Thaum raug cov PCBs, nws yog ib qho tseem ceeb kom ua kev tshuaj xyuas ntawm txhua theem. Qhov kawg no pab rau kev txheeb xyuas thiab kho qhov tsis xws luag hauv PCB, ntawm no yog qee txoj hauv kev los txheeb xyuas PCB tsis xws luag:

Kev Ntsuam Xyuas Pom: Pom Kev Pom Zoo yog feem ntau hom tshuaj ntsuam thaum Pcb los ua ke. Cov cuab yeej tshwj xeeb tuaj yeem nruab rau kev tshuaj ntsuam xyuas raws li cov hom phiaj tshuaj xyuas. Refowed sold cov pob qij txha ntawm PCBs feem ntau tau soj ntsuam siv prisms, uas pab tau xaiv ntau yam kev tsim khoom. Kev siv prism spectroscopy, teeb pom kev zoo tuaj yeem cuam tshuam nrog PCB lossis PCB cov pob qij txha to taub cov teeb meem hauv PCB tsim thiab contours.

X-ray soj ntsuam (Axi): Tshawb cov khoom siv, sib koom ua ke, thiab lwm yam ua txhaum yuav tshwm sim tom qab ntau lawm. Nrog cov thev naus laus zis thev naus laus zis yog ci ntsa iab ncaj qha rau ntawm PCB los ua ke, uas siv cov xoo hluav taws xob nqus los tsim cov duab. Xoo hluav taws xob tshuaj xyuas pab txheeb xyuas ntau yam ntawm cov chaw sib dhos, cov pob qij txha thiab cov pob qij txha thiab cov pob zeb semiconduct, thiab lwm yam.

Automated lwj excection (AOI): thaum lub zog soj ntsuam kho qhov muag, ib lossis ntau lub koob yees duab yog siv los ntsuas PCB. Lub koob yees duab khw muag duab ntawm ntau qhov chaw ntawm cov ces kaum sib txawv thiab txoj haujlwm. Cov duab no tuaj yeem txheeb xyuas los ntawm cov neeg tsim qauv lossis cov engineers nyob rau PCB los ua ke cov txheej txheem, uas yuav pab kuaj tsis xws luag, stains, thiab lwm yam tsis xws luag. Nrog txoj kev no peb tuaj yeem txheeb xyuas skewed lossis tsis muaj feem xyuam. Yog li ntawd, lub kaw lus tuaj yeem siv ntau yam 3D AOIS txhawm rau txhawm rau txhawm rau qhov siab thiab dav ntawm tus PCB thiab qhov sib txawv ntawm cov PCB sib txawv.
