Weiwenxin PCBworld] Mu kafukufuku wa PCB n'zosiyana teknoloji, n'zosiyana kukankhira mfundo amatanthauza m'mbuyo kukankhira kunja malinga PCB chikalata chojambula kapena mwachindunji kujambula PCB dera chithunzi malinga ndi mankhwala enieni, amene cholinga chake ndi kufotokoza mfundo ndi chikhalidwe ntchito dera. bolodi.Kuphatikiza apo, chithunzi chozungulirachi chimagwiritsidwanso ntchito kusanthula magwiridwe antchito a chinthucho chokha.Mu mapangidwe patsogolo, ambiri mankhwala chitukuko ayenera choyamba kuchita kamangidwe schematic, ndiyeno kuchita PCB kapangidwe malinga ndi schematic.
Kaya imagwiritsidwa ntchito kusanthula mfundo za board board ndi mawonekedwe ogwiritsira ntchito mankhwala pofufuza m'mbuyo, kapena imagwiritsidwanso ntchito ngati maziko ndi maziko a mapangidwe a PCB pamapangidwe amtsogolo, ma schematics a PCB ali ndi gawo lapadera.Ndiye, momwe mungasinthire chithunzi cha PCB potengera chithunzi kapena chinthu chenicheni?Kodi ndi mfundo ziti zomwe ziyenera kutsatiridwa powerengera m'mbuyo?
Kugawanika koyenera kwa madera ogwira ntchito
01
Popanga mawonekedwe osinthika a pulojekiti yabwino ya PCB yozungulira, kugawikana koyenera kwa madera ogwirira ntchito kungathandize mainjiniya kuchepetsa zovuta zina zosafunikira ndikuwongolera luso la kujambula.Nthawi zambiri, zigawo zomwe zili ndi ntchito yofanana pa bolodi la PCB zimakonzedwa mokhazikika, ndipo kugawa madera ndi ntchito kumatha kukhala ndi maziko osavuta komanso olondola potembenuza chithunzi cha schematic.
Komabe, kugawanika kwa malo ogwira ntchitowa sikungokhalira.Zimafunikira mainjiniya kukhala ndi chidziwitso chokhudza chidziwitso chamagetsi.Choyamba, pezani gawo lalikulu mu gawo linalake logwira ntchito, ndiyeno molingana ndi kulumikizana kwa waya, mutha kupeza zigawo zina zamagawo omwewo panjira kuti mupange gawo logwira ntchito.Mapangidwe a magawo ogwira ntchito ndi maziko a zojambula zokhazikika.Kuphatikiza apo, pochita izi, musaiwale kugwiritsa ntchito manambala amtundu wa zigawo zomwe zili pa bolodi ladera mwanzeru, zitha kukuthandizani kugawa ntchito mwachangu.
Kusiyanitsa mizere molondola ndi kujambula mawaya moyenera
02
Pakusiyanitsa pakati pa mawaya apansi, mawaya amagetsi, ndi mawaya azizindikiro, mainjiniya amafunikiranso kukhala ndi chidziwitso choyenera chamagetsi, chidziwitso cholumikizira dera, chidziwitso cha waya cha PCB, ndi zina zotero.Kusiyanitsa kwa mizere iyi kungathe kufufuzidwa pokhudzana ndi kugwirizana kwa zigawo, m'lifupi mwa zojambulazo zamkuwa za mzerewu, ndi zizindikiro za mankhwala amagetsi okha.
Muzojambula zamawaya, pofuna kupewa kuwoloka ndi kulowetsa mizere, zizindikiro zambiri zapansi zingagwiritsidwe ntchito pamzere wapansi.Mizere yosiyanasiyana imatha kugwiritsa ntchito mitundu yosiyanasiyana komanso mizere yosiyana kuti iwonetsetse kuti ndi yomveka komanso yodziwika bwino.Pazigawo zosiyanasiyana, zizindikiro zapadera zingagwiritsidwe ntchito, kapena Jambulani mabwalo amagawo padera ndikuphatikiza kumapeto.
Pezani zigawo zolondola
03
Gawo lolozerali likhoza kunenedwanso kuti ndilo gawo lalikulu lomwe limagwiritsidwa ntchito kumayambiriro kwa zojambulajambula.Gawo lolozeralo litatsimikiziridwa, gawo lolozera limakokedwa molingana ndi zikhomo za zigawo zolozerazi, zomwe zingatsimikizire kulondola kwa chojambulacho mokulirapo.
Kwa mainjiniya, kutsimikiza kwa magawo ofotokozera si nkhani yovuta kwambiri.Pazochitika zachilendo, zigawo zomwe zimagwira ntchito yaikulu mu dera zingasankhidwe ngati zidziwitso.Nthawi zambiri amakhala okulirapo ndipo amakhala ndi mapini ambiri, omwe ndi osavuta kujambula.Monga mabwalo ophatikizika, ma transistors, ma transistors, ndi zina zotere, zitha kugwiritsidwa ntchito ngati magawo oyenera ofotokozera.
Phunzirani zoyambira ndikuphunzira kuchokera pazithunzi zofananira
04
Pazinthu zina zoyambira zamagetsi zamagetsi zamagetsi ndi njira zojambulira, mainjiniya amayenera kukhala aluso, osati kuti athe kujambula mwachindunji mabwalo osavuta komanso apamwamba, komanso kupanga mawonekedwe onse amagetsi amagetsi.
Kumbali inayi, musanyalanyaze kuti mtundu womwewo wa zinthu zamagetsi zimakhala ndi zofanana muzithunzi za schematic.Mainjiniya atha kugwiritsa ntchito luso lochulukirachulukira ndikuphunzira kwathunthu kuchokera pazithunzi zofananira zofananira kuti asinthe mawonekedwe azinthu zatsopano.
Chongani ndi kukhathamiritsa
05
Zojambula zikamalizidwa, mapangidwe osinthika a PCB anganenedwe kuti amamaliza kuyesedwa ndi kutsimikizira.Mtengo wazinthu zomwe zimakhudzidwa ndi magawo ogawa a PCB uyenera kufufuzidwa ndikuwongoleredwa.Malinga ndi chithunzi cha fayilo ya PCB, chithunzi chazithunzi chimafaniziridwa ndikuwunikidwa kuti zitsimikizire kuti chithunzi chazithunzi chikugwirizana kwathunthu ndi chithunzi cha fayilo.
