Features and Benefits
• Thermal impedance:
• Will not drip or run like grease
• Phase change compound coated on
Hi-Flow 300G consists of a thermally conductive
55°C phase change compound coated on a
fiberglass web. Hi-Flow 300G is designed as a
thermal interface material between a computer
processor and a heat sink.
Above the phase change temperature,
Hi-Flow 300G wets-out the thermal interface
surfaces and flows to produce low thermal
impedance.The material requires pressure of
the assembly to cause flow. Hi-Flow 300G will
not drip or run like grease.
Application Methods
1. Hand-apply to 40°- 50°C heat sink.The heat
2. Hand-apply to 20°- 35°C heat sink.
3. Automated equipment with 30 psi pressure.

0.20°C-in
a fiberglass carrier
sink is heated in an oven or by a heat gun
to between 40°- 50°C allowing the Hi-Flow
300G pad to be applied like an adhesive
pad.The heat sink is then cooled to room
temperature and packaged.
Hi-Flow 300G can be applied to a room
temperature heat sink with the assistance
of a foam roller.The pad is positioned on
the heat sink and a hand roller is used to
apply pressure of 30 psi.
A pick-and-place automated dispensing unit
can be used to apply Hi-Flow 300G to a
room temperature heat sink.The placement
head should have a soft silicone rubber
pad, and apply 30 psi pressure to the pad
on transfer to the 20°- 35°C heat sink.

THERMAL PERFORMANCE vs PRESSURE
1) This is the measured thermal conductivity of the Hi-Flow coating. It represents one conducting layer in a three-layer laminate.The
Hi-Flow coatings are phase change compounds.These layers will respond to heat and pressure induced stresses.The overall conductivity
of the material in post-phase change, thin film products is highly dependent upon the heat and pressure applied.This characteristic is
not accounted for in ASTM D5470. Please contact Bergquist Product Management if additional specifications are required.
2) The ASTM D5470 (Bergquist modified) test fixture was used and the test sample was conditioned at 70°C prior to test.The
recorded value includes interfacial thermal resistance.These values are provided for reference only. Actual application performance is
directly related to the surface roughness, flatness and pressure applied.
