Yuav tsum them sai sai rau qhov tsim txhuas PCB
May 30, 2018

Aluminium PCB Lub zauv ntawm pcb yuav tsum tau them sai sai rau ntau qhov chaw, hauv qab no los ntawm 5 ntsiab lus rau koj hais .

qhov kev tsim qauv rau kab kev tsim qauv: vim tooj liab, qhov dav dav kom qee lub nyiaj, los yog tom qab tus neeg ua haujlwm tsis pom kev zoo, tus neeg tsis tau txais, kab dav nyiaj them rau qhov txuam nrog kev.

2 , printing solder uniformity: vim hais tias cov duab tom qab etching kab tooj liab tuab ultra pa, printing solder nyuaj, skipping, tuab heev, dhau cov neeg nyias nyias tsis tau. Yuav ua li cas luam tawm ib txheej ntawm ntsuab yog ib qho ntawm cov teeb meem.

3 , tom qab ua txhaum, kev cuam tshuam linewidth yuav tsum ua kom tau raws li tus neeg yuav tsum tau kos duab. Tsis pub siv tooj liab, los yog riam scraping riam, kos cov txheej txheem insulating, qhov kev ntsuas ntawm qhov kev pom muaj zog, tawm los ntawm sparks.

4 , mechanical processing: aluminium phaj drilling yuav ua tau, tab sis tom qab drilling tsis pub muaj burrs nyob rau hauv lub qhov, qhov no yuav cuam tshuam rau lub dielectric voltage withstand kev xeem. Routing thiab tsos yog qhov nyuaj heev. Thiab xuas nrig, yuav tsum tau siv pwm txhim kho, pwm ua yog ib qho txuj ci, nws tseem yog ib qho nyuaj ntawm txhuas PCB. Tom qab txoj kev zoo nkauj, zoo heev, tsis muaj burr. Feem ntau siv kev xuas nrig ntaus, xuas nrig ntawm qhov ntxhib ntxig, tab sis xav tau los ntawm qhov txhuas, qhov kev sib txuas ntawm lub rooj tsavxwm hlais qis qis qis qis qis, thiab yog li kev txawj. Xuas nrig ntaus, pawg tub ceev xwm yuav tsum tsawg dua li 0.5%.

5 , tag nrho cov txheej txheem yuav tsum tsis txhob ntu cov nplaim: txhuas puag tsis tuaj yeem kov kov, los yog qee yam tshuaj yuav tsim tau qhov teeb meem saum toj no, dub, qhov no yog tsis tsim nyog, re polished aluminium nto, qee cov neeg tsis tau txais, thiab nws yog ib qho teeb meem uas PCB tsis tuaj yeem raug mob hauv tag nrho cov txheej txheem.
