PCB Assembly Defect Coverage Pogwiritsa ntchito Automated Optical Inspection (AOI)

Automated Optical Inspection (AOI), yomwe ndi kuyang'ana kowona kwa makina osindikizira a Printed Circuit Board (PCB), imapereka 100% chigawo chowoneka ndi kuyang'ana pamodzi ndi ogulitsa.Njira yoyeserayi yakhala ikugwiritsidwa ntchito popanga PCB kwa zaka pafupifupi makumi awiri.Zimagwira ntchito yofunika kwambiri powonetsetsa kuti pasakhale zolakwika mwachisawawa pamsonkhano.Njirayi, yomwe imagwiritsa ntchito zowunikira, makamera, ndi makompyuta owonera, imaphatikizidwa pakuphatikizana kuti zitsimikizire mtundu wapamwamba kwambiri munthawi yonse ya moyo wazinthu.Njirayi imathandizira kuyang'ana mofulumira komanso molondola ndipo ingagwiritsidwe ntchito pazigawo zosiyanasiyana za kupanga.Chifukwa chake, ndi zinthu ziti zomwe chida cha Automated Optical Inspection (AOI) chingayang'ane paMsonkhano wa PCB?

Kuzindikira Zowonongeka Pogwiritsa Ntchito AOI

Mwamsanga zolakwazo zidziŵika, zimakhala zosavuta kupanga kupanga komaliza kuti kugwirizane ndi zofunikira zapangidwe popanda zolakwika zilizonse.Ukadaulo wodziwika bwino, wovomerezekawu ungagwiritsidwe ntchito kuyang'ana zotsatirazi pagulu la PCB:

• Manodules, zotupa ndi madontho
• Tsegulani mabwalo, zazifupi ndi kupatulira kwa solder
• Zolakwika, zosowa komanso zokhotakhota
• Malo osakwanira phala, kupaka, ndi mlatho
• tchipisi chosowa kapena chotsitsa, tchipisi chokhotakhota ndi zolakwika za chip-orientation
• Milatho ya Solder, ndi mayendedwe okwera
• Kuphwanya mzere m'lifupi
• Kuphwanya malo
• Mkuwa wochuluka, ndi phala losowa
• Tsatani zazifupi, kudula, kudumpha
• Zowonongeka m'dera
• Kuchepetsa kwazinthu, polarity yamagulu,
• Kukhalapo kwa chigawocho kapena kusakhalapo, chigawocho chimasokonekera kuchokera pamapepala okwera pamwamba
• Kuchulukirachulukira kwa ma solder ndi ma solder osakwanira
• Zigawo zopindika
• Matani mozungulira ma lead, milatho ya solder, ndi kulembetsa phala la solder

 

Ndi zolakwika izi zomwe zimadziwika poyambilira, opanga amatha kupanga bolodi molingana ndi zofunikira.Kuti muthandizire pakuyesaku, pali zida zingapo zomwe zimapezeka zowunikira zapamwamba, zowonera, komanso kuthekera kokonza zithunzi kuti zisawonongeke mwapadera.Makinawa amapereka magwiridwe antchito osavuta, anzeru komanso amphamvu, zomwe zimapangitsa kuti muchepetse mtengo wokonzanso ndikuwongolera kuyesa.AOI pokhala njira yoyesera yomwe imatsimikizira ubwino wa gulu lonse, ndikofunika kupeza chithandizo kuchokera ku makampani otsogola.Nthawi zonse ndi chisankho chabwino kuyanjana ndi opanga PCB omwe amapereka kuyesa kwa AOI pamanja.Izi zimathandiza wopanga kuyesa bolodi pagawo lililonse la msonkhano popanda kuchedwa.
