Zoo heev yog li ntawd soldering yog qhov yooj yim zoo rau hla dhau qhov khoom, tab sis tom qab ntawd muaj qee lub sijhawm thaum koj xav tau mus me me *ntxig rau tus txiv neej siv ntawm no *, thiab cov txuj ci uas koj tau kawm rau TH soldering tsuas yog tsis siv ntxiv lawm. Zoo siab txais tos rau lub ntiaj teb ntawm Cov Khoom Siv Hluav Taws Xob Mount (SMD), qhov chaw sib xyaw tau muab tso rau ntawm cov pawm me me, thiab muab tshuaj txhuam rau ntawm cov pawm yog rov ua kom sov cov khoom sib txuas rau lub rooj tsavxwm. Nws suab nyuab… tab sis nws tsis tas yuav.

Cia peb pib.

Auj, yog tias koj tsis nyiam nyeem ntau lo lus, thiab yog ib tus neeg muaj yees duab ntau dua, Kuv tau txais nws tag nrho hauv cov vis dis aus!

Thawj qhov koj xav ua yog xaj cov khoom, uas yuav tsum muaj qee qhov txuj ci (qhov loj me, hom, ncoo loj, thiab lwm yam yuav tsum tau txiav txim siab). Nws yog qhov zoo tshaj kom muaj BOM ntawm tes thiab xaj kom haum. Nrog rau cov khoom xaj, koj yuav xav tau lub rooj tsav xwm zoo.

Kuv xaj kuv cov laug cam los ntawm kuv cov chaw tsim khoom ntseeg PCBway.com.

Tsis tsuas yog lawv muab cov laug cam zoo tshaj plaws nrog cov qauv zoo tshaj plaws, tab sis lawv kuj muaj pab pawg txhawb nqa txhawm rau txheeb xyuas qhov kev txiav txim rau kev ua tsis raug thiab qhia raws li. Lawv kuj tseem muab cov stencils zoo tshaj mus nrog koj cov laug cam PCB (ntau dua ntawm stencils tom qab). Lawv cov laug cam pib ntawm tsuas yog $ 5! Xyuas lawv tawm ntawm no.

Tam sim no, pom tseeb tias ib txwm siv cov hlau txuas thiab cov laug yuav tsis ua, koj yuav xav tau cov khoom siv, yog li ntawm no yog cov npe:

Khoom siv

1. PCB
2. Stencil (pom zoo thaum cov khoom sib koom ua ke hauv thaj chaw me me).
3. Cov cua kub yaj phom
4. Soldering Microscope
5. Solder Paste (khaws nws hauv lub tub yees, tab sis nyob deb ntawm cov khoom noj thov!)
6. Spatula (lossis daim npav yas ib txwm muaj).
7. Ib khub tweezers
8. Isopropyl cawv
9. Ua siab ntev ntau

Kauj Ruam 1: Tshawb xyuas thiab ntxuav PCB

PCBs feem ntau tuaj nqus thiab tiv thaiv txheej. Nws yog ib qho tseem ceeb heev ua ntej yuav tau ntxuav cov PCB nrog qee cov cawv isopropyl.

Tom qab ntxuav thiab qhuav, tshuaj xyuas nws hauv qab lub tsom iav. Sib piv cov pawm, cov vias, cov cim, kom ntseeg tau tias nws sib phim nrog cov phiaj xwm phiaj xwm muab rau cov chaw tsim khoom. Kuj xyuas kom cov ntaub qhwv tau zoo thiab khov kho ntawm lub rooj tsavxwm, thiab tsis rub tawm.

Kauj Ruam 2: Thov Muab Tshuaj Txhuam Luam Luam rau PCB

Rau lub pcb me me nrog ob peb yam khoom, koj tuaj yeem tsuas kis tau muab tshuaj txhuam tso rau ntawm cov ntaub qhwv tus kheej, tab sis rau PCBs nyuaj, tus stencil, raws li qhia hauv daim duab, xav tau.

