What is an embedded cavity PCB board?

Embedded Cavity PCB Board is a printed circuit board with an internal cavity structure. Its unique design is that electronic components can be embedded within the board to achieve a more compact and high-performance circuit layout. . This kind of board is often used in electronic devices that require a high degree of integration and compact design, such as smartphones, tablets, drones, medical equipment, etc. Its unique design makes the entire device thinner, more stable and more efficient.

In traditional printed circuit board designs, electronic components are usually fixed to the surface of the board by soldering or insertion. The embedded cavity PCB board makes the entire circuit layout more compact by cutting a cavity inside the board and embedding electronic components in it. This design not only saves space, but also reduces the electromagnetic interference of the circuit and improves the stability and reliability of the circuit.

The manufacturing process of embedded cavity PCB boards is relatively complex. First, it is necessary to design a specific cavity structure according to the needs of the equipment, and use advanced processing equipment to process and cut inside the board. The electronic components are then embedded into the cavity and secured to the inside of the board using a special process. Finally, process steps such as circuit wiring, welding, and testing are performed to ensure the normal operation of the entire circuit.

The design of embedded cavity PCB boards needs to take into account many factors, such as the shape, size, location of the cavity and the layout of internal electronic components. During the design process, engineers need to fully consider the performance, stability, and heat dissipation requirements of the circuit to ensure that the final design meets the needs of the device and has good performance.

In general, the emergence of embedded cavity PCB boards brings new possibilities and challenges to the design and manufacturing of electronic devices. By embedding electronic components into the interior of the board, a more compact and high-performance circuit layout can be achieved, thus providing new directions and ideas for the development of modern electronic equipment.

How to design an embedded cavity PCB board?

Designing an embedded cavity PCB board is a complex and critical task that requires the consideration of multiple factors to ensure the performance and reliability of the final product. During the design process, engineers need to carefully consider key factors such as internal cavity structure, circuit layout, and thermal management, and use CAD software for precise design and simulation verification.

First, designers need to consider the internal cavity structure. Embedded cavity PCB boards usually have internal cavities for embedding electronic components or implementing specific functions. Designers need to determine the size, shape, and location of the cavity to ensure that it can accommodate the required components and meet the circuit layout requirements. The design of the internal cavity should fully consider the compactness of the circuit wiring and the effect of ventilation and heat dissipation.

Second, circuit layout is another key consideration in the design process. Designers need to rationally arrange the location and connection of electronic components to minimize circuit length and signal transmission delay, and improve circuit performance and stability. At the same time, circuit layout also needs to consider issues such as electromagnetic compatibility (EMC) and signal integrity to avoid interference and crosstalk between circuits.

In addition, thermal management is also one of the factors that cannot be ignored in the design process. Embedded cavity PCB boards usually have higher integration and power density, and tend to generate more heat. Designers need to properly design heat dissipation structures and vents to ensure that electronic components can operate stably within a safe operating temperature range. In addition, designers can also use thermal simulation software to simulate and optimize the heat distribution and heat dissipation effect of the circuit board, improve heat dissipation efficiency and extend the service life of electronic components.

In the design process, CAD software plays a vital role. Designers can use CAD software to conduct accurate three-dimensional modeling and simulation analysis to quickly verify the feasibility of design solutions and identify potential problems. CAD software can also provide a wealth of design tools and library files to help designers quickly draw circuit layouts and internal cavity structures, and generate detailed manufacturing files and drawings to provide support for subsequent manufacturing and assembly.

In summary, designing an embedded cavity PCB board requires comprehensive consideration of multiple factors such as internal cavity structure, circuit layout, and thermal management, and precise design and simulation verification with the help of CAD software to ensure that the final product has good performance and reliability.

What is the manufacturing process of embedded cavity PCB board?

Manufacturing embedded cavity PCB boards is a complex and precise process that involves multiple key steps, each of which requires strict process control and precision processing equipment. The specific process of manufacturing embedded cavity PCB boards will be introduced in detail below.

The first step in manufacturing an embedded cavity PCB board is to choose the appropriate material. Commonly used materials include substrate materials, conductor materials, insulating materials, etc. The substrate material is usually selected with good electrical properties and mechanical strength, such as FR-4 fiberglass composite. The conductor material can be selected from materials with good electrical conductivity such as copper or aluminum. Insulating materials are used to fill the internal cavity, usually materials with good insulation properties and heat resistance are chosen.

The core of manufacturing embedded cavity PCB board is the processing of internal cavity. This step requires precision processing equipment and process control. First, according to the design requirements, the internal cavity is processed on the substrate. Common processing methods include CNC machine tool processing, laser cutting, etc. During the processing process, it is necessary to ensure that the size and shape of the internal cavity meet the design requirements, while ensuring the flatness and accuracy of the processed surface.

