Kusungirako ndi kugwiritsa ntchito zinthu zomwe zimakhudzidwa ndi kutentha ndi chinyezi

Electronic zigawo zikuluzikulu ndi zipangizo kwa chip processing, zigawo zina ndi osiyana osiyana, amafunika yosungirako wapadera kuonetsetsa kuti palibe mavuto, kutentha ndi chinyezi zigawo tcheru ndi mmodzi wa iwo.Kutentha ndi chinyezi tcheru zigawo kasamalidwe kusungirako mu ndondomeko processing ndi zofunika kwambiri, zidzakhudza kwambiri khalidwe la processing PCBA.Poonetsetsa smt SMD processing pamene ntchito yolondola kutentha ndi chinyezi zigawo tcheru, kuteteza zigawo zikuluzikulu ndi chilengedwe chinyezi, chinyezi ndi kugwiritsa ntchito odana malo amodzi ma CD zipangizo, mfundo zotsatirazi akhoza kukhala ogwira kasamalidwe kulamulira, kupewa kulamulira molakwika zinthu. ndi kukhudza khalidwe.

Njira zitatu zoyendetsera ntchito kuchokera ku zotsatirazi kuti mufufuze zotsatirazi

Kasamalidwe ka chilengedwe

Kasamalidwe ka ndondomeko

Kuzungulira kosungirako zigawo

I. Kasamalidwe ka chilengedwe (zigawo zosunga chinyezi zomwe zimakhudzidwa ndi chilengedwe)

General PCBA processing fakitale adzakhala dongosolo kulamulira kutentha ndi chinyezi zigawo zikuluzikulu tcheru, msonkhano malo kutentha ayenera kulamulidwa pa 18 ℃ -28 ℃.Posungira, kutentha kuyenera kuyendetsedwa pa 18 ℃-28 ℃ ndi chinyezi chachifupi chochepera 10%.Pofuna kusunga kutentha ndi chinyezi pamalo otsekedwa a fakitale, malowa asasiyidwe otsegula kapena otsegula kwa mphindi zopitirira zisanu.

Ogwira ntchito pazida maola 4 aliwonse kuti ayang'ane kutentha ndi chinyezi m'bokosi la bokosi, ndi kutentha kwake ndi chinyezi cholembetsedwa mu "tebulo lowongolera kutentha ndi chinyezi";ngati kutentha ndi chinyezi zimaposa zomwe zatchulidwa, dziwitsani ogwira nawo ntchito nthawi yomweyo kuti asinthe, potengera njira zoyenera zowongolera (monga kuyika desiccant, kusintha kutentha kwa chipinda kapena kuchotsa zigawo zomwe zili mubokosi lopanda chinyezi, kulowa mu chinyezi choyenera- bokosi la umboni)

II.Kasamalidwe ka ndondomekoyi (njira zosungirako zinthu zomwe zimakhudzidwa ndi chinyezi)

1. Pofuna kupewa kuwonongeka kwa zinthu zomwe zimayambitsidwa ndi magetsi osasunthika, pakuwonongeka kwa zinthu zomwe zimakhudzidwa ndi chinyezi, wogwiritsa ntchitoyo ayenera choyamba kuvala magolovesi abwino, mphete yapamanja yokhazikika, kenako ndikutsegula choyikapo pakompyuta yotetezedwa bwino. magetsi.Yang'anani ngati kutentha ndi kutentha kwa khadi kusintha kwa zigawozo kumakwaniritsa zofunikira, ndipo zigawo zomwe zimakwaniritsa zofunikira zikhoza kulembedwa.

2. Ngati mulandira zigawo zambiri zomwe zimakhudzidwa ndi chinyezi, khalani oyamba kutsimikizira ngati zigawozo ndizoyenera.

3. Onetsetsani kuti chikwama chopanda chinyezi chiyenera kutsagana ndi desiccant, khadi la chinyezi, ndi zina zotero.

4. Chinyezi tcheru zigawo (IC) pambuyo unpacking vakuyumu, kubwerera kwa solder pamaso pa kukhudzana nthawi mu mlengalenga sadzakhala upambana chinyezi tcheru zigawo zikuluzikulu kalasi ndi moyo, ayenera mosamalitsa malinga ndi lolingana miyezo ya PCBA processing chomera kuti. gwirani ntchito.

5. Kusungirako zinthu zosatsegulidwa ziyenera kusungidwa molingana ndi zofunikira, chifukwa zida zotsegulidwa ziyenera kuphikidwa ndikuyika m'matumba oteteza chinyezi ndi vacuum yosindikizidwa isanasungidwe.

6. Pazigawo zosayenerera, ziperekeni kwa ogwira ntchito yoyang'anira khalidwe kuti abwerere ku nyumba yosungiramo katundu.

III.Nthawi yosungira zigawo

Zosapitilira zaka 2 kuchokera tsiku lopangidwa ndi wopanga zida pazolinga zowerengera.

Pambuyo pogula, nthawi yowerengera ya wogwiritsa ntchito fakitale nthawi zambiri sichidutsa chaka chimodzi: Ngati chilengedwe chili ndi fakitale yachinyontho, pambuyo pogula zinthu zomwe zasonkhanitsidwa pamwamba, ziyenera kugwiritsidwa ntchito mkati mwa miyezi itatu, ndipo chinyezi choyenera - chiyenera kutengedwa. m'malo osungiramo zinthu komanso zoyikapo kuti zitsimikizire miyeso.
