ディスペンス可能な熱伝導ギャップ充填
電子機器向け液状ギャップフィラーと自動熱材料ディスペンス
Fill uneven component-to-housing gaps with a soft, dispensable thermal interface that wets complex topography, reduces assembly stress and supports scalable production. Select the material together with the gap, bead, equipment, cure and reliability window—not from W/mK alone.
インターフェースの内部
液状ギャップフィラーによる不均一な熱界面の充填
液状ギャップフィラーは, 部品高さや鋳造面の平坦度または組立公差によって直接接触の信頼性を確保できない箇所に使用するディスペンス可能な熱界面材料です. 多くの固体材料よりはるかに低い圧力で形状に追従しながら断熱性の空気を置換します.
変動するギャップ全体の空気を置換
この材料は, 一定厚さの部品では均一に覆えない可能性がある高さのばらつきや表面テクスチャーおよび局所的な空隙に流れ込みます. 最終的なビード体積と圧縮後のボンドライン厚さによって実際に充填されるギャップの大きさが決まります.
Place Material Only Where the Heat Path Needs It
Dots, lines, spirals or programmed paths can cover mixed components without stocking many pad shapes. The process must control shot size, location, wetting and overflow margin.
Reduce Stress on Fragile Components
柔軟なゲルは軽い組立圧力で広がり,有効な熱接触を維持しながらパッケージ,はんだ接合部,基板,セルおよび凹凸のあるモジュールへの荷重を抑えます.

材料選定
1K、後硬化、リワーク可能なサーマルジェルから選択
最適な化学系とは、サンプルシリンジ内で最もシンプルに見えるものではなく、保管、ディスペンス、組立てまでの待機時間、最終安定性、保守、信頼性に適合するものです。.
工程を簡素化するなら1Kジェル
すぐにディスペンスできる包装、ビードの配置制御、柔らかな接触を優先する場合は、メーターミックスの制御や可使時間を避けられます。.
形状安定性には後硬化ゲルを使用
界面を濡らした後の長時間曝露において、最終材料に垂直方向への移動や振動に対する高い耐性が求められる場合は、硬化制御型システムを選択してください。.
成形性とメンテナンスにはパテを使用
不規則な形状のハードウェア周辺で、技術者が界面を成形、交換、または手直しする必要がある場合は、軟質パテを検討してください。.
デリケートな表面の近くではシリコーンフリーゲルを使用
機能に影響を及ぼす移行が懸念される光学部品、接点、コーティング、リレー、接着領域の周辺では、非シリコーン系の化学組成を検討します。.
プロセスウィンドウに合わせてカスタマイズ
実際のラインに合わせて、導電性、粘度、スランプ、柔軟性、誘電特性、硬化性、パッケージ形態のバランスを取ります。.
接着層厚みとレオロジー
最終接合界面に応じて液状ギャップフィラーを選定
バルク熱伝導率は入力項目の一つにすぎません。最終的なデバイス温度は、ギャップ、ビード体積、濡れ性、圧縮後厚さ、接触面積、そして組立・エージング後に残る材料にも左右されます。.
単離した材料単体の数値ではなく、吐出後および組立後の界面を評価してください。.最小・公称・最大ギャップ
基板、部品、筐体、締結具、キャスティングの公差を含めた実際の積層状態を測定します。.
ビード体積と圧縮後厚さ
ショット量と塗布パターンは、見た目で吐出量を決めるのではなく、最終的な広がり面積、接着層、はみ出し余裕に結び付けて設定します。.
粘度、降伏応力、スランプ
材料は、生産速度でノズルから吐出でき、閉鎖前に所定の形状を保持し、利用可能な圧力で広がらなければなりません。.
熱インピーダンスと接触
実際の厚さと界面圧力で熱伝達を試験します。より高いW/mK値でも、厚い接着層や閉じ込められたボイドは補えません。.
Dielectric and Cleanliness Needs
Consider voltage, conductive edges, contamination-sensitive surfaces, outgassing, oil bleed and cleaning compatibility.
Aging and Mechanical Movement
Check thermal cycling, vibration, shock, pump-out, cracking, cure stability and movement between materials with different CTE.

