Murakaza neza kubuyobozi bwuzuye bwo kugenzura imbaho zumuzingo zacapwe (PCBs) hamwe na multimeter.Waba uri kwishimisha, ukunda ibikoresho bya elegitoroniki, cyangwa umunyamwuga, uzi gukoresha neza multimeter kugirango ugerageze PCB ni ngombwa mugukemura ibibazo no kwemeza kwizerwa kwimishinga yawe ya elegitoroniki.Muri iyi blog, tuzasobanura birambuye intambwe ku yindi inzira yo kugenzura neza PCB ukoresheje multimeter, iguha ubumenyi bwo kwerekana amakosa no gukora ibikenewe.
Wige ibijyanye na PCB n'ibiyigize:
Mbere yo kwibira mubikorwa, ni ngombwa kugira ubumenyi bwibanze kuri PCB nibiyigize.PCB ni urupapuro ruringaniye rwibikoresho bitayobora (ubusanzwe fiberglass) itanga ubufasha bwimashini hamwe nu mashanyarazi kubikoresho bitandukanye bya elegitoroniki.Ibi bice, nka résistoriste, capacator, diode, hamwe na sisitemu ihuriweho, byashyizwe kuri PCB ukoresheje inzira ziyobora bita traces.
Intambwe ya 1: Menya neza ko multimeter yashyizweho neza:
Gutangira ubugenzuzi bwa PCB, shyira multimeter muburyo bukwiye.Hindura kuri "Ohms" cyangwa "Resistance", kuko ibi bizadufasha gupima ubudahangarwa no guhangana kurubaho.Kandi, hindura igenamiterere ukurikije indangagaciro ziteganijwe zo guhangana uzahura na PCB.
Intambwe ya 2: Reba ubudahwema:
Kwipimisha ubudahwema bifasha kumenya ubusugire bwibisobanuro hamwe nabagurisha kuri PCB.Banza uzimye amashanyarazi kuri PCB.Ibikurikira, kora kuri multimeter yumukara numutuku kuri point ebyiri zitandukanye kumurongo cyangwa kugurisha hamwe.Niba multimeter ikubita cyangwa ikerekana zeru zeru, byerekana gukomeza, byerekana inzira nziza cyangwa ihuza.Niba nta beep cyangwa gusoma cyane birwanya gusoma, hariho uruziga rufunguye cyangwa ihuza ribi rigomba gusanwa.
Intambwe ya 3: Menya inzira ngufi:
Imirongo migufi akenshi niyo nyirabayazana yo gutsindwa kwa PCB.Kugirango ubamenye, shyira multimeter yawe kuri "diode".Kora kuri probe yumukara hasi, hanyuma ukore byoroheje probe itukura ahantu hatandukanye kuri PCB, cyane cyane hafi ya IC nibice bitanga ubushyuhe.Niba multimeter isoma hasi cyangwa beeps, byerekana umuzenguruko mugufi bisaba ko hakomeza kugenzurwa no gusanwa.
Intambwe ya 4: Gupima Kurwanya:
Kwipimisha birwanya bifasha kumenya ubusugire bwurwanya kuri PCB.Hitamo urwego rukwiye kuri multimeter kugirango bipime kurwanywa hanyuma ukore ku mpanuro ya probe kumpande zombi za résistor.Kurwanya ubuzima bwiza bigomba gutanga imbaraga muburyo bwo kwihanganira kugaragazwa namabara yabyo.Niba ibyasomwe bitarangiye, résistor irashobora gukenera gusimburwa.
Intambwe ya 5: Ubushobozi bwikizamini:
Ubushobozi ni ibintu byingenzi bikunze gutsindwa.Kugirango umenye imikorere yacyo, shyira multimeter kuri "capacitance".Menya ibintu byiza nibibi bya capacitori hanyuma ushire multimeter probe ukurikije.Multimeter izerekana ubushobozi bwa capacitance, ushobora kugereranya na capacitance yashyizwe kumurongo.Biragaragara ko indangagaciro zitandukanye zishobora kwerekana ubushobozi buke.
Ukurikije intambwe zavuzwe haruguru, urashobora gukoresha neza multimeter kugirango ugenzure kandi usuzume ibibazo kuri PCB.Wibuke ko kwihangana no kwibandaho ari ngombwa muriki gikorwa kugirango umenye neza ibisubizo kandi wirinde kwangirika.Mugaragaza neza amakosa, urashobora gutangira gusana ufite ikizere, koroshya imishinga ya elegitoroniki no kunoza ubuhanga bwawe bwo gukemura.Kwipimisha neza no gukosora!
