原帖由 狐狸糊涂 于 2011-9-27 00:47 发表 冰鱼你买的你应该了解的!你介绍介绍 这个好奇怪的名字 嘻嘻,我还真是不了解 只是手上只有Mcap的Supreme,现在耳放摩得整体声音比较明亮,想要调得更柔和自然些,所以订了一些原件,同时也想换别的焊锡试下。因为一共就没几个焊点,顺手挑了个最小包装的焊锡,就是这个。介绍很简单“Johnson's IA-423 is a "ternary eutectic" alloy, i.e., a composition comprising its three component elements (tin, silver and copper) that both melts and flows at a single low temperature, 423°F (217°C). Practically speaking, eutectic alloys are shinier, stronger and have a tighter, more refined grain structure than near-eutectic or non-eutectic compositions. As a result, IA-423 is becoming a highly desireable replacement for the lead-containing solders used in electronic assemblies, printed circuit boards and many other high-tech soldering applications. Audiophiles also claim that IA-423 is the best sounding solder they've ever heard, possibly due to its improved conductivity, owing to both its high silver and copper content.”,所以上来问问有没人用过 |
