Kev ua cov txheej txheem PCBA koom nrog ntau txoj kev sib txuas, thiab nws yog qhov yuav tsum tau los tswj qhov zoo ntawm txhua qhov txuas los tsim cov khoom zoo. Lub PCBA dav dav yog li ntawm: PCB Circuit board board kev tsim khoom, kev tiv thaiv cov khoom siv thiab kev soj ntsuam, SMT thaj ua, ntsaws cov txheej txheem, Txheej txheem ntawm cov txheej txheem xws li kev hlawv cov txheej txheem, kuaj, laus, thiab lwm yam Hauv qab no peb ua tib zoo piav qhia cov ntsiab lus uas xav tau xyuam xim rau hauv txhua qhov txuas.
1. Kev lag luam PCB Circuit Court board
Tom qab tau txais PCBA qhov kev txiav txim, txheeb xyuas cov ntawv Gerber, ua tib zoo saib xyuas kev sib raug zoo ntawm PCB lub qhov qhov sib txawv thiab cov kabmob muaj peev xwm ntawm lub rooj tsavxwm, tsis txhob ua rau khoov lossis tawg, thiab seb cov xov hluav taws xob txiav txim siab txog qee yam tseem ceeb xws li lub teeb liab loj cuam tshuam. thiab impedance.
2. Lub Cheebtsam saib xyuas kev lag luam thiab tshuaj ntsuam
Kev ua kom tau ntawm cov khoom siv yuav tsum tau tswj hwm txoj kev nruj, thiab nws yog qhov yuav tsum tau khaws cov khoom lag luam los ntawm cov tub luam loj thiab cov thawj tuam txhab, thiab 100% zam kev siv cov khoom siv thib ob thiab cov khoom cuav. Ntxiv rau, teeb tsa tshwj xeeb cov khoom lag luam soj ntsuam kev soj ntsuam, nruj saib xyuas cov khoom hauv qab no kom ntseeg tau tias cov Cheebtsam tsis txhaum.
PCB: ntsuas kub ntawm reflow soldering rauv taws, kev txwv tsis pub ya xov hlau, seb lub qhov yog thaiv lossis cov kua xau, seb lub rooj tsavxwm saum npoo yog khoov, thiab lwm yam;
IC: Txheeb xyuas seb qhov xov kab silk puas tau ua tiav nrog BOM, thiab khaws nws ntawm qhov kub thiab txias thiab av noo tas li;
Lwm cov khoom siv thoob plaws: kos lub vijtsam silk, tsos, lub zog ntsuas, thiab lwm yam Cov khoom ntsuas tshuaj xyuas tau ua raws li tus txheej txheem kuaj random, thiab qhov feem ntau yog 1-3%.
3. SMT los ua ke ua
Solder paste printing thiab reflow soldering rauv kub tswj yog qhov ntsiab lus tseem ceeb. Nws yog ib qho tseem ceeb heev rau kev siv laser stencil nrog cov khoom zoo thiab ua tau raws li cov txheej txheem xav tau. Raws li cov kev xav tau ntawm PCB, qee qhov yuav tsum tau nce lossis tsawg dua ntawm cov hlau mesh, lossis siv U-zoo li lub qhov, raws li cov txheej txheem yuav tsum ua cov hlau mesh. Lub tshuab ua kom sov sov thiab kev tswj ceev ntawm reflow soldering yog ib qho tseem ceeb rau cov yob muab tshuaj txhuam thiab ua kom txoj kev ntseeg siab zoo, thiab tuaj yeem tswj tau raws li kev ua haujlwm SOP cov lus qhia. Ntxiv rau, kev tshuaj ntsuam AOI yuav tsum tau ua kom nruj kom txo qis cov kev phem uas tshwm sim los ntawm tib neeg yam.
4. DIP plug-in processing
Hauv cov txheej txheem plug-in, tus qauv tsim pwm tsim rau yoj soldering yog lub ntsiab lus tseem ceeb. Kev siv lub pwm tuaj yeem ua kom qhov tshwm sim ntau ntawm kev muab cov khoom lag luam zoo tom qab lub tshuab ua kom sov, uas yog tus txheej txheem uas PE engineers yuav tsum tau xyaum ua tas li thiab suav cov kev paub.
5. Qhov kev hlawv khoom
Hauv daim ntawv tshaj tawm DFM dhau los, cov qhua tuaj yeem hais qhia kom teeb tsa qee qhov kev ntsuas ntawm PCB (Cov Ntsiab Lus Ntsuas), lub hom phiaj yog txhawm rau txhawm rau ntsuas PCB thiab PCBA txuas ntxiv tom qab muag tag nrho cov khoom. Yog tias koj muaj cov xwm txheej, koj tuaj yeem thov cov neeg siv khoom lag luam los muab qhov program, hlawv cov program rau hauv qhov kev tswj hwm loj IC los ntawm lub tshuab hlawv (xws li ST-LINK, J-LINK, thiab lwm yam), koj tuaj yeem sim kuaj ntau qhov kev sim. cov kev nqis tes ua los ntawm Kev Hloov Hloov pauv los ntsuas qhov kev ua haujlwm ntawm tag nrho PCBA.
6. PCBA board xeem
Rau cov kev txiav txim siab nrog PCBA qhov yuav tsum tau xeem, cov ntsiab lus tseem ceeb suav nrog ICT (Hauv Kev Ntsuas Hluav Taws Xob), FCT (Kev Ntsuam Xyuas Kev Ntsuas), Kev Ntsuas Hluav Taws Xob (Kev Ntsuas Kev laus), ntsuas kub thiab av noo, ntsuas xeem, thiab lwm yam, raws li cov neeg siv' s kev npaj ua haujlwm npaj thiab sau ua ke cov ntaub ntawv tshaj tawm.
