A Simple Key For PCB絕緣 Unveiled

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）。

不會。海拔高度只會影響空氣的介電強度，因此只會調整「間隙距離」；爬電距離設計不受高度影響。

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；

JLCPCB fulfills the stringent quality specifications of Siemens' industrial automation solutions by disciplined manufacturing and process control.

梳狀圖案，梳狀電路是一種“多指”交錯密集電路圖案，可用於電路板清潔度和綠色油漆絕緣的高壓測試。

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 the entire procedure—from buying and components sourcing to PCBA prototyping—you may obtain your concluded boards in as quick as 1 7 days. Permitting you to definitely iterate, boost, and supply on time or maybe.

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。

不同的絕緣措施(如基本絕緣、雙重絕緣或強化絕緣)對爬電距離的要求有所不同，越高等級的絕緣保護，所需距離越長。
