Guhindura byihuse pcb hejuru yubuvuzi HASL LF RoHS

Inzira yumuzunguruko ya HASL muri rusange yerekeza kuri padi HASL, igomba gutwikira amabati kumwanya wa padi hejuru yubuyobozi bwumuzunguruko.Irashobora kugira uruhare mu kurwanya ruswa no kurwanya okiside, kandi irashobora kandi kongera aho uhurira hagati ya padi nigikoresho cyagurishijwe, kandi ikazamura ubwizerwe bwo kugurisha.Inzira yihariye ikubiyemo intambwe nyinshi nko gukora isuku, kubika imiti ya tin, gushiramo, no koza.Noneho, muburyo nko kugurisha umwuka ushushe, bizitwara kugirango bibe isano hagati y amabati nigikoresho cyo kugabana.Gutera amabati ku mbaho ​​z'umuzunguruko ni inzira ikoreshwa kandi ikoreshwa cyane mu nganda zikora ibikoresho bya elegitoroniki.

Kurongora HASL hamwe na HASL idafite isuku nuburyo bubiri bwo kuvura hejuru bukoreshwa cyane cyane mukurinda ibyuma bigize imbaho ​​zumuzunguruko kwangirika no kwangirika.Muri byo, ibiyobora HASL bigizwe na tin 63% na 37% by'isasu, mugihe HASL idafite isasu igizwe n'amabati, umuringa nibindi bintu bimwe na bimwe (nka silver, nikel, antimoni, nibindi).Ugereranije na HASL ishingiye ku isasu, itandukaniro riri hagati ya HASL idafite isuku ni uko ryangiza ibidukikije, kuko isasu ni ibintu byangiza ibidukikije n’ubuzima bw’abantu.Mubyongeyeho, kubera ibintu bitandukanye bikubiye muri HASL idafite isasu, kugurisha no kugurisha amashanyarazi biratandukanye gato, kandi bigomba guhitamo ukurikije ibisabwa byihariye bisabwa.Muri rusange, ikiguzi cya HASL kitagira isasu kiri hejuru gato ugereranije nicyuma cya HASL, ariko kurengera ibidukikije no kubishobora ni byiza, kandi bitoneshwa nabakoresha benshi kandi benshi.

Kugirango ukurikize amabwiriza ya RoHS, ibicuruzwa byumuzunguruko bigomba kuba byujuje ibi bikurikira:

1. Ibiri muri gurş (Pb), mercure (Hg), kadmium (Cd), chromium hexavalent (Cr6 +), biphenyls polybromine (PBB) na polybromine diphenyl ethers (PBDE) bigomba kuba munsi yagaciro kagenwe.

2. Ibiri mu byuma byagaciro nka bismuth, ifeza, zahabu, palladium, na platine bigomba kuba bitarenze urugero.

3. Ibirimo halogen bigomba kuba munsi yagaciro kagenwe, harimo chlorine (Cl), bromine (Br) na iyode (I).

4. Ikibaho cyumuzunguruko nibigize bigomba kwerekana ibirimo nimikoreshereze yibintu byangiza kandi byangiza.Ibyavuzwe haruguru ni kimwe mu bintu by'ingenzi bisabwa kugira ngo imbaho ​​z’umuzunguruko zubahirize amabwiriza ya RoHS, ariko ibisabwa byihariye bigomba kugenwa hakurikijwe amabwiriza n’ibanze.
