Ungase ubone amatemu afana ne-RoHS PCB kanye ne-PCB engaholi ku-electronics. I-RoHS PCB ilandela imithetho ekhawulela izinto eziyingozi emikhiqizweni. I-PCB engenamthofu yenziwa ngaphandle kokusebenzisa umthofu. Umehluko omkhulu ukugxila kwabo. I-RoHS imayelana nokulandela imithetho yokuphepha, kuyilapho i-lead-free ikhipha umthofu ngesikhathi sokukhiqiza. Ukwazi lokhu kukusiza ukuthi ukhethe ngokuhlakanipha futhi uhlangabezane nezidingo ze-eco-friendly kanye nezobuchwepheshe.
Izitoreji Eziyinhloko
Ama-RoHS PCB anemithetho eqinile yokunciphisa izinto eziyingozi. Lokhu kubenza babe ngcono kwezemvelo.
Ama-PCB angenamthofu awawusebenzisi umthofu. Basebenzisa izinsimbi eziphephile ukuze behlise ukungcoliswa komthofu.
Kokubili i-RoHS nama-PCB angenawo umthofu alungele iplanethi. Nokho, ziyehluka ngentengo, ukusebenza, kanye nemithetho okumele ilandelwe.
Ukukhetha i-PCB efanele kuncike ezidingweni zomkhiqizo wakho, imithetho yemboni, nokuthi iyithinta kanjani imvelo.
Ukuhlola womabili ama-PCB ezimeni zangempela kukusiza ukuthi ukhethe inketho ephephe kakhulu futhi eqine kakhulu.
Iyini i-RoHS PCB?
Uhlolojikelele lwe-RoHS Directive
I-RoHS Directive imele “Ukukhawulelwa Kwezinto Eziyingozi.” Kungumthetho wokunciphisa izinto eziyingozi kuma-electronics. Yaqala e-European Union ngo-2003. Umgomo wawuwukunciphisa ukungcoliswa kwezinto ezinobuthi. I-RoHS PCB ibhodi lesifunda elihlangabezana nale mithetho. Ikhawulela izinto ezifana nomthofu, i-mercury, i-cadmium, ne-chromium. Ngokulandela i-RoHS, izinkampani zenza imikhiqizo ephephile. Le mikhiqizo isiza nokuvikela imvelo.
Izidingo Ezibalulekile Zokuthobela I-RoHS
Ukuze ulandele i-RoHS, ama-PCB kufanele agweme izinto eziyingozi. Umthetho ubeka imikhawulo yokuthi zingaki lezi zinto ezingasetshenziswa. Isibonelo, ukuhola akukwazi ukuba ngaphezu kuka-0.1% wanoma iyiphi into. Ukuhlola nokuhlola kubalulekile ukufakazela ukuthobela umthetho. Izinkampani eziningi zisebenzisa i-solder engenakho ukuhola ukuhlangabezana nale mithetho. Baphinde bagcine amarekhodi ukukhombisa ukuthi balandela izindinganiso.
Imibono Engalungile Evamile Mayelana ne-RoHS kanye Nokungaholeli
Abantu bavame ukucabanga ukuthi i-RoHS kanye nokungaholeli kusho into efanayo. I-RoHS PCB ivamise ukusebenzisa izinto ezingenamthofu, kodwa zihlukile. I-RoHS ikhawulela izinto eziningi eziyingozi, hhayi nje umthofu. Amanye ama-PCB angenawo umthofu angase abe nezinye izinto ezinomkhawulo. Ukwazi lo mehluko kukusiza ukuthi ukhethe i-PCB efanele ngezidingo zakho.
Iyini i-PCB engenamthofu?
Incazelo kanye Nezimpawu zama-PCB Angenamthofu
I-PCB engenamthofu yenziwa ngaphandle kokusebenzisa umthofu. Igwema ukuhola ezingxenyeni zayo kanye nezinto zokunamathisela. Lawa ma-PCB aphephe kakhudlwana kubantu neplanethi. Basebenzisa ezinye izinsimbi njengethayela, isiliva, noma ithusi esikhundleni somthofu.
