What is the design principle of multi-cavity substrates?

The design of multi-cavity substrates is a complex and precise process involving multiple key principles. Its design principles mainly include the following aspects:

Circuit layout and inter-layer connections: When designing a multi-cavity substrate, the primary considerations are circuit layout and inter-layer connections. Designers need to reasonably arrange the location and layout of circuit components to ensure smooth and stable connections between various cavities, and to minimize signal interference and crosstalk.

Cavity structure design: Multi-cavity substrates usually contain multiple cavities, each cavity is used to package different electronic components or implement specific functional modules. Designers need to reasonably design the structure and size of the cavity based on circuit functions and packaging requirements to ensure that the installation and connection of components can proceed smoothly and will not interfere with each other.

Signal integrity: In multi-cavity substrate designs, ensuring signal integrity is critical. Designers need to consider signal transmission paths, length matching, impedance control and other factors to ensure the stability and reliability of signal transmission.

Thermal management: Electronic components in multi-cavity substrates generate heat when operating, so thermal management is one of the important factors that must be considered in the design. Designers need to rationally arrange the layout and heat dissipation structure of components to ensure that the temperature of the entire system is within an acceptable range and does not affect the performance and life of the components.

Material selection and property matching: In multi-cavity substrate design, choosing the right material is critical to ensure the performance of the entire system. Designers need to select substrate materials, packaging materials, and thermal conductive materials with appropriate characteristics based on the working environment and performance requirements of the circuit to ensure the stability and reliability of the system.

What is the manufacturing process of multi-cavity substrates?

Fabricating multi-cavity substrates is a complex and delicate process involving multiple critical steps, from material preparation to final testing, each step is critical. The specific process of manufacturing multi-cavity substrates will be introduced in detail below.

The first step in fabricating a multi-cavity substrate is to prepare the materials. Usually, the substrate material is FR-4 fiberglass composite material or metal substrate, and the appropriate thickness and size are selected according to the design requirements. In addition, materials required for cavity packaging, such as thermal conductive glue, sealant, etc., need to be prepared.

Design the shape and size of multiple cavities on the substrate material. This step is usually accomplished through processes such as etching or cutting to ensure that the structure and size of the cavity meet the design requirements and can accommodate the intended electronic components.

Next, a circuit layer is printed on the surface of the substrate. Through processes such as photolithography and etching, circuit patterns are printed on the substrate layer by layer, ensuring smooth connections between circuits and good electrical performance.

Pre-selected electronic components are assembled into individual cavities and packaged. This step requires precise operating techniques and professional equipment to ensure that the connection between the component and the substrate is firm and reliable, while ensuring the sealing performance inside the cavity.

The final step in manufacturing multi-cavity substrates is functional testing and quality inspection. By applying specific testing equipment and methods, multi-cavity substrates are comprehensively tested, including testing of electrical performance, thermal conductivity, packaging quality, etc. Only after passing rigorous testing can multi-cavity substrates be delivered for use.

In general, the process of manufacturing multi-cavity substrates includes key steps such as material preparation, cavity design, circuit printing, cavity packaging and final testing. Each step requires precision operations and strict quality control to ensure the performance and reliability of the final product meet design requirements.

There are many factors involved in manufacturing multi-cavity substrates, and their costs will vary accordingly. So, how much does it cost to manufacture a multi-cavity substrate? Let’s explore it together.

First, the cost of manufacturing multi-cavity substrates is affected by the following major factors:

Material cost: The manufacturing of multi-cavity substrates requires the use of special substrate materials and packaging materials. The cost of these materials will directly affect the overall manufacturing cost. The prices of different types of materials vary greatly. For example, metal substrates are more expensive than conventional FR-4 materials.

Manufacturing process complexity: Compared with ordinary printed circuit boards, multi-cavity substrates are more complex in manufacturing process and require more processing steps, such as cavity processing, packaging, etc. These additional processes will increase manufacturing costs.

Design requirements: If the design requirements of the multi-cavity substrate are high, such as cavity dimensional accuracy, inter-layer connection complexity, etc., more process and technical support will be required, thereby increasing manufacturing costs.

Production scale: The scale of producing multi-cavity substrates will also affect the cost. Generally speaking, large-scale production can reduce the manufacturing cost of single boards, while small-scale production is relatively more expensive.

Taking the above factors into consideration, the cost of manufacturing a multi-cavity substrate typically ranges from tens to hundreds of dollars per board. The specific cost will vary based on the actual situation, such as the selected materials, manufacturing process, design requirements, production scale and other factors.

It should be noted that although the cost of manufacturing multi-cavity substrates may be higher, the investment is often worth it compared with the high integration, performance advantages and space efficiency it brings. Therefore, before proceeding with multi-cavity substrate manufacturing, it is recommended to fully evaluate and budget the costs to ensure that the final manufacturing process can be carried out efficiently and economically.
