1 check board method editing

1. Kev soj ntsuam txoj kev: seb puas muaj hluav taws kub, kub hnyiab, foaming, board breakage, socket xeb thiab dej.

2. Txoj kev ntsuas lub rooj: Txawm hais tias qhov ntxiv 5V, GND tsis kam yog tsawg dhau (hauv qab 50 ohms).

3. Kev kuaj xyuas fais fab: Rau lub rooj tsav xwm tsis zoo, qhov hluav taws xob siab tuaj yeem hloov kho me ntsis rau 0.5-1V. Tom qab lub hwj chim qhib, IC ntawm lub rooj tsavxwm tuav tau siv

los ua kom cov teeb meem nti kub, kom nws pom.

4. Logic cwj mem kos: xyuas seb lub teeb liab puas muaj zog lossis tsis muaj zog ntawm txhua qhov kawg ntawm IC input, tso zis, thiab tswj cov ncej uas xav tias yuav tsum tau.

5. Txheeb xyuas qhov chaw ua haujlwm tseem ceeb: Feem ntau lub rooj tsavxwm muaj kev faib tawm kom meej, xws li: cheeb tsam tswj (CPU), moos moos (crystal oscillator) (frequency division),

thaj chaw duab keeb kwm yav dhau, thaj chaw ua haujlwm (tus neeg, lub dav hlau), lub suab synthesis District, thiab lwm yam. Qhov no yog qhov tseem ceeb heev rau kev kho qhov tob ntawm lub computer board.

2 kev daws teeb meem txoj kev kho

1. Yuav xav tias lub nti, raws li cov lus qhia ntawm phau ntawv qhia, thawj zaug xyuas seb puas muaj lub teeb liab (waveform) ntawm cov tswv yim thiab cov zis terminals, yog tias muaj

yog tsis muaj input, ces kos lub IC tswj lub teeb liab (clock), thiab lwm yam. Yog hais tias muaj, qhov no IC yog phem Qhov ua tau zoo heev, tsis muaj teeb liab tswj, taug qab rau nws yav dhau los ncej kom txog rau thaum nws pom ib tug

puas IC.

2. Rau lub sijhawm no, tsis txhob tshem tus ncej ntawm tus ncej thiab siv tib tus qauv. Los yog IC nrog tib cov ntsiab lus ntawm qhov kev zov me nyuam nyob tom qab, thiab khau raj kom pom

yog tias nws zoo dua kom paub meej tias puas yog IC puas lawm.

3. Siv txoj kab tangential thiab jumper kab txoj kev los nrhiav cov kab luv luv: nrhiav qee cov kab teeb liab thiab hauv av, ntxiv rau 5V lossis lwm yam ntau yam ICs yuav tsum tsis txhob muaj.

txuas nrog lub luv luv Circuit Court, koj tuaj yeem txiav cov kab thiab ntsuas dua, txiav txim siab seb nws puas yog IC teeb meem lossis teeb meem ntawm lub rooj tsavxwm, lossis qiv nyiaj

los ntawm lwm yam ICs mus rau solder rau IC nrog lub waveform tsis ncaj ncees lawm kom pom tias daim duab zoo dua, thiab txiav txim seb IC puas zoo lossis phem.

4. Txoj kev tswj hwm: Nrhiav lub khoos phis tawj zoo nrog cov ntsiab lus tib yam los ntsuas tus pin waveform ntawm cov sib txuas IC thiab tus lej ntawm IC kom paub meej

seb IC puas.

5. Kuaj IC nrog ICTEST software hauv microcomputer universal programmer (TXOJ-03/07) (EXPRO-80/100, thiab lwm yam).

3 tshem tawm txoj kev kho

1. Txoj kev shearing: tsis muaj kev puas tsuaj rau lub rooj tsavxwm, tsis tuaj yeem rov ua dua.

2. Luag cov txheej txheem tin: solder lub tin ntawm ob sab ntawm IC tus pin, siv cov kub kub soldering hlau los rub rov qab, thiab pib lub IC (yooj yim puas.

lub rooj tsavxwm, tab sis tuaj yeem tiv thaiv qhov ntsuas IC).

3. Cov txheej txheem barbecue: grilling ntawm lub teeb cawv, lub qhov cub roj, lub qhov cub hluav taws xob, thiab lwm yam. Tom qab cov tin melted ntawm lub rooj tsavxwm, IC yog tsim (tsis yooj yim rau tuav).

4. Tin lauj kaub txoj kev: Ua ib lub lauj kaub tshwj xeeb ntawm lub cub hluav taws xob. Tom qab cov tin melted, IC yuav tsum tau muab tshem tawm ntawm lub rooj tsavxwm yog raus rau hauv lub lauj kaub, thiab IC.

tuaj yeem raug tshem tawm yam tsis muaj kev puas tsuaj rau lub rooj tsavxwm, tab sis cov khoom siv tsis yooj yim rau kev tsim khoom.

