Kutsogolo ndi kumbuyo mbali ya pcb dera kwenikweni mkuwa zigawo.Popanga mabwalo a pcb, zilibe kanthu kuti mkuwa wosanjikiza umasankhidwa kuti ukhale wosinthika mtengo kapena kuphatikizika kwa manambala awiri ndikuchotsa, chotsatira chake ndi chosalala komanso chopanda ntchito.Ngakhale kuti thupi la mkuwa silikhala losangalala monga aluminiyamu, chitsulo, magnesium, ndi zina zotero, pansi pa maziko a ayezi, mkuwa wangwiro ndi okosijeni zimakhudzidwa kwambiri ndi okosijeni;poganizira kukhalapo kwa co2 ndi nthunzi yamadzi mumlengalenga, pamwamba pa mkuwa wonse Pambuyo pokhudzana ndi mpweya, redox reaction idzachitika mwamsanga.Poganizira kuti makulidwe a wosanjikiza mkuwa mu dera PCB ndi woonda kwambiri, mkuwa pambuyo makutidwe ndi okosijeni mpweya adzakhala quasi-okhazikika boma magetsi, amene kwambiri kuvulaza zida zamagetsi makhalidwe a mabwalo onse PCB.

Kuti bwino kupewa makutidwe ndi okosijeni zamkuwa, ndi bwino kulekanitsa kuwotcherera ndi sanali kuwotcherera mbali pcb dera pa kuwotcherera magetsi, ndi kuti bwino kukhala pamwamba pa dera pcb, akatswiri akatswiri apanga wapadera Architectural. Zopaka.Zopaka zomangamanga zoterezi zimatha kutsukidwa mosavuta pamtunda wa dera la PCB, zomwe zimapangitsa kuti pakhale makulidwe a chitetezo chomwe chiyenera kukhala chochepa thupi ndikulepheretsa kukhudzana kwa mkuwa ndi gasi.Chosanjikizachi chimatchedwa mkuwa, ndipo zopangira zomwe zimagwiritsidwa ntchito ndi chigoba cha solder
