1. Mapedhi.
Pedhi igomba resimbi rinoshandiswa kutengeswa mapini ezvikamu.
2. Layer.
Circuit board zvinoenderana nekugadzirwa kweakasiyana, pachave nekaviri-mativi, 4-layer board, 6-layer board, 8-layer board, nezvimwewo, huwandu hwematanho anowanzo kupetwa, kuwedzera kune kuenda chiratidzo layer, kune zvimwe kune tsananguro yekugadziriswa neiyo layer.
3. Pamusoro pegomba.
Chirevo chekupwanya ndechekuti kana dunhu risingakwanisi kuwanikwa pamwero wese kurongeka kwechiratidzo, zvinodikanwa kubatanidza mitsetse yechiratidzo mukati mematanho nenzira yekuputika, perforation inowanzokamurwa kuita mhando mbiri, imwe yesimbi. perforation, imwe yeasiri-metallic perforation, apo simbi perforation inoshandiswa kubatanidza zvikamu zvepini pakati pezvikamu.Chimiro che perforation uye gomba dhayamita zvinoenderana nehunhu hwechiratidzo uye zvinodiwa zvekugadzira chirimwa.
4. Zvikamu.
Yakatengeswa pazvikamu zvePCB, zvikamu zvakasiyana pakati pekubatanidzwa kwekugadzirisa zvinogona kuita mabasa akasiyana-siyana, iyo iyo basa rePCB.
5. Kururamisa.
Alignment inoreva mitsetse yechiratidzo pakati pepini yemidziyo yakabatana, kureba uye hupamhi hwekurongeka kunoenderana nechimiro chechiratidzo, senge saizi yazvino, kumhanya, nezvimwewo, kureba uye hupamhi hwekurongeka kunosiyanawo.
6. Silkscreen.
Kudhinda skrini kunogona zvakare kunzi screen printing layer, inoshandiswa kune dzakasiyana siyana midziyo ine chekuita neruzivo rwemazita, kudhinda skrini kunowanzo kuchena, unogona zvakare kusarudza ruvara zvinoenderana nezvavanoda.
7. Solder resist layer.
Basa guru re soldermask layer nderokudzivirira pamusoro pePCB, kuumba chidziviriro chekudzivirira nehumwe hupamhi, nekuvhara kusangana pakati pemhangura nemhepo.Solder resist layer inowanzo girinhi, asi kune zvakare tsvuku, yero, yebhuruu, chena, dema solder resist layer sarudzo.
8. Makomba enzvimbo.
Positioning maburi akaiswa kuitira nyore kuisa kana debugging maburi.
9. Kuzadza.
Kuzadza kunoshandiswa kune network yepasi yemhangura yekuisa, inogona kunyatso kudzikisa iyo impedance.
10. Muganhu wemagetsi.
Muganhu wemagetsi unoshandiswa kuona ukuru hwebhodhi, zvese zvikamu pabhodhi hazvigone kudarika muganhu.
Izvo zvikamu gumi zviri pamusoro apa ndiyo nheyo yekuumbwa kwebhodhi, mamwe maitiro kana kudiwa kwekupisa mu chip kuti uwane purogiramu.
