What Is Embedded PCB?
Ready to learn more about embedded PCB? As engineers in Viasion state, an embedded PCB is a circuit board with embedded components inside the circuit board design. According to Viasion’s experience, this type of PCB often consists of components such as passive parts like resistors, capacitors, inductors and active parts like semiconductors, which are critical to the operation of the embedded system.
Our engineers point out it also acts as an interface between the embedded system and other components, allowing it to communicate with external devices. Embedded PCB boards are typically found in embedded systems, such as computers, gaming consoles, and embedded electronic control units. They conclude that the design of embedded printed circuit boards is customized to the specific application they will be used for, and they are more efficient and reliable than standard PCBs. More importantly, embedded PCBs offer reliability and flexibility that cannot be achieved with traditional printed circuit boards.

Types of Embedded PCB
When two or three components, such as resistors, capacitors and inductors, are embedded in the PCB, the circuit board can be said to be embedded passive components PCB.

The Application Range and Advantages & Disadvantages of Embedded PCB
Scope of application
Advantages and disadvantages
Embedded PCBs are widely used in lots of high-tech electronics products, especially in IC chips. But it also has its advantages and disadvantages. Please refer to the following details.
As discrete (non-embedded) passive components are not only assembled in large numbers and occupy a lot of space on the PCB board such as GSM phones contain more than 500 passive components, accounting for about 50% of the area of the PCB panel assembly, such as 50% of the passive components can be embedded inside the PCB (or HDI board) to calculate the size of the PCB board can be reduced by about 25%, thus making the number of pilot holes reduce the number of conductive holes significantly, but also to reduce and shorten the connection wires, etc. Therefore, not only can it increase the flexibility and freedom of PCB design wiring, but it also can reduce the amount of wiring and shorten the length of wiring, thus significantly improving the degree of density of the PCB (or HDI board) and shortening the signal transmission path.
The reliability of PCB (or HDUBUM) assemblies can be significantly improved by burying the required passive components inside the PCB. Because of this processing method, the soldering (SMTAK PHT) points on the PCB surface are significantly reduced, thus improving the reliability of the assembled board and considerably reducing the chance of failure caused by soldering points.
In addition, the embedded passive components can be effectively “protected” to improve reliability. As these embedded passive components are used as a whole embedded inside the PCB, unlike discrete (or discrete) passive components with pins soldered (or glued) to the PCB board connection pads, they will not be subject to atmospheric moisture, harmful gas erosion and reduce or damage passive components. Therefore, the way embedded passive components can significantly improve the reliability of PCB assemblies.
Passive components are embedded into the high-density PCB so that the electrical performance of the electronic interconnection has been significantly improved. Because it eliminates the discrete passive components required to connect the pads, wires, and their leads soldered to form a circuit, any such a circuit will inevitably produce parasitic effects, namely stray capacitance and parasitic inductance. This parasitic effect will also become more severe with the increase in signal frequency or square pulse wave front time. Therefore, eliminating this type of fault will undoubtedly improve the electrical performance of PCB assemblies (signal transmission distortion is significantly reduced).
At the same time, because the passive components embedded inside the PCB, surrounded by tight protection, will not change its functional value (resistance value, capacitance value and inductance value) because of dynamic changes in the working environment, it is in a very stable state, which is conducive to improving the stability of passive component function, reducing the chance of functional failure of passive components.
Using such process methods can significantly save the cost of the product or PCB assembly parts. For example, in the study of embedded passive components of the radio frequency circuit (EP-RF) model, equivalent to the low-temperature co-fired ceramic substrate (LTCC) of the PCB substrate (respectively, embedded in the same passive components), according to statistics, the cost of components can be saved 10%, the price of the substrate can be saved 30%. In comparison, the assembly (welding) costs can be saved by 40%. At the same time, the ceramic substrate assembly process and sintering process are difficult to control, while the PCB substrate embedded passive components (EP) can be completed using the traditional PCB manufacturing process, thus significantly improving production efficiency.
Of course, any one process method has certain limitations, the shortcomings of the embedded passive components PCB are.
One is the current embedded passive components with small functional values, for enormous resistance values, capacitance values and inductance values of components, but also the need to develop functional characteristics of the importance of large embedded passive components materials.
Second, the embedded passive components of the operational characteristic value error control are more complicated, especially with screen leakage printing of flat-type embedded passive components materials. As a result, the operating characteristic value error control is more complicated. Although laser technology can trim and control the functional error of the embedded passive components, not all embedded passive components can be trimmed using this method to meet the design technology requirements. The latest research on the embedded method of thin film resistors has improved the accuracy of resistance values.
Thirdly, very skilled engineers are needed for embedded PCB design. So it is very important to find really experienced team for printed circuit boards design for embedded systems.
