Shenzhen Shinzo Technology Co., Ltd. ubu irimo kugura icyiciro gishya cyibikoresho byo gupima chip ya IC, kugerageza ibikoresho byerekana amashusho nkuko bigaragara muri iyi ngingo, ntabwo dushaka gukora akazi keza ka serivisi zitanga amasoko imwe gusa kubakiriya, ariko no kuri guha abakiriya bacu kwemeza ko chip ari shyashya kandi zumwimerere.Nintego yacu gukorera hamwe kugirango iterambere rirambye ryiterambere rya buriwese!
Chip ya IC Chip, Integrated Circuit Chip, nugushira umubare munini wibikoresho bya mikorobe (transistors, résistoriste, capacator, nibindi) byashizeho umuzenguruko uhuriweho na plastike, kugirango ukore chip.
Kugeza ubu, ubwiza bwa chip chip bugira uruhare runini mubicuruzwa byose bya elegitoroniki, bigira ingaruka kuburyo butaziguye ubwiza bwibicuruzwa byose nyuma yisoko.Noneho kubakozi bashinzwe gutanga amasoko, nigute ushobora kumenya neza ubwiza bwa chip chip?Iyi ngingo irerekana muri make uburyo bwinshi.

1. Kumenyekanisha kumurongo
Ubu buryo bukorwa mugihe IC idasuditswe mukuzunguruka.Muri rusange, multimeter irashobora gukoreshwa mugupima indangagaciro nziza kandi ihindagurika hagati yimipira ijyanye nubutaka, kandi IC imeze neza izagereranywa.

2. Kumenyekanisha kumurongo
(1) Kugaragaza DC birwanya, kimwe no gutahura umurongo
Ubu ni metero nyinshi zerekana ibyuma bya IC mumuzunguruko (IC mumuzunguruko) DC irwanya DC, voltage ya AC na DC kubutaka hamwe nuburyo rusange bwo gukora bwo kumenya.
(2) Gupima imbaraga za DC zikora
Ibi ni mubyerekeranye nimbaraga, hamwe na metero nyinshi DC yumuriro wa DC itanga voltage, ibice bya periferique yo gupima voltage ikora;Gerageza agaciro ka DC ya voltage ya buri IC pin hasi, hanyuma ugereranije nagaciro gasanzwe, hanyuma ugabanye urwego rwamakosa, mubice byangiritse.
Iyo upima, witondere ingingo umunani zikurikira:
MeterMetero nyinshi igomba kuba ifite imbere ihagije imbere, munsi yikubye inshuro 10 kurwanya umuzenguruko wapimwe, kugirango idatera ikosa rinini ryo gupimwa.
Ually Mubisanzwe potentiometero kumwanya wo hagati, niba ari TV, isoko yikimenyetso cyo gukoresha ibara risanzwe ryerekana amabara.
Reba ikaramu cyangwa iperereza kugirango ufate ingamba zo kurwanya skid.Kuberako akanya gato ako kanya byoroshye kwangiza IC.Uburyo bukurikira burashobora gufatwa kugirango wirinde kunyerera kw'ikaramu: fata igare hamwe na valve yibanze yashyizwe kumeza nib, hamwe nameza maremare nib hafi 05mm, bishobora gutuma ameza nib ihuza neza nikizamini, kandi irashobora irinde neza kunyerera, niyo yakubita ingingo iherekejwe ntabwo izunguruka.
HenIyo voltage ya pin idahuye nagaciro gasanzwe, igomba gusesengurwa ukurikije niba voltage ya pin igira uruhare runini mumikorere isanzwe ya IC hamwe nimpinduka zijyanye nizindi voltage ya pin, kugirango tumenye ubuziranenge bwa IC.
⑤IC pin voltage izaterwa nibice bya periferiya.Iyo ibice bya periferique bibaye bitemba, umuzunguruko mugufi, uruziga rufunguye cyangwa agaciro gahindagurika, cyangwa umuzenguruko wa periferiya uhujwe na variable potentiometre ihindagurika, umwanya wa potentiometero kunyerera ukuboko gutandukanye, bizatuma pin voltage ihinduka.
⑥Niba IC pin voltage isanzwe, IC ifatwa nkibisanzwe;Niba IC igice cya pin voltage idasanzwe, igomba guhera kumurongo ntarengwa uva kubiciro bisanzwe, reba ibice bya peripheri nta kosa bifite, niba nta kosa, IC ishobora kwangirika.
OrKu bikoresho byakira byakira, nka tereviziyo, iyo nta kimenyetso, voltage ya IC pin iratandukanye.Niba bigaragaye ko pin voltage idakwiye guhinduka ahubwo ihindure nini, hamwe nubunini bwikimenyetso hamwe nimyanya itandukanye yibintu bishobora guhinduka ariko ntibihinduke, ibyangiritse bya IC birashobora kugenwa.
OrKuburyo butandukanye bwo gukora bwibikoresho, nkibyafashwe amajwi, muburyo butandukanye bwo gukora, voltage ya IC pin nayo iratandukanye.

3. Uburyo bwo gukora voltage yo gukora
AC voltage igereranya ya IC ipimwa na multimeter hamwe na dosiye ya dB.Niba nta dosiye ya dB, irashobora kwinjizwa mumunwa imbere yikaramu.1-0.5. .
(Imikorere / Umuyoboro wa Waveform utabishaka)
4. Uburyo bwose bwo gupima
Mugupima igiteranyo cyamashanyarazi ya IC yose, dushobora gusuzuma ubwiza bwa IC.Bitewe nubwinshi bwa IC imbere DC ihuza, kwangirika kwa IC (nko guhuza PN guhuza cyangwa gufungura umuzenguruko) bizatera nyuma yicyambu cyahinduwe no guhagarikwa, kugirango impinduka zose zigezweho.Gupima rero ibyuzuye byose birashobora gusuzuma ubuziranenge bwa IC.Agaciro kagezweho karashobora kubarwa mugupima voltage kumurwanya wa loop.
