Ngemishini ye-elekthronikhi, inani elithile lokushisa likhiqizwa ngesikhathi sokusebenza, ukuze izinga lokushisa langaphakathi lemishini likhuphuke ngokushesha. Uma ukushisa kungachithwa ngesikhathi, okokusebenza kuzoqhubeka nokushisa, futhi idivayisi izohluleka ngenxa yokushisa ngokweqile. Ukuthembeka kwemishini kagesi Ukusebenza kuzokwehla. Ngakho-ke, kubaluleke kakhulu ukwenza ukwelashwa okuhle kokukhipha ukushisa endaweni ibhodi yesifunda.

Idizayini ye-PCB iyinqubo eyehlayo elandela umklamo oyinhloko, futhi ikhwalithi yomklamo ithinta ngokuqondile ukusebenza komkhiqizo kanye nomjikelezo wemakethe. Siyazi ukuthi izingxenye ebhodini le-PCB zinebanga lazo lokushisa lendawo yokusebenza. Uma lolu bubanzi lweqiwa, ukusebenza kahle kwedivayisi kuzoncipha kakhulu noma kuhluleke, okuholela ekulimaleni kocingo. Ngakho-ke, ukuchithwa kokushisa kuwukucatshangelwa okubalulekile ekwakhiweni kwe-PCB.

Ngakho-ke, njengonjiniyela wokuklama we-PCB, kufanele sikuqhube kanjani ukukhishwa kokushisa?

Ukuchithwa kokushisa kwe-PCB kuhlobene nokukhethwa kwebhodi, ukukhethwa kwezingxenye, kanye nokuhlelwa kwezingxenye. Phakathi kwazo, ukwakheka kudlala indima ebalulekile ekusabalaliseni ukushisa kwe-PCB futhi kuyingxenye ebalulekile yedizayini yokukhipha ukushisa kwe-PCB. Lapho benza izakhiwo, onjiniyela kudingeka bacabangele izici ezilandelayo:

(1) Iklama futhi ifake izingxenye ezikhiqiza ukushisa okuphezulu kanye nemisebe emikhulu kwelinye ibhodi le-PCB, ukuze kuqhutshwe ukungena komoya okuphakathi nendawo nokupholisa ukugwema ukugxambukela kwebhodi lomama;

(2) Umthamo wokushisa webhodi le-PCB usatshalaliswa ngokulinganayo. Ungabeki izingxenye zamandla aphezulu ngendlela egxilile. Uma ingenakugwenywa, beka izingxenye ezimfushane phezulu nomfula futhi uqinisekise ukugeleza komoya opholile ngokwanele endaweni egxile ekusetshenzisweni kokushisa;

(3) Yenza indlela yokudlulisa ukushisa ibe mfushane ngangokunokwenzeka;

(4) Yenza isigaba esiphambanayo sokudlulisa ukushisa sibe sikhulu ngangokunokwenzeka;

(5) Ukuhlelwa kwezingxenye kufanele kucabangele ithonya lemisebe yokushisa ezingxenyeni ezizungezile. Izingxenye ezizwela ukushisa nokushisa (okuhlanganisa namadivaysi e-semiconductor) kufanele zigcinwe kude nemithombo yokushisa noma zihlukaniswe;

(6) Naka indlela efanayo yokungena komoya ngempoqo kanye nokungena komoya wemvelo;

(7) Amabhodi amancane engeziwe kanye namapayipi omoya emishini asendleleni efanayo nendawo yokukhipha umoya;

(8) Ngokusemandleni akho, yenza ukudonsa kanye ne-exhaust ibe nebanga elanele;

(9) Into yokushisisa kufanele ibekwe ngaphezu komkhiqizo ngangokunokwenzeka, futhi kufanele ibekwe emzileni wokugeleza komoya lapho izimo zivuma;

(10) Ungabeki izingxenye ezinokushisa okuphezulu noma amandla aphezulu emakhoneni nasemaphethelweni ebhodi le-PCB. Faka usinki wokushisa ngangokunokwenzeka, uyigcine kude nezinye izingxenye, futhi uqinisekise ukuthi umzila wokukhipha ukushisa awuvinjwanga.
