What types of ceramic packaging substrates are there?
In the field of electronic engineering, ceramic packaging substrates have attracted much attention due to their various types and excellent performance. The following will introduce several common ceramic packaging substrate types and their respective characteristics.
Low-temperature co-fired ceramic packaging substrates are named after their sintering under low-temperature conditions. They usually have good microwave transparency and electrical properties and are suitable for high-frequency communication equipment. In addition, the multi-layer structure of the LTCC substrate makes it very advantageous when integrating complex circuits and components.
High-temperature co-fired ceramic packaging substrates are named because they are sintered at higher temperatures and are usually used in high-temperature environments. They have excellent thermal conductivity and mechanical strength and are suitable for high-temperature applications such as automotive engine control units (ECUs), sensors and power modules.
Thick film ceramic packaging substrates are distinguished by their relatively thick ceramic layers, which provide them with excellent mechanical stability and strong durability. This allows them to withstand harsh working conditions in some industrial sectors, such as aerospace and energy systems.
Compared with thick film substrates, thin film ceramic packaging substrates focus more on achieving high integration on relatively thin substrates. Its advantage lies in lightweight and better heat dissipation performance, which is suitable for some electronic equipment with high weight and heat dissipation requirements.
Multilayer ceramic packaging substrates provide higher integration and design flexibility by stacking multiple thin ceramic layers. They are widely used in complex circuits and radio frequency (RF) applications with excellent signal transmission performance.
The variety of these ceramic packaging substrate types allows engineers to select the most appropriate solution based on specific application needs. Whether in high-frequency communication equipment or applications under extreme operating conditions, ceramic packaging substrates have demonstrated their unique advantages and applicability.
