Our system immediately matches and selects pieces according to your BOM. You merely should assessment and confirm the selections.
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)。
Partnering with JLCPCB for robust PCB answers that meet the demanding environmental specifications of vital infrastructure tasks.
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;

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。
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 all the approach—from purchasing and components sourcing to PCBA prototyping—you could acquire your concluded boards in as rapidly as one particular 7 days. Permitting you to iterate, make improvements to, and PCB絕緣 produce 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。
