I-Shenzhen Shinzo Technology Co., Ltd. ngoku ithenga ibhetshi entsha yezixhobo zovavanyo lwe-IC chip, izixhobo zokuvavanya imifanekiso njengoko kubonisiwe kweli nqaku, asifuni nje ukwenza umsebenzi olungileyo weenkonzo zokuthengwa kwempahla enye kubathengi, kodwa nokuba nika abathengi bethu ukuqinisekisa ukuba iitshiphusi zintsha kwaye ziqala.Yinjongo yethu ukusebenza kunye kuphuhliso lwexesha elide lweenkampani zomnye nomnye!
I-IC Chip, i-Integrated Circuit Chip, kukubeka inani elikhulu lamacandelo e-microelectronic (i-transistors, resistors, capacitors, njl.) Yakha isiphaluka esidibeneyo kwisiseko seplastiki, ukwenzela ukuba wenze i-chip.
Okwangoku, umgangatho we-IC chip udlala indima enkulu kakhulu kuzo zonke iimveliso ze-elektroniki, ezichaphazela ngokuthe ngqo umgangatho wemveliso yonke emva kokuthengisa.Ke kubasebenzi bokuthengwa kwempahla, indlela yokubona ngokuchanekileyo umgangatho we-IC chip?Eli nqaku lazisa ngokufutshane iindlela ezininzi.

1. Ukufunyanwa ngaphandle kwe-intanethi
Le ndlela iqhutyelwa xa i-IC ingafakwanga kwisiphaluka.Ngokuqhelekileyo, i-multimeter ingasetyenziselwa ukulinganisa ixabiso elichanekileyo kunye nokubuyisela umva phakathi kwezikhonkwane ezihambelana nezikhonkwane zomhlaba, kunye ne-IC esemgangathweni iya kuthelekiswa.

2. Ukufunyanwa kwi-Intanethi
(1) Ukufumanisa ukuxhathisa kwe-DC, kufana nokufunyanwa ngaphandle kwe-line
Oku kukufumanisa kweemitha ezininzi ze-IC izikhonkwane kwisekethe (IC kwisekethe) ukuxhathisa kwe-DC, i-AC kunye ne-DC voltage ukuya kumhlaba kunye nendlela yokufumanisa yokusebenza ngoku iyonke.
(2) Umlinganiselo wombane osebenzayo weDC
Oku kukwimeko yamandla, kunye ne-multi-meter DC ibloko yombane wombane we-DC wobonelelo lombane, amacandelo eperipheral omlinganiselo wombane osebenzayo;Vavanya ixabiso lamandla ombane weDC kwiphini ngalinye le-IC ukuya emhlabeni, kwaye uthelekise nexabiso eliqhelekileyo, kwaye emva koko ucinezele uluhlu lwempazamo, ngaphandle kwezixhobo ezonakeleyo.
Xa uthatha imilinganiselo, nikela ingqalelo kwezi ngongoma zisibhozo zilandelayo:
①Iimitha ezininzi kufuneka zibe nokuchasana okwaneleyo kwangaphakathi, ngaphantsi kwamaxesha angama-10 ukuchasana kwesiphaluka esilinganisiweyo, ukuze kungabangela impazamo enkulu yokulinganisa.
② Ngokuqhelekileyo i-potentiometer kwindawo ephakathi, ukuba yi-TV, umthombo wesignali wokusebenzisa i-generator yesignali yebha yombala.
③bukela usiba okanye uvavanye ukuthatha amanyathelo achasene nokutyibilika.Ngenxa yokuba nayiphi na isiphaluka esifutshane ngokukhawuleza kulula ukuyonakalisa i-IC.Ezi ndlela zilandelayo zingathathwa ukuthintela ukutyibilika kwepeni: thatha ibhayisekile kunye nesiseko sevalve ebekwe kwi-table nib, kunye netafile ende yetafile malunga ne-05mm, enokwenza itafile nib inxibelelane kakuhle nendawo yovavanyo, kwaye iyakwazi ngokufanelekileyo ukuthintela ukutyibilika, nokuba ukubetha kwindawo ekufutshane akuyi kuba yisekethe emfutshane.
④Xa i-voltage ye-pin ingahambelani nexabiso eliqhelekileyo, kufuneka ihlalutywe ngokubhekiselele ekubeni i-voltage ye-pin inefuthe elibalulekileyo ekusebenzeni okuqhelekileyo kwe-IC kunye nokutshintsha okuhambelanayo kwamanye amandla ombane we-pin, ukuze kugwetywe umgangatho we-pin. NDIYABONA.
I-⑤IC pin voltage iya kuchaphazeleka ngamacandelo e-peripheral.Xa iinxalenye zeperipheral zenzeka ukuvuza, isiphaluka esifutshane, isekethe evulekileyo okanye ixabiso eliguquguqukayo, okanye i-peripheral circuit iqhagamshelwe kwi-potentiometer eguquguqukayo yokumelana, indawo yengalo yokutyibilika ye-potentiometer yahlukile, iya kwenza utshintsho lombane wepin.
⑥Ukuba i-IC pin voltage iqhelekile, i-IC ithathwa njengesiqhelo;Ukuba i-IC inxalenye yombane we-pin ayiqhelekanga, kufuneka iqale ukusuka kwinqanaba eliphezulu lokutenxa kwixabiso eliqhelekileyo, jonga i-peripheral components ayinayo impazamo, ukuba akukho mpazamo, i-IC inokuthi yonakaliswe.
⑦ Kwizixhobo zokwamkela eziguquguqukayo, ezifana nomabonwakude, xa kungekho mqondiso, i-IC pin voltage yahlukile.Ukuba kufunyaniswe ukuba i-pini yombane akufuneki itshintshe kodwa itshintshe enkulu, kunye nobungakanani bomqondiso kunye nezikhundla ezahlukeneyo zento enokuhlengahlengiswa kodwa ingatshintshi, umonakalo we-IC unokumiselwa.
⑧ Kwiindlela ezahlukeneyo zokusebenza zezixhobo, ezinje ngeerekhoda zevidiyo, kwiindlela ezahlukeneyo zokusebenza, i-IC pin voltage nayo yahlukile.

3. Indlela yokuvavanya amandla ombane we-Ac
I-AC voltage approximation ye-IC ilinganiswa nge-multimeter enefayile ye-dB.Ukuba akukho fayile ye-dB, inokufakwa emlonyeni phambi kwepeni.I-1-0.5 "ukwahlulwa komthamo we-DC. Le pateni isebenza kwabo banezakhelo zokusebenza ezisezantsi. Kodwa qaphela ukuba le miqondiso iya kuxhomekeka kwiifrikhwensi zendalo kwaye iya kwahluka ukusuka kwi-waveform ukuya kwi-waveform. .

4. Indlela yokulinganisa yangoku iyonke
Ngokulinganisa umbane opheleleyo we-IC, sinokugweba umgangatho we-IC.Ngenxa yobuninzi be-IC yangaphakathi yokudibanisa i-DC, umonakalo we-IC (ofana nokuphazamiseka kwe-PN junction okanye i-circuit evulekileyo) iya kubangela emva kwe-port inverted kunye ne-cut-off, ukwenzela ukuba utshintsho lulonke lwangoku.Ngoko ke ukulinganisa itotali yangoku kunokugweba umgangatho we-IC.Ixabiso langoku lingabalwa ngokulinganisa i-voltage ekuchaseni i-loop.
