Kev ua tiav cov khoom lag luam traceability yog qhov zais tab sis qhov tseem ceeb ntawm kev lag luam PCBA niaj hnub, uas tsis tshua muaj hais nyob rau hauv cov ntawv tshaj tawm kev lag luam. Nws sau txhua qhov txuas los ntawm cov khoom siv raw mus rau kev xa khoom tiav, thiab khiav los ntawm tag nrho lub neej voj voog ntawm PCBA cov khoom.
Txhua batch ntawm PCBA yuav muab ib tug cim traceability code tom qab ntau lawm. Cov cai no sib raug rau cov ntaub ntawv tiav, suav nrog cov ntaub ntawv xws li PCB pawg thawj coj saib, cov khoom lag luam, cov kab ntau lawm, cov neeg ua haujlwm khiav haujlwm, sijhawm ntau lawm thiab tag nrho cov ntaub ntawv xeem. Thaum cov khoom txawv txav tshwm sim hauv kev ua lag luam, cov kws tshaj lij tuaj yeem nrhiav qhov chaw ntawm cov teeb meem sai sai los ntawm kev nug cov cai, txiav txim seb qhov tsis xws luag los ntawm cov khoom siv raw, cov txheej txheem tsim khoom lossis kev siv tsis raug.
Cheebtsam traceability yog lub hauv paus ntawm tag nrho cov system. Hauv kev tswj hwm nruj zoo xws li cov khoom siv hluav taws xob hauv tsheb thiab cov khoom siv hluav taws xob kho mob, txhua tus resistor, capacitor thiab nti yuav tsum khaws cov ntaub ntawv soj ntsuam tuaj thiab cov lej batch. Thaum qee hom kev tivthaiv muaj kev pheej hmoo zoo thoob ntiaj teb tshaj tawm los ntawm cov neeg muag khoom, cov tuam txhab lag luam tuaj yeem tshuaj xyuas cov khoom cuam tshuam sai thiab ua kom rov qab los yog tshuaj xyuas, txo qis kev pheej hmoo ua haujlwm.
Ntxiv nrog rau kev tiv thaiv kev pheej hmoo, cov txheej txheem traceability kuj ua kom zoo dua tom qab - kev muag khoom thiab kev tswj cov khoom muag. Tom qab tau txais kev thov kev saib xyuas, engineers tuaj yeem saib cov khoom qub tsis tau los ntawm cov ntaub ntawv traceability thiab txhim kho kev txij nkawm. Rau cov tuam txhab, cov ntaub ntawv loj uas tau sau los ntawm traceability kuj tseem tuaj yeem pab txheeb xyuas cov khoom lag luam zoo thiab txhim kho cov txheej txheem hauv lub hom phiaj.
Niaj hnub no, ntau thiab ntau dua nruab nrab - mus rau - siab - cov neeg siv khoom kawg suav hais tias yog qhov kev nkag mus tau yooj yim raws li qhov yuav tsum tau ua. Txawm hais tias nws nce qee cov nqi tswj hwm, nws coj tau ntev - lub sij hawm lav rau cov qauv kev lag luam thiab kev ntseeg siab ntawm PCBA cov lag luam.
