Mu myaka yashize, hafi umuntu umwe afite ibikoresho byinshi bya elegitoronike, kandi inganda za elegitoroniki zateye vuba, zikaba nanone byateje imbere kuzamuka kwingufu za PCB. Mu myaka yashize, abantu bafite ibisabwa byinshi kandi byisumbuye kubicuruzwa bya elegitoroniki, bikaba byarateje ibisabwa byinshi kandi bisabwa kurwego rwumuzunguruko. Uburyo bwo gutandukanya ibibaho byumuzunguruko bya PCB byabaye ingingo yo kongera impungenge.

Uburyo bwa mbere ni ubugenzuzi bugaragara, burimo kugenzura ahanini kureba isura yinama yumuzunguruko. Ikintu cyibanze cyane kugirango urebe isura ni ukugenzura niba ubugari nubunini bwinama yinama buhuye nubunini nibisobanuro ukeneye. Niba bidashoboka, ugomba kongera kubikora. Byongeye kandi, hamwe n'amarushanwa akaze ku isoko rya PCB, ibiciro bitandukanye bikomeje kuzamuka. Kugirango ugabanye ibiciro, abakora bamwe bakomeje kugabanya ibiciro byibikoresho no kugura umusaruro. HB, CEM-1, impapuro 3 zifite imikorere mibi kandi biroroshye kuyihindura, kandi birashobora gukoreshwa gusa kumusaruro wimipaka, mugihe cyakozwe gusa umusaruro umwe, mugihe cyakoreshejwe neza mu mbaraga nimikorere, kandi akenshi bikoreshwa muburyo bubiri kandi bwimpande zombi. Umusaruro w'amazi. Imbari zikozwe mu myambarire yo mu cyiciro gito akenshi ifite ibice n'ibishushanyo, bigira ingaruka zikomeye ku mikorere y'imbaho. Aha kandi aho ukeneye kwibanda kubugenzuzi bugaragara. Byongeye kandi, niba umugurisha mask ink urusakuro aringaniye, yaba umuringa washyizwe ahagaragara; Niba ecran ya silik ya silik irangiye, niba pagi iriho cyangwa idakeneye kwitabwaho.

Nyuma yuburyo bwa kabiri bugomba gukoreshwa, burasohoka binyuze mubitekerezo bikora. Mbere ya byose, irashobora gukoreshwa mubisanzwe nyuma yibi bigize. Ibi bisaba ko ikigo cyumuzunguruko kidafite umuzunguruko mugufi cyangwa umuzenguruko ufunguye. Uruganda rufite uburyo bwo kwipimisha amashanyarazi mugihe cyo gutanga kugirango tumenye niba ikigo gifite umuzunguruko ufunguye cyangwa ngufi. Icyakora, abakora inama y'ubutegetsi bazigama ikiguzi, hasezeranijwe kuri Jiezi, hasezeranijwe 100% by'amashanyarazi), bityo iyi ngingo igomba gusobanurwa mugihe gisuzuma akanama k'umuzunguruko. Noneho reba ikibaho cyumuzunguruko kubushyuhe mugihe cyo gukoresha, kijyanye no kumenya niba umurongo wa kabiri / umurongo uturere two kunama kubwongereza. Iyo ugurishije patch, birakenewe kugenzura niba padiri yaguye munsi yubushyuhe bwinshi, butuma bidashoboka kubagurisha. Byongeye kandi, ubushyuhe bwinshi bwo kurwanya ubushyuhe kandi ni ngombwa cyane. Ironderero ryingenzi ryinama ni agaciro ka TG. Mugihe wakoze isahani, injeniyeri akeneye kwigisha uruganda rwinama kugirango akoreshe ikigo gihuye ukurikije imiterere itandukanye. Hanyuma, igihe gisanzwe cyo gukoresha nicyo kimenyetso cyingenzi cyo gupima ireme ryikibaho.

Iyo tuguze imbaho ​​z'umuzunguruko, ntidushobora gutangirira ku giciro wenyine. Tugomba kandi gusuzuma ubwiza bwinama yumuzunguruko kandi dusuzume ibintu byose mbere yuko dushobora kugura imbaho ​​zihenze.
