Selection priorities by market
The Same Property Can Mean Something Different in Every System
Use these profiles to frame the first engineering conversation. They highlight the operating context behind the material choice, not a universal specification.
EV Batteries and Stationary Energy Storage
Large interfaces, module tolerance and long service life make mechanical compliance and dispensing consistency central. A material may need to transfer heat between cells or modules and a cold plate while also supporting electrical isolation, vibration durability and automated assembly. The real design range—not only the nominal gap—should drive the first shortlist.
- Map first
- Cell/module geometry, cold-plate flatness and gap distribution
- Validate
- Thermal cycling, vibration, dielectric behavior and flame targets
パワーエレクトロニクス
IGBTs, MOSFETs, converters and inverter modules can combine high heat flux with high voltage and repetitive power cycling. The interface must work under the actual mounting pressure and surface condition. Electrical insulation, thickness tolerance and stability over cycling can outweigh a small difference in headline conductivity.
- Map first
- Junction-to-case-to-sink path and clamping method
- Validate
- Thermal impedance, dielectric strength and power-cycle durability
Data Centers and AI Servers
Accelerators place dense heat sources close to HBM, VRMs and high-speed networking components. Interfaces may be thin but mechanically sensitive, with tight pressure budgets and strong serviceability expectations. A useful comparison recreates the real cold-plate flatness, fastener pattern, vertical orientation and temperature cycle instead of testing a material in isolation.
- Map first
- GPU/HBM height variation, cold plate and pressure distribution
- Validate
- Pump-out, contact resistance, aging and rework
通信・5G機器
Outdoor AAUs, RRUs and power amplifiers operate continuously through weather, solar load and wide temperature swings. Enclosure gaps can be irregular, and maintenance intervals may be long. Material selection should pair thermal performance with sealing strategy, compression retention, corrosion awareness and resistance to repeated hot-cold exposure.
- Map first
- Radio, amplifier and enclosure conduction paths
- Validate
- Outdoor aging, thermal cycling and compression set
Semiconductor and Electronics Assembly
Fine-pitch packages and compact assemblies often need underfill, corner bonding, coating or encapsulation rather than only a conventional TIM. Flow behavior, substrate wetting, cure shadow, ionic cleanliness and stress after cure all affect reliability. The dispense path and cure profile should be treated as part of the material specification.
- Map first
- Package geometry, keep-out zones and substrate surfaces
- Validate
- Flow, cure, adhesion, CTE stress and contamination
車載電子機器
ADAS, ECU, infotainment and power modules combine compact packaging with vibration, temperature cycling and long qualification horizons. Production traceability and process repeatability matter as much as an initial thermal result. Material changes should be assessed against the whole reliability plan and the specific substrate and surface-treatment combination.
- Map first
- Module location, interfaces, mounting and exposure
- Validate
- Automotive cycling, vibration, humidity and process controls
LED照明
LED boards, drivers and housings need stable heat transfer to protect lumen output and lifetime. Thin interfaces can benefit from grease, pads or adhesive systems depending on assembly method and service needs. Outdoor products add moisture, UV and temperature exposure; optical areas may also make contamination and volatile control important.
- Map first
- LED board-to-housing path and driver hot spots
- Validate
- Thermal aging, dielectric performance and outdoor exposure
産業用電子機器
Motor drives, PLCs, sensors and control power supplies see varied duty cycles and environments. Dust, oils, vibration or limited airflow may drive the need for sealing or encapsulation alongside thermal management. Repair strategy matters: a fully potted assembly behaves very differently in production and service from a coated or locally bonded design.
- Map first
- Duty cycle, enclosure, airflow and service approach
- Validate
- Chemical exposure, shock, vibration and field temperature
家電製品
Laptops, gaming systems and mobile devices compress multiple hot components into thin enclosures. Low bond-line thickness, placement speed, feel, acoustic behavior and rework can all influence the choice. Testing should represent device orientation and repeated user heat cycles, especially where grease migration or pad compression can change over time.
- Map first
- Stack height, enclosure flex, component tolerance and touch points
- Validate
- Drop, cycling, migration, compression and repair

Questions Before You Shortlist a Material
Good selection begins with the full interface and process—not a single headline property.
Which thermal material is best for a large or uneven gap?
Soft thermal pads and dispensable gap fillers are common starting points. Pads offer controlled thickness and clean placement; liquid gap fillers better accommodate complex geometries and can reduce stress when dispensed and cured correctly.
熱伝導率は高ければ高いほど常に良いのでしょうか？
No. Effective performance depends on bond-line thickness, wet-out, contact resistance, assembly pressure and long-term stability. A lower-conductivity material with better contact can outperform a higher-rated but poorly fitted option.
When should I choose a pad instead of grease or gel?
Choose a pad when handling, controlled thickness, electrical isolation or die-cut geometry is important. Grease is useful for very thin interfaces and low contact resistance. Gel or liquid gap filler is useful for variable gaps, complex surfaces and low assembly stress.
Can a thermal material also provide structural bonding?
Yes. Thermally conductive adhesives can combine heat transfer with fixation, but strength, modulus, cure conditions, rework and thermal cycling must be evaluated together.
What information is needed for a material recommendation?
Share the substrates, interface area, nominal and maximum gap, operating temperatures, pressure, thermal target, electrical isolation need, dispensing or placement process, cure constraints, reliability tests and expected volume.
Can Haktak customize thickness, shape, hardness or formulation?
Application development can include material selection, formulation changes, die-cut geometry, dispensing support, testing and prototype samples. Feasibility depends on the target properties, process and production volume.
