Through the analysis of the parasitic characteristics of vias, we can see that in high-speed PCB design, seemingly simple vias often bring great negative effects to circuit design. In order to reduce the adverse effects caused by the parasitic effects of the vias, the following can be done in the design:

1. Considering the cost and signal quality, choose a reasonable size via size. For example, for the 6-10 layer memory module PCB design, it is better to use 10/20Mil (drilled/pad) vias. For some high-density small-size boards, you can also try to use 8/18Mil. hole. Under current technical conditions, it is difficult to use smaller vias. For power or ground vias, you can consider using a larger size to reduce impedance.

2. The two formulas discussed above can be concluded that using a thinner PCB is beneficial to reduce the two parasitic parameters of the via.

3. Isku day inaadan bedelin lakabyada raadadka calaamadaha ee sabuuradda PCB-ga, taas oo macnaheedu yahay, isku day inaadan isticmaalin vias aan loo baahnayn.

4. biinanka korontada iyo dhulka waa in la qodaa meel u dhow, hogaanka u dhexeeya fiilada iyo biinanka waa in uu ahaadaa mid gaaban intii suurtagal ah, sababtoo ah waxay kordhin doonaan inductance. Isla mar ahaantaana, awoodda iyo hogaanka dhulka waa inay ahaadaan kuwo dhumuc weyn leh si loo yareeyo caqabada.

5. Dhig qaar ka mid ah fiisooyinka dhulka hoostiisa mara ee u dhow fiisaha lakabka calaamada si aad u hesho wareegga ugu dhow ee calaamada. Xitaa waa suurtogal in la dhigo tiro badan oo dhulka loo maro vias-ka looxa PCB-ga. Dabcan, naqshaddu waxay u baahan tahay inay noqoto mid dabacsan. Qaabka loo maro mar hore laga hadlay waa kiiska meesha ay ku yaalliin suufyo lakab kasta. Mararka qaarkood, waxaan yarayn karnaa ama xitaa ka saari karnaa suufka lakabyada qaarkood. Gaar ahaan marka cufnaanta fiisuhu aad u sarreeyo, waxay u horseedi kartaa samaynta jeexdin jajab ah oo kala sooca wareegga lakabka naxaasta ah. Si loo xalliyo dhibaatadan, marka lagu daro dhaqdhaqaaqa booska via, waxaan sidoo kale ka fiirsan karnaa gelinta via lakabka copper. Cabbirka suufka waa la dhimay.
