Ua kom lub ntsej muag ntawm koj cov khoom ua haujlwm huv si thaum koj tab tom sim siv lub tshuab ziab khaub ncaws yog qhov tseem ceeb ib yam li khaws daim ntawv tso cai tso rau hauv koj lub tsheb. Thiab kuv tsis yog qhov tsawg tshaj plaws sarcastic, koj daim nqi tam sim no yuav nce mus rau qhov ua tsis tau zoo. Yog tias koj tsis siv flux los ntxuav koj cov tawv nqaij qhov muag yuav tawm ua ntej koj paub nws.
Dhau li, cov hlau kub zoo li tsim cov oxides thaum nws los tiv nrog huab cua. Qhov ntawd ua rau tus neeg muag khoom ua tsis tiav ntau lub sijhawm. Niaj hnub no muaj ob peb yam sib txawv ntawm cov laug nyob ntawd. Wb tham txog lawv.
Hauv kab ntawv no peb yuav npog:
Hom Soldering Flux
Soldering fluxes txawv ntau yam ntawm lawv qhov ua tau zoo, lub zog, cuam tshuam rau soldering zoo, kev ntseeg tau, thiab lwm yam. Vim li no, koj tsis tuaj yeem siv ib qho twg ntws tus neeg sawv cev rau cov xov hlau los yog cov khoom siv hluav taws xob. Raws li lawv cov kev ua haujlwm flux, soldering flux tseem ceeb poob rau hauv cov pawg hauv qab no:
Rosin Pluas
muaj ntau hom flux rau hluav taws xob soldering, rosin flux yog ib qho ntawm lawv nyiam tshaj plaws. Lub hauv paus tseem ceeb hauv rosin flux yog rosin uas tau muab rho tawm los ntawm kev ua kom huv pinesap. Tsis tas li ntawd, nws muaj cov khoom xyaw ua kom muaj zog abietic acid nrog rau ob peb cov kua qaub ntuj. Feem ntau cov paj ntoo rosin muaj cov neeg ua haujlwm hauv lawv uas ua rau cov dej ntws mus rau deoxidize thiab ntxuav cov chaw ua haujlwm. Hom no tuaj yeem muab faib ua peb hom qis:
Rosin (R) Flux
Qhov rosin (R) flux no tsuas yog tsim los ntawm rosin thiab tsawg kawg ua haujlwm ntawm peb hom. Nws feem ntau yog siv rau kev xaim tooj liab tooj liab, PCBs, thiab lwm yam siv rau tes siv. Feem ntau, nws tau siv rau ntawm qhov chaw uas tau ntxuav tas nrog qhov tsawg kawg ntawm oxidation. Qhov zoo tshaj plaws ntawm nws yog nws tsis tso tseg qhov seem tom qab.
Rosin Mildly Active (RMA)
Rosin ua kom lub cev ua haujlwm me me muaj cov neeg ua haujlwm txaus los ntxuav qhov chaw qias neeg. Txawm li cas los xij, cov khoom lag luam no tau tso tseg ntau dua li lwm qhov dej ntws zoo ib yam. Yog li, tom qab siv, koj yuav tsum ntxuav qhov saum npoo nrog cov tshuaj ntxhua khaub ncaws kom tsis txhob muaj kev puas tsuaj rau hauv Circuit lossis cov khoom.
Rosin Activated (RA)
Rosin qhib tau yog qhov nquag tshaj plaws ntawm peb hom rosin fluxes. Nws ntxuav qhov zoo tshaj plaws thiab muab cov tshuaj txhuam zoo heev. Qhov no ua rau lawv zoo tshaj plaws rau kev tu tawv nqaij kom huv nrog ntau cov oxides tam sim no. Ntawm qhov ntxeev sab, hom no tsis tshua siv vim nws zoo li tso ntau qhov seem tom qab.
Dej Soluble Flux lossis Organic Acid Flux
Hom no feem ntau muaj cov organic acids tsis muaj zog thiab yaj tau yooj yim hauv dej thiab isopropyl cawv. Yog li, koj tuaj yeem tshem cov dej ntws tawm tsuas yog siv cov dej tsis tu ncua. Tab sis koj yuav tsum tau saib xyuas tias cov khoom tsis ntub.
