Malinga ndi njirayi, sinema wa PCB ikhoza kugawidwa m'magulu otsatirawa:

1. Mabowo amange chidutswa cha chitsulo chomwe chimafanana ndi mapepala a PCB bolodi. Kenako gwiritsani ntchito msirikali popita ku bolodi ya PCB kudzera pa cholembera. Mukasindikiza wogulitsa, gwiritsani ntchito msirikali pamwamba pa cholembera, pomwe gulu la madera limayikidwa pansi pa chimbudzi, kenako gwiritsani ntchito scraper messell pazenera. Kutsika kwa mauna ndikuphimba gulu la madera. Ikani zigawo zotsalazo, ndipo gulu lowala likhoza kuchitidwa mosafanana, ndipo pulagikilo-m'magawo omwe ali ndi mfuti.

2. Chingwe chofiira cha pulasitiki: Kutsegulidwa kumatsegulidwa pakati pa mapepala awiri a chinthucho molingana ndi kukula ndi mtundu wa gawo. Gwiritsani Ntchito Kuyika (Kuyika Kugwiritsa Ntchito Air Kuyikika Kuti Muzilotsere Guluu la Kutalika Kwambiri Pamutu Wapadera) Kuti mulowetse guluu la PCB kudzera pa mauna a PCB. Kenako lembani zigawozo, ndipo zigawo zikuluzikuluzing'ono zimaphatikizidwa ndi PCB, pulagi mu pulagi-mu zigawo ndikudutsa msipu wa funde limodzi.

3. Zosanja zamagetsi: pomwe PCB imayenera kukhazikitsidwa ndi gulu la ogulitsa ndi guluu lofiira, ndiye kuti zikwangwani zofiira pawiri zimafunikira kugwiritsidwa ntchito. Zolemba zapamwamba zimapangidwa ndi zolembera ziwiri, chosanja chimodzi cha laser ndi cholembera chimodzi. Kodi mungadziwe bwanji ngati mungagwiritse ntchito cholembera kapena guluu lofiira la slider? Choyamba mumvetsetse ngati kutsuka wa slider phala kapena guluu wofiira. Ngati msirikali amagwiritsidwa ntchito koyamba, ndiye kuti walonda wa alonda amapangidwa kukhala cholembera wamba cha laser, ndipo cholembera chofiyira chofiyira chimapangidwa kukhala cholembera. Ngati guluu wofiira amagwiritsidwa ntchito koyamba, ndiye kuti cholembera chofiyira chofiyira chimapangidwa mu chosanja wamba la laser, ndipo wogulitsa wa alonda amapangidwa kukhala cholembera.
