Best Technology ndeimwe yakanakisisa pcb vagadziri uye akadhindwa redunhu bhodhi vatengesi mu China
"Single Sided PCB", kana kuti unogona kuitumidza seSingle Layer PCB, kana 1L PCB. Ikoko's hapana imwe chete yemhangura inoteedzera pabhodhi, SMD zvikamu kune rimwe divi (kuburikidza negomba zvikamu kune rimwe divi), asi zvakare hapana PTH (yakaputirwa neburi) kana Via, ine chete NPTH (hapana-yakaputirwa buri gomba), kana nzvimbo. gomba.
Ndiyo mhando yakachipa yebhodhi, uye inoshandiswa mubhodhi rakareruka. Kuti uwane mutengo wakachipa, dzimwe nguva vanhu vanoshandisa CEM-1, CEM-3 pachinzvimbo cheFR4, kugadzira bhodhi redunhu. Dzimwe nguva, fekitori inobvisa imwe copper trace kubva ku2L CCL (copper clad laminate) kana pasina 1L FR4 raw materail iripo.
Ikoko's imwe yakajairika bhodhi"2L PCB" iyo ine 2 copper trace, uye yakatumidzwawo se"Kaviri Sided PCB" (D/S PCB), uye PTH (Via) inofanirwa, asi ichiri kuita't ine Gomba Rakavigwa kana Bofu. Zvikamu zvinogona kuunganidzwa pamativi ese epamusoro uye epasi, saka iwe unoita't inoda kunetseka nezve kwainoisa zvikamu pabhodhi, uye haifanirwe kushandisa kuburikidza negomba zvikamu izvo zvinogara zvichidhura kupfuura SMD imwe.
Parizvino iyi ndeimwe yemhando inonyanya kufarirwa yePCB paPasi, uye tinokwanisa kupa maawa makumi maviri nemana nekukurumidza-shanduko sevhisi kwavari. Dzvanya pano kuti uone Nguva Yekutungamira yemhando mbiri dzemabhodhi edunhu.
Chimiro cheRutivi Rumwechete (1L) PCB
Heino iyo yekutanga layer kumusoro kune rimwe divi (S/S) FR4 PCB (kubva kumusoro kusvika pasi):
Yepamusoro silkscreen/Legend: kuziva zita rePAD yega yega, bhodhi chikamu nhamba, data, nezvimwe;
Yepamusoro Surface kupedzisa: kuchengetedza yakafumurwa mhangura kubva kune oxidation;
Pamusoro Soldermask (kufukidza): kuchengetedza mhangura kubva kune oxidation, kuti isatengeswa panguva yeSMT process;
Yepamusoro Trace: mhangura yakamisikidzwa zvinoenderana nedhizaini kuti iite basa rakasiyana
Substrate/Core zvinhu: Zvisiri-conductive zvakaita seFR4, FR3, CEM-1, CEM-3.
