The signal anti-pad size results in these tables demonstrates that the larger the anti-pad, the less insertion and return loss results. Because space is always ...
Via Effect

... anti-via、去掉NFP。 via barrel結構上,訊號經過的部份貢獻串聯電感效應,而訊號沒經過的部分(stub)貢獻電容效應,這兩者是相互trade-off的。板厚<100mils時,via ...
如何設計抗Crosstalk能力強的PCB鍍穿孔
https://sipitogether.blog
AntiPad指的是訊號的Via為了閃過Power/GND plane避免短路所隔離出的區域,往往會利用隔離的尺寸控制Via的阻抗。不過其實這個尺寸也會影響Crosstalk,因為如果隔離區越大, ...
