While single-sided PCBs are simple and ideal to use when possible, many circuits require two sides. Double-sided PCB boards offer a wide variety of possibilities for circuit board designers because they have more surface area and flexibility when routing traces. Using two sides instead of one also allows for a smaller board size overall, which can be important when building small-scale, integrated devices.
What is Double-Sided PCB?
Strictly speaking, the Double-Sided PCB is one kind of the important PCB boards which is useful in PCB industry. They allow for the routing of traces around each other by jumping between a top and bottom layer by way of vias. Generally speaking, There are lines on both sides! The common PCBs can be seen such as, Rigid PCB, Flexible circuit board, Aluminum PCB and Metal Core PCB.
It need circuits on both sides. Via is the holes on boards, coated with metal and it can connect wires on both sides. Because the area of Double-sided PCB is twice as large as the Single-sided PCB, and because the wiring is interleaved, which is better suited for circuits that are more complex.
Someone may feel confused that if one Double-sided PCB, wires on both sides while Electronic parts only one side, is this a Double-sided board or a single onel? The answer is obvious. This kind of board is a Double-sided board, it's just install a component on the Double-sided board.
Double sided circuit boards are one of the most popular types of PCBs as they enable manufacturers to produce more complex circuits, which can benefit uses in higher technology applications and electronics. There is an abundance of applications and electronics which double sided PCBs can be used in including: lighting systems, vending machines, amplifiers, car dashboards, and many more.
Double Layers PCB expands design capability and reduces physical sizes.
Double-Sided PCB material
The foundation of the PCB is the rigid fiberglass laminate. When it comes to the manufacturing process, there are many types of PCB materials that may be used. Which material gets used is determined by the PCB designer in order to meet electrical, temperature, and other related properties. The standard material we usually used is glass fibre, often referred to as FR4.

Benefits of Double Sided PCBs
Double sided PCBs are a widely used component for various applications as it enables more flexibility in the design and more complex circuits. Here are a few advantages of double sided boards:
More space for components: By having conductive layers on both sides, a double-sided PCB has twice the room for components as a single-sided PCB. Increase circuit density and complexity with ease.
Numerous applications: Double-sided PCBs have the circuit complexity to be used in many common electronics at a reasonable price. Use double-sided PCBs to create popular electronics for everyday use.
Effective use of space: A double-sided PCB comes in the same size as a single-sided PCB, but with double the component room. Design more complicated projects with the same amount of space.
Cost-effective: Double-sided PCBs have the capacity to be used for plenty of projects and have a lower price than multilayer PCBs. Avoid paying for extra layers when two will do.
More design options: At a relatively low cost, you can greatly expand the number of projects possible for your capabilities and budget. Create innovations that you couldn`t with a single-layer PCB.
Suitable for sinking and sourcing current: You can use the bottom layer of a double-sided PCB as a ground copper pour for sinking and sourcing currents. Redirect your PCB`s current while leaving the top layer free.
Double sided PCB boards is different from Single-sided PCB.
Single-sided PCB is the basic one, the spare parts are concentrated in one side, and the circuit is concentrated on the other.Because the wires only appear on the one side of themso we called Single-sided PCB. Because the single-sided PCB has many strict restrictions on the design circuit (because only one side, the wiring cannot cross and must move around the individual path), so it only used on earlier circuits.
Single-sided PCB diagram mainly used Network Printing(Screen Printing), that is, resist on copper surface, After etching, mark the welding resistance, and then finish the hole and the shape of the part by punching.
Single sided Printed Circuit Boards are widely used in many electronics whereas double sided circuit boards are often used in higher technology electronics.
Single sided printed circuit boards are commonly used in an array of electronics and applications, including: camera systems, printers, radio equipment, calculators, and much more.
Benefits of Single Sided PCBs
Single sided circuit boards are considered to be one of the best choices for a wide range of applications due to the advantages that it provides. Here are a few advantages of single sided printed circuit boards:
The cost of manufacturing and producing single sided circuit boards are very cost-effective and affordable due to the simple and basic designs. These types of PCBs are widely understood by various manufacturers which makes single sided boards the best choice for circuit designs that are simple and low density.
As single sided boards are less complex, there will undoubtedly be fewer problems during the manufacturing stage, which enables manufacturers to produce these boards at higher volumes and at faster speeds. Due to this, they are commonly used in many applications and electronics.
With higher volume orders, single sided circuit boards can be more affordable and available at reduced costs.
Double-Sided PCB Applications
Many of the electronics found in everyday life function on double-sided PCBs. Applications of double-sided PCBs include:
Double-Sided PCB fabrication
