Frequently Asked Questions
Alumina Nitride (AlN) provides significantly higher thermal conductivity (roughly 5 times that of Al2O3) and a thermal expansion coefficient that closely matches silicon, reducing mechanical stress and preventing component failure in high-power applications.
They are primarily used in high-power semiconductor modules, aerospace and military electronics, RF power control circuits, laser industrial electronics, and automotive power systems.
Yes, due to its excellent electrical resistance and thermal management capabilities, AlN is ideal for high-frequency switching power supplies and RF power hybrid circuits.
Immersion Gold (with thickness >= 3UM) provides superior solderability, excellent corrosion resistance, and a flat surface for precise component mounting, which is critical for high-reliability electronics.
While our standard model is 0.635mm, we specialize in custom electronic component manufacturing and can discuss specific substrate requirements based on your thermal design needs.
AlN handles thermal cycling exceptionally well because its Coefficient of Thermal Expansion (CTE) is similar to that of the semiconductor chips mounted on it, minimizing the risk of cracking or detachment during temperature swings.

A truck wire harness is like the nervous system of a truck. It is a group of wires, connectors, and terminals that link all the electrical parts together.
Modern Printed Circuit Boards (PCBs) are no longer limited to performing simple electrical connections.
As electronic products continue to evolve, standard circuit boards are often no longer sufficient to meet increasingly complex functional requirements.
As electronic products become smaller, faster, and more feature-rich, PCB technology has evolved to accommodate increasingly complex circuit designs.
