11. Cov kev paub zoo rau BGA rework reballing chaw nres tsheb

 

Cov kauj ruam siv BGA rework chaw nres tsheb

1. Pib tus txheej txheem:

1.1 Txheeb xyuas tias kev sib txuas ntawm cov khoom siv hluav taws xob sab nraud yog 220V.

1.2 Qhib lub hwj chim hloov ntawm txhua chav tsev ntawm lub tshuab

3. Cov txheej txheem disassembly:

3.1 Daim npav PCBA BGA yuav raug muab tshem tawm yog tsau rau hauv kev txhawb nqa ntawm daim npav PCBA.

3.2 Txav mus rau PCBA mus rau qhov siab txwv bar, kho qhov siab ntawm kev txhawb nqa ncej kom sab saum toj ntawm PCBA nyob rau hauv kev sib cuag.

nrog rau hauv qab ntawm qhov siab txwv bar.

3.3 Tig lub taub hau ntawm lub moos mus rau 90 degree txoj hauj lwm ncaj qha rau pem hauv ntej thiab txav PCBA mus rau nruab nrab ntawm txoj hauj lwm ntawm lub com-

ponent yuav tsum tau muab tshem tawm thiab qhov chaw liab ntawm lub taub hau kev sib raug zoo.

3.4 Siv tus kov los xaiv qhov kev pab cuam cua sov kom tshem tawm cov khoom

3.5 Tso lub taub hau rau sab laug cua sov ncaj qha rau ntawm cov khoom kom raug tshem tawm thiab lub tshuab yuav cia li ua kom sov cov khoom.

3.6 Yog rhuab mus rau 190 degrees, lub tshuab emits ib intermittent "beep ... beep" suab. Lub sijhawm no, qhov kub thiab txias yog calibrated o-

nce (control button); Thaum lub tshuab ua kom sov kom emit ib "beep ... nruam beep", lub tshuab nqus tsev hloov yog nyob rau, nias kom nqa lub taub hau,

nqus cov tivthaiv, tig lub taub hau cua sov ntawm sab laug platform ntawm cov khoom tivthaiv, nias kom tsa koj lub taub hau, BGA yuav

poob cia li thiab BGA yuav raug tshem tawm.

3.7 Ua raws li cov kauj ruam saum toj no kom tshem tawm cov khoom.

4. Cov txheej txheem ntawm kev thauj khoom cov khoom:

4.1 Lub PCBA tau thauj khoom raws li cov kauj ruam tau piav qhia hauv cov ntsiab lus 3.1-3.2 saum toj no.

4.2 Teem lub BGA yuav tsum tau soldered nyob rau hauv nruab nrab ntawm lub platform uas lub BGA txuas nrog, txav lub PCB bracket (sab laug-txoj cai dire-

ction) kom BGA ncaj qha nyob rau hauv lub tshuab nqus tsev nozzle. Nias lub khawm, qhov qis ntawm lub teeb lub taub hau mus rau hauv qab kawg,

manually tig qhov hloov ntawm lub taub hau teeb kom paub tseeb tias lub nozzle nce mus txog saum npoo ntawm BGA thiab ua rau lub cuab yeej a-

utomatically tig ntawm lub tshuab nqus tsev hloov (lub tshuab nqus tsev vacuum), ces manually tig nws mus rau qhov qub, nias lub khawm kov thiab

lub taub hau positioning cia li nce mus rau qhov chaw siab tshaj.

4.3 Tshem tawm cov cuab yeej kaw kom nws ncaj qha nyob rau hauv lub nozzle tivthaiv, txav lub PCB board tuav kom txoj hauj lwm ntawm

cov tivthaiv yuav tsum tau soldered yog ncaj qha nyob rau hauv cov ntaubntawv povthawj siv cuab yeej thiab kho qhov siab ntawm cov khoom tsim nyog los tsim

daim duab meej

4.4 Koj tuaj yeem pom tias lub monitor muaj liab BGA pins thiab xiav PAD ncoo cov ntsiab lus. Kho ob txoj hlua khi rau lawv qhov sib xws

ua haujlwm ib zaug. Tom qab muab tso rau hauv nruab nrab, thawb lub locator mus rau qhov chaw qub thiab nias lub khawm kov kom tawm ntawm BGA co-

mponent mounts nyob rau hauv txoj hauj lwm ntawm cov khoom sib txuas ntawm PCB board kom txog thaum lub tshuab nqus tsev hloov lub teeb (lub tshuab nqus tsev vacuum)

tawm mus, nqa me ntsis lub taub hau mounting thiab nias lub pob kom rov qab mus rau lub taub hau mounting.

4.5 Rov ua dua cov kauj ruam 3.3-3.5 saum toj no

4.6 Yog tias cua sov rau 190 degrees, lub tshuab emits ib "beep ... beep". Saib cov txheej txheem soldering nyob rau hauv qab ntawm cov khoom

los ntawm kev saib), qhia tias cov khoom siv tau ua tiav ib txwm, tshem lub taub hau cua sov thiab txav lub PCBA mus rau

kiv cua kom txias.

 

5. Kev ntsuas kub:

Stripping kub qhov chaw:

Saib cov configuration muab nrog lub tshuab

Welding kub hloov:

Saib cov configuration muab nrog lub tshuab

 

6. Cov teeb meem xav tau kev saib xyuas:

1. Ua tib zoo saib xyuas kev sib cuag ntawm txhua lub cuab yeej siv thaum lub sijhawm ua haujlwm kom tsis txhob muaj kev puas tsuaj rau cov khoom muaj feem xyuam.

2. Tus neeg teb xov tooj saib xyuas nws tus kheej kev nyab xeeb kom tsis txhob muaj hluav taws xob poob siab thiab kub hnyiab.

3. Khaws thiab tswj cov khoom siv, ua kom txhua yam huv si thiab huv si.

4. Tom qab siv cov khoom siv, nws yuav tsum tau teeb tsa raws sijhawm, ua kom zoo thiab ua raws li 5S cov cai.

5. Yog tias muaj teeb meem tshwm sim, daws tam sim ntawd los ntawm tus kws tshaj lij lossis cov txheej txheem engineer.
