Pakafukufuku wa PCB teknoloji yobwezera, chiwonetsero chazithunzi chosunthira chimatanthawuza chithunzi cha fayilo ya PCB kapena chithunzithunzi cha PCB chojambulidwa molingana ndi chinthu chomwe chimapangidwacho, kuti afotokozere momwe zimakhalira ndi dera lomwe likugwira ntchito. Kuphatikiza apo, chithunzichi chimagwiritsidwanso ntchito kupenda magwiridwe antchito a chinthucho. Patsogolo, kapangidwe kazinthu zonse ziyenera kuyamba kupanga masanjidwe, kenako ndikupanga ma PCB malinga ndi mapulani.

Makina a PCB ali ndi gawo lapadera, kaya amagwiritsidwa ntchito kupenda mfundo zama board ndi mawonekedwe azogwiritsira ntchito pakuphunzira mosalekeza, kapena ngati maziko ndi maziko a kapangidwe ka PCB pakapangidwe kutsogolo. Kotero, momwe mungasinthire dongosolo la PCB, ndipo ndizinthu ziti zomwe njira yotsatirayo iyenera kuyang’anira, kutengera zolemba kapena zinthu zenizeni?

1. Gawani moyenera magwiridwe antchito

Pomwe chithunzi cha board ya PCB chapangidwanso, magawano oyenera amalo ogwira ntchito amatha kuthandiza akatswiri kuthana ndi mavuto osafunikira ndikuwongolera bwino zojambula.Mwambiri, zigawo zikuluzikulu zokhala ndi ntchito yofananira pa PCB zidzakonzedwa m’njira yapakatikati, ndipo gawo logwirira ntchito limatha kukhala ndi maziko oyenera komanso olondola pomwe chiwembu chimasinthidwa. Komabe, kugawidwa kwa malo ogwira ntchitowa sikungosinthasintha. Zimafunikira akatswiri kuti amvetsetse zina zamagetsi zamagetsi zamagetsi. Choyamba, fufuzani zigawo zikuluzikulu zomwe zimagwira ntchito, kenako malingana ndi kulumikizana kwakatundu, fufuzani zigawo zina za chinthu chomwecho, ndikupanga magawano ogwira ntchito. Mapangidwe azigawo zogwirira ntchito ndiye maziko amachitidwe. Komanso, musaiwale kugwiritsa ntchito manambala osanjikiza pa bolodi panthawiyi, zomwe zingakuthandizeni kugawa magwiridwe antchito mwachangu.

2. Pezani miyeso yolinganizira

Izi zitha kunenedwa kuti ndiye gawo lalikulu la bolodi ya PCB kumayambiriro kwa zojambula. Magawo ofotokozerawo akazindikirika, kujambula malinga ndi zikhomo zamagawo ofotokozerawa kumatha kutsimikizira kulongosola kwadongosolo kwambiri. Kukhazikika kwa gawo lofotokozedwalo silovuta kwambiri kwa akatswiri. Nthawi zambiri, gawo lomwe limagwira gawo lalikulu m’deralo limatha kusankhidwa ngati gawo lofotokozera. Nthawi zambiri zimakhala zazikulu ndipo zimakhala ndi zikhomo zambiri, zomwe ndizosavuta kutambasula. Monga ma circuits ophatikizika, ma thiransifoma, ma transistor, ndi zina zambiri, zitha kukhala zowunikira koyenera.

3, kusiyanitsa molondola mizere, mzere wololera

Pofuna kusiyanitsa mizere yapansi, yamagetsi ndi yamagetsi, akatswiri amafunikanso kudziwa zamagetsi, kulumikizana kwa dera, kulumikizana kwa PCB ndi zina zambiri. Kusiyanitsa pakati pa mawayawa kumatha kusanthuledwa kuchokera kulumikizidwe kwa zinthu, kukula kwa zojambulazo zamkuwa mdera, komanso mawonekedwe amagetsi okha. Pazithunzi zazingwe, mawaya apansi amatha kugwiritsidwa ntchito pazizindikiro zambiri zapansi kuti mupewe kuwoloka ndikubalalika. Mizere imatha kusiyanitsidwa bwino pogwiritsa ntchito mizere yosiyanasiyananso, ndipo zizindikilo zapadera zitha kugwiritsidwa ntchito pazinthu zosiyanasiyana, ndipo ngakhale ma circuits amodzi amatha kujambulidwa payokha ndipo pamapeto pake amaphatikizidwa.

4. Phunzirani chimango ndikutanthauzira zithunzi zofanana

Pazinthu zina zoyendera zamagetsi zamagetsi ndi njira zojambula, mainjiniya amafunika kudziwa, osati kungokoka mwachindunji zigawo zina zosavuta komanso zachikale, komanso amapanga chimango cha magetsi. Kumbali inayi, musanyalanyaze zinthu zamagetsi zomwezo mu PCB zojambula zojambulajambula zomwe zili ndi kufanana kwake. Akatswiri amatha kugwiritsa ntchito njira zofananira momwe angapangire zatsopano zamankhwala potengera zomwe akumana nazo.

5. Onetsetsani ndikukwaniritsa

Mukamaliza mwatsatanetsatane, muyenera kusintha mapangidwe a PCB poyesa ndikuyang’ana maulalo. Makhalidwe azinthu zomwe zimakhudzidwa ndi magawidwe a PCB amafunika kufufuzidwa ndikukwaniritsidwa. Malinga ndi kujambula kwa fayilo ya PCB, chojambula choyerekeza chikuyerekeza ndikufufuza kuti zitsimikizidwe kuti zojambula zomwezo ndizofanana ndendende kujambula. Ngati masanjidwewo atapezeka kuti sakukwaniritsa zofunikira pakuwunika, chiwembucho chidzasinthidwa mpaka zitakhala zomveka, zovomerezeka, zolondola komanso zomveka.
