Mabhodhi ePCB edunhu anoshandiswa zvakanyanya muChina, uye zvinosvibisa zvichagadzirwa panguva yekugadzirwa kweakadhindwa edunhu mabhodhi, kusanganisira guruva nemarara mukugadzira maitiro senge masara ekuyerera uye anonamira.Kana iyo pcb bhodhi isingakwanisi kuvimbisa zvinobudirira nzvimbo yakachena, kushorwa uye kudonha kuchaita kuti pcb bhodhi ikundike, zvichikanganisa hupenyu hwebasa rechigadzirwa.Naizvozvo, kuchenesa pcb redunhu bhodhi panguva kugadzira kwacho idanho rinokosha.
Semi-aqueous yekuchenesa inonyanya kushandisa organic solvents uye deionized mvura, pamwe nehumwe huwandu hweanoshanda ejenti uye zvinowedzera.Uku kucheneswa kuri pakati pekuchenesa kwesolvent uye kuchenesa mvura.Aya makuchenesa maorganic solvents, zvinonyungudutsa zvinobvira, high flash point, low toxicity, uye akachengeteka kushandisa, asi anofanirwa kugezwa nemvura obva aomeswa nemhepo.
.
Tekinoroji yekuchenesa mvura ndiyo nzira yekusimudzira yeramangwana yakachena tekinoroji, uye zvinodikanwa kumisikidza yakachena sosi yemvura uye kuburitsa mvura yekugeza workshop.Kushandisa mvura senzira yekuchenesa, kuwedzera ma surfactants, additives, corrosion inhibitors uye chelating agents kumvura kuita nhevedzano yemvura-based cleaning agents.Aqueous solvents uye non-polar tsvina inogona kubviswa.

Inoshandiswa mukuita soldering pasina kuchenesa flux kana solder paste.Mushure mekutengesa, inoenda yakananga kune inotevera nzira yekuchenesa, isisiri yemahara yekuchenesa tekinoroji parizvino ndiyo inonyanya kushandiswa imwe tekinoroji, kunyanya mafoni ekukurukurirana zvigadzirwa zvinonyanya kushandisa imwe-nguva nzira yekutsiva ODS.Solvent kucheneswa kunonyanya kushandiswa kunyungudika kwesolvent kubvisa zvinosvibisa.Solvent yekuchenesa inoda michina yakapusa nekuda kwekukurumidza kuvhurika kwayo uye kunyungudika kwakasimba.
