Yuav kom sib sau ua ke lub zog loj, npaj kho lub Circuit Court ntawm lub zog yav tom ntej. Txuag thiab luam tawm daim duab no, lossis pauv nws mus rau ntawv. Yog li, thaum daim duab nyob tom hauv ntej ntawm koj lub qhov muag, nws yuav yooj yim dua rau koj ua haujlwm.
Kauj ruam 10
Ua tib zoo saib daim duab. Txawm hais tias lub qhov muag liab qab nws tuaj yeem pom tias cov microcircuit siv hauv kev ua haujlwm muaj plaub ceg plaub ntawm txhua sab. Tag nrho ntawm yim ceg yog tau txais. Txhawm rau kom tsis txhob yuam kev lub microcircuit thiab tsis tig nws ntxeev siab, yog li ua yuam kev hauv soldering, ua tib zoo xav txog ntu. Rau kev yooj yim ntawm kev siv, ib lub cim me me uas zoo ib yam li ib nrab voj yog siv rau nws. Nthuav cov microcircuit kom lub cim no nyob saum.
Kauj ruam 11
Tam sim no pib soldering. Ua ntej koj yuav tsum solder thawj lub xov hlau, uas yuav mus rau qhov hloov thiab hu tau rau qhov zoo ntawm lub yas. Muag tus hlau no rau thib rau ceg ntawm lub microcircuit. Nws yog tus thib ob los hauv qab ntawm sab xis.
Kauj ruam 12
Muag rau lwm qhov kawg ntawm cov hlau mus rau qhov hloov. Tom qab soldering thawj lub xov hlau, txuas mus rau kauj ruam tom ntej. Tam sim no koj xav tau kev sib txuas lus thib ob ntawm tus tes hloov pauv, uas tam sim no pub dawb. Muag cov hlau tsis zoo tuaj ntawm qhov txuas ntawm lub hau rau ntawm hloov mus. Txog ntawm no ua ntej, qhov kev tsim ntawm lub tsev tsim cov tshuab kom nrov tau tuaj yeem ua tiav.
Kauj ruam 13
Tom qab ntawd, koj yuav tsum tau mus rau sab tom ntej ceg tom ntej ntawm lub microcircuit - thib tsib hauv kab (hauv daim duab nws yog qhia los ntawm tus lej 5), nws nyob hauv qab thib rau ceg, uas cov hlau twb tau muag ntawm thawj theem. Muag qhov davhlau ya nyob twg zoo ntawm tus capacitor mus rau tsib ceg.
Kauj ruam 14
Muag qhov seem tsis zoo lub davhlau ya nyob twg ntawm tus capacitor mus rau qhov zoo ntawm tus ntuav lus. Qhov no tuaj yeem ua ncaj qha. Tab sis qhov zoo tshaj plaws, txhawm rau txhawm rau tiv thaiv tus hais lus thiab capacitor los ntawm kev puas tsuaj, txuas lawv siv ib tus xaim ntxiv, uas koj yuav siv los ua kom ntev li ntawm qhov hu rau lub capacitor. Tom qab ntawd nws tsis zoo lub davhlau ya nyob twg ntawm tus capacitor mus rau qhov zoo ntawm tus ntuav lus.
Kauj ruam 15
Tom qab ntawd, txuas cov kev sib tiv tauj tsis zoo ntawm tus ntuav lus rau ob thiab plaub paws ntawm microcircuit. Hauv daim duab, cov no yog cov qis thiab thib ob los ntawm sab saum toj paws ntawm sab laug sab ntawm lub microcircuit. Solder tus hlau rau cov lus tsis zoo lub davhlau ya nyob twg. Tom qab ntawd txuas cov hlau no rau ceg plaub ceg ntawm microcircuit.
Kauj ruam 16
Siv jumper txuas txuas plaub thiab thib ob txhais ceg ntawm microcircuit. Ua li no, siv sij hawm luv luv. Muag nws rau plaub ceg plaub ntawm microcircuit (ib tus xaim twb txuas rau nws), thiab txuas rau lwm kawg ntawm cov hlau no rau sab ceg thib ob ntawm microcircuit.
Kauj ruam 17
Rau txhais ceg thib peb ntawm microcircuit, uas yog nyob nruab nrab ntawm ob tus neeg ua ntej nrog uas koj tau ua haujlwm tiav, koj yuav tsum solder lub resistor
Kauj ruam 18
Txuas cov xaim rau ntawm ob txhais ceg thib ob ntawm lub resistor, uas yuav txuas cov sib cuag zoo rau ntawm lub dav hlau me. Lub dav hlau me muaj ob qho kev sib cuag - txoj cai thiab sab laug. Txuas lawv ua ke thiab cam cov hlau uas mus los ntawm resistor mus rau pins.
Kauj ruam 19
Muag txoj hauv kev sib chwv ntawm lub dav hlau me me (thiaj li hu ua huab hwm coj) mus rau kev rho tawm ntawm tus hais lus Tam sim no yuav muaj tsuas yog rho tawm ntawm lub xov tooj txuas nrog nrog rho tawm ntawm kev hais lus.
Kauj ruam 20
Tom qab ua tiav cov kev yooj yim no, koj tau tsim ib qho yooj yim, tab sis muaj txiaj ntsig zoo, muaj suab nrov tuaj yeem siv tau rau lub ntsiav tshuaj lossis lub xov tooj smartphone.
