M'moyo watsiku ndi tsiku, bolodi yozungulira yamagulu ambiri a PCB ndiyomwe imagwiritsidwa ntchito kwambiri pagulu. Ndi gawo lofunikira chotero, liyenera kupindula ndi maubwino ambiri a bolodi lozungulira la PCB. Tiyeni tione ubwino wake.
5. Ikhoza kupanga dera lokhala ndi vuto linalake, lomwe lingathe kupanga maulendo othamanga kwambiri;
6. Circuit, magnetic circuit shielding layer ikhoza kukhazikitsidwa, ndipo zitsulo zazitsulo zowonongeka zowonongeka zingathenso kukhazikitsidwa kuti zikwaniritse zofunikira za ntchito zapadera monga kutetezera ndi kutaya kutentha.
Ndi chitukuko chosalekeza cha umisiri wamagetsi ndi kuwongolera kosalekeza kwa zofunikira pazida zamagetsi pakompyuta, zamankhwala, zoyendetsa ndege ndi mafakitale ena, gulu loyang'anira dera likupanga njira yochepetsera voliyumu, kuchepetsa khalidwe komanso kuchulukana. Chifukwa cha kuchepa kwa malo omwe alipo, matabwa osindikizidwa amtundu umodzi kapena awiri sangathe kukwaniritsa kuwonjezeka kwa kachulukidwe ka msonkhano. Choncho, m'pofunika kuganizira kugwiritsa ntchito matabwa ozungulira ma multilayer okhala ndi chiwerengero chapamwamba cha zigawo ndi kachulukidwe kapamwamba ka msonkhano. Ma board ozungulira a Multilayer akhala akugwiritsidwa ntchito kwambiri popanga zinthu zamagetsi chifukwa cha mawonekedwe ake osinthika, okhazikika komanso odalirika amagetsi komanso magwiridwe antchito apamwamba azachuma.
