Frequently Asked Questions
How do I choose between heat dissipation, heating and TEC cooling?
Define the thermal function first. If the system must remove heat, consider substrates or heat spreaders. If it must generate heat, consider AlN or alumina ceramic heaters. If it must stabilize temperature below ambient or tightly control a laser/detector, TEC ceramic substrates may be required.
Why is AlN widely used in thermal management?
AlN combines high thermal conductivity with electrical insulation, making it useful for power electronics, laser packages and ceramic heaters where heat transfer and dielectric isolation are both required.
When is alumina still a good choice?
Alumina is suitable when cost, dielectric strength, production maturity and mechanical stability are more important than maximum thermal conductivity.
What information is needed for a thermal management RFQ?
Please provide drawings, heat load or required heater power, target temperature, voltage, dimensions, environment, mounting method, quantity and reliability requirements.
Can ceramic parts be metallized or assembled with metal parts?
Yes. Depending on the design, metallization, plating, brazing, electrodes and ceramic-to-metal assemblies can be reviewed as part of the solution.
Do you support custom ceramic thermal components?
Yes. Custom substrates, heaters, insulating plates, heat spreaders and TEC ceramic parts can be evaluated based on drawings and application conditions.
