Low costs, Especially for High Volume Orders 2 Layer PCB
Introduction
2 Layer PCB with two copper traces, also known as “Double Sided PCB” (D/S PCB). and required PTH, but it lacks buried or blind holes. Besides, Components can be constructed on both the top and bottom sides of the board. eliminating the need to worry about where to place components on the board. and avoiding the usage of through hole components. consequently, which are always more expensive than SMD ones.This is currently one of the most common types of PCB on the planet. and we can provide a 24-hour quick-turn service for our customer.

Application of Double Layer PCB

Medical Devices
Most medical devices use a PCB with a high thickness, which helps them be as small and dense as possible. This makes it easier to make medical devices, which need to be small and light. PCBs used in a wide range of devices. from small ones like pacemakers to much bigger ones . like X-beam equipment or CAT scan machines.

Machines used in Business
Most of the time, PCBs used as parts of strong mechanical devices. Thick copper PCBs used in places where one-ounce copper PCBs don’t meet the needs. Some things that would benefit from having thicker copper PCBs are engine controllers. high-current battery chargers, and modern load analyzers.

Lighting
Aluminum PCBs used to make LED lighting systems. are also becoming more popular as LED lighting systems . become more popular because they use less power and are more productive. These PCBs act as heat sinks and can exchange more heat than a regular PCB. The same PCBs made out of aluminum are used for both high-lumen LED applications and basic lighting systems.

The Auto and Airplane Industries
Both the car industry and the aviation industry use flexible PCBs. which made to handle the high vibrations that are common in both fields. Depending on the decision and design, they can also be very light. which is important when making parts for transportation projects.
FAQs For Double Sided PCB
What is a double sided PCB?
Double sided PCB covered Copper on both sides, top and bottom, of the 2 layer PCB (double-sided PCB). There is an insulating layer in the centre of the printed circuit board, which is a common component. The fact that both sides laid out and soldered considerably minimizes the difficulty of layout. leading to its widespread use.
What is the difference between single-sided PCB and 2 layer PCB ?
Single-sided PCBs have traces only on one side. but double-sided PCBs have traces on both sides, on both the top and bottom layers. Components and conductive copper put on both sides of a double-sided PCB. which causes the trace to meet or overlap.
How do You Make a double-sided Circuit Board?
To create a two-layer PCB, The most used substrate is FR-4. Once the substrate is in place, copper in layers.The signal layer is the initial layer added. This is where the electrical signals will be transmitted.The ground layer is the second layer you added. Here is where the electrical signals will return to the device.This layer of prepreg is an insulating substance. Consequently, it serves as an insulator between the layers.
The solder mask is a thin covering of green or black plastic . that prevents short circuits and corrosion on copper.
Finally, Silkscreen is a white or yellow printing on the PCB. that displays the names and values of the components.
How does a double-layer PCB work?
Electrical signals are routed between the two layers of copper on a two layer PCB. Surprisingly, these signals can be digital or analog. Furthermore, the dielectric substance in the middle of the board. To prevents these signals from interfering with one another.
How do you decide between 2 layer and 4 layers of PCB?
In general, multilayer PCBs utilized in more complex electronics. whilst 1 or 2 layer PCBs utilized in simpler devices. Obviously, multilayer PCB is more popular among electronic engineers. due to its ability to give a high signal intensity. And two-layer PCBs are the most prevalent variety. since they can accommodate interconnections on both sides. Therefore, we will explain the distinction between 2 layers and 4 layers PCB. as well as how to select the appropriate type for your project.
What is the difference 2 Layer PCB to 4 Layers PCB?
Stacks Up
On a 2-layer PCB stackup, it is clear that the first layer, or the top layer, is the signal layer. The 0.0014-inch layer of copper. There is about 1 oz of copper in the layer. which has a good effect on boards with a thickness of 0.062 inches, or about 10% of the final thickness. Depending on the parameters, these values may be different according your board.
Designs
On the one hand, the design of a 2-layer PCB can give you more room to put a conductor pattern on the board. The surface is, of course, twice as big as a single-layer PCB. Vias in a two-layer PCB to make electrical connections. that allow the traces to routed to the other side of the board.
Function
There’s no doubt that it has more functions in a two-layer PCB because propagation delays. and other problems don’t happen when a ground plane is used in the microstrip traces. But most people use the 4-layer PCB design, which has a ground plane layer, a VCC plane layer, and two signal layers. But the design puts a lot of thought into impedance and delays in propagation.
Cost
There’s no question that 4 layers PCB is more expensive than 2 layers PCB. because the design is more complicated and the boards are more sensitive. Also, there is a factor in how much a 4-layer PCB costs that affects the quality of the signals. This is done by lowering the levels of distortion and signal propagation. So, more and more electronic engineers are choosing 4-layer PCBs . because the signals are better and there is less interference.
