Siyakwamukela futhi, abathandi bezobuchwepheshe kanye nabathandi be-DIY! Namuhla, ukugxila kwethu kumabhodi e-PCB, okungukuthi, amabhodi wesifunda aphrintiwe. Lezi zingxenye ezincane kodwa ezibalulekile zisenhliziyweni yezinto eziningi zikagesi futhi zinesibopho sokuqinisekisa ukuthi zisebenza ngendlela efanele. Kungakhathaliseki ukuthi ungunjiniyela ochwepheshe noma umuntu wokuzilibazisa, ukwazi ukuthi ulihlola kanjani ibhodi le-PCB kubalulekile ekuxazululeni izinkinga nasekugcineni okokusebenza kukagesi. Ngakho-ke, ake singene ezinyathelweni ezidingekayo ukuze sihlole futhi siqinisekise ukwethembeka kwebhodi le-PCB!
1. Ukuhlola okubonakalayo:
Isinyathelo sokuqala sokuhlola i-PCB ukwenza ukuhlola okubonakalayo okuphelele. Hlola ibhodi lesifunda ukuze uthole noma yimuphi umonakalo obonakalayo, njengokugqwala, izingxenye ezishile, noma ukuxega okuxhumekile. Bheka izimpawu zokuphuka noma zokulimala, izingxenye ezingaqondani kahle, noma izimpawu zokushisa ngokweqile. Ukuhlola okubukwayo kungase kubonakale kulula, kodwa kungasiza ukukhomba ngokuphumelelayo izinkinga ezingase zibe khona.
2. Ukuhlolwa kwengxenye:
Ngemva kokuhlola okubonakalayo, qhubeka uhlole ingxenye ngayinye ebhodini le-PCB. Qala ngokuqinisekisa ukuthi zonke izingxenye zifakiwe, ziqondaniswe, futhi zithengiswe ngendlela efanele. Sebenzisa i-multimeter ukukala ukumelana nokuqhubeka kwama-capacitor, resistors, nezinye izakhi zikagesi. Naka ukunaka okukhethekile ezingxenyeni ezingase zithambekele ekuhlulekeni, njengama-capacitor aneziqongo eziphumela ngaphandle noma ama-resistors ashisiwe.
3. Amandla ekuhlolweni:
Uma ukuhlola okubonakalayo nokuhlolwa kwengxenye sekuqediwe, sekuyisikhathi sokwenza ukuhlolwa kwamandla. Xhuma ibhodi le-PCB kumthombo wamandla onokwethenjelwa ngokuya ngemininingwane yomkhiqizi. Gada ibhodi lakho lomama ngokuziphatha okungajwayelekile, okufana nokushisa ngokweqile, ukubhema, noma ukuvala shaqa kungazelelwe. Sicela uqaphele ukuthi ungathinti noma yiziphi izingxenye ngenkathi ibhodi ivuliwe, njengoba ama-voltage aphezulu angase abangele ingozi yokushaqeka.
4. Ukuhlolwa kwesignali:
Ngokungeziwe ekuhloleni amandla, amasiginali athunyelwe futhi atholwe yibhodi le-PCB kumele nawo ahlolwe. Sebenzisa i-oscilloscope ukuze uqaphe amasignali okukhiphayo kanye namazinga kagesi futhi uwaqhathanise nezicaciso ezidingekayo. Qinisekisa ukuthi isignali izinzile ngaphandle kokuhlanekezela noma ukushintshashintsha. Lesi sinyathelo sibalulekile, ikakhulukazi kumabhodi e-PCB ayinkimbinkimbi lapho izingxenye eziningi zixhumana khona.
5. Ukuhlola okusebenzayo:
Ukuze uqinisekise ukusebenza kahle kwebhodi le-PCB, kubalulekile ukwenza ukuhlola okusebenzayo. Xhuma ibhodi kudivayisi efanele esebenza kuyo, njengemoto noma inzwa. Hlola ukuthi ibhodi le-PCB lenza umsebenzi walo ngendlela efanele yini. Qinisekisa ukuthi ubudlelwano bokufakwayo nokuphumayo bunembile nokuthi konke ukusebenza kusebenza njengoba kulindelekile. Lesi sinyathelo singase sidinge okokusebenza okuthuthuke kakhulu okufana ne-logic analyzer noma i-function generator, kuye ngobunkimbinkimbi bebhodi le-PCB.
Siyakuhalalisela! Ngokulandela izinyathelo ezingenhla, ufunde ukuthi ungahlola kanjani ukusebenza nokusebenza kwebhodi lakho le-PCB. Khumbula, ukuhlola okunembile kubalulekile ukuze uqinisekise ukuthi okokusebenza kwe-elekthronikhi kusebenza kahle nangokuthembekile. Uma kuphakama izinkinga ngesikhathi sokuhlolwa, ukuqonda imbangela kuyisinyathelo sokuqala sokuxazulula inkinga. Esimeni somonakalo omkhulu noma izinkinga eziyinkimbinkimbi, funa usizo lochwepheshe kochwepheshe be-PCB noma ochwepheshe bokukhanda izinto zikagesi ngokushesha. Hlala unelukuluku lokwazi, qhubeka ufunda, futhi ujabulele izivivinyo zebhodi le-PCB!
