Cinga ngeemfuno zeprojekthi yakho. Sebenzisa i-ENIG ngokufikelelekayo, uyilo olulula. Khetha i-ENEPIG kwiiprojekthi ezinzima ezifuna ukuqina, ukubopha ucingo, okanye ukuxhathisa umhlwa. Qwalasela uhlahlo lwabiwo-mali lwakho, okusingqongileyo, kunye neemfuno zokusebenza.
Icebiso: Kwiiprojekthi ezifuna ukuthembeka okuphezulu, i-ENEPIG ixabisa iindleko ezongezelelweyo.
4. Ngaba i-ENEPIG ihlala ixesha elide kune-ENIG?
Ewe, i-ENEPIG ihlala ixesha elide kuba umaleko wayo we-palladium unqanda umhlwa kunye nokunxiba. I-ENIG ikwaxhathisa umhlwa kodwa ayomelelanga kangako kwiimeko ezinzima. Ukugcina ukugqiba zombini ngokufanelekileyo kubanceda bahlale ixesha elide.
5. Ngaba i-ENIG kunye ne-ENEPIG zikhuselekile kwindalo esingqongileyo?
Zombini iziqendu ziyalandela Imithetho ye-RoHS, ngoko ke zi-eco-friendly. I-ENIG isebenzisa izixhobo ezimbalwa, ngelixa inkqubo ye-ENEPIG ibandakanya iikhemikhali ezininzi. Jonga kumenzi wakho ngezenzo eziluhlaza.
Phawula: Ubomi obude be-ENEPIG bunokunciphisa inkunkuma ngokwenza ii-PCBs zihlale ixesha elide.
