Tsis siv neeg BGA rework tshuab siv rau tsheb ECU kho
Tshiab tsim tsis siv neeg rework chaw nres tsheb DH-A2E yog lub tshuab high-end uas feem ntau yog siv rau kev kho chip-theem, tsis hais lub tsheb lossis tsheb ECU, ob leeg tuaj yeem kho los ntawm nws.
Kev khiav hauj lwm lub tshuab yog yooj yim heev, vim hais tias nws yog siab automtic nrog pom mounting txheej txheem, nws
kub profiles tuaj yeem tsim ua ntej thiab txuag rau kev siv dua lwm zaus, koj tsuas yog yuav tsum nyem "xaiv" qhov twg koj tuaj yeem xaiv ib qho ntawm cov profile koj xav tau rau desoldering lossis soldering.

Kev paub ntau ntxiv txog ECU:
Feem ntau, tsheb nruab nrog microprocessor tswj units muaj qhov ua txhaum kev kuaj tus kheej. Nws tuaj yeem siv los txiav txim siab thiab saib xyuas cov xwm txheej ua haujlwm ntawm kev sib kis thiab kev tswj hwm hauv lub tsheb. Thaum lub tsheb tawg lawm, lub teeb pom kev tsis raug teeb tsa ntawm lub dashboard yuav flash ceeb toom tus tswv tias lub tsheb yuav muaj teeb meem. Thaum lub laub ntawm ib lub pob, qhov txhaum cai raug tso tawm ntawm lub dashboard. Nyob rau tib lub sijhawm, qhov teeb meem txhaum cai yuav raug muab khaws cia rau hauv lub cim xeeb, txawm tias qhov hluav taws xob hloov hluav taws xob raug txiav, qhov txhaum raug tshem tawm, thiab lub teeb pom kev txhaum raug kaw, qhov teeb meem txhaum cai tseem yuav khaws cia hauv lub cim xeeb rau cov neeg ua haujlwm tu. txiav txim qhov txhaum ntawm lub tsheb. Tom qab kev daws teeb meem, txiav tawm lub zog ntawm ECU rau 30 vib nas this thiab DTC yuav raug tshem tawm. Qhov kev kuaj mob nws tus kheej tsis raug cai saib xyuas kev ua haujlwm ntawm lub tsheb txhua lub sijhawm. Txawm hais tias lub hau me me yog xoob, nws yuav raug cuam tshuam los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau lub sijhawm thiab xyuas kom muaj kev nyab xeeb ntawm lub tsheb. Tshwj xeeb, qib ntawm cov khoom siv hluav taws xob hauv cov tsheb niaj hnub niaj hnub tau txhim kho tas li, uas ua kom zoo rau kev ua haujlwm ntawm lub tsheb, tab sis kuj ua rau cov kev tswj hwm ntawm lub tsheb ntau thiab ntau txoj hauv kev. Thaum cov khoom siv hluav taws xob tsis zoo no ua tsis tiav, nws yuav ua rau muaj kev cuam tshuam loj heev. Txhawm rau txhawm rau kuaj xyuas qhov chaw ua txhaum sai thiab txhim kho kev ua haujlwm ntawm kev saib xyuas, lub ntiaj teb cov tuam txhab tsheb loj tau tsim kho nws tus kheej qhov kev kuaj xyuas tus kheej.
Yog tias qhov txhaum tsis tuaj yeem raug tshem tawm thiab ECU yuav tsum tau kho, tshwj xeeb tshaj yog, qee qhov chips ntawm lawv yuav tsum tau
rework, tsis siv neeg BGA rework tshuab yog ib yam khoom tsim nyog, ntawm no yog ib tug yees duab rau koj siv:
Lub tsheb ntes tshwj xeeb
Nyob rau xyoo 1970s, txhawm rau txhim kho kev yooj yim ntawm kev siv thiab kev saib xyuas ntawm cov tsheb niaj hnub no, cov cuab yeej tshwj xeeb ntawm lub tsheb tau tshwm sim los kuaj xyuas cov kev ua haujlwm ntawm lub tsheb hluav taws xob tswj tshuab. Piv txwv li, EEC-I thiab EEC-II detectors tsim los ntawm Ford Tuam Txhab hauv Tebchaws Meskas tuaj yeem siv los saib xyuas cov teeb liab ntawm lub tshuab hluav taws xob tswj hluav taws xob thiab tshawb xyuas qhov chaw txhaum. Vim yog cov kev cai siab tshaj plaws rau cov neeg ua haujlwm thaum kuaj xyuas qhov tsis raug, cov cuab yeej tshwj xeeb no tsis tau nrov.
On-board diagnostic system
Nyob rau xyoo 1980s, ib hom kev kuaj mob tshiab, cov txheej txheem kuaj mob hauv lub nkoj tau tawm los. Nws siv lub microprocessor tswj chav kuaj xyuas thiab kuaj xyuas cov khoom ntawm lub tshuab hluav taws xob tswj thiab nrhiav kev ua txhaum ntawm nws tus kheej, yog li nws tseem hu ua qhov txhaum tus kheej kev kuaj mob. Vim tias nws tuaj yeem saib xyuas qhov tsis tu ncua ntawm lub tsheb hluav taws xob tswj qhov system thiab kaw qhov tsis sib xws ntawm cov txheej txheem thaub qab, nws yooj yim los nrhiav qhov yuam kev hauv lub sijhawm, yog li nws tau siv dav. Txawm li cas los xij, vim qhov tsawg ntawm lub cim xeeb ntawm microprocessor, nws cov khoom kuaj tau raug txwv rau qee qhov, thiab ntau qhov kev ua txhaum tsis tuaj yeem kuaj pom, yog li tib neeg tab tom txhim kho thiab txhim kho cov kev kuaj mob tshiab thiab zoo dua.