5. Cov phom hluav taws xob hluav taws xob: Siv rab phom hluav taws xob tshwj xeeb los tshem cov yeeb yaj kiab, tshuab ib feem ntawm IC kom tshem tawm, thiab tom qab ntawd IC tom qab lub tin tuaj yeem muab tshem tawm (ceeb toom

tias rab phom cua yuav tsum tau shaken thaum lub phaj yog tshuab, txwv tsis pub lub tshuab computer yuav raug tshuab. Txawm li cas los xij, tus nqi ntawm rab phom cua yog siab, feem ntau hais txog

2,000 yuan.) Raws li kev kho kho vajtse, kev kho vaj tse yog ib qho tseem ceeb tshaj plaws. Tom qab ntawd, coj ib tug faulty motherboard, yuav ua li cas los txiav txim

yam khoom twg muaj teeb meem?

4 tsis ua hauj lwm lub ntsiab yog vim li cas editor

1. Man-made faults: ntsaws rau hauv I/O phaib nrog lub hwj chim, thiab kev puas tsuaj rau cov interfaces, chips, thiab lwm yam. tshwm sim los ntawm kev quab yuam tsis zoo thaum thauj cov boards thiab plugs.

2. Ib puag ncig tsis zoo: hluav taws xob zoo li qub feem ntau ua rau cov nti ntawm lub motherboard (tshwj xeeb tshaj yog CMOS nti) tawg. Tsis tas li ntawd, thaum lub motherboard

ntsib ib qho kev puas tsuaj ntawm lub hwj chim los yog ib qho spike generated los ntawm daim phiaj voltage, nws feem ntau puas lub nti nyob ze ntawm lub hwj chim plug ntawm lub system board. Yog hais tias lub motherboard

yog npog nrog plua plav, nws tseem yuav ua rau lub teeb liab luv luv. 3. Cov teeb meem tsis zoo ntawm cov cuab yeej: Kev puas tsuaj vim tsis zoo ntawm cov nti thiab lwm yam khoom siv. Thawj qhov yuav tsum nco ntsoov yog

uas plua plav yog ib qho ntawm cov yeeb ncuab loj tshaj plaws ntawm lub motherboard.

Cov lus qhia

Cov lus qhia ua haujlwm (3)

Nws yog qhov zoo tshaj plaws los saib xyuas cov plua plav. Siv txhuam txhuam kom maj mam txhuam cov hmoov av ntawm lub motherboard. Tsis tas li ntawd, qee daim npav ntawm lub motherboard thiab chips yog nyob rau hauv daim ntawv ntawm tus pins,

uas feem ntau ua rau kev sib cuag tsis zoo vim oxidation ntawm cov pins. Siv cov nplaum los tshem tawm cov txheej oxide saum npoo thiab rov ntsaws nws. Tau kawg, peb tuaj yeem siv trichloroethane--evaporation*,

uas yog ib qho ntawm cov kua siv los ntxuav lub ntsiab board. Kuj tseem muaj lub zog tsis ua haujlwm tam sim ntawd, koj yuav tsum tua lub computer tam sim ntawd, kom tsis txhob dheev hu rau lub motherboard

thiab fais fab mov hlawv. Vim yog qhov teeb tsa BIOS tsis raug, yog tias overclocking ... koj tuaj yeem dhia kom tshem cov kab thiab khaws nws dua. Yog hais tias lub BIOS yog corrupted, xws li ib tug kab mob nkag mus ...,

koj tuaj yeem rov sau dua BIOS. Vim tias BIOS tsis tuaj yeem ntsuas los ntawm qhov ntsuas, nws muaj nyob rau hauv daim ntawv ntawm software. Txhawm rau tshem tawm txhua yam uas yuav ua rau muaj teeb meem

Nyob rau hauv lub motherboard, nws yog qhov zoo tshaj plaws los txhuam lub motherboard BIOS. Muaj ntau yam laj thawj rau lub host system ua tsis tiav. Piv txwv li, lub motherboard nws tus kheej los yog ntau yam ntawv tsis ua hauj lwm rau

lub tsheb npav I/O tuaj yeem ua rau lub cev ua haujlwm tsis zoo. Txoj kev kho plug-and-play yog ib txoj hauv kev yooj yim los txiav txim qhov txhaum ntawm lub motherboard lossis I / O ntaus ntawv. Txoj kev

yog kaw lub plug-in board ib tug los ntawm ib tug, thiab txhua lub sij hawm ib tug board raug rho tawm, lub tshuab yog khiav los soj ntsuam lub khiav lub xeev ntawm lub tshuab. Thaum lub rooj tsavxwm ua haujlwm

Feem ntau tom qab rub tawm ib qho thaiv, qhov txhaum yog tshwm sim los ntawm kev ua txhaum ntawm lub rooj tsavxwm lossis qhov sib thooj I / O tsheb npav. Thiab lub load Circuit Court yog faulty. Yog hais tias qhov system pib yog tseem

Tsis zoo li qub tom qab tag nrho cov boards raug tshem tawm, qhov txhaum yog yuav nyob rau ntawm lub motherboard. Txoj kev sib pauv yog qhov pib los pauv tib hom plug-in board, tsheb npav

hom yog tib yam, tib lub luag haujlwm ntawm lub rooj tsavxwm plug-in los yog tib hom nti kev sib tshuam nti pauv, raws li kev hloov pauv ntawm qhov tshwm sim txhaum cai los txiav txim qhov txhaum.

Txoj kev no feem ntau yog siv nyob rau hauv ib qho yooj yim-rau-plug txij nkawm ib puag ncig, xws li kev nco nws tus kheej tsis raug, uas tuaj yeem pauv tib lub cim xeeb.
