Rau ntau lub tuam txhab khoom siv hluav taws xob me me thiab nruab nrab, outsourcing PCB thaj ua haujlwm yog ib txwm ua.Tab sis feem ntau hais lus, feem ntau cov chaw tsim khoom lag luam yuav tsis ua txhua yam rau koj, lossis lawv tsis tuaj yeem hloov cov neeg siv khoom los txhim kho qee yam, xws li pawg thawj coj saib thiab cov khoom lag luam hloov pauv, tsim qauv tsim, kev hloov pauv ib feem, thiab lwm yam.
Yog tias qhov kev yuav khoom lossis cov kws ua haujlwm ntawm lub tuam txhab tuaj yeem ua tau 8 yam hauv qab no zoo ua ntej muab cov kev xav tau thiab cov khoom tsim tawm mus rau PCB thaj ua haujlwm, feem ntau ntawm cov teeb meem tshwm sim tom qab kev tsim khoom thiab kev tsim khoom tuaj yeem zam tau.
1. Nrhiav qhov zoo tshaj plaws PCB loj rau koj tsim
Rau PCB raug tsim, cov laug cam me feem ntau txhais tau tias tus nqi qis, tab sis tus qauv tsim yuav xav tau ntau txheej sab hauv, uas yuav ua rau koj cov nqi nce ntxiv.Cov laug cam loj dua yuav yooj yim rau kev teeb tsa thiab yuav tsis xav tau cov teeb liab ntxiv, tab sis yuav kim dua rau kev tsim khoom.Ua ntej, koj yuav tsum xav txog yuav ua li cas xam qhov loj tshaj plaws haum yam tsis tau poob nta.
2. Qhia qhov loj ntawm cov khoom

Rau cov khoom tsis muaj zog, tus qauv loj ntawm 0603 yuav yog qhov kev xaiv zoo tshaj plaws rau tus nqi qis tshaj, uas kuj yog qhov loj me thiab muaj txiaj ntsig rau SMT sib dhos.0603 cov khoom siv kuj tseem yooj yim txav thiab kev pabcuam, thiab tsis txhob dhau los ua qhov cuam tshuam zoo li cov khoom siv me me.
Thaum Pinho tuaj yeem ua cov khoom siv 01005-qhov loj me, tsis yog txhua tus tuaj yeem ua tau, thiab cov khoom me me tsis tseem ceeb.
3. Tshawb xyuas cov khoom qub lossis tshiab heev
Cov khoom siv tsis tau pom tseeb yog qhov tsis siv lawm, uas yuav tsis txwv koj los ntawm kev ua PCBA, tab sis nws yuav tau daig hauv cov txheej txheem sib dhos.Niaj hnub no, txawm li cas los xij, qee qhov tshiab tsuas yog muaj nyob rau hauv ultra-me me wafer BGA lossis qhov me me QFN.Ua tib zoo saib ntawm koj tus qauv PCBA thiab xyuas kom tseeb tias koj tau hloov cov khoom siv tsis siv neeg nrog cov tshiab zoo dua.
Lwm daim ntawv yog yuav tsum nco ntsoov txog MLCCs koj siv, tam sim no lawv xav tau lub voj voog ntev.
Tam sim no peb muab cov neeg siv khoom nrog BOM tsom mus rau yav tom ntej, tiv tauj peb kom paub seb nws tuaj yeem pab koj li cas kom tsis txhob muaj kev pheej hmoo thiab txo cov peev nyiaj mus rau qhov loj tshaj plaws.
4. Xav txog lwm txoj hauv kev
Lwm txoj hauv kev yog ib lub tswv yim zoo, tshwj xeeb tshaj yog tias koj twb tau siv qee qhov khoom siv ib leeg.Ib qho khoom siv txhais tau tias koj poob kev tswj hwm tus nqi thiab lub sijhawm xa khoom, lwm txoj hauv kev yuav pab koj zam qhov ntawd.
5. Tsis txhob hnov qab dissipate cua sov thaum ua cov ntawv luam tawm hauv Circuit Court
Qhov loj heev thiab qhov me me tuaj yeem ua rau muaj teeb meem.Qhov loj dua ua me ntsis zoo li lub dab dej kub thiab tuaj yeem ua rau qhov me me.Tib yam tuaj yeem tshwm sim yog tias cov ntawv ci tooj liab sab hauv sib tshooj ntawm ib nrab ntawm ib qho me me tab sis tsis yog ib nrab.
6. Xyuas kom tseeb tias tus lej lej thiab cov cim polarity pom tau
Xyuas kom tseeb tias qhov twg silkscreen mus nrog qhov twg, thiab cov cim polarity tsis meej.Ua tib zoo saib xyuas tshwj xeeb rau cov khoom siv LED vim tias cov chaw tsim khoom qee zaum hloov cov cim polarity ntawm anode thiab cathode.Tsis tas li ntawd, khaws cov cim kom deb ntawm lub vias lossis ib qho pads.
7. Tshawb xyuas cov ntaub ntawv version
Yuav muaj ntau lub sijhawm luv luv ntawm PCB tsim lossis BOM, tsuas yog xyuas kom cov uas koj xa tuaj rau peb rau PCB fabrication yog qhov kev hloov kho zaum kawg.
8. Yog tias qee yam yuav raug muab
Thov xyuas kom meej tias koj tau sau npe thiab ntim lawv kom raug, suav nrog qhov ntau thiab tus lej sib raug.Cov ncauj lus kom ntxaws qhia yuav pab cov tuam txhab ua kom tiav cov khoom tsim thiab kev sib dhos ntawm cov ntawv luam tawm kom nrawm dua.
