Product Overview
Our metallized ceramic circuit boards are manufactured from 99.9% high-purity polished aluminum nitride (AlN). Each substrate undergoes rigorous inspection for surface roughness, flatness, and mechanical stability. Using advanced magnetron sputtering combined with laser trimming technology, we produce planar platinum resistors with excellent reliability. These resistors can replace imported products and, in some applications, provide a cost-effective alternative to NTC thermistors.
