Plaub Yam Yuav Tsum Tau Ceeb Tseg Rau Hauv PCBA Patch Processing
Jun 10, 2020
1. SMT thaj sib dhos
Kev luam tawm ntawm cov tshuaj txhuam cov roj hauv cov SMT qhov kev tso kawm thiab cov kab ke ua haujlwm zoo kom paub meej ntawm reflow soldering kub tswj yog cov node tseem ceeb hauv PCBA kev tsim khoom. Nyob rau tib lub sijhawm, rau kev luam ntawm high-precision Circuit Board nrog cov txheej txheem tshwj xeeb thiab cov txheej txheem, laser stencils yuav tsum tau siv raws li cov xwm txheej tshwj xeeb kom tau raws li qhov yuav tsum ua kom tau zoo dua thiab xav tau ntawm cov laug cam Circuit Court. Raws li cov PCB tsim kev lag luam thiab cov yam ntxwv ntawm cov neeg siv khoom, qee qhov yuav tsum tau nce qib U-puab lossis txo cov hlau mesh qhov. Cov hlau mesh xav tau kev ua raws li qhov yuav tsum ua ntawm PCBA ua kev siv tshuab.
Ntawm lawv, kev tswj qhov kub thiab txias qhov tseeb ntawm reflow soldering rauv yog ib qho tseem ceeb heev rau cov muab tshuaj txhuam cov tshuab ua kom ntub thiab cov quav hlau, thiab tuaj yeem hloov kho raws li cov kev ua haujlwm SOP li qub. Txhawm rau txo qis qhov tsis zoo ntawm PCBA thaj ua rau hauv SMT qhov txuas. Ntxiv rau, kev siv nruj ntawm kev xeem AOI tuaj yeem txo ntau qhov tsis xws tshwm sim los ntawm tib neeg yam.
2 .IP ntsaws tom qab xaim
DIP plug-in post soldering yog cov txheej txheem tseem ceeb tshaj plaws hauv kev ua theem ntawm pawg thawj coj saib, thiab nws tseem yog tus txheej txheem kawg. Hauv cov txheej txheem tom qab txuas ntawm DIP ntsaws, qhov kev txiav txim siab ntawm lub tshuab ua kom sov rau cov tshuab muaj yoj yog qhov tseem ceeb heev. Yuav ua li cas siv hluav taws xob ua kom zoo dua ua kom zoo dua cov tawm thiab txo cov teeb meem soldering xws li cov ntawv sib txuas, tsis tshua muaj tin thiab tin tsis txaus, thiab raws li qhov sib txawv ntawm cov neeg yuav khoom' cov khoom lag luam, pcba ua cov nroj tsuag yuav tsum txuas ntxiv cov kev sib txuas ua ke hauv kev coj ua thiab paub txog kev txhim kho ntawm cov thev naus laus zis hauv cov txheej txheem kev tsub zuj zuj ntawm kev paub.
3. Kuaj thiab qhov kev hlawv khoom
Daim ntawv qhia kev tsim khoom lag luam yuav tsum yog qhov ntsuas kev soj ntsuam ua ntej tag nrho ntau lawm tom qab tau txais tus neeg muas zaub' s daim ntawv cog lus ntau lawm.
Hauv daim ntawv tshaj tawm DFM dhau los, peb tuaj yeem muab qee cov lus qhia rau cov qhua tuaj noj mov ua ntej cov txheej txheem PCB. Piv txwv, teeb tsa qee qhov kev ntsuas tseem ceeb ntawm PCB txhawm rau ua tiav qhov kev ntsuas PCB soldering thiab kev ntsuas tseem ceeb ntawm kev txuas ntxiv thiab txuas txuas ntawm Circuit Court tom qab ua tiav PCBA. Thaum muaj kev tso cai, koj tuaj yeem sib txuas lus nrog cov qhua tuaj noj mov los muab cov kev pabcuam tom qab-kawg, thiab tom qab ntawd hlawv cov haujlwm PCBA rau hauv cov tub ntxhais tseem ceeb IC los ntawm lub tshuab hlawv. Nyob rau hauv txoj kev no, lub rooj tsav xwm Circuit Court tuaj yeem raug sim hauv qhov yooj yim los ntawm kev ua kov, yog li txhawm rau kuaj thiab saib xyuas kev ncaj ncees ntawm tag nrho PCBA, thiab nrhiav cov khoom tsis raug raws sijhawm.
4. PCBA raug kuaj
Ib qho ntxiv, ntau tus neeg muas zaub nrhiav PCBA ua kev los ntawm kev qhia tsheb ciav hlau kuj tseem muaj rau PCBA qhov kev xeem rov qab. Cov ntsiab lus ntawm cov ntawv ntsuas no feem ntau suav nrog ICT (kev ntsuam xyuas Circuit Court), FCT (kuaj mob ua haujlwm), hlawv ntsuas (kev laus dhau los), ntsuas kub thiab av noo, ntsuas kev xeem, thiab lwm yam.
