Shenzhen Shinzo Technology Co., Ltd. yave kutenga batch nyowani yeIC chip yekuongorora michina, yekuyedza mifananidzo yemidziyo sezvakaratidzwa muchinyorwa chino, isu hatisi kungoda kuita basa rakanaka re-imwe-stop procurement services kune vatengi, asiwo ipai vatengi vedu kuona kuti machipi matsva uye epakutanga.Icho chinangwa chedu kushanda pamwe chete mukusimudzira kwenguva refu kwemakambani emumwe nemumwe!
IC Chip, Integrated Circuit Chip, ndeyekuisa nhamba huru yezvikamu zve-microelectronic (transistors, resistors, capacitors, etc.) yakagadzira dunhu rakasanganiswa pahwaro hwepurasitiki, kuitira kuti iite chip.
Parizvino, mhando yeIC chip inoita basa rakakura kwazvo mune zvese zvigadzirwa zvemagetsi, izvo zvinokanganisa zvakananga kunaka kwechigadzirwa chose mushure memusika.Saka kune vashandi vekutenga, maitiro ekuona nemazvo kunaka kweIC chip?Ichi chinyorwa chinosuma muchidimbu nzira dzakawanda.

1. Kuonekwa pasina Indaneti
Iyi nzira inoitwa kana IC isina kusungirirwa mukati medunhu.Muzhinji, multimeter inogona kushandiswa kuyera maitiro akanaka uye anodzokera kumashure ekudzivirira pakati pepini inoenderana nemapini epasi, uye IC mumamiriro ezvinhu akanaka ichafananidzwa.

2. Kuonekwa kwepaIndaneti
(1) DC kuramba kuona, zvakafanana nekuonekwa kwe-off-line
Uku ndiko kuona kwemamita akawanda eIC pini mudunhu (IC mudunhu) DC kuramba, AC uye DC voltage kusvika pasi uye iyo yakazara inoshanda ikozvino yekuona nzira.
(2) Kuyera kweDC kushanda voltage
Iyi inyaya yesimba, ine multi-metres DC voltage block DC supply voltage, peripheral zvikamu zvekushanda voltage kuyerwa;Edza kukosha kweDC voltage yepini yega yega IC pasi, uye uchienzaniswa neyakajairika kukosha, wobva wadzvanya iyo kukanganisa, kunze kwezvakakuvadzwa.
Pakuyera, teerera kune zvinotevera zvibodzwa zvisere:
①Iyo yakawanda-mamita inofanirwa kuve neyakakwana yemukati kuramba, isingasviki kagumi kupokana kweyeyero yedunhu, kuti isakonzeresa kuyerwa kukuru.
②Kazhinji iyo potentiometer kune yepakati chinzvimbo, kana iri TV, iyo chiratidzo sosi yekushandisa yakajairwa color bar sign jenareta.
③tarisa chinyoreso kana probe kutora anti-skid matanho.Nekuti chero ipapo pfupi dunhu riri nyore kukuvadza IC.Nzira dzinotevera dzinogona kutorwa kudzivirira kutsvedza kwepeni: tora bhasikoro nevhavha core yakaiswa patafura nib, uye refu tafura nib anenge 05mm, izvo zvinogona kuita kuti tafura nib zvakanaka kusangana pamwe bvunzo poindi, uye anogona zvinobudirira kudzivirira kutsvedza, kunyangwe ukarova nzvimbo yakatarisana haizopfupi dunhu.
④ Kana simba repini risingaenderane nehukoshi hwemazuva ese, hunofanirwa kuongororwa zvichienderana nekuti pini yepini ine simba rakakosha pane yakajairika mashandiro eIC uye shanduko dzinoenderana dzeimwe pini voltage, kuitira kutonga kunaka kwe. IC.
⑤IC pini voltage ichakanganiswa nezvikamu zvemukati.Kana izvo zvemukati zvikaitika kuvuza, kupfupika kwedunhu, kuvhurika dunhu kana kukosha kwakasiyana, kana dunhu redunhu rakabatana kune inosiyana inopikisa potentiometer, nzvimbo ye potentiometer inotsvedza ruoko yakasiyana, ichaita kuti pini voltage ichinje.
⑥Kana iyo IC pini voltage yakajairika, IC inowanzoonekwa seyakajairika;Kana iyo IC chikamu chepini yepini isina kujairika, inofanira kutanga kubva pakutsauka kwakanyanya kubva kune yakajairika kukosha, tarisa iyo peripheral zvikamu hazvina mhosva, kana pasina mhosva, IC inogona kukuvara.
⑦ Nezvemagetsi ekugamuchira michina, senge terevhizheni, kana pasina chiratidzo, iyo IC pin voltage yakasiyana.Kana zvikaonekwa kuti pini yepini haifanirwe kushanduka asi ichinje yakakura, iine saizi yechiratidzo uye nzvimbo dzakasiyana dzechinhu chinogadziriswa chinoshanduka asi chisingachinji, kukuvara kweIC kunogona kutsanangurwa.
⑧Kumhando dzakasiyana dzekushanda kwemidziyo, senge vhidhiyo rekodha, nenzira dzakasiyana dzekushanda, IC pini voltage zvakare yakasiyana.

3. Ac kushanda voltage test nzira
Iyo AC voltage approximation yeIC inoyerwa nemultimeter ine dB faira.Kana pasina dB faira, inogona kuiswa mumuromo pamberi pepeni.1-0.5 "kuparadzaniswa kweDC simba. Iyi pateni inoshanda kune avo vane yakaderera ma frequency ekushanda. Asi ziva kuti masaini aya achange ari pasi pemaitiro echisikigo uye achasiyana kubva waveform kuenda kune waveform. Saka iyo data yakayerwa ndeyekukosha kukosha, kungoreva chete. .

4. Yese ikozvino kuyerwa nzira
Nekuyera huwandu hwazvino hweIC simba rekupa, tinogona kutonga mhando yeIC.Nekuda kwehuwandu hweIC yemukati DC kubatanidza, IC kukuvadzwa (senge PN junction kuputsika kana kuvhurika redunhu) kunokonzeresa mushure meiyo inverted port uye kucheka-kubviswa, kuitira kuti iyo yakazara ikozvino shanduko.Saka kuyera huwandu hwazvino hunogona kutonga kunaka kweIC.Iko kukosha kwezvino kunogona kuverengerwa nekuyera voltage pakupokana kwechiuno.
