英特尔和AMD所有采用了钎焊的CPU是?是不是硅脂用了几年就会干,而钎焊不用担心这个问题?

回答1:

英特尔i5 2550k以前的部分i5,i7 2700k以前部分四核i7,所有旗舰级i7 920 990x 3960x 4960x 5960x 6950x 7950x是钎焊

至于AMD,古董三四核六核和部分双核是钎焊,现在的fx也是。

是的,钎焊的CPU不会堆积热量,所以一般不会发生干了情况。

钎焊所用的散热填充材料是低熔点金属,或者称作“液态金属”。金属的导热能力比硅脂好很多。而且硅脂使用时间太久,忽冷忽热的温差变化,会逐渐变干变硬。所以使用钎焊的CPU,要比用硅脂的,在散热方面有优势。但钎焊的成本也比硅脂高。

钎焊

是指低于焊件熔点的钎料和焊件同时加热到钎料熔化温度后,利用液态钎料填充固态工件的缝隙使金属连接的焊接方法称。钎焊时,首先要去除母材接触面上的氧化膜和油污,以利于毛细管在钎料熔化后发挥作用,增加钎料的润湿性和毛细流动性。根据钎料熔点的不同,钎焊又分为硬钎焊和软钎焊。

硅脂

硅脂是由精炼合成油作为基础油稠无机稠化剂,并加有结构稳定剂、防腐蚀添加剂精制而成,具有良好的防水密封性、防水、抗溶剂性和抗爬电性能,不腐蚀金属,与橡胶多具有较好的适应性,用于卫浴器材、密封圈、电子电气行业的防水密封及润滑。

看具体情况的,

硅脂这玩意作为cpu die和顶盖之间导热填充物很早就开始用了,貌似农企最先搞,不过只在低端
cpu用,这规则一直延续到现在——FM平台的APU硅脂,AM平台的FX钎焊。intel以前很良心,赛
扬D都是钎焊,应该是LGA775开始学amd也用硅脂了,酷睿2据老司机说是低端双核用硅脂,高端
四核用钎焊。intel 22nm以后竟然在2000多块钱的i7k也开始用硅脂了,而且还是极其廉价的,导

硅脂干了只要不超继续用,cpu里面不加电压温度也就那个熊样。

i7 870 i5 750都是硅脂对应的x3470 x3430都是硅脂。但是i5 650是一半硅脂 一半钎焊
i5 2300级别钎焊 i3 2100 崩腾之流硅脂
