Hais txog thev naus laus zis, cov txheej txheem ntawm PCBa tuaj yeem muab faib ua plaub txuas, uas yog: SMT Chip ua → PCBA sim ua ke.
1. SMT Ntot Ua Txuas Txuas
Hauv SMT MINE ua haujlwm ua haujlwm, cov cheebtsam yuav sib phim thiab yuav raws li cov npe Bom Matching muab los ntawm cov qhua tuaj noj mov muab los ntawm cov qhua tuaj noj mov muab los ntawm cov qhua tuaj noj mov muab los ntawm cov qhua tuaj noj mov muab los ntawm cov qhua tuaj noj mov, thiab cov phiaj xwm PMC ntawm cov khoom yuav raug lees paub. Tom qab npaj ua haujlwm tiav, SMT programming pib, laser stencil yog ua raws li cov txheej txheem SMT, thiab Sold muab luam tawm yog ua.
Nrog SMT tso chaw siv lub tshuab, cov khoom siv tau mounted mus rau Circuit Court Board thiab cov hauv-Line AOI tsis siv neeg soj ntsuam yog ua yog tsim nyog. Tom qab sim, teeb tsa lub zoo meej reflow cub kub profile kom tso cai rau pawg thawj coj ntws los ntawm kev xav txog kev xav.
Tom qab cov ntaub ntawv kuaj IPQCS tsim nyog, cov ntaub ntawv pov dip los ua kom dhau cov khoom siv hluav taws xob thiab tom qab ntawd ntws los ntawm nthwv dej rau soldering. Qhov no yog ua raws li los ntawm cov txheej txheem tom qab tsim nyog.
Tom qab cov txheej txheem saum toj no tiav, QA yuav ua cov tshuaj ntsuam xyuas kom paub tseeb tias cov khoom lag luam zoo.
Thib Ob, DIP Plug-in Ua Txuas
Cov txheej txheem ntawm DIP Plug-in Ua → yoj soldering → shearing ko taw → tom qab welding → kev tshuaj xyuas zoo
3. PCBA xeem
PCBA kev sim siab tshaj plaws feem ntau cov qauv PCBA yuav tsum ua raws PCBA xeem cov qauv ntawm cov Circuit Court Board raws li kev xeem cov neeg yuav khoom ntiag tug (phiaj xwm xeem).
PCBA kuaj kuj suav nrog 5 daim ntawv loj: ICT kuaj, FT sim sim, kev sim rog, thiab kuaj ntawm cov chaw hnyav.
Plaub, cov khoom lag luam tiav ua ke
Tus kws pab pawg PCBa uas yog OK rau kev kuaj yog sib sau ua ke rau lub tsev nyob, thiab tom qab ntawd sim, thiab thaum kawg nws tau npaj yuav khoom xa tuaj.
PCBA ntau lawm yog qhov txuas txuas rau qhov txuas, txhua qhov txuas muaj teeb meem yuav muaj qhov cuam tshuam loj heev rau ntawm qhov zoo tshaj plaws, thiab txhua tus txheej txheem yuav tsum tau tswj hwm txhua yam.
Qhov saum toj no yog hais txog plaub txuas tseem ceeb ntawm PCBA cov txheej txheem muaj ntau cov txheej txheem sib txuas me me los pab kom cov khoom siv tsis zoo. Qhov no tseem muaj kev sib xws ntawm Jetobang - cov neeg siv khoom xaj los ntawm kev txiav txim rau cov zaub mov xa tuaj, tag nrho cov txheej txheem ua raws li cov neeg ua haujlwm pabcuam thiab kev ua tau zoo tuaj yeem ua rau koj xav tias nws yooj yim.
