Koj puas yog Engineer?

Koj puas yog Hluav Taws Xob lossis tsuas yog tus nyiam ua haujlwm uas nyiam kho lawv cov khoom siv hluav taws xob lossis tsim ib qho?

Koj yuav hla cov txheej txheem hu ua "soldering" hauv koj lub neej, thiab ntawm no yog daim vis dis aus uas yuav pab koj muag txoj hauv kev.

Kauj Ruam 1: Kev Sawv Cev Yeeb Yaj Kiab

Kauj Ruam 2: Sau Cov Kev Xav Tau

1. Solder Iron / Solder chaw nres tsheb

ib qho cuab yeej siv hluav taws xob siv rau yaj yaj thiab siv nws rau cov hlau uas yuav tsum koom nrog.

(qhov cuab yeej tseem ceeb tshaj plaws)

2. Solder (muab hlau)

solder hlau yog ib qho hlau txuas rau koom nrog ob qhov chaw hlau los ntawm kev yaj cov hlau kom nws ua cov txheej nyias ntawm nruab nrab ntawm qhov chaw. Cov neeg muag muag muag yog cov hlau txhuas thiab tin; brazing solders yog cov hlau ntawm tooj liab thiab zinc qee yam uas koom nrog cov khoom ua ke khov kho

solder los hauv ntau hom, tab sis ntawm no, peb yuav siv cov tub ntxhais txuas hluav taws xob.

3.lub

cov dej ntws yog cov tshuaj ntxuav tshuaj, tus neeg sawv cev ntws, lossis tus neeg ua kom huv. Fluxes yuav muaj ntau dua ib txoj haujlwm ib lub sijhawm. Lawv tau siv hauv ob qho tib si tshem tawm cov hlau thiab hlau koom nrog.

ntawm no, hauv kev siv tshuaj yaj yeeb, peb siv cov dej ntws kom ntseeg tau tias tsis muaj oxidized solder sib koom ua ke.

4. Saib (ntub)

daim txhuam cev yog cov khoom muag muag uas muaj qhov me me thiab tuaj yeem nqus tau cov kua ntau, thiab tau siv

rau kev ntxuav thiab tu.

peb yuav siv qhov no los ntxuav qhov me ntsis

5. Solder Stand

nws yog siv los tuav cov laug cam kub.

6. Tweezers

tweezers yog ib qho cuab yeej me me zoo li ib khub pincers siv los khaws cov khoom me me.

7. De-Solder braid

De-soldering braid, tseem hu ua de-soldering wick lossis solder wick, tau ua kom zoo nkauj braided 18 txog 42 AWGCopper hlau coated nrog rosin flux, feem ntau yog muab rau ntawm yob, siv los tshem cov laug ntau dhau lossis tshem tawm cov khoom siv los ntawm pcb

8. Pab txhais tes (xaiv tau)

cov cuab yeej siv los tuav cov khoom lossis kev sib txuas hauv qhov chaw hla lub rooj ua haujlwm.

9. Fume Extractor (xaiv tau)

siv los tshaj tawm cov pa phem tsis zoo uas tsis xav tau kom deb ntawm tus neeg teb xov tooj.

Kauj Ruam 3: Soldering Wire

Thaum soldering hlau, Ua ntej tshaj plaws, Ua kom sov lub Solder Iron lossis teeb tsa koj lub Chaw Tuav Pov Hwm kom nyob ib puag ncig 350 ° C.

Rau qhov yooj yim siv ob lub xov hlau, Kuv yuav siv K hom Solder Bit.

1. Sawb ncig 10 hli ntawm rwb thaiv tsev ntawm ob qho kawg.

2. Twist cov xov hlau hauv ob txoj hauv kev no lossis txoj hauv kev ntawd, qhia hauv cov duab.

3. Thov me ntsis ntws.

4. Kov lub taub hlau mus rau xaim thiab tsis yog cov xaim tooj liab, thiab tam sim no npog tag nrho cov hlau siv cov muab tub lim hlau, piv txwv li xaim tooj liab, los ntawm maj mam thawb lub xaim, kom npog tag nrho.

