Ikibaho cyumuzingo cyacapwe (PCBs) nintwari zitavuzwe zikoranabuhanga rigezweho, zitanga imikorere kubikoresho bya elegitoronike dukoresha burimunsi. Mugihe ibikorwa byabo byimbere ari ingingo ishyushye, ikintu kimwe cyihariye akenshi kirengagizwa - ibara ryabo. Wigeze wibaza impamvu PCBs yiganjemo icyatsi kibisi? Muri iyi blog, tuzacengera mubintu byamateka, tekiniki, nibikorwa bifatika byatumye PCBs ikundwa cyane.
Inkomoko y'amateka:
Kugira ngo twumve impamvu icyatsi cyahindutse ibara ryo guhitamo PCBs, dukeneye gusubira mu kinyejana cya 20 rwagati. PCB yambere yakozwe hakoreshejwe substrate yitwa Bakelite, ibikoresho byiziritse bifite ibara ryijimye. Nyamara, uko ikoranabuhanga ryateye imbere, inganda zahindutse muburyo bwiza kandi bushimishije.
Kugenda icyatsi:
Mu myaka ya za 1960, uruganda rwa elegitoroniki rwatangiye gukoresha epoxy resin nkibikoresho byo munsi yubutaka kubera amashanyarazi meza cyane hamwe nubukanishi. Ibisigarira kandi bitanga inyungu yongeyeho - ubushobozi bwo kurangi. Icyatsi ni ibara ryo guhitamo gusa kuko birashoboka kandi byoroshye kubakora. Tanga uburyo bwiza bwo kurangiza kuri PCB utwikiriye ibimenyetso byumuringa hamwe na wino yo kugurisha icyatsi kibisi.
Ibitekerezo bifatika:
Usibye ibintu byamateka, ibitekerezo bifatika byagize ingaruka no gukundwa kwa PCBs. Reka dusuzume impamvu ebyiri zingenzi:
1. Itandukaniro no gukara:
Abashakashatsi ba elegitoroniki n'abashushanya bahitamo icyatsi kuko gitandukanye numutuku, ibara gakondo rya wino yo kugurisha. Itandukaniro rihuza ibara ritukura nicyatsi byoroha kumenya amakosa yose mubikorwa byo gukora no guteranya. Ubwiyongere bwiyongereye bugabanya cyane amahirwe yamakosa kandi bikazamura ubwiza rusange bwibikorwa bya PCB.
2. Umunaniro w'amaso:
Indi mpamvu yihishe inyuma yo guhitamo icyatsi ifitanye isano nubwubatsi bwabantu. Gukorana nibikoresho bya elegitoronike na PCB bisaba amasaha yo kureba kumuzunguruko utoroshye hamwe nibice bito. Icyatsi gikundwa kuko ni ibara rigabanya uburibwe bwamaso nubwonko, bigatuma abatekinisiye bakora igihe kinini nta kubangamira cyangwa gutakaza ukuri. Ingaruka nziza yicyatsi kumaso ituma biba byiza gukoreshwa igihe kirekire.
Ubundi buryo bugezweho:
Mugihe PCBs zicyatsi ziganje munganda mumyaka mirongo, udushya tugezweho twaguye palette ya PCBs. Uyu munsi, urashobora kubona PCBs mumabara atandukanye, kuva mubururu numutuku kugeza umukara ndetse byoroshye. Ihitamo ryerekana porogaramu zihariye, ibyifuzo byuburanga, cyangwa ibisabwa byihariye byo kuranga. Nubwo, nubwo intera yagutse ihari, icyatsi gikomeza kuba ibara rikoreshwa cyane kubera igiciro-cyiza, kumenyera no kwizerwa.
Icyamamare cya PCBs icyatsi gishobora kwitirirwa guhuza ibintu byamateka, ikoranabuhanga nibikorwa bifatika. Kuva mu mizi yacyo ya mbere muburyo buhendutse kandi bwinshi bwa epoxy yicyatsi, kugeza igihe cyarushijeho gusobanuka no kugabanuka kwamaso, ibara ryabaye kimwe ninganda za elegitoroniki. Mugihe isoko ubu itanga urutonde runini rwamahitamo, ntawabura kuvuga ko PCB yicyatsi izakomeza kuganza ejo hazaza.
