6 Wosanjikiza Pcb mphamvu kotunga bata ndi mphamvu kotunga phokoso mavuto

Pamene teknoloji ikupitirirabe patsogolo ndipo zipangizo zimakhala zovuta kwambiri, kuonetsetsa kuti magetsi okhazikika amakhala ofunika kwambiri.Izi ndizowona makamaka kwa ma PCB a 6-wosanjikiza, komwe kukhazikika kwa mphamvu ndi nkhani zaphokoso zimatha kukhudza kwambiri kutumizira ma siginecha komanso kugwiritsa ntchito mphamvu zamagetsi. Mu positi iyi yabulogu, tiwona njira zingapo zothetsera mavutowa.

1. Kumvetsetsa kukhazikika kwamagetsi:

Kukhazikika kwamagetsi kumatanthawuza kuthekera kopereka ma voliyumu osasinthika komanso apano kuzinthu zamagetsi pa PCB. Kusinthasintha kulikonse kapena kusintha kwa mphamvu kungapangitse kuti zigawozi zisagwire ntchito kapena kuonongeka. Chifukwa chake, ndikofunikira kuzindikira ndikuwongolera zovuta zilizonse zokhazikika.

2. Dziwani zovuta zaphokoso lamagetsi:

Phokoso lamagetsi ndikusintha kosafunikira kwamagetsi kapena milingo yamakono pa PCB. Phokosoli limatha kusokoneza magwiridwe antchito azinthu zodziwika bwino, kupangitsa zolakwika, kusagwira bwino ntchito, kapena kunyonyotsoka. Kuti mupewe zovuta zotere, ndikofunikira kuzindikira ndikuchepetsa zovuta zaphokoso lamagetsi.

3. Ukadaulo wotsikira pansi:

Chimodzi mwa zifukwa zazikulu za kukhazikika kwa magetsi ndi vuto la phokoso ndikuyika pansi kosayenera. Kugwiritsa ntchito njira zoyenera zokhazikitsira pansi kungathandize kwambiri kukhazikika komanso kuchepetsa phokoso. Ganizirani kugwiritsa ntchito ndege yolimba pa PCB kuti muchepetse malupu apansi ndikuwonetsetsa kuti pali kuthekera kofanana. Kuphatikiza apo, kugwiritsa ntchito ndege zapansi pagawo la analogi ndi digito kumalepheretsa kulumikizana kwaphokoso.

4. Decoupling capacitor:

Ma decoupling capacitor omwe amayikidwa bwino pa PCB kuyamwa ndikusefa maphokoso apamwamba kwambiri, ndikuwongolera bata. Ma capacitor awa amagwira ntchito ngati malo osungira mphamvu amderalo, omwe amapereka mphamvu nthawi yomweyo kuzinthu zomwe zimachitika pakanthawi kochepa. Poyika ma capacitor odulira pafupi ndi ma pin amagetsi a IC, kukhazikika kwadongosolo ndi magwiridwe antchito zitha kusintha kwambiri.

5. Network yogawa yotsika ya impedance:

Kupanga ma netiweki ogawa mphamvu otsika (PDNs) ndikofunikira kuti muchepetse phokoso lamagetsi ndikusunga bata. Lingalirani kugwiritsa ntchito njira zokulirapo kapena ndege zamkuwa kuti muchepetse kutsekeka. Kuphatikiza apo, kuyika ma bypass capacitor pafupi ndi mapini amagetsi ndikuwonetsetsa kuti mphamvu zazifupi zitha kupititsa patsogolo mphamvu za PDN.

6. Ukadaulo wosefera ndi chitetezo:

Kuti muteteze ma sign amphamvu ku phokoso lamagetsi, ndikofunikira kugwiritsa ntchito njira zoyenera zosefera ndi zotchingira. Gwiritsani ntchito fyuluta yotsika kwambiri kuti muchepetse phokoso lambiri ndikulola kuti chizindikiro chomwe mukufuna chidutse. Kukhazikitsa njira zodzitchinjiriza monga ndege zapansi, zotchingira zamkuwa, kapena zingwe zotetezedwa zingathandize kuchepetsa kulumikizana kwaphokoso ndi kusokoneza kuchokera kunja.

7. Wosanjikiza mphamvu pawokha:

Pamagetsi okwera kwambiri, tikulimbikitsidwa kugwiritsa ntchito ndege zamagetsi zosiyana pamagawo osiyanasiyana. Kudzipatula kumeneku kumachepetsa chiwopsezo cha kulumikizana kwa phokoso pakati pa madera osiyanasiyana amagetsi, kuwonetsetsa kuti magetsi azikhala okhazikika. Kuphatikiza apo, kugwiritsa ntchito ukadaulo woyenera kudzipatula, monga zosinthira kudzipatula kapena ma optocouplers, zitha kupititsa patsogolo chitetezo ndikuchepetsa zovuta zokhudzana ndi phokoso.

8. Kuyesezeratu ndi kusanthula masanjidwe:

Kugwiritsa ntchito zida zoyeserera komanso kusanthula koyambira kungathandize kuzindikira kukhazikika komwe kungathe kuchitika komanso phokoso musanamalize mapangidwe a PCB. Zida izi zimawunika kukhulupirika kwamphamvu, kukhulupirika kwa ma signature, komanso nkhani zofananira ndi electromagnetic (EMC). Pogwiritsa ntchito njira zopangira zoyeserera, munthu amatha kuthana ndi zovuta izi ndikuwongolera masanjidwe a PCB kuti apititse patsogolo magwiridwe antchito.

Pomaliza:

Kuwonetsetsa kuti magetsi azikhala okhazikika komanso kuchepetsa phokoso lamagetsi ndizofunikira kwambiri pakupanga bwino kwa PCB, makamaka pakutumiza ma siginecha komanso kugwiritsa ntchito ma voliyumu apamwamba. Pogwiritsa ntchito njira zoyenera zoyambira pansi, kugwiritsa ntchito ma capacitor ochepetsera, kupanga maukonde ogawa ocheperako, kugwiritsa ntchito zosefera ndi zotchingira, ndikuchita zofananira ndi kusanthula kokwanira, nkhanizi zitha kuthetsedwa bwino komanso mphamvu yokhazikika komanso yodalirika yopezeka. Kumbukirani kuti machitidwe ndi moyo wautali wa PCB yopangidwa bwino zimadalira kwambiri chidwi cha kukhazikika kwa magetsi ndi kuchepetsa phokoso.
