Waxaa jira tilmaamo badan oo ku saabsan dhamaystirka dusha sare, sida HASL-ka-la'aanta rasaasta waxay dhibaato ku tahay inay yeelato guri siman.Electrolytic Ni/au runtii waa qaali haddii dahab badan lagu shubo suufka, waxay u horseedi kartaa kala goysyada alxanka.Daasadda Immersion waxay leedahay xaalufka alxanka ka dib soo-gaadhista wareegyada kulaylka badan, sida dhinaca sare iyo hoose ee PCBA habka dib-u-soo-celinta, iwm.Jadwalka hoose wuxuu muujinayaa qiimayn qalafsan oo loogu talagalay dhammaysyada dusha sare ee inta badan la dabaqo ee looxyada wareegga daabacan.

Nolosha shelf waa shay muhiim ah oo aad u baahan tahay inaad tixgeliso markaad samaynayso jadwalkaaga wax soo saarka.Nolosha shelfwaa daaqada qalliinka ee ku siinaysa dhamaystirka in la helo alxanka PCB dhamaystiran.Waa muhiim in la hubiyo in dhammaan PCB-yadaagu ay ku urursan yihiin nolosha shelf.Marka lagu daro walxaha iyo habka samaynta dhamaystirka dusha sare, nolosha shelf ee dhamaadka si xoogan ayaa loo saameeyaaBaakadaha PCB-yada iyo kaydinta.Codsadaha habka saxda ah ee kaydinta ee ay soo jeediyaan tilmaamaha IPC-1601 waxay ilaalin doonaan alxanka iyo isku halaynta dhamaystirka.
