Soldering smd yog ua los ntawm cov tshuab tab sis ua siab ntev me ntsis thiab xyaum txhua tus tuaj yeem ua nws los ntawm tes.so hauv cov lus qhia no kuv yuav qhia koj yuav ua li cas txhawm rau smd.

Kauj Ruam 1: Cov Cuab Yeej Xav Tau

1) Cov ntsuas kub tswj cov ntsuas kub

2) Kuv nyiam siv 0.015 ″ 60/40 cov hmoov txhuas

3) solder wick los yog pumb

4) Tweezers

5) flux

6) Rhuav cawv

7) Cov ntaub ntub dej

Kev siv cov ntsuas kub tswj cov hlau yog qhov zoo tshaj plaws tab sis ib txwm siv cov hlau ua haujlwm zoo.iam siv tib lub tiaj tiaj rau cov hlau Kuv pom zoo kom siv cov lus qhia ntxaws. Kev siv cov hlau lead ua kom txoj haujlwm yooj yim dua cov hlau lead dawb thiab tsis muaj cov hmoov lead dawb xav tau kub ntau dua li cov hlau lead.you koj siv lub lauj kaub los yog lub twj tso kua mis. Kuv siv rab koob tweezer.us siv lub zog thaum tsim nyog.

Kauj Ruam 2: Nyem Qhov Ntsuas

Ua ntej koj yuav tsum tau tin qhov taub. Yog tias koj tsis tin qhov nws yuav oxidized. Rau tining koj xav tau daim txhuam cev ntub. Lub koj cov hlau hauv daim txhuam cev ntub thiab yaj me ntsis rau ntawm cov hlau. Qhov no hu ua tinning thiab nws yuav pab kom cov cua sov ntws los ntawm cov hlau taub mus rau qhov sib koom. Lub lauj kaub yuav tsum ntws mus rau qhov taub, ua rau lub ntsej muag ci ci. Yog tias tus kav dej yuav tsis ntws mus rau qhov ntxeev, ntxuav nws los ntawm so nws ntawm daim txhuam cev ntub. Thaum twg tinned, so ntau dhau ntawm cov ntaub ntub dej. Koj tsis tas yuav tin qhov taub ua ntej txhua qhov sib koom ua ke, tab sis koj yuav tsum rov thim nws yog tias nws tau ploj mus thaum cov hlau tsis tau siv li ob peb feeb. cov chaw tsim khoom cov lus qhia cuam tshuam nrog tinning lub taub. Qhov taub ntawm cov hlau txuas yuav tsum yog xim ci ci. Yog tias nws yog xim dub thiab pitted, hloov nws nrog qhov tshiab.

Kauj Ruam 3: Ntxuav Qhov Nto

Rau qhov zoo soldering peb yuav tsum tau ntxuav cov nplaim rau qhov muag. Kuv siv cov dej cawv los txhuam nws kom huv.

Kauj Ruam 4: Soldering Smd Resistor

Tej yam zoo li resistors thiab capacitors feem ntau tuaj raws li cov duab plaub me me, qhov twg ob qhov xaus tsis sib xws yog cov neeg sib cuag. Txhawm rau muab cov tshuaj txhuam cov no, ntxiv cov tshuaj txhuam me me rau ib lub ncoo ntawm lub rooj tsavxwm. Siv tus tweezers los tuav cov khoom siv ntawm lub rooj tsavxwm, nrog rau ib kawg ntawm sab saum toj ntawm cov laug. Kov hlau mus rau tus pin ntawm lub ncoo nrog tus laug. Cov khoom siv yuav tsum ruaj khov rau ntawm lub rooj tsavxwm, thiab ob qho kawg yuav tsum tau ua kab nrog cov ntaub qhwv. Ntxiv me ntsis laug rau lwm qhov kawg, tsim "fillet" nruab nrab ntawm lub ncoo thiab cov khoom siv. Qhov zoo tshaj plaws, tsis muaj lub ntiaj teb loj loj ntawm cov laug thaum kawg. Yog tias muaj, siv cov tshuaj txhuam kom tshem tawm cov kab laug sab ntxiv. Thaum koj txoj haujlwm tiav lawm ntxuav nrog dej cawv.

Kauj ruam 5: Soldering Ics

Soldering ic nyuaj me ntsis dua resistor tab sis peb tuaj yeem ua nws. Ua ntej ntxuav qhov saum npoo ntxiv ntxiv qee qhov kev hloov pauv. Coj koj tus ic siv koj tus Tweezer los tso tus ic tom qab ntawd muab cov hmoov lead ntau rau ntawm tus pin no hu ua bridge.now koj tuaj yeem siv koj lub tswm ciab lossis lub twj tso kua mis kom tshem cov laug ntau dhau. Nco ntsoov tias tsis muaj tus choj tshwm sim. Ntxuav tus ic.