Thaum koj muaj lub rooj tsav xwm ruaj khov tuav ntawm lub rooj (raws li qhia), tso lub stencil hla nws, thiab siv me ntsis ntawm cov tshuaj txhuam txhuam. Tshaj tawm cov tshuaj txhuam siv cov spatula, thiab ua kom ntseeg tau tias txhua qhov qhib ntawm lub stencil tau npog nrog cov tshuaj txhuam. Tam sim no ua tib zoo tshem cov stencil.

Tsis txhob txhawj xeeb yog tias koj tsis tau txais nws yog thawj ob peb zaug. Tsuas yog so lub rooj tsavxwm thiab sim dua!

Kauj Ruam 3: Muab Cov Khoom Siv

Tam sim no los txog txoj haujlwm txaus ntshai tshaj plaws: Muab cov khoom tso rau ntawm lub rooj tsavxwm.

Nov yog kuv qhov kev koom ua ke tso kev ua yeeb yam:

Kuv muaj daim ntawv loj (A4) ntawm lub rooj teeb tsa nrog cov cim cim ntawm nws, thiab daim ntawv loj ntawm cov khoom siv lawv tus kheej ntawm lub rooj (Koj tuaj yeem pom nws hauv daim duab nrog lub tsom iav).

Thaum kuv tso ib qho kev tivthaiv, kuv hla yog tawm ntawm ob daim ntawv. Txoj kev no, kuv tiv thaiv kev ua yuam kev, poob, lossis tsis nco qab cov khoom.

Kauj ruam 4: Rov ua dua

Thaum cov khoom muaj nyob hauv qhov chaw, nws yog lub sijhawm rau peb rov ua dua peb lub lauj kaub. Qhov no tuaj yeem ua tiav hauv 2 txoj hauv kev:

1. Siv lub qhov cub ci rov qab: Zoo dua tab sis kim
2. Siv rab phom phom kub kub: Tsis kim tab sis qhov tseeb nyob ntawm tus neeg siv.

Peb yuav mus nrog Cov cua kub yaj vim tias nws pheej yig, thiab ua haujlwm yuav luag ib yam nkaus!

Yog li kuv pib muab cov hlau rau 180 degress C, thiab preheat lub rooj tsavxwm txog li ib feeb.

Qhov no yog txhawm rau tiv thaiv cov khoom siv nquag los ntawm kev poob siab cua sov. Thaum ua tiav, nws yog lub sijhawm rov ua dua!

Nws yog ib qho tseem ceeb los saib cov ntaub ntawv rov qab ntawm txhua yam ntawm koj cov khoom, saib seb koj tuaj yeem sov koj cov khoom rau ntev npaum li cas, thiab nyob ntawm qhov kub li cas. Kuv feem ntau tsuas yog "tis nws", thiab sov lawv li ntawm 270C, txog li ib feeb. Koj yuav pom cov laug yaj yaj, thiab cov khoom sib txuas tau muab tso rau hauv lawv qhov chaw. Thov saib qhov tshwm sim ntawm daim vis dis aus.

Kauj Ruam 5: Kuaj Kuaj Kawg thiab Ntxuav

Thaum rov ua kom tiav, nws yooj yim heev rau xav tias qhov ua tiav yog qhov zoo, txawm li cas los xij, tuaj yeem muaj ntau qhov seem seem seem, thiab txuas kev sib txuas ntawm cov laug cam. Muaj peev xwm tuaj yeem tshem tawm nrog cov kua tshuaj solderng, tab sis qhov ntawd yog qhov teeb meem rau kev qhia sib txawv. Vam tias koj nyiam qhov no!

Raws li cov cim ntawm kev txaus siab, Kuv yuav nyiam nws yog tias koj tau mus ntsib kuv li channel thiab tau sau npe rau nws.

Khaws Fungineering!
