Aikace-aikace na madaidaicin mitar tushe a cikin gwajin samar da taro na diode

Diode na'urar lantarki ce da aka yi da kayan semiconductor (silicon, selenium, germanium, da sauransu). Yana da ɗawainiya ta unidirectional, wato, lokacin da aka yi amfani da wutar lantarki na gaba akan anode na diode, diode yana kunna. Lokacin da aka yi amfani da wutar lantarki na baya ga anode da cathode, diode yana kashe. Ana amfani da diodes sosai. Musamman, a cikin da'irori daban-daban na lantarki, diodes suna da alaƙa da haɗin gwiwa tare da abubuwan haɗin gwiwa kamar resistors, capacitors, da inductor don samar da da'irori tare da ayyuka daban-daban, waɗanda zasu iya aiwatar da ayyuka da yawa kamar gyaran AC, gano siginar da aka daidaita, iyakance girman girman da clamping. da ƙarfin ƙarfin lantarki na ƙarfin wutar lantarki. Ko a cikin da'irori na rediyo gama gari ko a cikin wasu kayan aikin gida ko da'irori masu sarrafa masana'antu, ana iya samun alamun diodes.

Akwai babban bambanci tsakanin gwajin samar da batch na diodes da gwajin diodes a ƙarƙashin yanayin dakin gwaje-gwaje. Na farko, girman batch na gwajin masana'antu yana da girma, kuma kayan aikin gwaji yana gwada dubun-dubatar diodes akan matsakaita kowace rana. Farashin fakitin diodes a kasuwannin duniya gabaɗaya ya fi rahusa, kuma manyan kayayyaki ne kawai za su iya samun riba mai yawa don sa masana'antun su sami riba. Sabili da haka, ana buƙatar kayan aiki don cimma ci gaba da gwaji mai sauri. Abu na biyu, ana buƙatar kayan gwajin don samun ɗan ƙima na ƙima, samun damar gwada nau'ikan diodes daban-daban, da kuma iya canza nau'in a kowane lokaci. Na uku, ana buƙatar yin amfani da ƙarfin lantarki ko halin yanzu daidai gwargwadon yanayin gwaji don tabbatar da takamaiman gwajin gwaji. Sabili da haka, tsarin gwaji don fakitin diodes wani tsarin haɗaka ne mai cikakken atomatik, wanda zai iya kammala jerin ayyuka daga ciyarwa, tsarawa, gwaji, siliki-tallafi zuwa tattara diodes. Ba a buƙatar sa hannun hannu yayin duk gwajin.

Tsarin gwajin diode ya ƙunshi sassa biyu. Ɗayan sashi shine na'ura mai sarrafawa (manipulator, fixture, conveyor, da dai sauransu), wanda yafi sarrafa dukkan tsarin diodes daga ciyarwa zuwa shiryawa. Sauran bangaren kuma shine NGI high-precision digital source meter, wanda ake amfani dashi don saita yanayin gwaji don gwada manyan sigogin diode kamar wutar lantarki ta kan-jihar (VF), reverse breakdown voltage (VR) da leakage current ( IR), kuma yana da ayyuka kamar tantancewa da tsarawa.
