Lub transistor yog ib qho tsim ua los ntawm cov khoom siv semiconductor nrog peb tus xaus. Nws tso cai rau cov phiaj xwm kev tawm tswv yim los tswj qhov tam sim no hauv hluav taws xob. Feem ntau, cov transistor siv los tsim, nthuav dav, thiab hloov hluav taws xob cov teeb liab.

Nws yog qhov tsim nyog

  • - soldering hlau;
  • - kws tu plaub hau.

Cov Lus Qhia

Kauj ruam 1

Siv cov thev naus laus zis hauv qab no los tua cov mosfet transistor. Siv ob tug kav hlau txuas mus rau qhov muag transistor. Ib qho yuav tsum nyob ntawm 65 W, tshav kub qhov chaw ntawm transistor nrog nws, qhov thib ob ntawm 36 W yuav tsum muaj qhov dav dav, tso cua sov ob qhov tawm ib zaug - qhov chaw thiab lub rooj vag.

Kauj ruam 2

Txhawm rau kom yooj yim dua mus rau lub cev transistor, thawj zaug sau qhov chaw nyob ib ncig ntawm lub mosfet nrog tus nqi me me ntawm rosin. Tom qab ua kom sov cov khoom siv ntawm cov transistor kom txog rau thaum cov khoom pib yaj, nrawm nyom cov ntaub ntawv mosfet nrog ob sab foob rau. Nws yuav ya tawm tsis deb mus rau sab.

Kauj ruam 3

Siv ib qho 40W soldering hlau. Ua kom sov siab thiab rub lub kaw thiab qhov chaw, tom qab ntawd nce qhov nqes dej, unsolder lub kaw thiab qhov chaw mus rau qhov kawg. Ntawm no koj yuav tsum pab koj tus kheej nrog tus txhuam hniav, tab sis ua txhua yam kom zoo, yog tias koj ua lub zog txav, koj tuaj yeem tsoo ceg ceg ntawm transistor.

Kauj ruam 4

Tseem ceeb tshaj: unsolder transistor kom cov tiv tauj tsis txhob tawm. Thaum koj sov lub ntws ntawm lub transistor, koj tuaj yeem tso ib daig ntawm nws thiab lub rooj tsavxwm, thaum nws haum tag nrho thiab cais cov ntws tawm ntawm lub rooj tsavxwm, tom qab ntawd cov ceg ntawm transistor tuaj yeem yooj yim tsis muaj qhov tawg ntawm lub cov ntaub ntawv.

Kauj ruam 5

Coj mus rhaub cov transistor siv rosin los yog roj roj thaum muaj kev phem tshaj plaws, los yog dej cawv rosin fluxes lossis soldering hlau qhov zoo tshaj plaws. Koj tuaj yeem sim ua kom solder lub transistor nrog rab phom cua kub zoo.

Kauj ruam 6

Siv cov ntawv ci los tiv thaiv cov khoom los ntawm qhov ua kom sov. Koj tuaj yeem tshem cov mosfets nrog tus tsim cov plaub hau: ua ntej cua sov, thov tso dej cawv rosin rau txhua lub davhlau ya nyob twg, sov nws hauv qab nrog tus kws caws plaub hau, ntawm qhov deb ntawm peb mus rau tsib centimeters.

Kauj Ruam 7

Thaum tus nplaim dej ya mus rau tus tiv tauj, nres cua sov thiab tshem cov transistor nrog tweezers. Txhawm rau tiv thaiv lub capacitors los ntawm overheating, ua rau cylindrical txhuas tiv thaiv los ntawm cov neeg tsis ua haujlwm lub zog. Yog tias koj ua kub ntxhiab hlau tso, muab tso rau ntawm cov thoob ze rau.
