    Na'urar gani /Tsarin Marufi Na Na'urar gani Ba ku sani ba-SMD

    Lokacin aikawa: Dec-06-2019

    Mataki na farko a cikin tsarin karɓar guntu na iya zama facin; a TO ya haɗa da facin da zafi ke nutsewa zuwa soket ɗin TO, guntu wanda ke LDs zuwa magudanar zafi, da kuma PD na baya;

    Ƙayyadadden tsari na hawan hawan yana iya bambanta sosai: abin da za a haɗa shi yawanci guntu LD / PD, ko TIA, resistor / capacitor; za a iya yi da jeri a kan aluminum nitride zafi kwatami ko kai tsaye a kan PCB; da jeri Eutectic waldi ko conductive m za a iya amfani da; facin na iya buƙatar dubun ko ma ɗaruruwan microns na daidaito kawai, kamar TIA, resistors, da daidaiton ƙananan micron, kamar walda mai juzu'i.

    Bayan an faɗi wannan duka, menene ainihin faci? Ba a taɓa samun daidaitaccen ma'anar ba. Koyaya, ana iya gani daga misalan da ke sama cewa suna da abu ɗaya gama gari: ana amfani da na'urar don sanyawa da gyara jikin jeri akan mai ɗaukar hoto tare da takamaiman daidaito don cimma takamaiman aiki. (Me yasa ake amfani da kayan aiki? Ina tsammanin tsarin sanyawa wanda za'a iya sarrafa shi ana kiransa patch, in ba haka ba za'a iya kiransa haɗin gwiwar hannu kawai.) Dangane da wannan batu na yau da kullum, na taƙaita mahimman abubuwa guda huɗu na facin: jikin sanyawa, mai ɗaukar kaya , Kafaffen Hanyar, daidaito. Kuma abin da aka yi amfani da shi, abin da aka zaɓa, da kuma abin da ake bukata na daidaito, ya dogara ne gaba ɗaya ga aikin da abin da za a saka yake bukata don cimma.

    Anan ne kalli dama daban-daban da ke ƙunshe cikin abubuwa huɗu na facin:

    Yawancin abubuwan hawa sune LD da PD kwakwalwan kwamfuta.

    TIA / Direba / Resistor / Capacitors, kamar jikunan sanyawa waɗanda ba sa buƙatar babban daidaito, ana iya maye gurbinsu da hannu maimakon manyan kundin.

    Mafi na al'ada dillali ne AIN zafi nutse; tare da haɓaka kwakwalwan kwamfuta masu haɗaka, kwakwalwan kwamfuta na PLC da kwakwalwan kwamfuta na siliki suma sun zama jikin masu hawa na yau da kullun, irin su silicon light grating coupling chips, waɗanda ke buƙatar saka LaMP akan kwakwalwan gani na silicon; PCB shine masu dako na gama gari a cikin fakitin COB, kamar sadarwar bayanai 100G-SR4 modules, PD/VSCEL ana hawa kai tsaye akan PCB.

    Au80Sn20 alloy shine na kowa LD-Mount eutectic solder. Ana amfani da mannen ɗabi'a sau da yawa don hawan PD. Ruwan tabarau mai manne UV ya fi dacewa.

    Daidaito ya dogara da takamaiman aikace-aikace;

    Inda ake buƙatar haɗakar hanyar gani, daidaitattun buƙatun yana da girma.

    Daidaitawa mai wucewa yana buƙatar daidaito mafi girma fiye da haɗakarwa mai aiki.

    Sanya LD yana buƙatar daidaito mafi girma fiye da jeri na PD,

    TIA / resistor / capacitor baya buƙatar kowane daidaici, kawai tsaya shi.

    Inda daidaito bai yi girma ba, kawai kuna buƙatar duba ƙasa a CCD don ɗaukar hotunan guntu da ma'auni a lokaci guda, kuma amfani da alamun jeri ko gefuna guntu don daidaitawa.

    010

    Don aikace-aikacen juye-chip, ana kuma buƙatar CCDs da yawa, suna duban ƙasan guntu da saman ma'aunin. Aikace-aikace masu inganci kuma suna buƙatar alamun jeri na musamman.