Ama-PCB angenawo umthofu asiza ukuvikela indawo ezungezile ekungcoleni komthofu. Balandela imithetho efana ne-RoHS ukuze bahlangabezane namazinga omhlaba. Lawa ma-PCB futhi anamaphuzu aphezulu ancibilika, angashintsha indlela asebenza ngayo ngesikhathi sokukhiqiza.
Izinqubo Zokuhlanganisa Ezingakhokhelwa Umthofu
Ukwenza ama-PCB angenawo umthofu kudinga izindlela ezihlukene zokuhlanganisa. I-solder engenamthofu iyancibilika emazingeni okushisa aphezulu kune-solder esekelwe kumthofu. Isibonelo, incibilika phakathi kuka-217°C no-227°C, kuyilapho i-lead solder incibilika ku-183°C.
Kudingeka amathuluzi akhethekile kulawa mazinga okushisa aphezulu. Amahhavini agelezayo kanye nama-ayina e-soldering kufanele asethwe ngokucophelela. Abasebenzi kumele bahlole izinkinga ezifana nokuqhekeka noma amalunga abuthakathaka. Yize kunzima ukwenza, ukusoda okungenayo umthofu kuphephile futhi kungcono emhlabeni.
Umehluko Phakathi Kwama-PCB Angaholi Nawomdabu
Ama-PCB angenawo umthofu awasebenzisi umthofu, ngokungafani nalawo ajwayelekile. Ama-PCB endabuko asebenzisa i-lead solder, encibilika kalula. Ama-PCB angenawo umthofu angcono kwezempilo kanye nemvelo.
Ama-PCB angenamthofu aphatha ukushisa kangcono, awenze aqine kakhudlwana. Ama-PCB endabuko angase aphathe ugesi kangcono kancane. Lapho ukhetha, cabanga ngemithetho, i-eco-friendly, kanye nendlela esebenza ngayo.
Imithelela Yezemvelo Nezokulawula
Izinzuzo Zemvelo Zokuthobela RoHS
Imithetho ye-RoHS isiza ukugcina indawo ephephile. Bakhawulela izinto eziyingozi ezifana nomthofu, i-mercury, ne-cadmium. Lokhu kuvimbela lobu buthi ekungcoliseni inhlabathi namanzi. Ukusebenzisa i-RoHS PCB kusho udoti omncane onobuthi ezindaweni zokulahla. Lokhu kuvikela imvelo futhi kugcina izilwane ziphephile ekulimaleni.
Imikhiqizo ye-RoHS nayo yenza ukugaywa kabusha kuphephe. Ama-elekthronikhi angalimaza izisebenzi ngesikhathi zigaywa kabusha uma zinezingxenye ezinobuthi. Ngokulandela imithetho ye-RoHS, izinkampani zenza imikhiqizo iphephe kakhudlwana ukuphatha. Lokhu kwehlisa ubungozi bezempilo kubasebenzi kanye nemiphakathi eseduze.
Ama-PCB Angenamthofu Ayehlisa Kanjani Imfucuza Enobuthi
Ama-PCB angenawo umthofu asiza ekwehliseni ukungcola okunobuthi. Ama-PCB amadala anesolder yomthofu angakhulula izinhlayiya eziyingozi. Ama-PCB angenawo umthofu asebenzisa izinsimbi eziphephile njengethini, isiliva, nethusi.
Ukukhetha ama-PCB angenawo umthofu kusiza ukumisa umthofu ekungcoliseni inhlabathi namanzi. Umthofu uyingozi kubantu nasezilwaneni. Lawa ma-PCB aphinde asekele imizamo yomhlaba wonke yokunciphisa i-e-waste. Ziyikhethelo eliluhlaza ekukhiqizeni kwesimanje.
