Siv Lub Tshuab Hluav Taws Xob kom tshem tawm/ tshem tawm qhov seem ntawm PCB qub lossis tawg.

Kuv siv lub harddrive qub los ua piv txwv. Koj tuaj yeem khaws feem ntau ntawm txhua qhov chaw, BGA lossis txawm tias dhau los ntawm qhov siv qhov no.

Kauj Ruam 1: Tshem PCB los ntawm Lwm Cov Casings

Tshem PCB los ntawm Lwm Cov Casings
Tshem PCB los ntawm Lwm Cov Casings

Ua ntej tshem PCB los ntawm ib qho casings.

Ntawm no kuv tsuas muaj ob peb screws tshem tawm.

Kauj Ruam 2: Tshav Kub Kub Thaj Chaw Siv Heatgun

Tshav Kub Hauv Cheeb Tsam Siv Heatgun
Tshav Kub Hauv Cheeb Tsam Siv Heatgun

Tam sim no koj yuav ua kom sov thaj tsam nrog rab phom cua sov. Kuv yuav hais qhia siv qee yam uas tsis kub hnyiab kom muab cov khoom tso rau thiab muab tso rau ntawm lub kaum sab xis kom ua haujlwm nrog. Kuv siv rooj plaub qub los tiv thaiv lub rooj ntev zaum. Koj tseem yuav xav kom ntseeg tau tias tsis muaj ib yam uas tuaj yeem yaj lossis hlawv hauv thaj tsam ib puag ncig nws.

Ntawm no kuv yuav ua kom sov thaj tsam ib puag ncig cov xim SMT daj nyob rau saum kaum sab laug. Tom qab cua sov thaj chaw. Saib cov laug kom tig los ci kom pom tias nws ntws, Koj tuaj yeem tshem tawm qhov uas siv tus tweezers lossis rab koob lub qhov ntswg. Tom qab ntawd muab tso rau hauv qhov chaw nyab xeeb kom txias. Ua tib zoo saib xyuas tshwj xeeb nrog cov ntu me me lossis cov khoom uas tuaj yeem ua kom sov sov. Cov cua los ntawm cov cua sov tuaj yeem tshuab qhov me me nyob ib puag ncig. Koj kuj tsis xav kom hlawv qhov uas koj tab tom sim txuag.

Kauj Ruam 3: Tshooj raug tshem tawm

Qhov Tshem Tawm
Qhov Tshem Tawm

Tam sim no koj tau tshem cov ntu uas koj xav tau. Cia lub rooj tsavxwm txias thiab ua raws li qhov koj xav tau.

Daim duab no qhia cov khoom raug tshem tawm. Kuv tau tshem tawm qhov hla, BGA, SMT qhov chaw siv txoj hauv kev no. Rau qee qhov cua sov sab nraum qab ntawm PCB thiab cia cov khoom poob qis tuaj yeem nrawm dua. Qhov no tsuas yog ua haujlwm nrog ntu loj txaus kom poob. Tsis tas li kuv tau pom qee qhov seem zoo li tau lo rau ntawm lub rooj tsavxwm thiab nyuaj rau tshem tawm. Yog li ceeb toom.

Nov yog qee qhov uas kuv tshem tawm ntawm HDD PCB. Hauv daim duab no kuv pom IC's, SMT transistors, capacitors, thiab diodes.
