Pakadali pano, kukopera kwa PCB kumatchedwanso PCB cloning, PCB reverse design, kapena PCB reverse R&D pamakampani.Pali malingaliro ambiri okhudza tanthauzo la PCB kukopera mu makampani ndi maphunziro, koma si amphumphu.Ngati tikufuna kupereka tanthauzo lolondola la kukopera kwa PCB, tingaphunzire kuchokera ku labotale yovomerezeka ya PCB ku China: PCB kukopera Board, ndiye kuti, pamaziko a zinthu zomwe zilipo pakompyuta ndi matabwa ozungulira, kusanthula kwa matabwa adera kumachitika. Pogwiritsa ntchito ukadaulo wa R & D, ndi zikalata za PCB, zikalata za BOM, zikalata zachifanizo ndi zikalata zopanga silika za PCB zazinthu zoyambirira zimabwezeretsedwanso mu chiŵerengero cha 1: 1, kenako matabwa a PCB ndi zigawo zake zimapangidwa pogwiritsa ntchito zikalata zaukadaulo. ndi zikalata kupanga Mbali kuwotcherera, zowuluka pini mayeso, dera bolodi debugging, buku lathunthu choyambirira dera template gulu.Chifukwa zinthu zamagetsi zonse zimapangidwa ndi mitundu yonse ya matabwa ozungulira, seti yonse yaukadaulo yazinthu zilizonse zamagetsi imatha kutulutsidwa ndipo zinthuzo zitha kukopera ndikupangidwa pogwiritsa ntchito njira ya PCB kukopera.
Njira yogwiritsira ntchito luso la PCB board kuwerenga ndi yosavuta, ndiye kuti, choyamba jambulani bolodi loyang'anira kuti likopedwe, lembani mwatsatanetsatane chigawocho, kenako ndikuchotsani zigawozo kuti mupange BOM ndikukonzekera kugula zinthu, kenako jambulani bolodi yopanda kanthu kuti mujambule zithunzi. , ndiyeno kuwakonza ndi bolodi kuwerenga mapulogalamu kuwabwezeretsa PCB bolodi kujambula owona, ndiyeno kutumiza owona PCB kwa mbale kupanga fakitale kupanga matabwa.Pambuyo matabwa anapangidwa, iwo adzagulidwa Zigawo ndi welded kwa PCB, ndiyeno kuyesedwa ndi debugged.
Njira zenizeni zaukadaulo ndi izi:
Khwerero 1: pezani PCB, choyamba lembani zitsanzo, magawo, ndi malo a zigawo zonse pa pepala, makamaka mayendedwe a diode, chubu cha magawo atatu, ndi notch ya IC.Ndi bwino kutenga zithunzi ziwiri za malo gasi chinthu ndi digito kamera.Tsopano gulu la dera la PCB likuchulukirachulukira, ndipo ma triode a diode pa izo sizikuwoneka.
Khwerero 2: Chotsani zinthu zonse ndi malata pa dzenje la pad.Tsukani PCB ndi mowa ndikuyika mu sikani.Scanner ikasanthula, imayenera kukweza pang'ono ma pixel angapo kuti iwoneke bwino.Ndiye kupukuta pamwamba wosanjikiza ndi pansi wosanjikiza pang'ono ndi madzi yopyapyala pepala mpaka mkuwa filimu yowala, anawaika mu sikana, kuyamba Photoshop, ndi kusesa zigawo ziwiri mu mtundu.Dziwani kuti PCB iyenera kuyikidwa molunjika komanso molunjika mu sikani, apo ayi chithunzi chojambulidwa sichingagwiritsidwe ntchito.
Khwerero 3: Sinthani kusiyanitsa ndi kuwala kwa chinsalu kuti kusiyana pakati pa gawo ndi filimu yamkuwa ndi gawo lopanda filimu yamkuwa likhale lolimba.Kenako tembenuzirani chithunzi chachiwiri kukhala chakuda ndi choyera kuti muwone ngati mizereyo ili yomveka bwino.Ngati sichoncho, bwerezani izi.Ngati ndi zomveka, sungani zojambulazo monga mafayilo apamwamba a BMP ndi BOT BMP mumtundu wa BMP wakuda ndi woyera.Ngati pali vuto lililonse ndi kujambula, mutha kugwiritsa ntchito Photoshop kukonza ndikuwongolera.
