Shenzhen Shinzo Technology Co., Ltd. tsopano akugula mtanda watsopano wa IC chipangizo chipangizo kuyezetsa zipangizo, kuyezetsa zipangizo zithunzi monga taonera m'nkhani ino, ife osati amafuna kuchita ntchito yabwino ya ntchito imodzi amasiya zogula kwa makasitomala, komanso perekani makasitomala athu kuti awonetsetse kuti tchipisi ndi zatsopano komanso zoyambirira.Cholinga chathu ndi kugwirira ntchito limodzi kuti titukule makampani amtundu wina!
IC Chip, Integrated Circuit Chip, ndikuyika zigawo zambiri za microelectronic (transistors, resistors, capacitors, etc.) anapanga dera lophatikizika pazitsulo zapulasitiki, kuti apange chip.
Pakalipano, khalidwe la IC chip limagwira ntchito yaikulu kwambiri pazinthu zonse zamagetsi, zomwe zimakhudza mwachindunji ubwino wa chinthu chonsecho pambuyo pa msika.Ndiye kwa ogwira ntchito zogula zinthu, mungazindikire bwanji mtundu wa IC chip?Nkhaniyi ikufotokoza mwachidule njira zingapo.

1. Kuzindikira popanda intaneti
Njira imeneyi ikuchitika pamene IC si welded mu dera.Kawirikawiri, multimeter ingagwiritsidwe ntchito kuyeza zotsutsa zabwino ndi zotsutsana pakati pa zikhomo zomwe zimagwirizana ndi zikhomo za pansi, ndipo IC ili bwino idzafanizidwa.

2. Kuzindikira pa intaneti
(1) Kuzindikira kukana kwa DC, mofanana ndi kuzindikira kunja kwa intaneti
Uku ndikuzindikira kwamamita angapo a ma IC pins mudera (IC mu dera) DC kukana, AC ndi DC voliyumu pansi ndi njira yonse yodziwira yomwe ikugwira ntchito.
(2) Kuyeza kwa magetsi a DC ogwira ntchito
Izi ndi nkhani ya mphamvu, ndi Mipikisano mita DC voteji chipika DC magetsi voteji, zotumphukira zigawo zikuluzikulu za ntchito voteji kuyeza;Yesani mtengo wa voteji wa DC wa pini iliyonse ya IC mpaka pansi, ndikuyerekeza ndi mtengo wabwinobwino, ndiyeno sungani molakwika, kuchokera pazida zowonongeka.
Poyeza, tcherani khutu ku mfundo zisanu ndi zitatu izi:
①Mamita ambiri ayenera kukhala ndi kukana kokwanira mkati, kuchepera nthawi 10 kukana kwa dera loyezedwa, kuti asapangitse cholakwika chachikulu.
②Kawirikawiri potentiometer kwa malo apakati, ngati ndi TV, gwero chizindikiro ntchito muyezo mtundu bala chizindikiro jenereta.
③ yang'anani cholembera kapena kufufuza kuti mutenge njira zotsutsana ndi skid.Chifukwa dera lalifupi lililonse ndilosavuta kuwononga IC.Njira zotsatirazi zingatengedwe kuti mupewe kutsetsereka kwa cholembera: tengani njinga yokhala ndi valavu pachimake pa tebulo nib, ndi tebulo lalitali pafupifupi 05mm, zomwe zingapangitse tebulo kukhudzana bwino ndi malo oyesera, bwino kupewa kutsetsereka, ngakhale kugunda malo oyandikana sadzakhala dera lalifupi.
④Pamene voteji ya pini sikugwirizana ndi mtengo wamba, iyenera kuwunikidwa molingana ndi ngati magetsi a pini ali ndi chikoka pa ntchito yachibadwa ya IC ndi kusintha kofanana kwa magetsi ena a pini, kuti athe kuweruza ubwino wa pini. KODI.
⑤IC pin voltage idzakhudzidwa ndi zigawo zotumphukira.Pamene zigawo zotumphukira zimachitika kutayikira, dera lalifupi, lotseguka dera kapena mtengo variable, kapena zotumphukira dera chikugwirizana variable kukana potentiometer, malo a potentiometer kutsetsereka mkono ndi osiyana, adzapanga pini voteji kusintha.
⑥Ngati magetsi a IC pin ali abwinobwino, IC nthawi zambiri imawonedwa ngati yabwinobwino;Ngati gawo la IC la pini voteji ndi lachilendo, liyenera kuyamba kuchokera pakupatuka kwakukulu kuchokera kumtengo wamba, fufuzani kuti zigawo zotumphukira zilibe cholakwika, ngati palibe cholakwika, IC ikhoza kuwonongeka.
⑦ Pazida zolandirira zamphamvu, monga wailesi yakanema, ngati palibe chizindikiro, IC pin voltage ndi yosiyana.Zikapezeka kuti magetsi a pini sayenera kusintha koma kusintha kwakukulu, ndi kukula kwa siginecha ndi malo osiyanasiyana azinthu zosinthika koma osasintha, kuwonongeka kwa IC kungadziwike.
⑧ Pazida zosiyanasiyana zogwirira ntchito, monga zojambulira makanema, m'njira zosiyanasiyana zogwirira ntchito, IC pin voltage ndiyosiyananso.

3. Njira yoyesera yamagetsi ya Ac ntchito
Kuyerekeza kwamagetsi a AC kwa IC kumayesedwa ndi multimeter yokhala ndi fayilo ya dB.Ngati palibe fayilo ya dB, imatha kulowetsedwa mkamwa kutsogolo kwa cholembera.1-0.5 "kudzipatula kwa mphamvu ya DC. Chitsanzochi chikugwiritsidwa ntchito kwa omwe ali ndi maulendo otsika kwambiri. Koma dziwani kuti zizindikirozi zidzakhudzidwa ndi maulendo achilengedwe ndipo zidzasiyana ndi mawonekedwe a mafunde. .

4. Njira yonse yoyezera pano
Poyesa kuchuluka kwa magetsi a IC, titha kuweruza mtundu wa IC.Chifukwa cha kuphatikizika kwa IC mkati mwa DC, kuwonongeka kwa IC (monga kuwonongeka kwa PN makulidwe kapena kutseguka kozungulira) kumayambitsa doko lolowera ndikudulidwa, kotero kuti kusintha konse komwe kulipo.Chifukwa chake kuyeza kuchuluka kwapano kumatha kuweruza mtundu wa IC.Mtengo wamakono ukhoza kuwerengedwa poyesa voteji pa kukana kwa loop.
