Ua ntej koj pib ntawm nws tus kheej tsim kev tsim qauv rau cov khoom siv hluav taws xob, koj yuav tsum kawm paub yuav ua li cas sib sau ua ke li cov khoom siv raws li cov qauv npaj tsim. Txhawm rau ua qhov no, koj yuav tsum paub qhov kev txawj ntawm soldering thiab nyeem ntawv lub voj voog.
Cov Lus Qhia
Kauj ruam 1
Yog tias koj tsis paub yuav ua li cas solder tsis tau, xyaum rau ntawm feem faulty. Nias qhov txhuas ntawm ib sab tiv thaiv cov txheej ntawm rosin hauv lub thawv, tom qab ntawd kov nws nrog cov taub hau ntawm hlau soldering kom nws me ntsis nqig hauv rosin. Tom qab ntawd, tshem cov hmoov txhuas los ntawm rosin, muab qee qhov muag ntawm qhov taub thiab khiav mus raws cov hmoov txhuas. Nws yuav tau tinted. Ua tib yam nrog cov hlau. Tom qab ntawd, quav cov hlau lead thiab cov hlau ua ke, thov rosin rau hauv kev sib tshuam nrog hlau soldering, thiab tom qab ntawd cam, thiab lawv yuav ua soldered. Tsuas yog tom qab nqa txoj haujlwm no rau automatism, pib sib sau ua ke ntawm Circuit Court los ntawm cov chaw pabcuam.

Siv phau ntawv siv, kawm paub muab cov lej ntawm daim duab sib piv nrog cov seem tiag. Tshawb nrhiav dab tsi lawv electrodes hu ua. Nws tseem ua tau los txiav txim seb qhov twg electrodes cov lus xaus ntawm ntu feem sib raug rau hauv txhua kis tshwj xeeb los ntawm phau ntawv hais txog. Nco ntsoov tias cov pinouts, txawm rau qhov chaw hauv tib lub tsev, muaj qhov sib txawv ntawm hom.
Kauj ruam 3
Ib rooj plaub tshwj xeeb tshwm sim thaum nruab microcircuits. Rau lawv, tus lej PIN yog qhia hauv daim duab, tab sis lawv tsis qhia ntawm microcircuits lawv tus kheej. Tso lub rooj plaub nrog daim ntawv lo tig ntsia, thiab coj tus pin uas nyob ib sab ntawm lub teev ua thawj tus. Cov pins uas tseem nyob yog suav ua ntsuas suav (thiab moos ntawm sab nraud ntawm pawg thawj coj). Thaum xub thawj, kom txog thaum koj paub yuav ua li cas sai sai, siv cov pob rau mounting microcircuits thiaj li tsis mus overheat lawv thaum soldering. Tsuas yog tom qab soldering lub qhov (socket), nruab lub caij rau nws.
Kauj ruam 4
Yuav khoom siv tshwj xeeb muab PCB. Muag khoom mus rau nws nyob rau hauv qhov kev txiav txim raws li hauv qab no: ua ntej, txhua yam tsis muaj zog (resistors, capacitors, txuas, thiab lwm yam), tom qab txiav tawm cov khoom siv semiconductor (piv txwv li diodes, transistors), ces microcircuits. Txuas lawv cov coj sab nraum qab ntawm lub rooj tsavxwm nrog cov xaim zoo tib yam. Thov nco ntsoov tias nws yog qhov tsim nyog dua rau nruab qee cov khoom ntxiv, piv txwv li, kev tswj hwm thiab ntsuas, sab nraum pawg thawj coj - ntawm phab ntsa ntawm rooj plaub.
Kauj ruam 5
Tam sim no ua tib zoo xyuas lub installation rau kev ua raws nrog daim duab hluav taws xob hauv Circuit Court thiab siv lub hwj chim rau cov txiag tiav.
