The advantages of the buried resistance buried capacity process include:
1. Space saving
Since the resistors and capacitors are embedded directly into the internal layers of the board, it can save the space of the PCB board and make the whole board more compact.
2. Reduce circuit noise
Resistors and capacitors embedded in the internal layer of the board can reduce the circuit of electromagnetic interference and noise, improve the stability of the circuit and anti-interference ability.
3. Improve signal integrity
Buried resistance buried capacitance process can reduce the circuit signal transmission delay and reflection loss, improve the integrity and reliability of signal transmission.
4. Reduce the thickness of the PCB board
However, buried resistance buried capacitance process will be relatively complex in manufacturing and maintenance, because the resistors and capacitors can not be directly observed and replaced. In addition, buried resistance buried capacitance process is usually used in high-end electronic products, the cost is also relatively high.
When it comes to high-density circuit design, the PCB buried resistor buried capacitor process becomes a very useful technology. In traditional PCB layout, resistors and capacitors are usually soldered to the PCB surface in the form of patches. However, this layout method causes the PCB board to take up more space and may cause noise and interference on the surface.
The Buried Resistor Buried Capacitor process solves these problems by embedding resistors and capacitors directly into the internal layers of the PCB board.
The following are the detailed steps of the PCB buried resistance buried capacitance process:
1. The production of the internal layer
In the production of PCB boards, in addition to conventional layers (such as the outer layer, the inner layer), but also need to make a separate internal layer specifically for buried resistance buried capacitance. These internal layers will contain buried resistors and capacitors in the area. The production of internal layers usually use the same technology as conventional PCB manufacturing, such as plating, etching, etc..
2. Resistor/capacitor packaging
Resistors and capacitors are packaged in special package forms in the buried resistance and capacitance process in order to be embedded in the internal layers of the PCB. These packages are usually thinned to accommodate the thickness of the PCB board and have good thermal conductivity.
3. Embedded resistors/capacitors
The buried resistance and capacitance process is accomplished by embedding resistors and capacitors into the internal layers of the PCB board during the fabrication of the internal layers. This can be achieved in a variety of ways, such as using special pressing techniques to embed resistors and capacitors between the inner layer materials, or using laser technology to etch cavities in the inner layer materials and then fill the resistors and capacitors in.
4. Connection layer
After completing the internal layer of buried resistance and capacitance, connect it to other conventional layers (e.g., the outer layer). This can be achieved through conventional PCB manufacturing techniques (e.g. lamination, drilling, etc.).
Overall, the buried resistor buried capacitor process is a highly integrated technology that embeds resistors and capacitors in the internal layers of a PCB board. It saves space, reduces noise, improves signal integrity, and makes PCBs thinner and lighter. However, due to the complexity and increased cost of manufacturing and maintenance, the buried resistor-buried capacitor process is usually used in high-end electronic products with high performance requirements.
