Kev kho cov niam tsev ntawm lub khoos phis tawj thiab lub laptops niaj hnub no yog qhov tseem ceeb ntawm cov kev pabcuam cov chaw pabcuam. Qhov no yog vim muaj cov qauv tsim ntawm cov cuab yeej ntawm cov laug cam, sib sau ua ke raws li tus txheej txheem thaum lub tshuab ntaus ntawv, daim npav video thiab lwm qhov tseem ceeb ntawm cov kab ke ua ke ntawm ib daim txiag. Qee qhov xwm txheej, kev tiv thaiv kev kho mob thiab kho me me rau cov niam tsev tuaj yeem nqa tawm ntawm nws tus kheej, muaj riam phom nrog hlau tsis zoo.

Cov Lus Qhia
Kauj ruam 1
Yog tias ib qho ntawm cov khoom siv ntawm motherboard malfunctions, nws feem ntau tsis paub mus hloov nws kiag li. Hauv qhov no, kho nws nrog kev hloov ntawm cov ua txhaum. Qee qhov xwm txheej, txawm li cas los xij, kev kho yuav zoo dua li hloov lub rooj tsavxwm. Tsuas yog cov kws tshaj lij pabcuam tau tuaj yeem txiav txim siab qhov teeb meem loj npaum li cas.
Kauj ruam 2
Kaw lub cuab yeej thiab ntxuav cov motherboard uas lo av. Ua li no, siv cov kua tshwj xeeb (solvent, cawv lossis acetone). Kev ntxuav nws tus kheej tuaj yeem txo qhov peev xwm ntawm kev ncig luv luv.
Kauj ruam 3
Ua tib zoo tshuaj xyuas cov khoom sib txuas ntawm pawg thawj coj thiab cov khoom sib txuas ntawm lawv. Tshawb xyuas kev ncaj ncees ntawm cov coj thiab ua zoo xyuas cov ntawv coj ua. Txhawm rau pab tshawb xyuas, tsom lub rooj tsav xwm los ntawm sab rov qab rau cov qauv luam ntawv. Qhov no yuav pab txhawm rau txiav luv thiab tawg hauv cov conductors. Ua tib zoo tshem tawm cov kev ua txhaum uas sau tseg los ntawm kev rov tiv tauj nrog tus hlau soldering.
Kauj ruam 4
Ntxiv nrog rau qhov chaw uas tau ntsia ncaj qha rau ntawm lub rooj tsavxwm, hauv Circuit Court kuj muaj cov ntu uas txuas ntawm sab nraud (piv txwv, cov ntsuas hluav taws xob). Kuj kuaj lawv kom zoo, thiab yog tias muaj kev puas tsuaj rau qhov muag pom, unsolder lawv los ntawm lub rooj tsavxwm thiab hloov nrog cov kev pabcuam.
Kauj ruam 5
Txhawm rau kom paub tseeb tias cov kev sib txuas koj tau ua yog lawm, xyuas cov khoom sib sau ua ke tawm tsam cov qauv txuas ntawm sab nraud uas muaj nyob nrog phau ntawv sib dhos. Them nyiaj tshwj xeeb rau kev muab hluav taws xob.
Kauj Ruam 6
Nco ntsoov xyuas cov ntsiab lus uas koj rov tsim rau hauv pawg thawj coj saib ua ntej sib txuas. Siv lub multimeter (tester) rau qhov no. Lawv tuaj yeem kuaj cov resistors raws li tau zoo xws li capacitors. Nco ntsoov tias cov seem hloov yog ntawm hom thawj thiab kev ntaus nqi.
Kauj Ruam 7
Thaum soldering lub motherboard, koj yuav tsum ntsib qhov teeb meem ntawm "thib peb", uas feem ntau tsis txaus los tuav cov ntu los txuas nrog. Rau lub hom phiaj no, siv qhov yooj yim me me khej kauv clip, yav dhau los nws ruaj khov nws sawv. Clamp ib qho ntawm seem kom tau soldered hauv lub cuab yeej, thiab tuav lwm qhov nrog koj txhais tes lossis tweezers.
Kauj ruam 8
Txhawm rau txuas lub neej ntawm pawg thawj coj saib, nias lub pob tshab yas pob tshab rau nws. Ua ntej qhov no, so lub getinax nrog cov ntxhia roj, muab zaj duab xis tso rau, tom qab ntawd tso cov duab kos nrog cov qauv hauv qab thiab muab nws npog nrog txhua daim ntawv. Ua kom sov tag nrho cov qauv nrog hlau kub kom txog thaum cov ntawv hloov lub teeb xim av.