Amazinga Omhlaba Nemithethonqubo Engaphezu Kwe-RoHS
I-RoHS ingumthetho obalulekile, kodwa akuwona wodwa. I-WEEE Directive in Europe igxile ekugayweni kabusha kwezinto zikagesi. E-US, i-RoHS 2 yengeza imithetho eqinile yokuphepha ku-RoHS yasekuqaleni.
Amazwe afana neJapan neChina anemithetho yawo ye-RoHS. Le mizamo yomhlaba wonke ihlose ukunciphisa izinto ezinobuthi yonke indawo. Ukusebenzisa i-RoHS noma ama-PCB angenamthofu kusiza ukuhlangabezana nalawa mazinga. Futhi kwenza imikhiqizo yakho ibe lula ukuyithengisa emhlabeni wonke.
Ukuqhathanisa Kwezobuchwepheshe: Izinto zokwakha kanye Nokukhiqiza
Ukwakheka Okubalulekile kwe-RoHS PCBs
Ama-PCB e-RoHS enziwe ngezinto eziphephile. Bagwema izinto eziyingozi ezifana nomthofu, i-mercury, i-cadmium, ne-hexavalent chromium. Izinsimbi eziphephile njengethayela, isiliva, nethusi zithatha indawo yalezi zinto ezinobuthi. Lokhu kusiza ama-PCB e-RoHS ukuthi ahlangabezane nemithetho yomhlaba wonke yokunciphisa ukungcola.
Lawa ma-PCB aphinde aklanyelwe ukuthi aphinde agaywe kabusha. Ukusebenzisa izingxenye ezingenabo ubuthi kwenza ukugaywa kabusha kube lula futhi kuphephe. Izimboni ezikhathalela imvelo zivame ukukhetha ama-RoHS PCB.
Ukwakheka Okubalulekile kwama-PCB Angenamthofu
Ama-PCB angenamthofu akhiwe ngaphandle kokusebenzisa umthofu. Kunalokho basebenzisa i-solder eyenziwe ngethayela, isiliva nethusi. Lezi zinsimbi zisebenza kahle ekuqhubeni ugesi nokuhlala ziqinile.
Ama-PCB angenawo umthofu angenza ngendlela ehlukile ngaphansi kwengcindezi. Isibonelo, i-solder yabo ingaphuka kalula ekushiseni okukhulu noma kubanda. Ngisho nalezi zinselelo, ama-PCB angenawo umthofu angcono kwezempilo kanye neplanethi.
Soldering Amazinga Okushisa Nezinqubo
Ukwenza i-RoHS nama-PCB angenawo umthofu kudinga amazinga okushisa aphezulu okushisa. Isoda engenamthofu incibilika cishe ku-422°F, kuyilapho isolder eliholayo lincibilika ku-361°F. Lokhu kushintsha indlela abakhiqizi abakha ngayo la ma-PCB.
Geza kabusha Izilungiselelo Zehhavini: Amahhavini agelezayo kufanele alungiselwe amazinga okushisa aphezulu. Izilungiselelo ezicophelelayo zivimbela ukulimala ezingxenyeni ezithambile.
Izindlela Zokuvikela Ukushisa: Ukushisa kuqala nokupholisa kancane kuvikela izingxenye emonakalweni wokushisa. Lezi zinyathelo zigcina i-PCB iqinile ngesikhathi sokuhlanganisa.
Amapulani Wokuhlanganisa: Ukulungisa amazinga erempu, ukushisa okuphezulu, nezikhathi zokupholisa kuqinisekisa imiphumela emihle. Lezi zinguquko zihambisana nezidingo ze-solder engenamthofu.
Ithebula elingezansi liqhathanisa ukusebenza kwe-solder eholayo nengenayo umthofu:
Isimo Sokuhlola | I-Lead Solder | I-Lead-Free Solder | Izici ezibalulekile |
|---|---|---|---|
Ukwehla kwezinga lokushisa kwegumbi | Fair | Kuhle kuya kokuhle | I-solder engenamthofu inamandla ezingeni lokushisa legumbi |
Ukwehla kwezinga lokushisa | Good | Fair | I-solder engenamthofu iba buthakathaka ekushiseni okuphezulu |
