SMT proofing yog ib tug kws PCBA ua chaw tsim tshuaj paus nrog nws tus kheej PCB Hoobkas thiab SMT thaj ua Hoobkas, uas yuav muab tau ib-nres PCBA Cov kev pab cuam xws li PCB pov thawj, kev yuav khoom, SMT thaj, dip plug-in, PCBA kuaj, tiav cov khoom sib dhos thiab lwm yam. Nov yog cov teeb meem xav tau kev saib xyuas hauv PCBA ua.

Cov teeb meem yuav tsum tau txiav txim siab hauv PCBA kev tsim khoom
1. Tsim ib lub rooj tsavxwm kis tau tus mob thiab muab tso rau hauv cov kab ntau lawm tsis siv neeg
Rau cov kab ntau lawm tsis siv neeg sib dhos, PCBA yuav tsum muaj peev xwm xa cov npoo thiab kho qhov muag pom cov cim, uas yog qhov yuav tsum tau ua ua ntej rau kev tsim khoom.
2. PCBA sib dhos txheej txheem tsim
Lub layout qauv ntawm cov khoom nyob rau hauv pem hauv ntej thiab nram qab ntawm PCBA txiav txim cov txheej txheem txheej txheem thiab txoj kev thaum lub sij hawm sib dhos.
3. Cov khoom tsim qauv tsim
Tsim txoj haujlwm, kev taw qhia thiab qhov sib txawv ntawm cov khoom ntawm lub rooj sib txoos nto. Cov txheej txheem ntawm cov khoom yog nyob ntawm txoj kev siv vuam siv. Txhua txoj kev vuam muaj cov kev cai tshwj xeeb rau txoj haujlwm layout, kev taw qhia thiab qhov sib nrug ntawm cov khoom.
4. los ua ke txheej txheem tsim
Rau kev tsim cov vuam dhau los ntawm tus nqi, los ntawm kev sib txuam tsim ntawm ncoo, tsis kam vuam thiab steel mesh, qhov ntau thiab ruaj khov-taw tes ruaj khov kev faib tawm ntawm cov tshuaj txhuam yog paub; Los ntawm kev tsim ntawm kev teeb tsa thiab xaim, qhov sib xyaw ua ke thiab kev sib koom ua ke ntawm tag nrho cov pob qij txha hauv ib pob tuaj yeem pom tau; Los ntawm qhov tsim nyog kev sib txuas tsim ntawm lub qhov mounting, 75% tin nkag tus nqi tuaj yeem ua tiav. Cov hom phiaj tsim qauv no yog qhov kawg los txhim kho qhov vuam tawm los.

Kev ceev faj rau PCBA vuam
1. Tus neeg zov lub tsev khaws khoom yuav tsum hnav cov hnab looj tes tiv thaiv zoo li qub thaum muab cov ntaub ntawv thiab kuaj IQC, thiab cov cuab yeej yuav tsum muaj kev ntseeg siab, thiab lub rooj ua haujlwm yuav tsum tau muab cov ntaub qhwv los tiv thaiv zoo li qub ua ntej.
2. Nyob rau hauv cov txheej txheem ntawm kev ua haujlwm, cov khoom siv ua haujlwm los tiv thaiv zoo li qub, thiab cov ntim khoom siv los tiv thaiv zoo li qub yog siv los tuav cov khoom thiab cov khoom ua tiav. Cov khoom siv vuam ntawm Lub Tsev Haujlwm tuaj yeem ua rau hauv av, thiab cov khoom siv hluav taws xob hluav taws xob yuav tsum yog hom anti-static. Txhua yam khoom siv yuav tsum raug kuaj ua ntej siv.
3. Thaum PCBA ua tiav los ntawm lub qhov cub, vim hais tias cov pins ntawm plug-in ntsiab yog ntxuav los ntawm tin flow, qee cov plug-in ntsiab yuav qaij tom qab vuam, uas ua rau lub cev lub cev dhau ntawm cov kab lo lo ntxhuav. Yog li ntawd, cov neeg ua haujlwm kho vuam tom qab lub qhov cub tawg yuav tsum tau kho kom raug.
4. Thaum PCBA vuam horn thiab roj teeb, nws yuav tsum tau muab sau tseg tias lub solder sib koom yuav tsum tsis txhob ntau dhau, uas yuav tsum tsis txhob ua rau luv luv Circuit Court los yog poob ntawm ib puag ncig cov khoom.
5. PCBA substrates yuav tsum muab tso rau kom huv si, thiab cov phaj liab qab tsis tuaj yeem muab tso ncaj qha. Yog xav tau stacking, nws yuav tsum tau ntim rau hauv cov hnab electrostatic.

Kev ceev faj rau PCBA tiav cov khoom sib dhos
1. Lub tshuab tag nrho tsis muaj plhaub siv lub hnab ntim khoom tiv thaiv zoo li qub
Kev tshuaj xyuas cov cuab yeej tiv thaiv zoo li qub, kev teeb tsa thiab cov khoom siv tsis tu ncua kom ntseeg tau tias lub xeev ua haujlwm ua tau raws li qhov yuav tsum tau ua.
2. Thaum sib dhos cov khoom tiav, ua raws li cov txheej txheem hauv qab no
Warehouse → ntau lawm kab → ntau lawm kab upgrade software → sib dhos rau hauv ib lub tshuab ua kom tiav → QC xeem → sau IMEI tooj → QA tag nrho kev soj ntsuam → rov qab Hoobkas nqis → warehousing; Lub software yuav tsum tau upgraded ua ntej los ua ke. Nws tsis tuaj yeem sib sau ua ke rau hauv lub tshuab tiav thiab tom qab ntawd hloov kho dua tshiab. Nws yuav tsis raug kho dua tshiab vim qhov tsis raug vuam, luv Circuit Court, teeb meem kev ua haujlwm, thiab lwm yam, ua rau kev txiav txim siab tsis zoo ntawm PCBA.

Cov saum toj no yog dab tsi xav tau kev saib xyuas hauv PCBA ua? PCBA kev ua haujlwm yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus, Kuv vam tias nws tuaj yeem pab koj.
