技术问答

光模块作为核心光学电子设备，高功率和小型化是其重要的两个发展方向；但这很容易带来一些负面影响，如散热问题。针对100G光模块中高发热量的TOSA/ROSA及光芯片部位，8W/m.k及以上导热系数的垫片材料是行业内普遍在采用的界面填充方案；但也存在诸如导热效率不够、厚度难以做薄、装配效率低下、小分子挥发等问题。在此背景下，PARKER CHOMERICS旗下的THERM-A-GAP Gel 75新型凝胶型液态导热材料，具备多种优异性能，可有效弥补常规垫片在光模块应用中存在的不足。

THERM-A-GAP Gel 75是Parker Chomerics新推出的一款高性能的凝胶型液态导热材料，其应用于100G光模块具备如下优势：

1、具备优异的导热性能。其导热系数高达7.5W/m.k，相比同等导热系数的垫片材料，其单位时间、单位面积及单位温差的前提下，可传递更多的热量。

2、形态呈膏状、易于压缩，对器件无应力损伤；最小使用厚度为0.2mm，表面润湿性好，可有效降低接触热阻及自身热阻，热量传递的路径更短、传热效率更高。

3、流动性好，挤出速率为30g/min@90Psi，适合自动化点胶；可有效提升生产效率、降低人工成本。

4、TML为0.18%，CVCM为0.05%；小分子硅氧烷挥发分已达到航天级应用材料限值标准。可最大化降低对光模块中光路传输的影响。

5、击穿电压高达8.7KV@1mm，体积电阻率高达10¹⁴Ω.cm，可有效降低长期使用过程中短路的风险。

6、耐温范围宽。其工作温度为-40℃~200℃，完全符合光模块应用环境对耐温的要求。

7、符合ROHS及V-0阻燃要求，各项常规及可靠性测试报告齐全，产品质量有保障，使用更安全。

综上所述，THERM-A-GAP Gel 75这款单组分导热凝胶应用于100G光模块，非常有利于缓解诸如TOSA/ROSA及光芯片等部位的导热散热问题。相比传统垫片类导热材料也具备诸多应用优势。
