Mabhodhi edunhundiwo makuru ezvikamu zvezvigadzirwa zvemagetsi.Ngatitarisei kune zvikamu zvemabhodhi edunhu:
1. Pad:
Mapedhi maburi esimbi anoshandiswa solder component pini.
2 layer:
Zvichienderana nekugadzirwa kwebhodhi redunhu, pachava nemativi maviri, 4-layer, 6-layer, 8-layer, nezvimwewo. Nhamba yezvikamu zvinowanzoita kaviri.Kuwedzera kune chiratidzo chechiratidzo, kune mamwe maturu anoshandiswa kutsanangura kugadzirisa.
3. Via:
Zvinoreva vias ndezvekuti kana dunhu risingakwanisi kuita ese masaini maratidziro pane imwe nhanho, iyo mitsetse yechiratidzo inofanira kubatanidzwa mhiri kwezvikamu kuburikidza ne.Vias kazhinji yakakamurwa kuva mhando mbiri, imwe isimbi kuburikidza, imwe yacho isiri-simbi kuburikidza.Metal via inoshandiswa kubatanidza mapini echikamu pakati pezvikamu.Iyo fomu uye dhayamita yeiyo via zvinoenderana nehunhu hwechiratidzo uye zvinodikanwa zvechigadzirwa chekugadzira.
4. Zvikamu:
Zvikamu zvinotengeswa paPCB.Iko kusanganiswa kwegadziriro pakati pezvikamu zvakasiyana-siyana kunogona kuita mabasa akasiyana, rinovawo basa rePCB.
5. Mamiriro:
Iyo marongerwo inoreva mutsara wechiratidzo unobatanidza mapini emudziyo.Hurefu nehupamhi hwemagadzirirwo zvinoenderana nemhando yechiratidzo, senge saizi yazvino, kumhanya, nezvimwe.
6. Kudhinda Sikirini:
Chidzitiro Kudhinda kunogona zvakare kunzi chidzitiro Kudhinda layer, iyo inoshandiswa kumaka akasiyana ane hukama ruzivo pane izvo zvikamu.Iyo skrini Kudhinda kunowanzo kuchena, uye iwe unogona zvakare kusarudza iyo ruvara zvinoenderana nezvako zvaunoda.
7. Solder mask:
Basa guru remask solder nderokudzivirira pamusoro pePCB, kuumba chidziviriro chekudzivirira nehumwe hukuru, uye kudzivirira kusangana pakati pemhangura nemhepo.Iyo solder mask inowanzo girini, asi kune zvakare tsvuku, yero, yebhuruu, chena, uye nhema.
8. Gomba rekuisa:
Gomba rekumisikidza igomba riri nyore kuiswa kuti rigadzirwe kana kugadzirisa.
9. Kuzadza:
Kuzadza imhangura inoshandiswa kune network network, iyo inogona kunyatso kuderedza impedance.
10. Miganhu yemagetsi:
Muganhu wemagetsi unoshandiswa kuona zviyero zvebhodhi redunhu, uye zvikamu zvose pabhodhi redunhu hazvifaniri kudarika muganhu uyu.
Izvo zvikamu gumi zviri pamusoro apa ndiyo hwaro hwekuumbwa kwebhodhi redunhu, uye kuzadzikiswa kwemamwe mabasa kuchiri kuda kurongwa muchip kuti zvibudirire.
Kana uine chero mibvunzo, unogamuchirwa kushanyaPCBFuture.com.
