Finding Your Solution

Aavid cooling offerings will work with any type or brand of FPGA as long as you match the correct system requirements with the thermal technology. Due to the number of options and combinations, Aavid recommends that you fill out the FPGA Solution Questionnaire as thoroughly as possible to be able to match solutions to your needs.

Key factors to choosing or creating the proper solution:

  • Power Levels/ Watts
  • Available Space / Solution Size Requirements
  • Attachment Type
  • Forced or Natural Convection
 

FINDING YOUR FPGA THERMAL SOLUTION – Requirements Questionnaire

  1. Provide a data sheet, if possible. At a minimum, provide the footprint. 
  2. What are the size constraints for the heat sink (Maximum in mm)?  
  3. Where will the device be located on the heat sink base? Please provide a sketch if available.
  4. How much power (Watts) will be dissipated from the device? 
  5.  Describe the ambient conditions: 
    1. Are you open to use a fan for cooling? If so, what is the air velocity (CFM)? 
    2. Will the heat sink be fully ducted (no extra space between the heat sink edges and the duct)? If not, please describe.
    3. If you do not plan on using a fan, what will the orientation of the heat sink be with respect to gravity? 
  6. What is the maximum allowable case temperature of the device? NOTE: If you do not specify a max case temp, then the heat sink will be designed around the max junction temp listed on the data sheet.
  7. Does the device need to be electrically isolated from the heat sink? If so, what dielectric strength is required?
  8. What will be used as the interface material between the device and heat sink?NOTE: Aavid can recommend and include an interface material as part of the completed assembly
  9. What is the preferred method of mounting the device to the heat sink?EXAMPLES: double sided tape, PCB attach, attach to device etc…
  10. What finish do you need on the heat sink?

Heat Pipe Assemblies

Aavid is a world leader for heat pipe technology and design for extremely efficient passive cooling.

Heat pipes have many advantages and applications in thermal solutions. Heat pipes transport significant amounts of heat without a large increase in temperature, but do not dissipate any heat out of the system by themselves.

This unique transfer capability allows heat pipes to transport or spread heat to a point remote from the heat generator. Integrating a heat pipe into a system can open new thermal solutions to systems with high density power loads, enclosed or limited space, weight restrictions, or limited airflow.

The availability of a wide range of heat pipes sizes and power handling capabilities make them suitable for integration in heat sinks for 50W processors to multi kilowatt IGBTs.
