Cov cuab yeej SMT nyob ntawm seb tus neeg siv khoom puas xav tau ib feem SMT cov khoom siv ntau lawm lossis nws tsis siv neeg SMT cov kab ntau lawm. Lub tshuab hluav taws xob ntau SMT feem ntau ib leeg yuav tsum tau siv lub tshuab rho ib nrab tshuab yob tshuab luam ntawv, muab tso rau siv tshuab, ua kom zoo nkauj, thiab txuas cov chaw nres tsheb; tag nrho SMT tsis zoo no feem ntau lawm kab yuav tsum siv lub tshuab chaw thau khoom thiab tsis siv neeg tin Paste tshuab luam ntawv, tso tshuab, reflow soldering, AOI tshuaj ntsuam tshuab, tsis siv neeg tshuab tsis siv neeg, tshuab txuas, thiab lwm yam.
Kuj tseem muaj qee cov kev pabcuam steel mesh, tin cub tawg, ua cua sov ua kom sov, hluav taws xob soldering hlau, ntxuav khoom siv thiab lwm yam.
Hauv qab no peb qhia luv luv txog SMT cov khoom tseem ceeb, thiab muab cov duab los piav qhia.
1. Phij Xauv Pas Tshuab Luam Ntawv
Cov tshuab luam ntawv muab tshuaj txhuam yog nyob ntawm thawj kab ntawm SMT cov kab ntau lawm thiab yog siv los luam cov plua plav hlaws lossis cov nplaum lo. Nws raug txia lub ham muab tshuaj lossis muab cov kua nplaum tso rau ntawm cov ntaub qhwv lossis cov haujlwm ua haujlwm ntawm cov ntawv luam tawm los npaj rau qhov kev tso kawm ntawm cheebtsam. Cov tshuab luam ntawv siv rau SMT yog ntxaib tau muab faib ua peb hom: tshuab luam ntawv, tshuab semi-automatic tshuab luam ntawv thiab siv lub tshuab ua haujlwm tsis siv neeg.
2.Qhov chaw tshuab
Lub tshuab tso chaw, tseem hu ua lub tshuab ntim khoom, yog nyob tom qab lub tshuab luam ntawv hauv SMT cov kab ntau lawm. Nws txoj haujlwm yog coj cov mount saum lub Cheebtsam tawm hauv cov pob thiab ua kom zoo nruab lawv rau ntawm txoj haujlwm ruaj khov ntawm cov ntawv luam tawm Circuit Court board. Qhov kev tso kawm muaj nuj nqi thiab ua haujlwm tau ntau lawm ntawm SMT cov kab ntau lawm nyob ntawm qhov ua haujlwm thiab qhov nrawm ntawm qhov chaw tso tshuab.
Lub tshuab tso khoom yog cov khoom siv thev naus laus zis ntau tshaj plaws, cov khoom siv khoom kim thiab cov khoom kim hauv SMT cov kab ntau lawm. Kev siv lub tshuab tso cav yog lub tshuab ua haujlwm siab, ceev-meej, cov cuab yeej siv dav thiab ntse heev ua ke nrog cov tshuab, hluav taws xob, pneumatic, kho qhov muag, khoos phis tawm, thiab cov thev naus laus zis. Hauv SMT cov kab ntau lawm, kev teeb tsa ntawm lub tshuab tso chaw yuav tsum txiav txim siab raws li hom thiab cov khoom lag luam tsim tawm.
3. Reflow welding tshuab
Reflow soldering tshuab, tseem hu ua reflow soldering tshuab, yog nyob tom qab lub chaw tso tshuab hauv SMT cov kab ntau lawm. Nws txoj haujlwm yog los muab cua kub ib puag ncig kom yaj cov cam muab tshuaj txhuam ua ntej faib rau cov ntawv luam tawm, kom cov pa saum npoo av sib xyaw thiab cov PCB ncoo tuaj yeem tso siab rau qhov sib xyaw nrog cov quav yaj nplaum txhuas.
Reflow soldering muaj cov kev ua haujlwm yooj yim, kev ua haujlwm siab, kev ua haujlwm zoo, kev sib thooj zoo, thiab kev txuag ham. Nws yog cov khoom siv hluav taws xob sib dhos khoom tsim thev naus laus zis tsim nyog rau kev siv tshuab ua lag luam. Nws tau dhau los ua lub ntsiab ntawm SMT Circuit board board tshuab thev naus laus zis.
4.Qhov tshuab soldering
Lub viav vias soldering tshuab yog cov khoom siv soldering uas siv cov voj voog nthwv dej ntawm molten solder hu mus rau qhov chaw soldering ntawm PCB nrog cov khoom sib xyaw, thiab ua kom tiav cov pab pawg soldering thaum tsiv ntawm qee qhov ceev. Nws yog tsuas yog siv nyob rau hauv tsoos dhau-qhov ntxig luam tawm Circuit board board cov txheej txheem thiab cov txheej txheem sib xyaw ua ke ntawm saum npoo los ua ke thiab dhau ntawm qhov ntxig cov khoom siv. Piv nrog rau vuam kev tuav, yoj soldering muaj qhov zoo ntawm kev tsim ntau lawm, kev ua haujlwm vuam zoo, thiab kev ntseeg siab.
5. Cov Khoom Siv Soj Ntsuam
Kev ua haujlwm ntawm cov cuab yeej tshuaj ntsuam yog tshuaj xyuas qhov sib dhos zoo thiab muaj txiaj ntsig ua qhov zoo ntawm cov PCB mounted. Cov cuab yeej siv suav nrog tsom iav, tsom tsom, lub ntsuas hluav taws xob tsis siv neeg lub tshuab ntsuas (AOI), ntsuas cov ntsuas online (ICT), X-RAY kev soj ntsuam xyuas, ua haujlwm tester, thiab lwm yam Raws li cov kev xav tau ntawm kev soj ntsuam, nws txoj haujlwm teeb tsa tom qab lub chaw nres tsheb coj los ntawm kab ntau lawm.
6. Kho cov khoom siv
Kev ua haujlwm ntawm cov khoom siv rov ua haujlwm yog los rov ua haujlwm thiab kho cov PCB uas tau tshawb pom qhov txhaum. Cov cuab yeej siv yog soldering hlau, chaw nres tsheb ua haujlwm, thiab lwm yam.
7. Cov khoom siv tu
Kev ua haujlwm ntawm cov cuab yeej kev tu yog tshem tawm cov tshuaj uas cuam tshuam rau kev ua haujlwm ntawm hluav taws xob ntawm cov chaw tsim hluav taws xob (PCB) lossis cov kuab seem xws li flux uas tsim kev puas tsuaj rau tib neeg lub cev. Yog tias tsis muaj cov tshuaj ntxuav dawb no, feem ntau tsis tsim nyog siv los ntxuav. Cov cuab yeej siv rau kev ntxuav tu yog lub tshuab ultrasonic tu thiab dej tshwj xeeb ntxuav kua. Lub chaw teeb tsa tsis hloov chaw, thiab nws tuaj yeem online lossis offline.
