Micro-faze®

Product Descriptions

MICRO-FAZE is a new, revolutionary thermal interface film formulated with non-silicone thermal grease. It was developed by AOS to offer the lowest thermal resistance in a thermal interface without the mess of grease. MICRO-FAZE does not require burn-in to form into place.

 

 

 

 

Technical Advantages

  • Low thermal resistance with minimum force
  • Naturally tacky, non-silicone
  • Conforms with coefficient of thermal expansion
    (CTE) deficiencies
  • Uniform film and exact thickness of thermal gease
    with each application
  • No phase change required for heat transfer to take place—Good Low Temp Performance
  • Durable resistance over usable lifetime
  • Easily stored at a wide range of temperatures

 

Features and Benefits

  • Retains all the performance advantages of thermal grease but in the form of a thermal pad
  • Requires minimum force to achieve total interface contact
  • Allows for total “wetting action” to fill all micoscopic surface voids without changing phase
  • A positive coefficient of thermal expansion (CTE) deficiencies the wetting action for total interface contact
  • Heat transfer takes place at any temperature (unlike phase change materials), making MICRO-FAZE an excellent choice for cold plate applications
  • Offers maximum heat transfer capability for
    power component
  • Excellent replacement for phase change materials and silicone pads
  • Is a “drop-in-place” product that is easy to use and handle
    in a manufacturing environment
  • Naturally tacky—no adhesive, fiberglass or other
    non-conductive material is used that may penalize
    thermal resistance
  • Microscopically changes to fill all micoscopic voids
    on part surfaces
  • DOES NOT PUMP OUT!

 

Thermal-grease Performance
in a Thermal Pad

MICRO-FAZE perfoms well
at any temperature and minimal pressure

ASTMD 5470-06 thermal resistance values at pressures ranges from
10psi to 100psi

 

 

 

 

Samples After Thermal Shock Stability (0—165˚C @ 10 min Dwell)

 

• MICROFAZE 3A4-52062 after 150 thermal cycles
• Remains tacky with zero pump out

 

 

 

 



• Leading phase-change material after
20 thermal cycles
• Contact lost; dried out

Independent Material Testing

Experiment: Materials tested at different torque values
Summary: Grease performed best; Micro-faze 3 A4 slightly better
than leading Phase Change material

• Actual Thermal Images @ 26 ft-in torque; Equilibrated @ 38 amp, 1.6 volts

THERMAL IMAGING DETAILS

Sample Tested @ several torques and power settings on a 12 pin 44 x 33 mm SiC module
• Max Equilibrium Temperature MF 3A4 and Phase Change; Settings for both = 221oC @ 231 watts
• Initial ΔT’s of 10.7 and 11.2 oC, respectively at 12 in-lb torque

How MICRO-FAZE Works

MICRO-FAZE grease is comparable to leading
CPU grease

 

 

 

 

 

Pad form demonstrates superior resistance to leading CPU thermal grease
