What Does PCB絕緣 Mean?

瞬態過電壓是指在極短時間內發生的高電壓脈衝,可能持續幾微秒到幾毫秒。這些過電壓不屬於設備正常運作的工作電壓範圍,但必須被考慮進安全設計,因為它們足以擊穿絕緣或設備損壞。

依據UL1310下列條文要求,輸出接頭(output connector)不可使用同軸電纜的連接器(coaxial cable connector)。

Place orders in minutes and keep track of order position in authentic-time. Visible development tracking displays every step, from evaluate to creation to transport.

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。

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。

.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。
