Thermal interface materials (TIMs)—such as TIM1, TIM1.5, or TIM2—play a crucial role in overall system performance. Metal-based TIMs offer the lowest thermal resistance, meet industry reliability standards, and can be customized to suit specific package or system requirements. As the foremost provider of metal-based TIM solutions, Indium Corporation is ready to help you integrate these materials into your products and applications.
Solder TIMs (sTIM) are reflowed forming an intermetallic bond between the surfaces, offering the lowest contact resistance available. We have a high bulk thermal conductivity (86 W/mK), which means less sensitivity to bondline thickness and coplanarity issues compared to polymeric TIMs.
可压缩(非回流)TIMs
我们的专利产品 Heat-Spring® 是 TIM1.5、TIM2 以及预烧和测试应用的理想选择,它提供了一种无需回流焊的可压缩金属基 TIM 解决方案。其性能可与焊接 TIM 相媲美。
相变 TIM 最初以固态应用,但来自源的热量会将其转化为液态金属。我们提供几种在 60°C 至 80°C 温度范围内发生相变的无镓合金。
特点
86 W/mK
Indium’s high bulk thermal conductivity (86 W/mK) ensures less sensitivity to bond line thickness and coplanarity issues compared to polymer-based TIMs. Unlike graphite TIMs, which struggle with Z-axis heat transfer, metal-based TIMs deliver superior conductivity in all directions
.02cm2-C/W
金属 TIM 通过高表面润湿性最大限度地降低了热接触电阻,再加上其高体积传导性,从而降低了整体热阻。
长期可靠性
几十年来,金属基 TIM 凭借其性能和经受 TC、TS、HAST 和 HTOL 等标准可靠性测试的能力,一直备受信赖。
符合要求
铟是一种软金属,比纯铅软六倍,可在室温下退火,从而使其能够以最小的界面应力适应热膨胀。
热界面材料产品
金属基 TIM 可在大多数表面上流动和润湿,在所有平面上都具有较高的各向同性导热性,并且不会抽出或烤出。金属 TIM 具有较低的屈服强度和流动强度,使 TIM 既能适应表面粗糙度缺陷,也能适应因 CTE 不匹配而产生的翘曲。因此,整体热阻 (Rth) 较低。
Folks, Dr. Ron: For my next several posts, I would like to chat with Indium Corporation’s metal thermal interface materials (TIMs) Product Manager, Jon Major, about metal TIMs. Jon, can you tell us
In our modern world gallium is used everywhere, and modern life would be unrecognizable without the benefits it provides. As you are reading this, the nearest gallium (Ga) atoms are most likely found