Ib qho ntxiv, hom no muaj lub zog muaj zog ntau dua li cov dej ntws los ntawm rosin. Vim li no, lawv yog txoj hauv kev nrawm dua ntawm kev tshem cov oxides saum npoo av. Txawm li cas los xij, koj yuav xav tau kev tiv thaiv ntxiv thaum ntxuav PCB kom tsis txhob kis kab mob. Tsis tas li ntawd, tom qab siv cov khoom siv tas lawm, yuav tsum muab cov khoom seem tso rau hauv qhov seem.
Inorganic Acid Flux
Inorganic acid fluxes yog txhais tau rau qhov kub thiab txias soldering uas nyuaj rau sib cog. Cov no yog cov xeb ntau dua lossis muaj zog dua li cov organic fluxes. Dhau li, lawv tau siv rau cov hlau muaj zog thiab pab tshem tawm ntau cov oxides los ntawm cov hlau hnyav oxidized. Tab sis, cov no tsis zoo tshaj rau kev sib dhos hluav taws xob.
Tsis-Ntxuav Flux
Rau hom flux no, tsis tas yuav tsum tau tu tom qab siv tas. Nws tau qhia tshwj xeeb uas tsim los kom ua tau zoo me ntsis. Li no txawm hais tias muaj qhov seem me me tshuav, nws yuav tsis ua kev puas tsuaj rau cov khoom lossis cov laug cam. Vim li no, cov no zoo tagnrho rau kev siv lub tshuab ua haujlwm tsis zoo, yoj yoj, thiab nto PCBs.
Phau Ntawv Qhia Yooj Yim | Yuav Ua Li Cas Siv Flux rau Soldering
Raws li koj tuaj yeem pom muaj ntau ntau hom flux rau cov khoom siv hluav taws xob muaj nyob rau hauv ntau yam textures zoo li kua lossis muab tshuaj txhuam. Tsis tas li, rau cov txheej txheem sib txawv sib txawv flux tau thov sib txawv. Yog li ntawd, kom koj yooj yim dua thiab kom tsis txhob muaj kev ntxhov siab, ntawm no peb mus rau cov lus qhia ib qib-ib-qib ntawm kev siv cov tshuaj txhuam hniav.
Xaiv Qhov Zoo Tshaj Plaws thiab Ntxuav Qhov Nto
Thaum xub thawj, xaiv qhov tsim nyog rau koj txoj haujlwm soldering los ntawm peb cov npe ntawm ntau hom kev sib txuas fluxes. Tom ntej no, koj yuav tsum ntxuav cov hlau nto kom nws tsis muaj plua plav, hmoov av, lossis oxidation ntau dhau.
Npog Cheeb Tsam nrog Flux
Tom qab ntawd, koj yuav tsum tau thov ib txheej txheej ntawm cov dej uas tau xaiv mus rau saum qhov chaw uas koj yuav tau siv lub tshuab ziab khaub ncaws. Nco ntsoov tias koj yuav tsum npog tag nrho thaj chaw. Hauv theem no, koj yuav tsum tsis txhob siv cua sov.
Thov cua sov nrog Cov Hluav Taws Xob
Tom ntej no, pib cov hlau kom lub taub hau kub txaus kom yaj cov dej ntws nrog kev sib cuag. Muab cov hlau tso rau saum cov flux thiab tso cai rau nws yaj cov dej ntws mus ua kua. Qhov no tsis tsuas yog yuav pab tshem tawm cov txheej txheej oxide tam sim no, tab sis tseem yuav tiv thaiv kev oxidization yav tom ntej kom txog thaum cov dej ntws tawm. Tam sim no, koj tuaj yeem pib txheej txheem txheej txheem.
Soldering Wire nrog Soldering Flux
Siv cov khoom siv hluav taws xob txuas thaum siv cov xov hlau lossis cov txuas sib txuas muaj ob peb qhov sib txawv los ntawm cov txheej txheem dav dav peb tau piav qhia ua ntej. Raws li cov no yog qhov muag heev, ob peb qhov kev hloov pauv yuav ua rau cov xov hlau puas. Qhov no yog vim li cas, ua ntej siv cov kab hluav taws xob ntawm cov xov hlau, xyuas kom tseeb tias koj tau ua cov txheej txheem raug.
