7. Kev Paub Txog

Yuav ua li cas Debug ib tug tshiab tsim PCB Board

Cov lus qhia thiab cov hau kev hauv qab no yog raws li kev paub dhau los thiab tsim nyog kawm. Thaum tsim ib lub PCB, ntxiv rau kev txawj siv kev kos duab software, koj xav tau cov kev paub theoretical thiab kev ua haujlwm ntawm tes. Cov no tuaj yeem pab koj ua tiav koj tus qauv PCB sai thiab ua tau zoo. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum tau ceev faj; txawm nyob rau hauv kev sib txuas los yog kev teeb tsa, txhua kauj ruam yuav tsum tau saib xyuas. Qhov yuam kev me me tuaj yeem ua rau cov khoom tsis ua haujlwm kawg. Yog li ntawd, nws tsim nyog siv sij hawm ntxiv los xyuas cov ntsiab lus kom zoo es tsis txhob maj nrawm ntawm cov txheej txheem tsim. Zuag qhia tag nrho, PCB tsim qhia tshwj xeeb rau kev nthuav dav.

Rau cov neeg tsim qauv PCB, kev debugging feem ntau tsim nyog, tshwj xeeb tshaj yog rau cov laug cam tshiab. Cov no tuaj yeem nyuaj rau kev daws teeb meem, tshwj xeeb tshaj yog thaum lub rooj tsavxwm loj, thiab cov khoom siv tau yooj yim. Txawm li cas los xij, muaj ib txoj hauv kev debugging tuaj yeem ua rau cov txheej txheem ua tau zoo dua.

Rau lub rooj tsavxwm PCB tshiab, pib los ntawm kev tshuaj xyuas nws rau cov teeb meem pom tseeb xws li cov kab nrib pleb, luv luv, lossis qhib circuits. Yog tias tsim nyog, xyuas kom meej tias qhov kev tiv thaiv ntawm lub hwj chim thiab hauv av yog txaus.

Tom ntej no, pib nrog kev teeb tsa kev teeb tsa. Rau cov qauv ywj pheej, zam kev txhim kho txhua yam ib zaug yog tias koj tsis paub tseeb tias lawv ua haujlwm raug. Hloov chaw, txhim kho cov khoom sib txuas ntxiv (rau cov kab hluav taws xob me, koj tuaj yeem nruab lawv tag nrho ib zaug), tso cai rau kev sib cais yooj yim dua. Feem ntau, pib nrog lub hwj huam mov module thiab xyuas seb qhov tso zis voltage yog li cas. Thaum lub hwj chim rau thawj zaug, xav txog kev siv tam sim no-txhim kho lub zog hloov tau. Teem lub overcurrent tiv thaiv, ces maj mam nce qhov voltage thaum saib xyuas cov input tam sim no, input voltage, thiab output voltage. Yog hais tias tsis muaj overcurrent thiab cov zis voltage yog lawm, lub hwj huam mov yuav ua hauj lwm zoo. Txwv tsis pub, disconnect lub hwj chim thiab teeb meem.

Txuas ntxiv los ntawm kev txhim kho lwm cov modules incrementally, powering on and checking every module to prevent overcurrent or component burnout vim tsim los yog installation yuam kev.

Methods for Identifying Faults:

1, Kev ntsuas qhov ntsuas hluav taws xob

• Pib los ntawm kev lees paub tias qhov hluav taws xob muab hluav taws xob ntawm txhua tus pin pin yog qhov tseeb. Tshawb xyuas seb qhov kev siv hluav taws xob puas yog raws li qhov xav tau thiab qhov ua haujlwm voltages ntawm txhua qhov chaw nyob hauv qhov qub. Piv txwv li, rau ib tug raug silicon transistor, BE junction voltage yog hais txog {{0}}.7V, thiab CE junction voltage yog hais txog 0.3V los yog tsawg dua. Yog tias lub transistor's BE junction voltage tshaj 0.7V (tshwj tsis yog cov xwm txheej tshwj xeeb xws li Darlington transistor), BE junction yuav qhib.

2, Kev Txhaj Tshuaj Txhaum Cai

• Txhaj ib lub teeb liab ntawm lub tswv yim thiab ntsuas lub waveform ntawm txhua qhov taw tes txhawm rau txheeb xyuas qhov chaw txhaum. Cov txheej txheem yooj yim dua tuaj yeem koom nrog kov cov tswv yim ntawm txhua theem nrog koj tus ntiv tes los soj ntsuam cov txiaj ntsig tso tawm, uas tuaj yeem pab tau rau lub suab thiab video amplifiers. (Faj seeb: Qhov no yuav tsum tsis txhob ua nrog high-voltage circuits los yog cov uas muaj ib tug kub backplane, vim hais tias nws yuav ua rau hluav taws xob shock.) Yog hais tias tsis muaj cov tshuaj tiv thaiv nyob rau hauv lub dhau los theem tab sis muaj ib tug tshwm sim nyob rau hauv lub tom ntej no, qhov teeb meem yuav lies. nyob rau theem dhau los.

3, Kev Tshawb Nrhiav Kev Ua Phem Ntxiv

Lwm cov txheej txheem suav nrog kev tshuaj xyuas qhov muag, mloog, hnov ​​tsw, thiab kov:

• Saibrau lub cev puas tsuaj, xws li tawg, blackening, los yog deformation.
• Mloograu cov suab txawv txawv, raws li ib yam dab tsi uas yuav tsum ua haujlwm ntsiag to tuaj yeem qhia qhov teeb meem yog tias nws ua suab nrov lossis xav tias lub suab tsis tuaj lossis txawv txav.
• Tsis hnov ​​tswrau cov cim qhia ntawm overheating, xws li hlawv cov ntxhiab los yog cov ntxhiab ntawm capacitor electrolyte, uas tus kws tshaj lij tuaj yeem tshawb pom.
• Kovlos xyuas seb cov khoom puas nyob ntawm qhov kub thiab txias, vim qee cov khoom siv hluav taws xob ua kom sov thaum ua haujlwm. Yog tias lawv txias, lawv yuav tsis ua haujlwm. Ib yam li ntawd, yog tias ib qho khoom siv kub heev, nws yuav qhia tau tias ua haujlwm tsis zoo. Ib txoj cai dav dav yog tias lub hwj chim transistors thiab voltage regulators yuav tsum ua hauj lwm hauv qab 70 degree, uas koj tuaj yeem tshawb xyuas los ntawm tuav koj txhais tes nyob ze lawv luv luv (sim ua tib zoo kom tsis txhob hlawv).

Kev debugging lub rooj tsav xwm tsim tshiab tuaj yeem nyuaj, tshwj xeeb tshaj yog nrog cov qauv loj lossis cov qauv tsim. Tab sis nrog txoj hauv kev tsim thiab kev saib xyuas kom meej, cov txheej txheem tuaj yeem tswj tau.
