Kev ua cov PCBA koom nrog ntau cov txuas, yog li peb yuav tsum tswj hwm qhov zoo ntawm txhua qhov txuas los tsim cov khoom lag luam zoo. Lub PCBA dav dav yog cov txheej txheem ntau yam, xws li PCB pawg thawj coj saib kev tsim khoom, kev tiv thaiv cov khoom siv thiab kev soj ntsuam, SMT SMT nti ua, ntsaws ua cov txheej txheem, qhov kev zov me nyuam tua hluav taws, kuaj, laus thiab lwm yam. Tom ntej no, peb yuav piav qhia ntxiv ntawm cov ntsiab lus xav tau saib xyuas hauv txhua qhov txuas.
1. Kev lag luam PCB
Tom qab tau txais PCBA qhov kev txiav txim, txheeb xyuas cov ntaub ntawv Gerber, saib xyuas kev sib raug zoo ntawm PCB lub qhov qhov sib txawv thiab lub rooj tsav xwm muaj peev xwm, tsis txhob ua rau khoov lossis pob txha tawg, thiab seb lub teeb liab loj cuam tshuam, cuam tshuam thiab lwm yam tseem ceeb tau txiav txim siab hauv xaim.
2. Kev yuav khoom thiab tshuaj xyuas cov txheej txheem
Peb yuav tsum nruj tswj hwm txoj kev ntawm kev yuav cov khoom siv. Peb yuav tsum nqa cov khoom xa los ntawm cov tub luam loj thiab cov thawj tuam txhab, thiab zam cov khoom siv thib ob thiab cov khoom cuav 100%. Tsis tas li ntawd, ib qho tshwj xeeb rau kev soj ntsuam tom qab tau tsim los ua nruj me ntsis tshawb xyuas cov khoom hauv qab no kom ntseeg tau tias tsis muaj kev txhaum ntawm cov Cheebtsam.
PCB: reflow cub ntsuas kub, tsis muaj lub xov hlau ya, dhau ntawm lub qhov thaiv lossis cov dej xau, lub rooj tsavxwm nto khoov, thiab lwm yam;
IC: xyuas seb puas yog silk screen luam tawm thiab BOM yog ua tiav zoo ib yam, thiab ua cov kev ntsuas kub tsis tu ncua thiab cov av noo;
Lwm cov ntaub ntawv siv dav: kev tshuaj ntsuam luam ntawv, tsos, ntawm lub zog ntawm tus nqi kuaj, thiab lwm yam.
3. SMT los ua ke ua
Solder paste printing thiab reflow cub tawg tswj kub yog lub ntsiab lus tseem ceeb. Nws yog ib qho tseem ceeb heev rau kev siv laser steel mesh nrog cov khoom zoo thiab ua tau raws li cov txheej txheem cov cai. Raws li cov kev xav tau ntawm PCB, qee ntawm lawv yuav tsum tau nce lossis txo qis cov hlau mesh qhov taub, lossis siv U-puab lub qhov los ua cov hlau mesh raws li cov txheej txheem yuav tsum tau ua. Lub tshuab ua kom sov thiab kev tswj ceev ntawm reflow soldering yog ib qho tseem ceeb heev rau cam muab tshuaj txhuam infiltration thiab vuam kev cia siab. Nws tuaj yeem raug tswj hwm raws li cov haujlwm SOP ib txwm ua. Ntxiv rau, AOI kev soj ntsuam yuav tsum tau ua nruj me ntsis kom txo qis cov kev tsis zoo uas tshwm sim los ntawm tib neeg yam.
4. ntsaws ntsaws hauv kev tsim khoom
Nyob rau hauv txheej txheem ntawm plug-in, lub pwm tsim ntawm dua yoj soldering yog lub ntsiab lus tseem ceeb. Kev siv pwm txhawm rau ua kom qhov tshwm sim ntawm cov khoom lag luam zoo tom qab lub tshuab ua kom sov yog txheej txheem uas PE engineers yuav tsum tau xyaum ua ntu zus thiab suav sau lub sijhawm yav dhau los.
5. Raug rho tawm haujlwm
Hauv daim ntawv tshaj tawm DFM dhau los, nws tau hais kom teeb tsa qee qhov kev ntsuas ntawm PCB txhawm rau ntsuas txuas ntxiv ntawm PCB thiab PCBA Circuit Court tom qab muag tag nrho cov khoom. Yog tias ua tau, cov neeg tuaj yeem tuaj yeem yuav tsum muab cov kev pabcuam los hlawv cov program rau hauv kev tswj loj ntawm IC los ntawm cov hlawv (xws li st-txuas, j-txuas, thiab lwm yam), yog li cov haujlwm hloov pauv tau los ntawm ntau cov kev ua kov tau tuaj yeem kuaj tau ntau dua. , kom kuaj xyuas lub cev muaj nuj nqi ntawm tag nrho PCBA.
6. PCBA board xeem
Rau qhov kev txiav txim siab nrog PCBA qhov yuav tsum tau xeem, cov khoom ntsuas tseem ceeb suav nrog ICT (hauv kev sib tw Circuit), FCT (muaj nuj nqi kuaj), hlawv hauv kev sim (kev kuaj kev laus), ntsuas kub thiab av noo, ntsuas kev xeem, thiab lwm yam, uas tuaj yeem ua haujlwm raws rau tus neeg muas zaub' s kev xeem qauv thiab cov ntaub ntawv qhia tuaj yeem sau lub ntsiab lus.
