datacenter photo/laptop with thermal pad
In many modern electronic assemblies—especially those involving precision imaging systems, smart sensors, and consumer electronics—designers need a thermal interface material that performs well even under low pressure while remaining flexible, compliant, and electrically insulating. Leader Tech’s TGF30 thermal gap filler is engineered exactly for these environments.
At NEDC, we produce custom die-cut TGF30 pads that fit seamlessly into tight mechanical envelopes, helping engineers address thermal bottlenecks without redesigning their hardware.
What Is TGF30?
TGF30 is a silicone-based thermal interface material pad known for:
-
High flexibility
-
Strong insulation characteristics
-
Excellent aging resistance
What makes TGF30 stand out is its ability to maintain stable thermal performance even when only minimal compression force is available—making it a strong choice for delicate or lightweight assemblies where clamping force is limited.
Key Features
TGF30 provides a balanced thermal and mechanical profile:
-
Low thermal impedance
-
Effective performance under low pressure
-
Excellent compression characteristics
-
High elasticity and mechanical strength
-
Thermal conductivity around 3.0 W/m·K
-
Wide operating temperature range: –50°C to +180°C
-
Shore 00 hardness between 15–75 depending on thickness
-
UL94 V-0 / 5V rating for flame resistance
Its bright blue color also helps visually differentiate it from other thermal interface materials during assembly.
Typical Applications
TGF30 is used extensively in:
-
Optoelectronic systems
(high-sensitivity detectors, high-definition imaging modules) -
Consumer devices and household appliances
-
Vehicle electronics
-
Wireless communication hardware
(5G modules, radio boards, broadband equipment)
Its softness, tack, and low-pressure performance make it ideal for areas where components cannot tolerate excessive compressive stress.
Electrical Performance
Beyond thermal conduction, TGF30 contributes to electrical safety and signal integrity through:
-
Breakdown voltage of 8 kV/mm or higher
-
High volume resistivity
-
Stable dielectric constant
-
Low dielectric loss
This combination ensures reliable isolation in mixed-signal, RF, and power-dense assemblies.
How NEDC Supports TGF30
NEDC converts TGF30 into precision die-cut thermal pads that fit your exact design requirements. Whether the design calls for thin profiles (as low as 0.3 mm) or thicker pads up to 18 mm, we produce production-ready parts tailored to your drawings.
Our capabilities ensure:
-
Tight dimensional accuracy
-
Consistent repeatability
-
Clean edges and easy placement in assemblies
-
Support for prototypes, small runs, and full production volumes
Customers rely on NEDC because thermal pads rarely come in a one-size-fits-all format—our converting ensures TGF30 fits the hardware instead of forcing the hardware to fit the pad.
Storage & Shelf Life
Leader Tech recommends storing TGF30 in the dark, under 30°C, at less than 70% humidity. Under proper storage conditions, the material offers a two-year shelf life.
Conclusion
TGF30 fills a specific and important role in thermal management: an electrically insulating, compliant, low-pressure thermal interface material built for sensitive and high-end electronics. Its mechanical flexibility and strong insulation properties make it especially useful in imaging systems, communications hardware, and compact consumer devices.
With NEDC’s custom die-cutting, integrating TGF30 into your design becomes straightforward, scalable, and highly repeatable.
