Thermal Gap Pads – Our Precision Die-Cutting Solutions
Our Die-Cutting Equipment
Our Thermal Gap Pads are manufactured in a Class 1000 cleanroom environment to ensure consistent thermal performance and surface cleanliness. Automatic roll-to-roll lamination machines apply thermal interface materials with high precision, avoiding air gaps that could reduce heat transfer efficiency.
The automatic lamination waste removal machines streamline production by removing excess materials cleanly, maintaining pad integrity and preventing contamination. This is crucial for ensuring the pads fit precisely into thermal management assemblies.
High-precision die-cutting machines are used to shape Thermal Gap Pads to exact specifications, achieving tolerances of ±0.01mm. This guarantees that each pad aligns perfectly with components such as processors, battery packs, and heat sinks.
Our Die-Cutting Quality Control
Dimensional accuracy is validated with 2.5D measurement systems, while CCD and binocular microscopes inspect for surface defects that could impair thermal conductivity. Dust particle counters maintain optimal cleanroom air quality to avoid introducing contaminants.
Peel strength testers ensure adhesive-backed pads maintain reliable bonding, and thickness gauges confirm consistent pad thickness for even thermal contact. Environmental test chambers simulate extreme temperature and humidity conditions to verify long-term performance stability.
Electrical resistance testers are used when pads have insulating properties, ensuring that Thermal Gap Pads maintain electrical isolation where required. Our IPQC process ensures consistent quality monitoring throughout production.
Our Inspection Team
Our dedicated inspection team operates in a Class 1000 cleanroom, performing final product verification to ensure every Thermal Gap Pad meets precise dimensional, cleanliness, and performance standards before delivery.
Our Mold Management
Our in-house mold department designs, produces, and maintains precision cutting tools for Thermal Gap Pads using CAD software, CNC machining, and laser cutting. Regular calibration and maintenance guarantee that every production run meets exact specifications.
Our Product Cases
One example is the dust-proof mesh and gasket rings used in mobile devices to block dust from entering speakers and microphones while maintaining sound clarity. Produced in a cleanroom with precision die-cutting, they meet strict airflow and tolerance requirements.
Another case is foam gaskets for smartphone camera modules, preventing dust intrusion and light leakage. Automated lamination ensures precise adhesive application, while die-cutting achieves complex shapes without compromising structural integrity.
A third example is PET or PC sheets with protective films, used in applications like screen protection, insulation, and anti-scratch layers. These undergo rigorous dimensional inspections, surface defect checks, and durability testing to ensure long-lasting performance.

The Thermal Conductivity Of Thermal Gap Pads Varies Depending On The Material And Type Of Product.
For Standard Thermal Silicone Pads, The Thermal Conductivity Is Usually Around 1.0-3.0W/m·K.
High Thermal Conductivity Silicone Pads Have A Conductivity Range Of 1.5-3.0W/m·K.
Some Special Products, Like BERGQUIST® GAP PAD TGP 10000ULM, Can Reach 10.0W/m·K.
Other Variants Like THERM-A-GAP PAD 30 Offer 3.2W/m·K, While THERM-A-GAP PAD 80 Has 8.3W/m·K, And THERM-A-GAP PAD 70TP Has 7.0W/m·K.
In General, The Thermal Conductivity Of Thermal Gap Pads Ranges From 1W/m·K To Over 10W/m·K, Depending On The Product And Material Type.
The Temperature Range For Thermal Gap Pads Varies Depending On The Material Type.
For Standard Silicone Rubber Pads, They Can Be Used Continuously Between -60°C And +200°C, With Short Peaks Up To +250°C.
Solid Silicone Rubber Pads Have A Similar Range, From -60°C To +200°C, But Can Handle Short Spikes Up To +300°C.

The Ability Of Thermal Gap Pads To Support Heavy Loads Depends On Their Material Properties And Design. Here Are Some Key Points To Consider.
Thermal Gap Pads Have Flexibility And Compressibility, Allowing Them To Fit Well Between Power Devices And Heat Sinks Or Enclosures, Which Helps With Efficient Heat Transfer.
Their Tear Strength Indicates How Well The Material Can Handle Stress And Repeated Disassembly, Typically Ranging From 0.4 To 0.6 kN/m. Stronger Options Should Be Chosen For Higher Loads.
The Hardness And Density Of The Pad Vary, With Shore Hardness Typically Ranging From 30 To 80. Pads With Lower Hardness Are Preferable To Minimise Pressure During Compression.
Tear Strength Measures The Maximum Force Required To Tear The Pad Along A Cut. This Reflects The Pad’s Durability And Ability To Withstand Stress Without Failing.
Compression Set Shows How Well A Pad Recovers After Being Compressed. Pads Made From Domestic Materials May Experience A Compression Set Of 40% To 65%, So They Are Not Recommended For Repeated Use.
If The Thermal Pad Is Thin (Under 1mm) Or Used In High-Pressure Areas, Adding Reinforcement Materials Like PI Film Or Silicone Fabric (With Glass Fibres) Can Enhance Its Strength.
In Conclusion, Whether A Thermal Gap Pad Can Support Heavy Loads Depends On The Specific Application And Product Specifications. In Some Cases, Reinforced Materials Are Needed To Improve Strength.
The Storage Conditions For Thermal Gap Pads Are Quite Important To Maintain Their Performance. Here Are Some Key Points:
