PCB plaub txheej boardtau dhau los ua ib qho tseem ceeb hauv kev lag luam hluav taws xob niaj hnub no. PCB plaub txheej board yog dav siv hauv kev lag luam xws li khoos phis tawj, kev sib txuas lus, khoom siv hluav taws xob, thiab lwm yam. Txawm hais tias nws yog cov khoom siv hluav taws xob siv hluav taws xob lossis cov khoom siv hluav taws xob ua lag luam, PCB plaub txheej pawg thawj coj saib yuav tsum tau ua. Yog li ntawd, lub sijhawm thiab cov txheej txheem ua haujlwm yuav tsum tau ua rau kev tsim cov batch PCB plaub txheej boards yog qhov tseem ceeb.
Feem ntau hais lus, lub voj voog ntau lawm rau batch PCB plaub txheej boards nyob ib ncig ntawm 10-15 hnub. Lub voj voog ntau lawm muaj ntau theem xws li tau txais kev txiav txim, lees paub qhov yuav tsum tau ua, tsim cov duab kos duab, ua cov qauv, ua cov kev sim ntau lawm, ntau lawm, tshuaj xyuas zoo, ntim thiab xa khoom. Yuav tsum ua tiav cov txheej txheem tsim khoom kom ntseeg tau cov qauv zoo thiab lub sijhawm xa khoom raug.
Ua ntej, tau txais kev txiav txim thiab lees paub qhov yuav tsum tau ua yog cov ntsiab lus pib ntawm lub voj voog ntau lawm. Lub Hoobkas yuav tsum tau sau cov neeg siv khoom tsim cov ntaub ntawv thiab pawg thawj coj saib xyuas cov ntaub ntawv, tshuaj xyuas thiab lees paub cov ntaub ntawv tsim thiab cov kev xav tau, xyuas kom meej tias tus qauv tsim tuaj yeem ua tau raws li qhov yuav tsum tau ua, thiab muab cov lus hais tsim nyog.
Tom ntej no, tsim cov duab kos duab yog kauj ruam thib ob ntawm lub voj voog ntau lawm. Cov kauj ruam no yuav tsum tau ua kom tiav thiab raug PCB plaub txheej board tsim duab kos duab, suav nrog kev xaim, kev tswj hwm impedance, kev npaj cov khoom ntawm lub rooj tsavxwm, ntxiv cov ntaub qhwv, thiab lwm yam. Cov kauj ruam no yuav tsum muaj kev txhawb nqa ntawm lub computer-aided tsim (CAD) thiab computer-aided manufacturing (CAM) technologies.
Qauv ntau lawm yog theem peb ntawm lub voj voog ntau lawm. Feem ntau, txhawm rau kom ntseeg tau tias cov txiaj ntsig tsim khoom tiag tiag sib luag ntawm cov qauv tsim, cov chaw tsim khoom yuav ua cov qauv me me rau cov neeg siv khoom thiab xaiv cov qauv ua tau zoo tshaj plaws rau kev sim ntau lawm.
Kauj ruam plaub yog los ua kev sim ntau lawm. Kev sim ntau lawm yog txhawm rau txheeb xyuas ntau yam tsis sib xws thiab cov txheej txheem tsim khoom hauv kev tsim khoom tiag tiag, xws li calibration, tshav kub shrink, thiab lwm yam, kom ntseeg tau tias cov khoom zoo raws li cov neeg siv khoom xav tau. Tom qab ua tiav qhov kev sim ntawm cov khoom, cov neeg siv khoom yuav ntsuas cov khoom.
Kauj ruam tsib yog kev tsim khoom loj. Tom qab paub meej tias cov qauv zoo ua tau raws li cov qauv, lub Hoobkas yuav loj tsim PCB plaub txheej boards nrog tib lub tswv yim tsim siv tib cov txheej txheem ntau lawm. Txhua lub rooj tsavxwm tau dhau los ua tiav cov txheej txheem tsim khoom thiab kev tshuaj xyuas zoo kom ntseeg tau tias cov khoom ua tau raws li cov neeg siv khoom xav tau tom qab ua haujlwm.
Kauj ruam thib rau yog kev soj ntsuam zoo. Thaum lub sij hawm tsim cov txheej txheem, txhua lub PCB plaub txheej pawg thawj coj yuav raug tshuaj xyuas thiab kuaj xyuas kom ntseeg tau tias cov khoom zoo thiab cov txheej txheem tsim ua tau raws li qhov yuav tsum tau ua. Qhov no feem ntau yog ua tiav thaum kawg ntawm kev tsim khoom kom ntseeg tau tias QC cov qauv tau ntsib hauv txhua pawg.
Cov kauj ruam kawg yog pob thiab nkoj. Tom qab tag nrho cov khoom tau raug soj ntsuam zoo, lub Hoobkas yuav faib, ntim, thiab xa mus rau cov neeg siv khoom qhov chaw xaiv.
