The cost of the microcavity substrate is one of the key factors to be considered in the manufacturing process. It directly affects the competitiveness and market positioning of the product. Understanding the factors that influence microcavity substrate cost and how to optimize cost in terms of materials and design is one of the challenges that manufacturers must face.

First, the cost of microcavity substrates is affected by many factors. Among them, material selection is one of the most important factors. Different substrate materials have different physical properties and manufacturing difficulties, so their costs will also vary. High-performance specialty materials may result in higher costs, while general-purpose materials are relatively cheaper.

Secondly, design complexity and manufacturing process are also important factors affecting the cost of microcavity substrates. Complex designs and special manufacturing processes often increase production costs because they require more time and resources to complete.

What materials are used for microcavity substrates?

The material selection of the microcavity substrate is crucial, as it directly affects the performance, stability and application range of the microcavity substrate. Common microcavity substrate materials include ceramics, FR-4, and flexible materials such as polyimide. Each material has unique characteristics and is suitable for different application scenarios.

First, ceramic is a common microcavity substrate material with excellent thermal conductivity and high temperature resistance. Ceramic substrates can effectively dissipate heat and therefore perform well in high power density and high temperature environments. In addition, ceramic substrates have good mechanical strength and chemical stability, making them suitable for harsh industrial and military applications.

Secondly, FR-4 is a commonly used substrate material with good mechanical and electrical properties. FR-4 substrate is cheap and easy to process, and is widely used in consumer electronics and general electronic equipment. However, the thermal conductivity of FR-4 substrate is relatively poor and is not suitable for applications in high-power or high-temperature environments.

In addition, flexible materials such as polyimide (PI) substrates have excellent flexibility and bending properties and are suitable for curved displays, flexible electronic products and other fields. PI substrate has excellent high temperature resistance and chemical stability, but its cost is higher compared to ceramics and FR-4.

In addition to the common materials mentioned above, there are other special materials, such as metal substrates, aluminum substrates, etc., which have specific characteristics and are suitable for specific application scenarios. Metal substrates have excellent thermal conductivity and are suitable for applications that require efficient heat dissipation, while aluminum substrates have the advantages of being lightweight and low-cost, and are suitable for applications that are sensitive to weight and cost requirements.
