Against the backdrop of the rapid development of AI chips, the explosive growth of AI computing power is driving a sharp increase in the demand for ceramic substrates (especially high thermal conductivity aluminum nitride, silicon nitride, etc.), making them one of the key materials for heat dissipation in AI chips. Ceramic substrates have become a “must-have” material for solving the heat dissipation bottleneck of computing power chips, and have become an “invisible must-have” and heat dissipation savior in the era of AI computing power. Ceramic substrate cutting discs (scribing/cutting processing stage) also benefit accordingly.
Ceramic substrate cutting discs mainly refer to diamond Dicing blades, cutting wheels or processed ceramic cutting discs used for precise cutting/slicing of ceramic substrates (such as alumina Al₂O₃, aluminum nitride AlN, silicon nitride Si₃N₄, etc.). In high-power scenarios such as AI chips and optical modules, the demand for ceramic substrates has soared, directly driving the growth of cutting consumables and processing services.
The high hardness and brittleness of ceramic substrates make precise cutting/scribing a key bottleneck in the manufacturing process. MORESUPERHARD ceramic substrate cutting blades (diamond Dicing blades /Dicing blades), with their ultra-high precision, low chipping and long service life, serving as the “invisible enabler” behind AI hardware production.
Superior Thermal Management: AI GPUs generate massive heat. AlN ceramics offer thermal conductivity of 170–230 W/m·K, far exceeding traditional PCBs, ensuring stable operation under extreme computing loads.
High Reliability: Excellent electrical insulation, mechanical support, and matched coefficient of thermal expansion (CTE) for reliable high-density packaging and complex 3D structures.
Strong Market Growth: The ceramic substrate sector is in a high-growth phase, driven by AI infrastructure, optical communications, and new energy applications. HTCC ceramic substrate demand continues to expand rapidly.
Ceramic dicing requires simultaneous excellence in micron-level precision, low damage (minimal micro-cracks and chipping), and high efficiency. MORESUPERHARD’s specialized diamond dicing blades are engineered for exactly these needs:
Exceptional sharpness and self-sharpening properties. Ideal for thicker ceramic substrates, QFN packages, glass, and other hard & brittle materials. Delivers outstanding cut quality and long service life.
Ultra-thin design (thickness as low as 0.03–0.3 mm), narrow kerf, and superior edge quality. Specifically optimized for semiconductor packaging substrates, ceramic LED substrates, AI high-thermal-conductivity ceramics, PZT, and similar materials.
Wide Material Compatibility: Proven performance on AlN, Si₃N₄, Al₂O₃, SiC, and other advanced ceramics.
AI Server GPU Ceramic substrate (the most core)
• Materials: Aluminum oxide (Al₂O₃), aluminum nitride (AlN) (high thermal conductivity, suitable for cooling kilowatt-level Gpus).
Ceramic substrate for optical modules
• Materials: Alumina, LTCC low-temperature co-fired ceramics (insulating, high-frequency compatible).
Power semiconductor (IGBT/SiC) ceramic substrate
• Materials: AlN, SiC ceramics (high thermal conductivity, thermal shock resistance).
Ceramic substrate for AI sensors/RF modules
• Materials: Alumina, zirconia (high insulation, high-frequency stability).
Ceramic substrates are prone to thermal stress, cracking, and edge defects during cutting. MORESUPERHARD overcomes these through:
Optimized bond systems and uniform diamond distribution to minimize cutting stress and prevent fractures.
Reduced heat-affected zones and superior edge quality for higher final product reliability.
Support for hybrid laser + mechanical processes, offering comprehensive cutting solutions.
In 2026 and beyond, AI compute power, 5G/6G optical modules, and SiC/GaN devices will drive explosive demand for high-precision ceramic substrates. MORESUPERHARD, a professional superabrasive tool manufacturer with years of experience, provides cost-effective, high-reliability dicing solutions that help domestic leaders (such as Sanring, China Porcelain Electronics, and others) accelerate mass production and technological upgrades.
