Kariya don Amfani da Abubuwan SMT

Yanayin muhalli don adana abubuwan haɗin saman ƙasa:
1. Na yanayi zazzabi: ajiya zazzabi <40 ℃
2. Zazzabi na wurin samarwa <30 ℃
3. Yanayin zafi: <RH60%
4. Yanayi na muhalli: ba a ba da izinin iskar gas mai guba irin su sulfur, chlorine da acid wanda ke shafar aikin walda a cikin wurin ajiya da aiki.
5. Matakan Antistatic: saduwa da buƙatun antistatic na abubuwan SMT.
6. Lokacin ajiya na abubuwan da aka gyara: lokacin ajiya bazai wuce shekaru 2 daga ranar samar da kayan aikin ba;Lokacin lissafin na masu amfani da masana'antar injin bayan siyan gabaɗaya bai wuce shekara 1 ba;Idan masana'anta tana cikin yanayin yanayi mai ɗanɗano, yakamata a yi amfani da abubuwan SMT a cikin watanni 3 bayan siyan, kuma yakamata a ɗauki matakan tabbatar da danshi masu dacewa a cikin wurin ajiya da marufi na abubuwan.
7. Na'urorin SMD tare da buƙatun juriya na danshi.Dole ne a yi amfani da shi a cikin sa'o'i 72 bayan buɗewa kuma bai wuce mako ɗaya ba.Idan ba za a iya amfani da shi ba, ya kamata a adana shi a cikin akwatin bushewa na RH20%, kuma na'urorin SMD da suka bushe ya kamata a bushe su bushe kamar yadda aka tanadar.
8. The SMD (SOP, Sj, lCC da QFP, da dai sauransu) cushe a cikin roba tube ba high zafin jiki resistant kuma ba za a iya kai tsaye gasa a cikin tanda.A sanya shi a cikin bututun ƙarfe ko tiren ƙarfe don toya.
9. QFP marufi farantin filastik ba babban zafin jiki ba ne kuma tsayin daka mai tsayi biyu.High zafin jiki resistant (bayanin kula Tmax = 135 ℃, 150 ℃ ko MAX180 ℃, da dai sauransu) za a iya kai tsaye sa a cikin tanda don yin burodi;Ba babban zafin jiki ba zai iya zama kai tsaye a cikin yin burodin tanda, idan akwai haɗari, ya kamata a sanya shi a cikin farantin karfe don yin burodi.Ya kamata a hana lalacewa ga fil yayin juyawa, don kada ya lalata kaddarorin su na coplanar.
Sufuri, rarrabuwa, dubawa ko hawa da hannu:

Idan kana buƙatar ɗaukar na'urar SMD, sa madaidaicin wuyan hannu na ESD kuma yi amfani da tsotsan alƙalami don guje wa lalata fil ɗin na'urorin SOP da QFP don hana faɗar fil da lalacewa.
Za a iya ajiye ragowar SMD kamar haka:

An sanye shi da ƙananan zafin jiki na musamman da akwatin ajiya mai ƙarancin zafi.Ajiye SMD wanda ba a amfani da shi na ɗan lokaci bayan buɗewa ko tare da mai ciyarwa a cikin akwatin.Amma sanye take da manyan ƙananan zafin jiki na musamman da ƙarancin zafi na ajiyar tanki ya fi girma.

Yi amfani da jakunkuna na marufi na asali.Muddin jakar ta kasance cikakke kuma mai desiccant yana cikin yanayi mai kyau (duk da'irar baƙar fata akan katin nuna zafi shuɗi ne, babu ruwan hoda), SMD ɗin da ba a yi amfani da shi ba har yanzu ana iya mayar da shi cikin jakar kuma a rufe shi da tef.