Gawo lachinayi: sinthani mafayilo awiri amtundu wa BMP kukhala mafayilo amtundu wa PROTEL, ndikuwasamutsa kukhala magawo awiri mu PROTEL.Ngati malo a PAD ndi VIA pamiyezo iwiri amagwirizana, zikuwonetsa kuti masitepe oyambira ndi abwino kwambiri, ndipo ngati pali zolakwika, bwerezani masitepe achitatu.Choncho PCB bolodi kukopera ndi ntchito oleza mtima kwambiri, chifukwa vuto pang'ono zingakhudze khalidwe ndi ofanana digiri pambuyo bolodi kukopera.Gawo 5: atembenuke ndi BMP pamwamba wosanjikiza pamwamba PCB.Samalani kuti musinthe kukhala wosanjikiza wa silika, womwe ndi wosanjikiza wachikasu.
Ndiye mukhoza kufufuza mzere pamwamba, ndikuyika chipangizocho molingana ndi chojambula mu sitepe 2. Chotsani silika wosanjikiza mutatha kujambula.Bwerezani mpaka zigawo zonse zitakokedwa.
Gawo 6: kusamutsa pamwamba PCB ndi BOT PCB mu Protel ndi kuphatikiza iwo mu chithunzi chimodzi.
Gawo 7: ntchito chosindikizira laser kusindikiza pamwamba wosanjikiza ndi pansi wosanjikiza mandala filimu (1: 1 chiŵerengero), koma filimu pa PCB, ndi yerekezerani ngati pali cholakwika.Ngati mukulondola, mupambana.
Bolodi lokopa ngati bolodi loyambirira linabadwa, koma linali litamalizidwa theka chabe.Tiyeneranso kuyesa ngati luso lamagetsi la board liri lofanana ndi la bolodi loyambirira.Ngati ziri chomwecho, izo zachitikadi.
Zindikirani: ngati ndi bolodi la multilayer, liyenera kupukutidwa mosamala mpaka mkati, ndikubwereza ndondomeko zokopera kuchokera pa sitepe 3 kupita ku sitepe 5. Zoonadi, kutchulidwa kwa chiwerengerocho kumasiyananso.Ziyenera kutsimikiziridwa molingana ndi chiwerengero cha zigawo.Nthawi zambiri, kukopera bolodi lokhala ndi mbali ziwiri kumakhala kosavuta kuposa bolodi la multilayer, ndipo kulumikizana kwa bolodi la multilayer kumakhala kolakwika, kotero kukopera kwa board multilayer kuyenera kusamala komanso kusamala (momwe mkati kudzera m'dzenje ndi Ndikosavuta kukhala ndi vuto ndi mabowo odutsa).
Njira yokopera pa board ya mbali ziwiri:
1. Jambulani pamwamba ndi pansi pa bolodi lozungulira, ndikusunga zithunzi ziwiri za BMP.
2. Tsegulani mapulogalamu a bolodi, dinani "fayilo" ndi "mapu otsegula" kuti mutsegule chithunzi chojambulidwa.Kulitsani chinsalu ndi tsamba, onani pad, dinani PP kuti muyike pad, onani mzere, ndipo dinani PT kuti ayende Monga momwe mwana amajambula, jambulani kamodzi mu pulogalamuyo, ndipo dinani "sungani" kuti mupange fayilo ya B2P.
3. Dinani "fayilo" ndi "kutsegula pansi" kachiwiri kuti mutsegule mapu ojambulidwa amtundu wina;4. Dinani "fayilo" ndi "kutsegula" kachiwiri kutsegula fayilo ya B2P yosungidwa kale.Tikuwona bolodi lomwe langojambulidwa kumene, lomwe layikidwa pa chithunzichi - bolodi la PCB lomwelo, mabowo ali pamalo omwewo, koma kugwirizana kwa dera ndi kosiyana.Chifukwa chake timakanikiza "zosankha" - "Zikhazikiko Zosanjikiza", apa zimitsani kuzungulira ndi kusindikiza kwazenera kwa mawonekedwe apamwamba, ndikusiya ma vias amitundu yambiri.5. The vias pamwamba wosanjikiza ndi ofanana ndi amene ali pansi wosanjikiza.
Nkhani ndi zithunzi zochokera pa intaneti, ngati kuphwanya kulikonse pls lemberani kuti tifufute.
