PCB sampling txhais li cas?
PCB sampling yog hais txog cov txheej txheem xa cov qauv kos duab thiab cov ntaub ntawv cuam tshuam ntawm lub rooj tsav xwm Circuit Court rau cov chaw tsim khoom los tsim cov qauv me me. Los ntawm cov qauv PCB, cov neeg tsim qauv tuaj yeem tshawb xyuas seb qhov kev ua haujlwm thiab kev ua haujlwm ntawm lub rooj tsavxwm tau ua tau raws li cov qauv tsim, tsis txhob muaj teeb meem ua ntej ntau lawm.
Cov ntaub ntawv dab tsi yuav tsum raug xa mus rau cov chaw tsim khoom rau kev kuaj PCB?
1. PCB tsim cov duab kos: suav nrog cov duab kos duab, cov duab kos duab, cov ntaub ntawv laminated board, thiab lwm yam. Cov ntaub ntawv no sau tag nrho cov qauv thiab kev teeb tsa ntawm lub rooj tsav xwm Circuit Court, uas yog lub hauv paus rau cov tuam txhab tsim cov qauv.
2. Gerber cov ntaub ntawv: Gerber cov ntaub ntawv yog ib hom ntaub ntawv siv rau kev tsim hluav taws xob Circuit Court, uas muaj cov ntaub ntawv txuas thiab cov ntaub ntawv sib txuas rau txhua txheej ntawm lub rooj tsav xwm Circuit Court. Hauv PCB sampling, Gerber cov ntaub ntawv yog qhov tsim nyog los coj cov tuam txhab tsim cov qauv.
3. BOM: BOM yog ib daim nqi ntawm cov ntaub ntawv uas teev cov qauv, ntau, thiab specifications ntawm tag nrho cov Cheebtsam thiab hluav taws xob Cheebtsam yuav tsum tau nyob rau hauv lub Circuit Court board. Lub rooj BOM tuaj yeem ua kom ntseeg tau tias cov tuam txhab yuav khoom thiab nruab cov khoom raws li kev tsim qauv.
4. Solder paste ntaub ntawv: Rau Circuit Court boards siv SMT nto mount technology, solder paste ntaub ntawv yog siv los coj cov txheej txheem soldering. Cov ntaub ntawv solder paste muaj cov ntaub ntawv hais txog txoj haujlwm ntawm cov ntaub qhwv thiab cov pob qij txha, kom ntseeg tau tias cov tshuaj txhuam hniav tuaj yeem raug txau rau hauv cov ntaub qhwv.
5. Lwm cov ntaub ntawv: Nyob ntawm qhov xav tau tiag tiag, cov ntaub ntawv ntxiv xws li cov kev sim ntsuas, cov ntaub ntawv ntsuas cov ntsiab lus sib koom ua ke, thiab lwm yam yuav raug rau cov chaw tsim khoom los ua qhov kev sim ua haujlwm thiab kev debugging ntawm tus qauv.
