塑料等柔性基板非常適合滿足柔性電路板的絕緣要求。 另一方面,金屬是優良的熱導體,同時保持功率電子的冷卻。

衰减原因:高温高湿下,水汽渗透到表面处理层,溶解残留离子(如助焊剂、金属离子)形成 “电解液”,离子在偏压作用下迁移,让绝缘电阻降低 —— 就像橡胶吸水后变潮湿,导电能力变强;

不行。兩者是獨立的安全設計參數,爬電距離用於防止表面漏電,間隙距離則防止空氣放電。缺一不可,需分別依標準查表計算。

若設計人員未能清楚區分這兩項距離,可能導致誤判風險來源,進而影響產品安全性與安規通過率。

By contrast, whenever you click a Microsoft-provided advertisement that seems on DuckDuckGo, Microsoft Promoting isn't going to associate your advertisement-simply click behavior that has a user profile. Furthermore, it does not retailer or share that information and facts other than for accounting uses.

設備運行環境中的污染狀況會顯著影響絕緣性能。污染等級越高,越容易在絕緣表面形成導電通路,增加漏電或電弧風險,因此需設定更長的爬電距離。

By streamlining your complete method—from PCB絕緣 buying and components sourcing to PCBA prototyping—you may get your finished boards in as rapidly as a single 7 days. Enabling you to iterate, increase, and provide by the due date as well as.

工作電壓會直接影響你需要設計的「間隙距離」和「爬電距離」大小。電壓越高,潛在的絕緣需求和空氣/表面擊穿風險越高,安全距離需求就越大。

.介質不同:間隙距離依賴空氣的絕緣能力,而爬電距離取決於固體絕緣材料表面的性能。
