I-Shenzhen Shinzo Technology Co., Ltd. manje ithenga iqoqo elisha lemishini yokuhlola i-IC chip, izithombe zemishini yokuhlola njengoba kukhonjisiwe kulesi sihloko, asifuni nje ukwenza umsebenzi omuhle wezinsizakalo zokuthenga okukodwa kumakhasimende, kodwa futhi sinikeze amakhasimende ethu ukuthi aqinisekise ukuthi ama-chips masha futhi awangempela.Kuyinhloso yethu ukusebenzelana ekuthuthukisweni kwesikhathi eside kwezinkampani zomunye nomunye!
I-IC Chip, I-Integrated Circuit Chip, iwukubeka inani elikhulu lezingxenye ze-microelectronic (ama-transistors, resistors, capacitor, njll.) yakhe isekethe ehlanganisiwe esisekelweni sepulasitiki, ukuze kwenziwe i-chip.
Njengamanje, ikhwalithi ye-IC chip idlala indima enkulu kakhulu kuyo yonke imikhiqizo ye-elekthronikhi, ethinta ngokuqondile ikhwalithi yawo wonke umkhiqizo ngemva kwemakethe.Ngakho-ke kubasebenzi bokuthenga, bangayithola kanjani kahle ikhwalithi ye-IC chip?Lesi sihloko sethula kafushane izindlela ezimbalwa.

1. Ukutholwa ungaxhunyiwe ku-inthanethi
Le ndlela yenziwa lapho i-IC ingashiselwe kusekethe.Ngokuvamile, i-multimeter ingasetshenziswa ukukala amanani okumelana okuhle nokuhlehla phakathi kwezikhonkwane ezihambisana nezikhonkwane zomhlabathi, futhi i-IC esesimweni esihle izoqhathaniswa.

2. Ukutholwa ku-inthanethi
(1) Ukutholwa kokumelana kwe-DC, okufanayo nokutholwa ungaxhunyiwe ku-inthanethi
Lokhu ukutholwa kwamamitha amaningi wamaphini e-IC kusekethe (IC kusekethe) ukumelana ne-DC, i-AC kanye ne-DC voltage phansi kanye nesamba sendlela yokutholwa yamanje esebenzayo.
(2) Ukukalwa kwe-voltage esebenzayo ye-DC
Lena endabeni yamandla, ene-multi-meter DC voltage block DC supply voltage, izingxenye ze-peripheral zesilinganiso se-voltage yokusebenza;Hlola inani le-voltage ye-DC yephinikhodi ngayinye ye-IC ukuya phansi, futhi uma kuqhathaniswa nevelu evamile, bese ucindezela ububanzi bephutha, ngaphandle kwezingxenye ezilimele.
Lapho ukala, naka amaphuzu ayisishiyagalombili alandelayo:
①Amamitha amaningi kufanele abe nokumelana okwanele kwangaphakathi, okungaphansi kwezikhathi ezingu-10 ukumelana kwesekethe elinganisiwe, ukuze angabangeli iphutha elikhulu lokulinganisa.
②Imvamisa i-potentiometer eya endaweni emaphakathi, uma kuyi-TV, umthombo wesiginali wokusebenzisa isignali yebha yombala ejwayelekile.
③buka ipeni noma ukuhlola ukuze uthathe izinyathelo zokulwa nokushushuluza.Ngoba noma iyiphi isifunda esifushane esisheshayo kulula ukulimaza i-IC.Izindlela ezilandelayo zingathathwa ukuvimbela ukushelela kwepeni: thatha ibhayisikili elinomgogodla we-valve osethelwe phezu kwetafula, kanye ne-table nib ende engaba ngu-05mm, engenza ithebula lithinte kahle iphuzu lokuhlola, futhi lingakwazi ukuvimbela ngempumelelo ukushelela, ngisho noma hit iphuzu eliseduze ngeke isifunda iDemo.
④Lapho i-voltage yephinikhodi ingahambisani nevelu evamile, kufanele ihlaziywe ngokuya ngokuthi amandla kagesi ephinikhodi anethonya elibalulekile ekusebenzeni okuvamile kwe-IC kanye nezinguquko ezihambisanayo zamanye amandla kagesi wephinikhodi, ukuze kwahlulelwe ikhwalithi yephinikhodi. IC.
⑤IC pin voltage izothintwa izingxenye ze-peripheral.Lapho izingxenye ze-peripheral zenzeka ukuvuza, isifunda esifushane, isekethe evulekile noma inani eliguquguqukayo, noma isifunda se-peripheral sixhunywe ku-potentiometer yokumelana eguquguqukayo, indawo yengalo eshelelayo ye-potentiometer ihlukile, izokwenza ukuthi i-pin voltage ishintshe.
⑥Uma i-IC pin voltage ijwayelekile, i-IC ngokuvamile ithathwa njengejwayelekile;Uma ingxenye ye-IC ye-voltage yephinikhodi ingavamile, kufanele iqale kusukela ekuphambukeni okuphezulu kusuka kunani elivamile, hlola izingxenye ze-peripheral azinalo iphutha, uma kungenaphutha, i-IC ingase yonakaliswe.
⑦ Kumadivayisi aguqukayo amukelayo, njengomabonakude, uma ingekho isignali, i-IC pin voltage ihlukile.Uma kutholakala ukuthi ugesi wephinikhodi akufanele ushintshe kodwa ushintshe ube mkhulu, ngosayizi wesignali kanye nezindawo ezihlukene zesici esilungisekayo kodwa ungashintshi, umonakalo we-IC unganqunywa.
⑧Ezinhlobonhlobo zemodi yokusebenza yamadivayisi, njengeziqopha-vidiyo, ngezindlela ezihlukene zokusebenza, i-IC pin voltage nayo ihlukile.

3. Indlela yokuhlola i-voltage esebenzayo ye-Ac
I-AC voltage approximation ye-IC ikalwa nge-multimeter enefayela le-dB.Uma lingekho ifayela le-dB, lingafakwa emlonyeni phambi kwepeni.1-0.5 "ukuhlukaniswa komthamo we-DC. Le phethini isebenza kulabo abanamaza okusebenza aphansi. Kodwa qaphela ukuthi lawa masignali azoba ngaphansi kwamafrikhwensi emvelo futhi azohluka ukusuka kufomethi yegagasi ukuya kumagagasi. Ngakho-ke idatha elinganiselwe iyivelu elinganiselwe, njengereferensi kuphela .

4. Isamba sendlela yokulinganisa yamanje
Ngokulinganisa inani lamanje lokuphakelwa kukagesi we-IC, singahlulela ikhwalithi ye-IC.Ngenxa yobuningi bokuhlangana kwe-IC kwangaphakathi kwe-DC, ukulimala kwe-IC (njengokuhlukana kwe-PN junction noma isekethe evulekile) kuzodala ngemva kwembobo ehlanekezelwe kanye nokunqanyulwa, ukuze ingqikithi yamanje ishintshe.Ngakho ukulinganisa inani lamanje kungahlulela ikhwalithi ye-IC.Inani lamanje lingabalwa ngokulinganisa i-voltage ekuphikisaneni kwe-loop.
