This product is a 10mm x 10mm 3D Aluminum Nitride (AlN) ceramic packaging substrate specifically designed for high-reliability and high-performance sensor module packaging. Utilizing advanced Direct Plated Copper (DPC) technology with an integrated dam structure, it provides an ideal platform that integrates hermetic protection, thermal management, electrical interconnection, and structural support for various sensitive sensor chips. This substrate is engineered to enhance the long-term stability, signal integrity, and service life of sensor modules operating in harsh environments.
Integrated Dam: The 3D dam structure creates a protected cavity for the sensor chip, enabling hermetic sealing with a metal or glass lid to effectively block moisture, dust, and corrosive gases.
High-Precision Platform: Provides a flat and robust mounting base for sensors like MEMS.
Core Material: The use of high thermal conductivity Aluminum Nitride (AlN) facilitates rapid heat dissipation from the sensor or adjacent components, minimizing thermal gradients and ensuring measurement accuracy and stability.
Matched CTE: Its coefficient of thermal expansion matches that of silicon, significantly reducing thermal stress during cycling and preventing package failure or performance drift.
Fine-Pitch Circuitry: The DPC process enables high-precision, strongly-adhered circuit patterns, meeting the multi-pin, fine-pitch interconnection requirements of sensor chips.
Stable Performance: The ceramic material offers excellent insulation and a low dielectric constant, helping to reduce signal loss and crosstalk, thereby safeguarding the quality of weak signal acquisition.
The ceramic material is resistant to corrosion and radiation. The metallurgical bond between the DPC copper and ceramic ensures robust performance under harsh conditions like high temperature, humidity, and vibration.
This substrate is suitable for various sensor modules with demanding packaging requirements:
MEMS Sensors: Gyroscopes, accelerometers, pressure sensors, microphones.
Optical Sensors: Ambient light sensors, proximity sensors, infrared sensors.
Gas & Chemical Sensors: Modules for industrial monitoring, environmental sensing, and smart homes.
High-Temperature Sensors: For automotive engine compartments and aerospace applications.
Medical Sensors: In implantable or high-precision medical devices.
Q1: What are the unique advantages of this ceramic substrate over traditional plastic or metal packages for sensors?
A1: Traditional plastic packages are permeable to moisture and gas, offering poor long-term reliability. Metal packages can cause electromagnetic interference. This ceramic substrate provides true hermeticity, excellent chemical inertness, thermal stability, and EMI shielding, offering ultimate protection for sensitive sensor chips and ensuring their accuracy and longevity.
Q2: What is the specific function of the dam structure in a sensor module?
A2: The dam serves three primary purposes:
1. Forms a Cavity: Provides space for the sensor chip to move or function.
2. Provides a Sealing Zone: Serves as a bonding area for the lid (metal/glass) to achieve a hermetic seal.
3. Blocks Contaminants: Prevents ingress of contaminants like adhesives into sensitive areas during packaging.
Q3: Is the AlN substrate suitable for temperature-sensitive sensors?
A3: Highly suitable. The exceptional thermal conductivity of AlN helps to rapidly equalize the temperature across the module, eliminating hot spots and providing a more stable, uniform thermal environment for the sensitive chip. This is crucial for minimizing thermal noise and zero-point drift.
Q4: Can passive components be integrated or multi-layer routing be achieved on this substrate?
A4: Yes. The DPC process readily allows for the integration of passive components like resistors and capacitors. While this model has 2 layers, we can provide designs with more layers for more complex interconnections and a higher degree of system integration.
Q5: Is this substrate compatible with wafer-level packaging?
A5: Yes. The DPC process is compatible with wafer-level manufacturing. We can fabricate multiple substrate units on large-format ceramic wafers before dicing, thereby improving production efficiency and reducing cost.
