Introduction Ceramic-to-metal hermetic seals often pass helium leak testing at shipment but develop leakage after thermal cycling or long-term service. In most cases, multiple interface defects—not a single process issue—drive this failure through gradual degradation under thermal stress and material
Three Critical Interfaces in Ceramic-to-Metal Hermetic Seals Keep Reading »
Introduction As a premier manufacturer specializing in components like the ceramic conical burr, we understand that reliability is paramount. In pepper mills, coffee grinders, and other small kitchen appliances, ceramic burrs have become a mainstream choice due to their high

Introduction With the widespread adoption of 800V high-voltage platforms and SiC power devices, electric vehicle (EV) power modules are facing higher thermal loads, more stringent thermal cycling, and higher reliability requirements. Traditional alumina (Al2O3) substrates are still widely used due
Why EV Power Modules Are Increasingly Using Silicon Nitride Substrates Keep Reading »
Introduction Customers often ask, “Which is better, alumina or zirconia?” “What is the difference between silicon carbide and silicon nitride?” or “Which type of wear-resistant ceramic should I choose?” In reality, no single material is a one-size-fits-all solution. If we