Xaiv Txoj Cai Flux
Raws li cov xov hlau feem ntau tsis muaj zog thiab nyias, siv ib yam dab tsi uas xeb heev tuaj yeem ua rau koj lub Circuit puas. Yog li, ntau tus kws tshaj lij tawm tswv yim xaiv cov rosin-based flux rau soldering vim nws yog qhov tsawg tshaj plaws corrosive.
Ntxuav thiab Intertwine Cov Xov
Feem ntau ua kom ntseeg tau tias txhua lub xaim huv. Tam sim no, ntswj qhov kawg ntawm txhua lub xov hlau ua ke. Khaws cov xov hlau hla thiab ib puag ncig kom txog thaum koj tsis tuaj yeem pom ib qho twg xaus. Thiab yog tias koj xav tso cov cua sov-dab dej hla koj cov laug, ua qhov no ua ntej ntswj cov xov hlau. Xyuas kom tseeb tias cov tubing me me thiab nqaim nruj rau cov xov hlau.
Muab Soldering Flux rau ntawm Cov Xov Tooj
Txhawm rau tiv thaiv cov xov hlau, siv koj cov ntiv tes lossis txhuam me me los daus me me ntawm cov dej ntws thiab kis lawv hla thaj chaw. Flux yuav tsum npog tag nrho cov xov hlau. Tsis tas yuav hais, koj yuav tsum so ntau dhau ua ntej pib ua kom sov.
Qhuav lub Flux nrog Soldering Iron
Ua kom sov cov hlau tam sim no thiab thaum nws kub, nias cov hlau mus rau ib sab ntawm cov xov hlau. Ua cov txheej txheem no txuas ntxiv mus kom txog thaum cov dej ntws tau yaj tag thiab pib ua npuas. Koj tuaj yeem tso me me ntawm cov laug rau ntawm lub taub hlau thaum nias nws mus rau xaim kom nrawm hloov pauv cua sov.
Siv Solder rau hauv Cov Xov
Thaum cov hlau raug nias tawm tsam cov xov hlau ntawm sab hauv qab, siv qee qhov solder rau lwm sab ntawm cov xov hlau. Cov laug yuav yaj tam sim yog tias cov hlau kub txaus. Nco ntsoov tias koj yuav muab cov laug txuas txaus los npog qhov kev sib txuas tag nrho.
Cia Tus Tub Rog Harden
Tam sim no coj cov hlau txuas mus thiab ua siab ntev rau lub lauj kaub kom txias. Raws li lawv txias koj tuaj yeem pom lawv tawv. Thaum cov laug tau teeb tsa, saib rau ib qho xaim raug. Yog tias muaj ib qho, pub qee qhov txuas ntxiv rau nws thiab cia lawv tawv.
xaus
Soldering kos duab yog qhov yooj yim heev, tab sis qhov ua yuam kev me me tuaj yeem yog txoj hauv kev los tsim kev sib raug zoo. Yog li, nws yog qhov tsim nyog kawg kom paub txog kev siv kom raug ntawm kev siv tshuaj yaj yeeb. Txawm hais tias koj yog tus pib lossis tsis yog tus kws tshaj lij, vam tias, peb cov lus qhia ntxaws tau pab koj txaus kom nkag siab txhua yam tsim nyog ntawm kev siv nws.
Nco ntsoov tias cov tshuaj txhuam hniav tuaj yeem ua xeb thiab tuaj yeem ua rau koj cov tawv nqaij puas tsuaj yog tias nws ua kua lossis ua kom sov. Tab sis koj tsis tas yuav txhawj xeeb yog tias nws muaj cov ntxhiab tsw qab. Rau kev nyab xeeb ntxiv, siv cov hnab looj tes tawv tiv tshav kub thaum ua haujlwm.
Kuv yog Joost Nusselder, tus tsim ntawm Tools Doctor, cov ntsiab lus lag luam, thiab txiv. Kuv nyiam sim cov cuab yeej tshiab, thiab ua ke nrog kuv pab neeg kuv tau tsim cov ntawv blog tob txij li xyoo 2016 los pab cov neeg nyeem siab ncaj nrog cov cuab yeej & cov lus qhia ua khoom siv.
