Kugwiritsa ntchito mita yolondola kwambiri pakuyesa kupanga misa kwa diode

Diode ndi chipangizo chamagetsi chopangidwa ndi zida za semiconductor (silicon, selenium, germanium, etc.). Ili ndi conductivity ya unidirectional, ndiye kuti, pamene magetsi akutsogolo akugwiritsidwa ntchito ku anode ya diode, diode imatsegulidwa. Pamene voteji yowonongeka ikugwiritsidwa ntchito ku anode ndi cathode, diode imazimitsidwa. Ma diode amagwiritsidwa ntchito kwambiri. Makamaka, m'mabwalo osiyanasiyana amagetsi, ma diode amalumikizidwa bwino ndi zinthu monga resistors, capacitors, ndi inductors kuti apange mabwalo okhala ndi ntchito zosiyanasiyana, zomwe zimatha kuzindikira ntchito zingapo monga kukonzanso kwa AC, kuzindikira ma siginecha osinthika, kuchepetsa matalikidwe ndi kuwongolera, ndi kukhazikika kwamagetsi kwamagetsi amagetsi. Kaya mumawayilesi wamba kapena pazida zina zapakhomo kapena makina owongolera mafakitale, ma diode amatha kupezeka.

Pali kusiyana kwakukulu pakati pa kuyesa kwa ma diode ndi kuyesa kwa ma diode pansi pamikhalidwe ya labotale. Choyamba, kukula kwa batchi yoyesera mafakitale ndi yayikulu, ndipo chida choyesera chimayesa ma diode masauzande pafupifupi tsiku lililonse. Mtengo wa ma diode opakidwa pamsika wapadziko lonse lapansi nthawi zambiri umakhala wotsika mtengo, ndipo kupanga kwakukulu kokha komwe kumatha kupangitsa kuti opanga apindule. Choncho, chidacho chimayenera kukwaniritsa kuyesa kosalekeza komanso mofulumira. Kachiwiri, chida choyesera chimafunika kuti chikhale ndi kuchuluka kwa zinthu zosiyanasiyana, kuyesa mitundu yosiyanasiyana ya ma diode opakidwa, ndikutha kusintha mtunduwo nthawi iliyonse. Chachitatu, pamafunika kugwiritsa ntchito mphamvu yamagetsi kapena yapano motsatira miyeso yoyeserera kuti muwonetsetse kuti mayesowo ali olondola. Chifukwa chake, njira yoyesera ya ma diode opakidwa ndi njira yophatikizika yodziwikiratu, yomwe imatha kumaliza ntchito zingapo kuyambira pakudyetsa, kukonza, kuyesa, kuyesa silika mpaka kulongedza ma diode. Palibe kulowererapo pamanja komwe kumafunikira panthawi yonse yoyezetsa.

Dongosolo loyeserera la diode lili ndi magawo awiri. Gawo limodzi ndi makina owongolera (manipulator, fixture, conveyor, etc.), omwe amawongolera kwambiri njira yonse ya ma diode kuyambira pakudyetsa mpaka kulongedza. Gawo lina ndi NGI high-precision digital source mita, yomwe imagwiritsidwa ntchito kuyika miyeso kuyesa magawo akulu a diode monga voltage ya on-state (VF), reverse breakdown voltage (VR) ndi leakage current ( IR), komanso ili ndi ntchito monga kuwunika ndi kukonza.

NGI N2600 mndandanda wa mita yolondola kwambiri ya digito imagwira ntchito m'magawo anayi, kuphatikiza ntchito zisanu ndi imodzi za gwero lamagetsi, gwero lapano, mita yama digito (miyeso ya I/V/R), ndi katundu. Muyezo wosiyanasiyana umakwirira 200V mpaka 1μV, 1A mpaka 10pA, 200MΩ mpaka 10μΩ, ndipo kusamvana kwa muyeso kumafikira manambala 6.5. Ili ndi mawonekedwe ojambulira, digito IO, kuyesa malire, choyambitsa cholumikizira, jenereta yolumikizira, chowerengera chantchito ndi ntchito zina, ndipo imapereka pulogalamu yaulere yowongolera ma PC, yomwe ili yoyenera kwambiri pakuyesa kwa batch kupanga ma diode opakidwa.

