Cov lus qhia no yuav siv cov txheej txheem txheej txheem txheej txheem los qhia koj yuav ua li cas rov thim yas BGA li ntawm 10 feeb lossis tsawg dua. Koj yuav xav tau:
1. Reflow qhov chaw (reflow qhov cub, cua kub system, IR system)
2. Muab tshuaj txhuam (dej zoo dua yog qhov zoo dua)
3. Soldering hlau w/hniav taub
4. Khaub ncaws/Khaub ncaws
5. Kim so
6. Dej thiab txhuam txhuam kom huv
7. Tshawb xyuas qhov chaw
8. Qhov tseeb preform raws li cov ntaub ntawv siv tshuab ntawm ib feem tau rov ua dua
9. Ntaus ntawv kom rov ntaus dua
10. ESD dab teg
Kauj Ruam 1: Tshem tawm lub Device
Thov siv cov dej sib tov sib xyaw flux siv lub koob txhaj tshuaj thiab pleev nrog cov ntiv tes gloved ntawm cov khoom ntawm lub cuab yeej. Siv cov hniav zoo thiab qhov ntsuas kub raws qhov sib xyaw ntawm cov khoom sib dhos, tshem cov khoom sib dhos. Siv cov hlua txhuam kom tshem cov laug uas seem kom paub tseeb tias cov ntaub qhwv tau tiaj tus.
Kauj Ruam 2: Ntxuav Qhov Deballed Part
Siv cov cawv isopropyl thiab cov ntaub so tsis zoo li qub so so cov dej ntws los ntawm hauv qab ntawm qhov deballed.
Kauj Ruam 3: Thov Muab Tshuaj Txhuam
Txheeb xyuas lub cuab yeej kom paub tseeb tias tsis muaj daim npog ntsej muag tsis tau rub cov ntaub qhwv hauv qab ntawm lub cuab yeej. Thov siv cov dej sib tov muab tshuaj txhuam tso rau hauv qab ntawm ib feem. Tshaj nrog txhuam txhuam kom txog thaum tuab tuab nyob hauv qab ntawm ib feem.
Kauj Ruam 4: Muab Preform Pob Sab Rau
Muab lub pob preform ib sab nce mus rau lub tshav kub uas tiv taus cua sov zoo li lub phaj tiaj tiaj. Xyuas kom tseeb tias cov kab preform nce mus txog cov qauv ntawm lub cuab yeej. Nco ntsoov tias koj tau txuas cov khoom sib txuas kom raug kom haum rau cov khoom sib dhos.
Kauj Ruam 5: Ua tib zoo tso lub cuab yeej rau saum Preform
Ua tib zoo muab lub cuab yeej tso rau sab saum toj ntawm BGA reballing preform kom ntseeg tau tias cov qauv kev coj ua raug.
Kauj Ruam 6: Square Up Preform rau Ntaus Ntawv
Siv lub kaum sab xis lossis lwm qhov ntsuas "square up" preform rau BGA.
Kauj Ruam 7: Rov ua dua
Qhov chaw "qhaub cij" kev tsim ua ntej ntawm cov khoom siv thiab khoom siv rau hauv qhov cub kom sov lossis lwm qhov chaw sov. Xyuas kom tseeb tias qhov ntsuas kub kom raug nyob hauv qhov chaw.
Kauj Ruam 8: Tshem Preform
Thaum tseem sov me ntsis tshem qhov preform los ntawm lub cuab yeej. Txheeb xyuas kom paub tseeb tias txhua lub pob tau pauv mus rau lub cuab yeej. Ntxuav nrog dej thiab txhuam mos. Rov tshuaj xyuas qhov khawb ntawm daim npog ntsej muag lossis nqa cov pawm.
Kauj Ruam 9: Tshawb xyuas Reballed Device
Txheeb xyuas cov cuab yeej rov ua dua tshiab raws li qhov loj me rau cov qauv uas koj xav hauv siab. Yog tias koj xav kom muaj ib tus neeg ua qhov kev pabcuam ntaus pob rov qab ces hu rau BEST Inc.
