Ubwa mbere, amayeri mato yo kugerageza multimeter igerageza SMT
Ibice bimwe bya SMD ni bito cyane kandi ntibyoroshye kugerageza no gusana hamwe namakaramu asanzwe ya multimeter. Imwe ni uko byoroshye gutera uruziga rugufi, naho ubundi ni uko bitoroheye ikibaho cyumuzunguruko cyashizwe hamwe nigitambaro gikingira gukoraho igice cyicyuma cya pin. Hano hari inzira yoroshye yo kubwira abantu bose, bizazana byinshi byoroshye kubimenya.

Fata inshinge ebyiri ntoya zidoda, (Inkingi Yimbaraga Zigenzura Zifata Inganda), uzifunge hafi yikaramu ya multimeter, hanyuma ufate umugozi muto wumuringa uva mumigozi myinshi, hanyuma uhambire urushinge nurushinge hamwe, koresha umugurisha kuri ugurisha ashikamye. Muri ubu buryo, nta ngaruka zo kuzunguruka mugufi mugihe upimye ibyo bice bya SMT ukoresheje ikaramu yipimisha hamwe nuduce duto twa inshinge, kandi inshinge y'urushinge irashobora gutobora igifuniko gikingira kandi igakubita ibice byingenzi, bitabaye ngombwa ko uhagarika firime. .

Icya kabiri, uburyo bwo gufata neza ikibaho cyumuzunguruko rusange itanga amashanyarazi magufi
Mu kubungabunga ikibaho cyumuzunguruko, niba uhuye numuyoboro mugufi wamashanyarazi rusange, amakosa arakomeye, kuberako ibikoresho byinshi bisangiye amashanyarazi amwe, kandi igikoresho cyose gikoresha ayo mashanyarazi gikekwa ko kizunguruka gito. Niba nta bice byinshi biri ku kibaho, koresha “hoe isi” Nyuma ya byose, urashobora kubona aho bigarukira. Niba hari ibintu byinshi cyane, bizaterwa n'amahirwe yo "kuzunguruka isi" kugirango ugere kumiterere. Uburyo bwiza cyane burasabwa hano. Gukoresha ubu buryo bizabona ibisubizo kabiri hamwe nimbaraga zimbaraga kandi akenshi ushake amakosa vuba.

Birakenewe kugira amashanyarazi hamwe na voltage ishobora guhinduka hamwe nubu, voltage 0-30V, 0-3A y'ubu, aya mashanyarazi ntabwo ahenze, hafi 300. Hindura umuyagankuba ufunguye kumurongo wibikoresho bitanga amashanyarazi, banza uhindure umuyaga kugeza byibuze, ongeraho iyi voltage kumashanyarazi yumuriro wumurongo wumuzunguruko, nka 5V na 0V ya terefone ya 74 ya chip, bitewe na urwego rwumuzunguruko mugufi, ongera buhoro buhoro. Kora ku gikoresho ukoresheje intoki. Iyo ukoze ku gikoresho gishyuha cyane, ibi nibintu byangiritse, bishobora gukurwaho kugirango bipimwe kandi byemezwe. Birumvikana ko voltage itagomba kurenza imbaraga zumurimo wigikoresho mugihe gikora, kandi ihuriro ntirishobora guhinduka, bitabaye ibyo bizatwika ibindi bikoresho byiza.

Icya gatatu. Gusiba gato birashobora gukemura ibibazo bikomeye
Ibibaho byinshi kandi byinshi bikoreshwa mugucunga inganda, kandi imbaho ​​nyinshi zikoresha intoki za zahabu kugirango zinjire mumwanya. Bitewe n’ibidukikije bikaze by’inganda, umukungugu, ubushuhe, hamwe na gaze yangiza, inama y'ubutegetsi irashobora kunanirwa guhura. Inshuti zishobora kuba zarakemuye ikibazo mugusimbuza ikibaho, ariko ikiguzi cyo kugura ikibaho ni kinini cyane cyane ikibaho cyibikoresho bimwe byatumijwe hanze. Mubyukuri, ushobora no gukoresha gusiba kugirango ukure urutoki rwa zahabu inshuro nyinshi, usukure umwanda kurutoki rwa zahabu, hanyuma wongere ugerageze imashini. Ikibazo gishobora gukemuka! Uburyo buroroshye kandi bufatika.

Kugera. Isesengura ry'amakosa y'amashanyarazi mubihe byiza n'ibihe bibi
Kubijyanye nibishoboka, amakosa y'amashanyarazi atandukanye hamwe nibihe byiza nibibi arimo ibihe bikurikira:
1. Guhuza nabi
Guhuza nabi hagati yubuyobozi nu mwanya, mugihe umugozi wacitse imbere, ntabwo bizakora, icyuma na terefone ntigihuza, nibice bigurishwa.
2. Ikimenyetso kivanze
Kumurongo wa sisitemu, amakosa azagaragara gusa mubihe runaka. Birashoboka ko kwivanga cyane byagize ingaruka kuri sisitemu yo kugenzura no guteza amakosa. Hariho kandi impinduka mubice bigize ibice cyangwa imikorere rusange yibikorwa byumuzunguruko kugirango wirinde kwivanga. Ubushobozi bukunda ingingo ikomeye, biganisha ku gutsindwa;
3. Ubushyuhe buke bwubushyuhe bwibigize
Uhereye ku mubare munini wibikorwa byo kubungabunga, ubushyuhe bwumuriro wa capacitori ya electrolytike niyambere mubukene, hagakurikiraho izindi capacator, triode, diode, IC, résistoriste, nibindi.;
4. Ubushuhe n'umukungugu kurubaho.
Ubushuhe hamwe n ivumbi bizayobora amashanyarazi kandi bigira ingaruka zo guhangana, kandi agaciro kokurwanya kazahinduka mugihe cyo kwagura ubushyuhe no kugabanuka. Agaciro ko kurwanya kazagira ingaruka zingana nibindi bice. Iyo iyi ngaruka ikomeye, izahindura ibipimo byumuzunguruko kandi itere imikorere mibi. bibaho;
5. Porogaramu nayo ni kimwe mubitekerezo
Ibipimo byinshi mumuzunguruko byahinduwe na software. Impera y'ibipimo bimwe byahinduwe hasi cyane kandi biri murwego rukomeye. Mugihe imikorere yimashini ihuye nimpamvu za software kugirango tumenye kunanirwa, noneho impuruza izagaragara.

Icya gatanu, uburyo bwo kubona byihuse amakuru yibigize
Ibicuruzwa bya elegitoroniki bigezweho biratandukanye, kandi ubwoko bwibigize buragenda butandukana. Mu kubungabunga umuzunguruko, cyane cyane mubijyanye no gufata neza inganda zumuzunguruko, ibice byinshi ntibiboneka cyangwa ntibigeze byunvikana. Mubyongeyeho, nubwo amakuru yibigize ku kibaho runaka yuzuye, Ariko niba ushaka gushakisha no gusesengura aya makuru umwe umwe muri mudasobwa yawe, niba nta buryo bwo gushakisha bwihuse, imikorere yo kubungabunga izagabanuka cyane. Mu rwego rwo gufata neza ibikoresho bya elegitoroniki, gukora neza ni amafaranga, kandi gukora neza ni amafaranga yo mu mufuka.
