sided printed circuit board technology remains the workhorse of the assembly industry. There are near limitless applications for old and new designs.

Single vs double sided PCB
The difference between a double-sided PCB board and a single-sided PCB board is that the single-sided PCB circuit is only on one side of the PCB board, while the double-sided PCB circuit can be distributed on both sides of the PCB board. Wiring of the double sided pcb board are being connected.
In addition to the different production process between double-sided PCB board and single-sided PCB board, there is an additional copper sinking process, which is the process of conducting double-sided circuits.
Are Double Sided PCBs more expensive than Single Sided PCBs?
Generally, yes. The manufacturing process for Double Sided PCBs is more complex, involving additional steps such as through-hole plating. This complexity can lead to a higher cost compared to Single Sided PCBs.
-
Can double sided PCBs be used in high-frequency applications?
Yes, Double Sided PCBs can be used in high-frequency applications. The key is in the material used for the PCB substrate and the precision of the layout. High-frequency PCBs often require materials with low dielectric losses and a design that minimizes signal interference, which can be achieved with careful planning and expertise in double-sided PCB design.

Advantages of double sided PCB
Double sided pcb make it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs;
Since both sides of double-sided pcb board are conductive, a large number of ICs and components can be assembled at any time;
If necessary, the size of the circuit board can be reduced, because double-sided can be used, this type of PCB may save you money because you may only need to use one board;
Double-sided PCB can be used in many different applications and electronic products, double-sided PCB is ideal for demanding applications and advanced electronic products.