5. Kuj tseem ntxuav qhov sib koom tes siv cawv cawv, kom tshem tawm cov dej seem.

Kauj Ruam 4: Cov Khoom Siv Hluav Taws Xob (THT) - Los Ntawm Qhov Tshuab

Txhawm rau muab cov khoom sib dhos tso rau ntawm Lub Rooj Tswjhwm Saib lub Hom Phiaj, lossis PCB, ua ntej Kub koj cov hlau txuas lossis chaw nres tsheb. Ib zaug ntxiv, siv hom k solder ntsis.

1. Thawb koj cov khoom mus rau qhov faib faib raws li qhov xav tau los ntawm cov phiaj xwm.

2. Tam sim no, tso qhov taub me ntsis ntawm cov hlau lead ntawm cov khoom tiv thaiv nyob ze ntawm lub lauj kaub laug thiab thawb cov hlau txuas kom maj mam txog thaum lub dav hlau tag nrho tau npog nrog cov hlau sib sau ua lub ntsej muag.

3. Siv cov dej ntws yog tias xav tau, koj tuaj yeem zam cov kauj ruam no, yog tias koj siv cov tub ntxhais txuas hluav taws xob.

4. Tam sim no, cia peb ntxuav lub davhlau ya nyob twg siv cov dej cawv ntxhua, kom tshem tawm cov seem uas seem.

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

Tam sim no, SMD Soldering yog cov txheej txheem sib txawv kiag li, vim tias qhov loj ntawm cov khoom sib txawv me me, thiab cov khoom yuav tsum tau teeb tsa saum npoo ntawm PCB ncaj qha, txoj haujlwm no tuaj yeem ua tiav los ntawm cov tshuab zoo nkauj.

Muaj ntau txoj hauv kev los sib dhos cov khoom SMD, tab sis peb yuav ua txoj haujlwm no siv peb cov hlau txuas.

A. Ob Cheeb Tsam Terminal (xws li Resistors, Capacitors, Etc)

1. Ua kom sov koj cov hlau txuas / teeb Koj Lub Chaw Tuav Pov Hwm rau 350 ° C txog 390 ° C nyob ntawm qhov sib xyaw. Ntawm no kuv tab tom siv hom C solder me ntsis, uas yog cov lus qhia zoo conical.

2. Ua ntej, siv me ntsis flux thiab cov laug rau ntawm lub lauj kaub laug ntawm PCB.

3. Tam sim no, nqa cov khoom siv siv tus tweezers rau ntawm lub ncoo sib txuas, ua kom sov ntawm lub davhlau ya nyob twg ntawm cov laug txuas, thiab cia nws txias ib txwm, hla ib qho ntawm lub davhlau ya nyob twg ntawm cov khoom siv

4. Tom qab ntawd, ua kom sov lwm lub lauj kaub kom sov, thiab koj yuav pom tias cov khoom siv tau txuas nrog rau qhov chaw.

5. Yog tias muaj qhov tsis meej pem me me, ua kom sov ob lub poom sib txuas ib txhij, cov khoom siv yuav zaum ntawm qhov chaw.

6. Ntxuav lub davhlau ya nyob twg siv cawv cawv, kom tshem tawm cov dej seem.

2. Ntau Qhov Chaw Tiv Thaiv (xws li IC)

1. Ua ntej, siv me ntsis flux thiab cov laug rau ntawm lub lauj kaub laug ntawm PCB.

2. Tam sim no, nqa tus tivthaiv uas siv tus tweezers rau ntawm daim kab xev solder

3. Txuas txhua sab ntawm IC ntawm daim kab xev. (Yeej luv Circuit Court)

5. Tam sim no, siv de-solder Copper Wick thiab tshem cov laug ntau dhau los ntawm cov dav hlau, siv me ntsis ntws.

6. Reheat txhua lub davhlau ya nyob twg kom paub tseeb tias kev sib txuas tau ua tiav ntawm txhua lub ncoo.

7. Txhawm rau tshem tawm ib qho luv luv Circuit Court, siv cov de-solder wick.

8. Ntxuav lub davhlau ya nyob twg siv cawv cawv, kom tshem tawm cov seem uas seem.
