PCBA hais txog cov txheej txheem mounting, inserting thiab soldering liab qab PCB Cheebtsam.Cov txheej txheem tsim khoom ntawm PCBA yuav tsum mus dhau ntawm cov txheej txheem ua kom tiav cov khoom.Tam sim no, PCBFuture yuav qhia txog ntau yam txheej txheem ntawm PCBA ntau lawm.
PCBA txheej txheem ntau lawm tuaj yeem muab faib ua ntau yam txheej txheem, SMT thaj ua haujlwm → DIP plug-in processing → PCBA kuaj → tiav cov khoom sib dhos.
Ua ntej, SMT thaj ua haujlwm txuas
Cov txheej txheem ntawm SMT nti ua yog: solder paste mixing → solder paste printing → SPI → mounting → reflow soldering → AOI → rework
1, solder paste mixing
Tom qab solder paste raug tshem tawm ntawm lub tub yees thiab thawed, nws yog nplawm los ntawm tes los yog tshuab kom haum rau luam ntawv thiab soldering.
2, solder paste luam ntawv
Muab cov tshuaj pleev xim rau ntawm daim stencil, thiab siv cov squeegee los luam cov xim pleev xim rau ntawm PCB pads.
3, SIB
SPI yog cov khoom siv tshuaj nplaum tuab, uas tuaj yeem kuaj xyuas cov luam ntawv ntawm cov tshuaj txhuam thiab tswj xyuas cov nyhuv luam tawm ntawm cov tshuaj txhuam.
4. Mounting
SMD Cheebtsam tau muab tso rau ntawm lub feeder, thiab lub tshuab tso rau lub taub hau kom raug tso cov khoom ntawm lub feeder ntawm PCB pads los ntawm kev txheeb xyuas.
5. Reflow soldering
Dhau lub mounted PCB board los ntawm reflow soldering, thiab cov muab tshuaj txhuam zoo li solder paste yog rhuab rau cov kua los ntawm qhov kub siab nyob rau hauv, thiab thaum kawg txias thiab solidified kom tiav cov soldering.
6. UAS
AOI yog qhov kev tshuaj xyuas tsis siv neeg kho qhov muag, uas tuaj yeem kuaj xyuas qhov cuam tshuam ntawm PCB board los ntawm kev tshuaj xyuas, thiab kuaj xyuas qhov tsis xws ntawm lub rooj tsavxwm.
7. kho
Kho qhov tsis xws luag pom los ntawm AOI lossis kev tshuaj xyuas phau ntawv.
Qhov thib ob, DIP plug-in processing txuas
Cov txheej txheem ntawm DIP plug-in processing yog: plug-in → yoj soldering → txiav ko taw → tom qab vuam txheej txheem → ntxuav board → kev soj ntsuam zoo
1, plug-nyob rau hauv
Ua cov pins ntawm cov khoom siv plug-in thiab ntxig rau ntawm lub rooj tsavxwm PCB
2, yoj soldering
Lub board inserted yog raug rau yoj soldering.Nyob rau hauv cov txheej txheem no, cov kua tin yuav raug txau rau ntawm lub rooj tsavxwm PCB, thiab thaum kawg txias kom tiav cov soldering.
3, txiav ko taw
Cov pins ntawm lub rooj tsavxwm soldered ntev dhau lawm thiab yuav tsum tau muab txiav.
4, tom qab vuam txheej txheem
Siv hluav taws xob soldering hlau los manually solder cov khoom.
5. Ntxuav lub phaj
Tom qab yoj soldering, lub rooj tsavxwm yuav qias neeg, yog li koj yuav tsum tau siv cov dej ntxuav thiab ntxuav lub tank los ntxuav nws, lossis siv lub tshuab los ntxuav.
6, kev soj ntsuam zoo
Tshawb xyuas PCB pawg thawj coj saib, cov khoom tsis tsim nyog yuav tsum tau kho, thiab tsuas yog cov khoom tsim nyog tuaj yeem nkag mus rau cov txheej txheem tom ntej.
Thib peb, PCBA xeem
PCBA xeem tuaj yeem muab faib ua ICT test, FCT test, aging test, vibration test, etc.
Kev xeem PCBA yog qhov kev xeem loj.Raws li cov khoom sib txawv thiab cov neeg siv khoom sib txawv, cov kev sim siv tau sib txawv.
Plaub, tiav cov khoom sib dhos
Lub rooj tsavxwm PCBA kuaj tau sib sau ua ke rau lub plhaub, thiab tom qab ntawd sim, thiab thaum kawg nws tuaj yeem xa tuaj.
PCBA ntau lawm yog ib qhov txuas tom qab lwm qhov.Ib qho teeb meem hauv ib qho kev sib txuas yuav muaj kev cuam tshuam loj heev rau tag nrho qhov zoo, thiab kev tswj hwm nruj ntawm txhua txoj kev yuav tsum tau ua.