After finishing the internal cavity, next is the printed circuit layer. This step requires printing the conductor pattern on the surface of the substrate and connecting it to the internal cavity. Printed circuit layers usually use photolithography or screen printing processes. In the photolithography process, photoresist is first coated on the surface of the substrate, and then conductor patterns are formed through steps such as exposure and etching. In the screen printing process, conductive ink is printed on the surface of the substrate through screen printing to form a conductor pattern.

After completing the printed circuit layer, chemical etching is required. Chemical etching is the process of etching away unwanted metal materials from the surface of a substrate to form the desired conductor pattern. The etching solution is usually a solution containing chemicals such as ferric chloride or hydrogen peroxide. The etching time and temperature need to be strictly controlled during the etching process to ensure the accuracy and uniformity of etching.

The final step is to assemble the electronic components onto the PCB board. This includes soldering components, connecting wiring, performing functional tests, etc. The assembly process requires precision welding equipment and professional operating techniques to ensure the accuracy of component installation and the reliability of connections.

To sum up, the process of manufacturing embedded cavity PCB boards includes multiple key steps such as material selection, internal cavity processing, printed circuit layering, chemical etching and assembly. Each step requires precise process control and strict quality management to ensure the performance and reliability of the final product.

How much does an embedded cavity PCB board cost?

The cost of embedded cavity PCB board is a complex and changeable issue, which is affected by many factors. Before estimating costs, there are several key factors that need to be fully considered:

Material selection: The choice of panels has a huge impact on cost. Common PCB boards include FR-4, high-frequency materials, metal substrates, etc. Different materials have different performance characteristics and price levels, so there is a trade-off between performance and cost when choosing a material.

Processing technology: The processing technology of PCB directly affects the cost. Precision processing technology usually requires higher cost investment, such as multi-layer board processing, internal cavity processing, etc. In addition, the use of special processes (such as blind vias, buried vias, etc.) will also increase manufacturing costs.

Component cost: The component cost on the PCB board is also an important part of the overall cost. The type, brand, specifications, etc. of components will all affect the cost. Some high-performance components are more expensive, while low-cost components may affect product performance and reliability.

Process optimization: Costs can be reduced by optimizing design and processing technology. For example, rational layout of circuit components can reduce board area and material waste, and using efficient processing technology can improve production efficiency and reduce scrap rates, thereby reducing overall costs.

Mass production scale: Cost is also affected by mass production scale. Typically, high-volume production can enjoy lower costs because production lines can be optimized and raw materials purchased in bulk, thereby reducing unit costs.

Therefore, estimating the cost of embedded cavity PCB boards requires comprehensive consideration of the above factors and reasonable optimization and trade-offs. Through reasonable selection of materials, optimized design, and precise management of the production process, costs can be effectively controlled and product competitiveness improved.

What are the material choices for embedded cavity PCB boards?

The material selection of embedded cavity PCB board is crucial because it directly affects the performance, stability and application range of the circuit board. Typically, manufacturers select the appropriate materials based on specific application needs. The following are some common embedded cavity PCB board materials:

FR-4 is a fiberglass reinforced epoxy resin material and one of the most common PCB board materials. It has excellent electrical properties, mechanical strength and heat resistance, making it suitable for most general electronic applications. In embedded cavity PCB boards, FR-4 materials can provide good circuit insulation and mechanical support, and also have high heat resistance, which is suitable for meeting a certain degree of thermal management needs.

For embedded cavity PCB boards that need to process high-frequency signals, high-frequency materials such as PTFE (polytetrafluoroethylene) or PP (polypropylene) are usually used. These materials have low loss and low dielectric constant, which can effectively reduce loss and attenuation during signal transmission and ensure the stability and reliability of the circuit.

Metal substrate is a PCB board material that covers copper foil on a metal base. It has excellent heat dissipation performance and can effectively conduct heat to the external environment, thereby improving the thermal management capabilities of the circuit board. In some embedded cavity PCB applications with high power density or higher performance requirements, metal substrates are an ideal choice.

In addition to the common materials mentioned above, there are also some special materials to choose from, such as polyimide (PI), polyetheretherketone (PEEK), etc. These materials have special properties, such as high temperature resistance and corrosion resistance, and are suitable for embedded cavity PCB applications in some extreme environments.

When selecting materials, manufacturers need to consider factors such as circuit layout, environmental conditions, performance requirements, and cost. Through reasonable selection of materials, the embedded cavity PCB board can be ensured to have good electrical properties, mechanical properties and thermal management properties to meet the needs of various applications.
