Electrical Applications
Ceramic insulators · bushings · high-voltage standoffs
Advanced ceramics combine strong dielectric strength with thermal stability and long-term reliability, which is why ceramic insulators and bushings are the standard choice in transformers, switchgear, and power distribution equipment — improving insulation performance, operational safety, and service life.
We machine insulators and bushings in high-purity alumina to your voltage class, profile, and mounting dimensions, whether for power transmission hardware, electronic packaging, or sensing equipment.
Electronic Applications
Ceramic substrates · DBC construction · AMB construction
Electronic packaging and power modules depend on a substrate that can insulate a high-voltage circuit while pulling heat away from the die underneath it. Alumina and aluminum nitride substrates — including DBC (Direct Bonded Copper) and AMB (Active Metal Brazing) constructions — do both at once, which is why they're the standard base for IGBT modules, inverters, and LED packaging.
We machine and metallize substrates to your circuit layout and thermal requirements, in the material and thickness your power budget calls for.
Semiconductor-Grade Components
Need Electrostatic Chucks, Vacuum Components, or Plasma-Resistant Parts?
Wafer fabrication and semiconductor equipment call for a different tier of precision — contamination control, cleanroom-compatible packaging, and tolerances held to ±0.01mm. We cover that in full depth, with dedicated components and specs, on our Semiconductor Ceramic Components page.

Frequently Asked Questions
Why are advanced ceramics widely used in electrical and electronic systems?
Ceramics combine strong electrical insulation with high thermal conductivity and heat resistance, so they can carry away heat from a power device while keeping conductors safely isolated — something metals and plastics can't do at the same time. That makes them the default choice for high-voltage systems, power electronics, and semiconductor equipment.
Which ceramic materials are commonly used in electronics manufacturing?
High-purity alumina and aluminum nitride are the two workhorses. Alumina offers strong general-purpose insulation at lower cost; aluminum nitride adds much higher thermal conductivity (140–180 W/m·K) for parts that also need to move heat away from a power device.
How do ceramic substrates improve power electronic device performance?
A DBC or AMB ceramic substrate spreads heat away from the die faster than a standard PCB, which lets the device run cooler at the same power level — or the same temperature at higher power. It also keeps the high-voltage circuit electrically isolated from the heat sink and enclosure.
Do you supply ceramic insulators and bushings for power transmission equipment?
Can you produce custom DBC or AMB substrates to our specification?
Yes. Send your circuit layout, material (alumina or AlN), and thickness requirements, and our engineering team will return a manufacturing quote, typically within 24 hours.
