Hi-Flow 225UT應(yīng)用材料特性：

壓敏相變化導(dǎo)熱界面材料，具有天然粘性的55℃相變化復(fù)合物，高可視度的保護(hù)膜拉片

Hi-Flow 225UT材料說(shuō)明：

Hi-Flow 225UT是一款設(shè)計(jì)應(yīng)用于高性能處理器的發(fā)熱元器件和散熱器之間導(dǎo)熱的壓敏界面材料，它是一種具有天然粘性的55℃相變化復(fù)合物，該材料背面有PET離型膜，正面附有高可視度的保護(hù)膜拉片。一旦達(dá)到55℃的相變化溫度，Hi-Flow 225UT立刻潤(rùn)濕導(dǎo)熱界面，流動(dòng)的特性帶來(lái)最低的熱陰，裝配時(shí)需要一定的壓力讓材料流動(dòng)，流動(dòng)時(shí)涂層不會(huì)滴漏。

Hi-Flow 225UT典型應(yīng)用：

彈片/扣具安裝

獨(dú)立的功率半導(dǎo)體和模塊

Hi-Flow 225UT技術(shù)優(yōu)勢(shì)分析：

可按客戶尺寸模切，僅限于正方形和長(zhǎng)方形.提供經(jīng)過(guò)模切的卷材制品，啤半穿、除廢料，附有拉片（不能有孔）

Hi-Flow? 225UT is designed as a pressure sensitive thermal interface material for use between a high performance processor and a heat sink. Hi-Flow? 225UT is a thermally conductive 55°C phase change composite with inherent tack. The material is supplied on a polyester carrier liner and is available with high-visibility protective tabs. Above its phase change temperature,

Hi-Flow? 225UT wets-out the thermal interface surfaces and flows to produce the lowest thermal impedance. The material requires pressure of the assembly to cause flow. Hi-Flow? 225UT coatings will resist dripping.

Application Methods

 1. Hand-apply Hi-Flow? 225UT to a room- temperature heat sink. The Hi-Flow? 225UT pad exhibits inherent tack and can be hand-applied similar to an adhesive pad. The tab liner can remain on the heat sink and pad throughout shipping and handling until is it is ready for final assembly.
