高速PCB通孔設計需要注意哪些問題？

PCB通孔主要由孔、孔周圍的焊盤區、POWER 層隔離區三部分組成。在高速PCB設計中，往往需要採用多層PCB，而通孔是多層PCB設計的一個重要因素。高速PCB多層板中，訊號從某層互連線傳輸到另一層互連線就需要通過通孔來實現連接。那麼，高速PCB通孔設計需要注意哪些問題？

1、選擇合理的通孔尺寸。對於多層一般密度的PCB 設計來說，其鑽孔、焊盤、POWER 隔離區選用的較為理想的通孔尺寸為0.25mm、0.51mm、0.91mm;對於一些高密度的PCB ，也可以使用0.20mm、0.46mm、0.86mm 的通孔，也可以嘗試非穿導孔;對於電源或地線的通孔，則可以考慮使用較大尺寸，以減小阻抗。

2、POWER隔離區越大越好。

3、PCB 上的信號走線盡量不換層，即盡量減少通孔。

4、使用較薄的PCB有利於減小通孔的兩種寄生參數。

5、電源和地的管腳要靠近通孔，通孔和管腳之間的引線越短越好；同時電源和地的引線要盡可能粗，以減少阻抗;

6、在信號換層的通孔附近放置一些接地通孔，以便為訊號提供短距離迴路。

7、通孔長度也是影響通孔電感的主要因素。高速PCB設計時，為減小通孔帶來的問題，通孔長度一般控制在2.0mm以內。對於長度大於2.0 mm的通孔，通過增加通孔孔徑，可在一定程度上提高通孔阻抗連續性。當通孔長度為1.0 mm及以下時，最佳通孔孔徑為0.20 mm ~ 0.30 mm。

以上便是高速PCB通孔設計需要注意的問題，你都掌握了嗎？
