Kupyolera mu kusanthula makhalidwe parasitic wa vias, tikhoza kuona kuti mkulu-liwiro PCB kamangidwe, vias zooneka zosavuta nthawi zambiri kumabweretsa zotsatira zoipa kwa dera kamangidwe. Pofuna kuchepetsa mavuto chifukwa cha parasitic zotsatira za vias, zotsatirazi zikhoza kuchitika mu kapangidwe:

1. Poganizira mtengo ndi mtundu wa chizindikiro, sankhani kukula koyenera kudzera mu kukula. Mwachitsanzo, kwa 6-10 wosanjikiza kukumbukira gawo PCB kapangidwe, ndi bwino kugwiritsa ntchito 10/20Mil (bowolera / PAD) vias. Pama board ena ang’onoang’ono ang’onoang’ono, mutha kuyesanso kugwiritsa ntchito 8/18Mil. dzenje. Pansi pamikhalidwe yamakono, ndizovuta kugwiritsa ntchito ma vias ang’onoang’ono. Pakuti mphamvu kapena pansi vias, mungaganizire ntchito yaikulu kukula kuchepetsa impedance.

2. Njira ziwiri zomwe takambiranazi zitha kuganiziridwa kuti kugwiritsa ntchito PCB yocheperako kumapindulitsa kuchepetsa magawo awiri a parasitic wa via.

3. Yesetsani kusintha zigawo za zizindikiro chizindikiro pa bolodi PCB, ndiko kuti, yesetsani ntchito vias zosafunika.

4. Mphamvu ndi zikhomo zapansi ziyenera kuponyedwa pafupi, ndipo kutsogolera pakati pa via ndi pini kuyenera kukhala kwaufupi momwe zingathere, chifukwa zidzawonjezera inductance. Panthawi imodzimodziyo, mphamvu ndi zotsogolera pansi ziyenera kukhala zazikulu momwe zingathere kuti muchepetse impedance.

5. Ikani ena vias pansi pafupi vias wa chizindikiro wosanjikiza kupereka yapafupi kuzungulira kwa chizindikiro. Ndikothekanso kuyika ma vias ambiri osafunikira pa bolodi la PCB. Zoonadi, kapangidwe kake kamayenera kukhala kosinthika. Kudzera mwachitsanzo chomwe takambirana kale ndi pomwe pali mapepala pagawo lililonse. Nthawi zina, tikhoza kuchepetsa kapena kuchotsa mapepala a zigawo zina. Makamaka pamene kachulukidwe vias kwambiri, zingachititse kuti mapangidwe yopuma poyambira kuti amalekanitsa kuzungulira mu mkuwa wosanjikiza. Kuthetsa vutoli, kuwonjezera kusuntha malo a via, tingathenso kuganizira kuika kudzera pa wosanjikiza mkuwa. Kukula kwa pedi kumachepetsedwa.
