Mutu wokwera uli ndi ntchito za kuzungulira kwa angular, kukwera ndi kugwa, vacuum adsorption ndi zina zotero. Kuyenda kwa ntchito ndikuti mutu wokwera umatembenukira pa vacuum adsorption ndipo makina ogwa amatsitsa mutu wokwera kuti ufike pamalo odyetsera a wodyetsa. Pambuyo poyamwa zigawozo, mutu wokwera umakwezedwa, kumaliza kujambula zithunzi kudzera pa kamera yofulumira, kenaka imasunthira kumalo a chipangizo pamwamba pa PCB, ndipo mutu wokwera umatsikira kumalo ogwirizana a chipangizo cha PCB, Pambuyo potsekedwa. , thupi ndi lamphamvu ndipo mutu umakwezeka.
