Nyob zoo phooj ywg hobbyist, Feem ntau ntawm peb paub tias kev siv tshuaj yaj yeeb tuaj yeem ua rau qee zaum txaus ntshai, qhov kev qhia no yuav pab koj kom pib thiab muaj cov cuab yeej zoo los tswj qhov txuj ci tseem ceeb no.

Kauj ruam 1: Yam Koj Yuav Tsum Tau

Cov khoom siv tseem ceeb:

+ Ib lub chaw Soldering zoo uas tso cai rau koj los tswj qhov ntsuas kub ntawm cov lus qhia soldering. Qhov no tau hais tias muaj lwm txoj kev xaiv pheej yig dua.

+ Cov xaim hluav taws xob uas muaj txoj kab uas hla me me tab sis tsis yog coj dawb, ceev faj!

+ Soldering hlau Ntsuas lub tshuab ntxhua khaub ncaws uas yuav ntxuav cov hlau ntxig los ntawm cov khoom seem.

+ Cov lus qhia ntxaum tinner uas tiv thaiv oxidation thiab tshem tawm txhua qhov seem. Qhov no yuav tso cai rau ncua kev siv tau ntawm koj cov lus qhia.

+ Desoldering braid rau lub hom phiaj rov ua haujlwm thaum ua yuam kev.

+ Flux uas pab txhawb kev ntws ntawm cov laug mus rau hauv lub ncoo/qhov lossis mus rau hauv qhov kev xav tau braid.

+ Ib txheej ntawm tweezers los tiv thaiv zoo li qub los tuav tag nrho SMD cov khoom.

+ Multimeter xav tau rau kev ntsuas txuas mus ntxiv thiab ntsuas dav dav ntawm lub rooj tsav khoom zaum kawg.

+ Solder cov pa nqus pa kom pa tawm cov pa phem tawm ntawm koj lub ntsej muag.

+ Lub chaw tsom iav tsom iav nrog tes clamps uas xav tau rau smd ua haujlwm raws li peb yuav muab tag nrho smd ua tus kheej hauv qhov kev qhia no.

Kauj Ruam 2: Npaj Npaj Rau Solder

Ua ntej peb pib siv 4 teev kev siv tshuaj yaj yeeb, nws yog qhov zoo kom paub tias koj yuav tsum tau ntsuas ntsuas zoo los lav koj li kev nyab xeeb. Kuv pom kab lus no uas piav qhia cov txheej txheem raug kom siv dav.

Qhov no tau hais, TL; DR version ntawm qhov no yog kom ntseeg tau tias koj ib puag ncig ua haujlwm tau zoo thiab tias koj muaj kiv cua tshuab cov pa phem ua pa tawm ntawm koj lub ntsej muag thaum ua haujlwm. Koj tuaj yeem mus tom ntej thiab yuav cov pa luam yeeb nqus nqus tau hais los saum no lossis koj tuaj yeem ua koj tus kheej los ntawm gluing ob yam hauv qab no ua ke:

+ Cov pa roj carbon lim.

+ PC kiv cua.

Ua li no, thov nco ntsoov cov lus qhia ntawm tus kiv cua. Koj xav nqus tag nrho cov pa luam yeeb rau hauv cov lim dej. Qhov teeb tsa DIY no tau siv hluav taws xob 12V-1A DC.

Kauj Ruam 3: Cuam Tshuam Los Ntawm Qhov Chaw (PHS)

Txog qhov sov sov kuv tau xaiv lub rooj sib tham yooj yim no, XR2206 lub tshuab hluav taws xob ua haujlwm, uas muaj ntau hom PTH sib txawv.

Tab sis ua ntej koj nkag mus rau hauv nws, Kuv pom zoo kom saib cov vis dis aus no los ntawm SparkFun Electronics uas piav qhia cov txheej txheem xav tau zoo heev. Lwm qhov ua kom sov zoo-teeb nws cov khoom siv oscilloscope, DSO 138.

Kauj Ruam 4: Soldering Lwm Yam PTH Cheeb Tsam

Hauv cov kauj ruam no koj xav nthuav tawm koj tus kheej kom tsis tshua muaj qhov sib xyaw. Kuv tau xaiv LM317 kho lub zog siv hluav taws xob uas muaj cov khoom siv xws li lub dab cua sov, hloov pauv thiab cov khej sib txuas uas nyuaj me ntsis rau cov laug. Cov khoom kawg kuj tseem muaj txiaj ntsig zoo thaum txhawb nqa Arduino/ RaspberryPi cov haujlwm.

Kauj Ruam 5: Cov Khoom Siv Hluav Taws Xob Mount (SMD)

Tam sim no koj tau xeb txaus los ntawm cov khoom (PTH). Nws yog lub sijhawm los ua qee yam khoom siv tsis txaus. Qhov no yuav tso cai rau koj los tsim lub zog tiv thaiv koj lub nraub qaum rau ib ntus saib ntawm lub iav tsom iav. Ua ntej koj pib, nco ntsoov tias koj qhov chaw ua haujlwm tau teeb pom kev zoo kom tsis txhob nkees sai. Tom qab ntawd, koj xav tshuaj xyuas Sparkfun qhia txog ob qho tib si ntawm kev siv tshuaj yaj ywm thiab ua kom tawv nqaij Deg Mount Devices (SMD).

Ntawm no kuv tau khaws cov Khoom Dot Matrix hauv qab no uas muaj ntau yam sib txawv SMD sib xyaw. Thaum kawg thaum tso Dot matrices rau ntawm lub rooj tsavxwm tseem ceeb, ua tib zoo saib xyuas qhov sib txawv ntawm cov cuab yeej ntawd raws li qhia hauv daim duab thib peb hauv liab.

Kauj Ruam 6: Cov Khoom Siv Lwm Yam SMD

Ib yam li peb tau ua nrog Kev hla ntu ntu, ntawm no, koj xav nthuav tawm koj tus kheej rau ntau yam ntxiv SMD yam. Kuv tau xaiv GSM-GPRS module rau lub hom phiaj no uas yuav siv rau hauv cov haujlwm tom ntej. Lwm qhov kev coj ua zoo yog txhawm rau rhuav tshem tag nrho Arduino Nano thiab muab nws rov qab rau hauv lwm lub pcb qhov (socket). Ua li no, koj yuav muaj peev xwm kawm paub ua siab ntev rau cov khoom siv hluav taws xob. Cov txuj ci no tseem ceeb heev tshwj xeeb tshaj yog tias koj ua yuam kev thaum siv cov khoom me me rau yav tom ntej.

Kauj Ruam 7: Xaus Qhov Kev Txiav Txim Nws

Soldering tuaj yeem ua rau txaus ntshai qee zaum, tab sis nrog cov cuab yeej raug thiab teeb tsa ua haujlwm raug koj tuaj yeem tig nws mus rau hauv kev lom zem los saib. Yog tias koj tau hla lwm cov khoom siv soldering zoo rau kev ua kom zoo sib xws, qhia rau kuv paub hauv cov lus hauv qab no.

Txog rau lwm lub sijhawm, nyob zoo!
