12. Muaj kev paub txog
Lub hauv paus ntsiab lus ntawm kev kho cua kub SMD yog: siv cov cua kub zoo heev los sib sau ua ke ntawm cov pins thiab cov ntaub qhwv ntawm SMD kom yaj cov pob qij txha los yog rov ua cov khoom siv rov ua kom tiav qhov kev sib tsoo lossis vuam ua haujlwm. Lub tshuab nqus tsev twj tso kua mis nruab nrog lub caij nplooj ntoos hlav thiab cov roj hmab suction nozzle yog siv tib lub sij hawm rau disassembly. Thaum txhua qhov chaw vuam tau yaj, SMD cov cuab yeej tau maj mam nqus. Cov cua kub ntawm cov cua kub SMD kho qhov system tau paub los ntawm cov cua kub hloov pauv ntawm qhov sib txawv. Vim tias cov cua kub ntws tawm los ntawm qhov nruab nrab ntawm lub taub hau cua sov, nws yuav tsis ua rau SMD, lub substrate lossis cov khoom nyob ib puag ncig, thiab nws yooj yim rau disassemble lossis weld SMD.
Qhov sib txawv ntawm kev kho tshuab los ntawm cov tuam txhab sib txawv feem ntau yog vim muaj qhov sib txawv ntawm cov cua kub sib txawv los yog cov cua kub sib txawv. Qee lub nozzles ua rau cov cua kub nyob ib puag ncig thiab hauv qab ntawm SMD ntaus ntawv, thiab qee lub nozzles tsuas yog txau cov cua kub saum SMD. Los ntawm qhov pom ntawm cov khoom siv tiv thaiv, nws yog qhov zoo dua los xaiv airflow nyob ib puag ncig thiab hauv qab ntawm SMD li. Txhawm rau tiv thaiv PCB warpage, nws yog ib qho tsim nyog yuav tsum xaiv qhov kho qhov system nrog lub preheating muaj nuj nqi nyob rau hauv qab ntawm PCB.
Txij li thaum cov pob qij txha ntawm BGA tsis pom nyob rau hauv qab ntawm lub cuab yeej, cov txheej txheem rov ua haujlwm yuav tsum tau nruab nrog lub teeb pom kev sib cais (lossis hauv qab qhov kev xav kho qhov muag) thaum rov vuam BGA, txhawm rau xyuas kom meej qhov kev sib raug zoo thaum Mounting BGA.
13.2 BGA kho cov kauj ruam
Cov kauj ruam kho BGA yog qhov pib zoo ib yam li cov txheej txheem kho SMD ib txwm. Cov kauj ruam tshwj xeeb yog raws li nram no:
1. Tshem tawm BGA
muab lub phaj sib dhos rau saum npoo kom disassembled rau ntawm lub rooj ua haujlwm ntawm qhov system rework.
Muab lub phaj sib dhos rau saum npoo kom disassembled BGA rau ntawm lub rooj ua haujlwm ntawm qhov rov ua haujlwm.
xaiv lub square kub cua nozzle txuam qhov luaj li cas ntawm cov cuab yeej, thiab nruab lub cua kub nozzle ntawm lub connecting pas nrig.
lub cua sov sab sauv. Them mloog mus rau qhov ruaj khov installation
buckle cov cua kub nozzle ntawm lub cuab yeej, thiab xyuam xim rau qhov sib nrug deb ntawm lub cuab yeej. Yog tias muaj cov khoom nyob ib ncig ntawm lub cuab yeej uas cuam tshuam rau kev ua haujlwm ntawm lub tshuab cua kub, tshem cov khoom no ua ntej, thiab tom qab ntawd txuas lawv rov qab tom qab kho.
xaiv lub khob nqus dej (nozzle) haum rau cov cuab yeej yuav tsum tau disassembled, kho qhov siab ntawm lub tshuab nqus tsev nqus cov twj tso kua mis ntawm lub tshuab nqus tsev nqus tsev vacuum, txo qis saum npoo ntawm lub khob nqus mus cuag lub cuab yeej,
thiab qhib lub tshuab nqus tsev twj tso kua mis hloov
Thaum teem lub disassembly kub nkhaus, nws yuav tsum tau muab sau tseg tias qhov disassembly kub nkhaus yuav tsum
teem raws li cov kev mob tshwj xeeb xws li qhov loj ntawm cov cuab yeej thiab cov thickness ntawm PCB. Piv nrog
cov tsoos SMD, qhov disassembly kub ntawm BGA yog hais txog 150 degree siab dua.
tig lub zog cua sov thiab kho cov cua kub ntim.
Thaum lub solder melts tag, cov cuab yeej yog absorbed los ntawm lub tshuab nqus tsev pipette.
nqa cov cua kub nozzle, kaw lub tshuab nqus tsev twj tso kua mis, thiab ntes cov khoom disassembled.
2. Tshem tawm cov khoom seem ntawm lub PCB ncoo thiab ntxuav qhov chaw no
siv cov hlau soldering los ntxuav thiab theem cov seem seem ntawm PCB ncoo, thiab siv dismantling thiab vuam braid
thiab pav ca spade-zoo li tus soldering hlau taub hau rau tu. Ua tib zoo saib kom tsis txhob ua kom puas lub ncoo thiab lub ntsej muag lub ntsej muag thaum ua haujlwm.
ntxuav cov flux residue nrog cov tshuaj ntxuav xws li isopropanol lossis ethanol.
Kev kho dehumidification Vim tias PBGA rhiab heev rau cov dej noo, nws yog ib qho tsim nyog los xyuas seb lub cuab yeej puas yog
damped ua ntej sib dhos, thiab dehumidify lub damped ntaus ntawv.
(1) Txoj kev kho dehumidification thiab yuav tsum muaj:
Tom qab unpacking, xyuas cov av noo daim npav uas txuas rau lub pob. Thaum cov av noo qhia tau ntau tshaj 20% (nyeem thaum nws yog 23 degree ± 5 degree), nws qhia tau hais tias lub cuab yeej tau damped, thiab lub cuab yeej yuav tsum tau dehumidified ua ntej mounting. Lub dehumidification tuaj yeem nqa tawm hauv qhov cub hluav taws xob kom qhuav thiab ci rau 12-20h ntawm 125 ± degree.
(2) Kev ceev faj rau dehumidification:
(a) cov cuab yeej yuav tsum tau muab tso rau hauv qhov kub-resistant (ntau dua 150 degree) antistatic yas tais rau ci.
(b) lub qhov cub yuav tsum tau zoo-grounded, thiab dab teg ntawm tus neeg teb xov tooj yuav tsum tau nruab nrog ib tug anti-static bracelet nrog zoo grounding.
