Power Dissipation Heat Sink-FAQ's
What materials do you use for power dissipation heat sinks?
We primarily use 6063-T5 aluminum for its balance of thermal performance and extrusion capability. Copper can be used for higher conductivity.
Can I customize the fin geometry?
Yes, we offer fully customizable fin height, thickness, spacing, and base size to meet your power dissipation needs.
Do you support anodizing and surface finishing?
Absolutely. Black anodizing is most common, but other finishes are also available upon request.
How do you control thermal resistance?
Fin structure and base thickness are engineered to achieve your required °C/W rating under specified airflow conditions.
Are your heat sinks suitable for forced air systems?
Yes, we design heat sinks for both natural and forced convection environments, including fan-integrated setups.
Can mounting holes be included in production?
Yes. We offer CNC drilling, tapping, slotting, and machining for all mounting and interface requirements.
What’s your typical MOQ and lead time?
MOQ is generally 200kg per spec. Lead time is 10-15 working days depending on tooling and order size.