N2600 mndandanda wolondola kwambiri wa mita ya digito uli ndi madoko 10 a digito IO. Chizindikiro cha digito cha IO chitha kugwiritsidwa ntchito kulumikizana ndi chowongolera kuti chiwongolere chowongolera kuti achite mayeso a polarity ndikuwunika kalasi pa diode. Ma diode amatha kugawidwa m'magulu azinthu zowonongeka pogwiritsa ntchito kuyesa kwa magetsi, omwe nthawi zambiri amagawidwa m'magulu anayi: AAA, AA, A, ndi D. Zowonongekazo zimachotsedwa ndi kuwunika kwamagulu, ndipo wopanga akhoza kutumiza malinga ndi zosowa za makasitomala. Chizindikiro chotuluka pa doko lililonse la digito la IO la mita yoyambira chimayimira mtundu wa chidziwitso, monga "chipangizo chabwino", "chipangizo chowonongeka", "chipangizo chozungulira", ndi zina. Phukusi la diode kapena diode limayikidwa muzoyeserera ndikulumikizidwa. ku gwero la mita. Kutengera phukusi la diode, ma diode ena amakhala ndi zithunzi. Pofuna kupewa mafunde owopsa, chipinda choyesera chomwe chimatha kuteteza diode ku kuwala chimagwiritsidwa ntchito nthawi zambiri. Meta yoyambira imapereka kukondera kwamagetsi kapena kukondera kwapano ku diode ndikumaliza muyeso, kufananiza zotsatira zake ndi mtengo woikidwiratu kwambiri ndikupanga chigamulo kapena kulephera.

● Njira yoyeserera yoyambitsira yolumikizana ya ma gwero angapo a mita

1.Wogwiritsa ntchito amatumiza malangizo ogwiritsira ntchito kudzera pa kompyuta yolandirayo podina batani la "Start Test", kudikirira conveyor ndi loboti ndi fixture kudyetsa batch yopanga diode.
2.Kompyuta yochititsa chidwi imatumiza malangizo kudzera pa LAN kuti ayang'ane mita ya N2600 kuti ayambe kugwira ntchito.
3.The source mita N2600 amadikirira kuyesa koyambira (SOT) choyambitsa chizindikiro kuchokera ku robot.
4.Roboti imatumiza chizindikiro choyambitsa SOT ku mita yoyambira N2600, kusonyeza kuti ma diode onse ali okonzeka kuyesa synchronous.
5.Multiple source meters N2600 amayambika mogwirizana kuti ayese polarity. Ngati mayeso a diode polarity ali abwino, ndiye kuti ma gwero angapo a mita N2600 pitilizani kuyesa magwiridwe antchito (gawo 6). Ngati mayeso a diode polarity asintha, ndiye tumizani chizindikiro cha digito cha IO ku loboti kuti mutembenuze chipangizocho ndikubwerera ku sitepe 4. (Pamene mayeso a polarity abwerera kumbuyo, chipangizochi chimathanso kuzunguliridwa popanda kuzungulira. Popeza mita yoyambira N2600 imagwira ntchito. mu ma quadrants anayi, ma voliyumu ndi njira zomwe zimachokera pano zimatha kuwongoleredwa ndi mapulogalamu kuti akwaniritse mayesowo, kupulumutsa nthawi yogwiritsira ntchito loboti yozungulira chipangizocho)
6.Pamene polarity ya diode ili yabwino, gwero la mita N2600 limapanga kuyesa kwa diode mu dongosolo lomwe likuwonetsedwa ndi pulogalamu yoyendetsa mayeso, imapanga chiweruzo choyenera ndikusunga deta ya mayesero aliwonse.
7.The source mita N2600 imatumiza chizindikiro cha digito cha IO ku robot kuti ipange ndi kusanja, ndikutumiza chizindikiro cha mapeto a mayeso (EOT) ku robot kuti igwire ntchito ya nkhonya, ndikusunga deta yazinthu zamtundu uliwonse.
8.Dikirani gulu lotsatira la mayeso odyetsa diode ndikubwereza masitepe omwe ali pamwambapa.