Multifunctional off-board diagnostic system
Txhawm rau nthuav dav lub peev xwm kuaj mob thiab kuaj xyuas kev ua haujlwm ntawm on-board self-diagnosis system, nyob rau xyoo 1980s, Ford's off-board diagnostic instrument OASIS, Toyota's Diaqmonitor diagnostic system, Nissan's Consult, thiab lwm yam tau yug los ib zaug. Cov tshuab no muaj cov haujlwm ua tiav, tab sis tus nqi kuj tseem siab. Tus nqi kim, kev xav tau siab, thiab cov qauv tsis sib xws, yog li nws siv thiab kev saib xyuas kuj raug txwv qee yam. Tom qab nkag mus rau xyoo 1990, qee qhov kev kuaj mob ntau yam uas ua tau raws li cov qauv thoob ntiaj teb, yooj yim rau kev khiav lag luam thiab cov nqi tsim nyog tau tsim tiav. Xws li DOT-21 kev kuaj mob sab nraud tsim los ntawm Nyiv Daihatsu thiab lwm yam. Niaj hnub nimno automobile-diagnosis system yog ib tug self-muaj qhov system thiab tsis muaj universality, yog li nws tsis haum rau kev txhawb nqa, thiab nws tau ua rau muaj teeb meem loj hauv kev pab cuam tom qab muag thiab kev kho tsheb. Yog li ntawd, cov txheej txheem kev kuaj mob yuav tsum yog tus qauv, kom nws txoj kev kuaj mob thiab kev kuaj mob tuaj yeem sib koom ua ke, thiab tsuas yog ib qho cuab yeej siv tau los kuaj xyuas thiab kuaj xyuas ntau lub tsheb, uas yuav txhawb nqa kev txhim kho ntawm kev kho tus kheej ntawm lub tsheb.
Pom qhov txhaum
Cov theem teeb liab nkag mus rau microprocessor muaj qee qhov ntau yam nyob rau hauv ib txwm muaj. Yog hais tias lub teeb liab sab nraum qhov kev tawm tswv yim no, ECU yuav kuaj pom tias lub teeb liab system nyob rau hauv ib qho txawv txav. Piv txwv li, thaum lub cav txias dej kub teeb liab qhov system qhia tias qhov hluav taws xob ntawm lub sensor yog 0.08-4.8V thaum nws nyob rau hauv ib txwm muaj, nws raug kuaj pom tias txawv txav yog tias nws siab tshaj qhov no. . Yog tias lub microcomputer nws tus kheej tsis ua haujlwm, nws yuav raug saib xyuas los ntawm lub sijhawm txwv Circuit Court nrog lub sijhawm saib xyuas xwm txheej ceev; Yog tias muaj qhov kev ua haujlwm tsis zoo, qhov rov pib dua ntawm lub sijhawm txwv Circuit Court uas ua haujlwm ib ntus yuav tsum tsis ua haujlwm, yog li txhawm rau txais yuav qhov kev kuaj xyuas qhov yuam kev ntawm microcomputer pib dua.
Kev faib ua txhaum
Thaum lub microcomputer ua haujlwm ib txwm, qhov teeb meem txawv txav ntawm cov teeb liab tawm tswv yim raug kuaj pom los ntawm qhov kev kuaj mob, thiab tom qab ntawd raws li qhov kev tshawb pom, nws tau muab faib ua cov kev ua haujlwm me me uas yuav tsis raug cuam tshuam, kev ua tsis tiav uas ua rau kev ua haujlwm tsis zoo, thiab kev ua tsis tiav loj. Thiab qhov tsis raug yog cais raws li lawv qhov tseem ceeb, thiab lawv tau kho ua ntej hauv qhov program. Thaum lub microcomputer nws tus kheej ua tsis tiav, qhov ua txhaum loj raug cais los ntawm WDT.
yuam kev tswb
Feem ntau, tus tswv lub tsheb tau ceeb toom los ntawm qhov flashing ntawm lub teeb ceeb toom ntawm lub ntsuas ntsuas. Ntawm cov tsheb uas nruab nrog cov lus qhia, kuj tseem muaj cov ntawv qhia ncaj qha rau cov ntsiab lus ntawm lub tswb.
Kev daws teeb meem
Yog tias muaj kev txhaum tshwm sim thaum lub sijhawm ua haujlwm ntawm lub tsheb, txhawm rau kom tsis txhob cuam tshuam kev tsav tsheb ib txwm muaj, nws raug tswj hwm los ntawm microcomputer, thiab tus nqi surrogate nyob rau hauv pre-programmed program yog siv rau kev suav los tswj kev tsav tsheb yooj yim. Tom qab nres tsheb, tus tswv lossis cov neeg ua haujlwm tu yuav ua raws li kev saib xyuas.