Dispensing Engineering
Engineer the Thermal Gel Dispensing Process
A material that works in a hand syringe may behave differently through production hose length, pump shear, nozzle restriction, temperature, stop-start cycles and takt time. Qualify the material and equipment together.
Package and Feed
Match syringe, cartridge, pail or bulk supply with storage, filler stability, air removal and line-side handling.
Pump and Material Rheology
Confirm pressure, flow, shear, refill behavior and material recovery with pneumatic, screw or positive-displacement equipment.
Nozzle and Shot Control
Set tip geometry, stand-off, speed, start/stop behavior and shot volume around the real bead target.
Bead Pattern and Wetting
Design dots, lines, spirals or paths that spread across the useful contact area without trapping air or flooding keep-out zones.
Assembly Delay and Slump
Check bead shape after the maximum open delay, vertical orientation, vibration and any pre-cure movement before closure.
Inspection and Traceability
Define volume verification, vision limits, missing-shot detection, cure evidence, lot control and reaction plans.
Two-Part Control
Control Mixing, Pot Life and Cure for Post-Curing Gap Fillers
Two-part materials can combine excellent wetting during assembly with soft final stability. Their performance depends on accurate metering, mixing, air control and complete cure through the actual dispensed volume.
Maintain the Mix Ratio
Track pump balance, cartridge condition, pressure and start-up material so both components enter the static mixer consistently.
Confirm Homogeneity
Mixer geometry, flow rate and viscosity balance affect streaking, cure uniformity and final mechanical behavior.
Prevent Entrapped Voids
Manage cartridge loading, pail change, purge, hose connections, nozzle position and bead intersection to reduce air.
Respect Pot Life and Open Time
Define how long mixed material can remain in the system and how long the dispensed bead can wait before assembly.
Verify the Real Cure Profile
Temperature, material volume, heat-sink mass and enclosure geometry can make the actual cure different from a thin lab sample.
Lock the Production Window
Document storage, warm-up, purge, dispense, assembly, cure, inspection and acceptable rework before release.

Too little volume, poor pattern design or premature contact can leave air in the useful thermal footprint.
Excess Gel and Keep-Out Contamination
Too much material or insufficient escape space can flood connectors, optics, vents, contacts or bonding areas.

A bead can move during delay or vertical handling, changing coverage before the housing reaches final position.
Nozzle Blockage and Shot Drift
Filler, cure, temperature, idle time and pressure variation can change shot mass or stop the process.
Pump-Out, Separation and Aging
Thermal cycling and movement can alter contact, while filler settling or oil bleed can change material behavior.

マテリアルのカスタマイズを探索するよくあるご質問
Liquid Gap Filler FAQ
Final selection must be validated with the actual equipment, bead pattern, gap, cure and reliability conditions.
液状ギャップフィラーとは？
A liquid gap filler is a dispensable thermal interface material used to replace air between uneven heat-generating components and cooling surfaces. It conforms to complex topography and is commonly supplied as gel, putty or a cure-in-place system.
How is liquid gap filler different from a thermal pad?
Liquid filler is dispensed and can cover variable gaps or mixed component heights with low pressure. A pad is pre-formed, provides defined thickness and supports clean placement without a liquid dispensing process.
1K熱伝導ゲルと二液型熱伝導ゲルの違いは何ですか？
A 1K gel is pre-mixed and avoids on-line mix-ratio control. A two-part or post-curing gel is metered and mixed, then cures after dispensing. It requires pot-life and cure control but can provide stronger final shape stability.
Does every liquid gap filler need to cure?
No. Some one-component gels and putties remain soft or are supplied in a ready-to-use state. Other products cure after dispensing. The choice depends on stability, rework, storage and production needs.
熱伝導率は高ければ高いほど常に良いのでしょうか？
No. Final temperature also depends on bond-line thickness, wetting, contact area, voids and aging. A material that dispenses and conforms well can outperform a higher-W/mK material with a poor final interface.
What controls liquid gap filler dispensing quality?
Material temperature, viscosity, package, pump, hose, nozzle, pressure, speed, shot size, bead path, air control, idle time and assembly delay can all change the result.
How can voids be reduced?
Control material loading, purge, nozzle position, bead intersections, assembly direction, closure speed and spread path. Validate voids in the actual interface rather than only inspecting the bead surface.
When should silicone-free thermal gel be used?
Consider silicone-free chemistry near optics, cameras, sensitive contacts, relays, coatings or downstream bonding where silicone migration, fogging or oil bleed could affect function.
Can liquid gap filler be reworked?
Reworkability depends on chemistry and cure state. Many soft 1K gels or putties can be removed more easily than cured systems, but residue, cleaning method and replacement access must be tested.
