Lezi zinhlaka zokuthobela imithetho zenzelwe ukuvikela abathengi ekushaqekeni kukagesi, ezingozini zomlilo, ukuphazamiseka kukagesi, kanye nokuvezwa kwamakhemikhali anobuthi. Ochwepheshe bokuthenga kumele baphathe lezi zitifiketi hhayi njengemicabango yangemva kokukhiqiza, kodwa njengemininingwane ephoqelekile efakwe ngaphakathi kwesicelo sokuqala se-Quotation (RFQ).

Izindlela zomthetho ze-EU kanye ne-US zisebenza ngamafilosofi ahlukene ezomthetho kanye nemingcele yezobuchwepheshe, kodwa zombili zidinga imibhalo eqinile. Ukuqonda okuyisisekelo kwalezi ziqondiso kuvumela amaqembu okuthenga ukuthi ahlole ngokunembile amakhono abaphakeli, ahlunge abathengisi abangathobeli imithetho ekuqaleni kwenqubo yokuthola impahla, futhi abikezele ngokunembile izindleko eziphelele zezimpahla ezifike.

Izibopho ze-CE, RoHS, REACH, WEEE, kanye nokupakisha

I-European Union iyala ukulandelwa okuqinile kwemiyalelo eminingi ngaphambi kokuba umkhiqizo ube nophawu lwe-CE ngokusemthethweni. Kumalambu e-USB, lokhu kuhilela kakhulu i-Electromagnetic Compatibility (EMC) Directive (2014/30/EU), ukuqinisekisa ukuthi idivayisi ayikhiphi ukuphazamiseka okukhulu kwe-electromagnetic futhi ayithinteki ngokungafanele yiyo. Ngenkathi amadivayisi e-USB ane-voltage ephansi (ngokuvamile asebenza ku-5V) evame ukuwela ngaphandle kobubanzi be-Low Voltage Directive (LVD) eyinhloko, i-General Product Safety Directive (GPSD) isasebenzisa ukuphepha kukagesi okuyisisekelo, ivame ukubhekisela ezindinganisweni ze-EN 62368-1 zamabhethri ahlanganisiwe kanye namasekethe okushaja.

Ukuthobela amakhemikhali kanye nemvelo e-EU kuqinile ngokulinganayo. I-RoHS 3 Directive ikhawulela izinto eziyingozi eziyishumi, okuhlanganisa nokuphoqelela inani eliphakeme kakhulu lokuhlushwa elingu-0.1% ngesisindo (1,000 ppm) le-lead, i-mercury, kanye nama-phthalates athile ezintweni ezihambisanayo. Ngesikhathi esifanayo, umthethonqubo we-REACH udinga ukuqapha okuqhubekayo kwe-Substances of Very High Concern (SVHCs), uhlu oludlula amakhemikhali angu-240 okwamanje. Okokugcina, abangenisi kumele bahambisane ne-WEEE Directive yokubuyisa imfucuza kagesi kanye ne-Packaging Directives yendawo, ebeka iminikelo yokuvuselela kabusha kanye nezidingo ezithile zokulebula (njenge-logo ye-Triman eFrance) ngokusekelwe ku-tonnage yezinto ezibekwe emakethe.

Izindlela ze-FCC, UL noma ETL, kanye nokucatshangelwa kwe-CPSIA

E-United States, ukwengamela imithetho kuhlukaniswe phakathi kwezikhungo zikahulumeni, imithetho yesifundazwe, kanye nezindinganiso zemboni eziphoqelelwe. Ezingeni likahulumeni, i-Federal Communications Commission (FCC) isebenzisa imithethonqubo ye-Part 15 Subpart B, edinga ukuhlolwa ukuqinisekisa ukuthi ukujikeleza kwesibani sekhanda akubangeli ukuphazamiseka okulimazayo kwemvamisa yomsakazo. Ngenkathi i-US ingenayo imodeli yokuziqinisekisa yophawu lwe-CE yokuphepha okujwayelekile, imakethe ithembele kakhulu kumaLaboratories Okuhlola Aqashelwa Kuzwelonke (ama-NRTL) afana ne-UL, ETL, noma i-CSA ukuze kuncishiswe umthwalo wemfanelo.

Kumalambu e-USB, ukuthola isitifiketi se-UL 1598 (Luminaires) noma i-UL 62368-1 (Audio/Video, Information and Communication Technology Equipment) kunikeza ukuzivikela okuqinile ezimangalweni zomthwalo wemfanelo womkhiqizo. Ngaphezu kwalokho, ukuphepha kwebhethri le-lithium-ion kulawulwa yizindinganiso ze-UL 2054 kanye ne-UL 1642. Uma isibani sekhanda sithengiswa noma sifinyeleleka kalula ezinganeni ezingaphansi kweminyaka engu-12, siwela ngaphansi komthetho we-Consumer Product Safety Improvement Act (CPSIA), okhawulela ngokuqinile i-surface coating lead ku-90 ppm kanye ne-total substrate lead ku-100 ppm, okudinga ukuhlolwa yilabhorethri eyamukelwa yi-CPSC.

Ukuhlolwa kwezitifiketi zamaqembu okuthenga

Ukuze lezi zidingo zisebenze, amaqembu okuthenga kumele asebenzise imephu yesitifiketi ehlelekile. Le ndlela ivumelanisa imakethe eqondiwe nezinqubo zokuhlola ezidingekayo, iqinisekisa ukuthi azikho izindawo ezingabonakali zomthetho ngaphambi kokuba kuqale ukusetshenziswa kwamathuluzi nokukhiqiza. Ithebula elilandelayo linikeza ukuhlukaniswa okuqhathanisayo kwezidingo eziyinhloko kuzo zombili izindawo.

Ukuphepha kwebhethri, ukwakheka kokushaja, kanye nokulawulwa kwekhwalithi yefektri

Amabhethri e-Lithium-ion kanye ne-lithium-polymer ahlinzeka ngamandla adingekayo ukuze anikeze amandla ama-LED asebenza kahle kakhulu, kodwa futhi aletha izingozi ezinkulu zokushisa kanye namakhemikhali uma zingaphathwanga kahle. Ngenxa yalokho, ukuqinisekiswa kobunjiniyela kokuphepha kwebhethri kanye nomklamo wokushaja kuyisigaba esibaluleke kakhulu sokufaneleka komkhiqizo.

Ukulawulwa kwekhwalithi ezingeni lefektri kumele kuguquke kusuka ekuhlolweni okubonakalayo okubonakalayo kuye ekulinganisweni okuqondile, okuqhutshwa idatha. Amaqembu okuthenga kumele agunyaze amaphuzu athile okuhlola kanye nokubekezelelana okwamukelekayo ezivumelwaneni zawo zabahlinzeki, aqinisekise ukuthi yonke inqwaba yokukhiqiza inamathela ngokuqinile kumapharamitha okusebenza esampula yegolide evunyiwe.

Izincazelo zobuchwepheshe ezibalulekile kanye namaphuzu okuhlola

Imininingwane yobuchwepheshe kumele ichazwe ngokucacile kwinkontileka yokuthenga ukuze kugwenywe ukungaqondakali. Kumasekethe okushaja i-lithium-ion, amaphuzu okuhlola abalulekile ajikeleza ekulawulweni kwe-voltage. Umkhawulo wokuvikela ukushaja ngokweqile kumele ulinganiswe ngokuqinile; kwiseli ejwayelekile ye-lithium engu-3.7V, i-IC yokushaja kumele iqede ugesi ku-4.25V ± 0.05V. Ukudlula lo mkhawulo kwandisa kakhulu ingozi yokuqhekeka kwe-lithium kanye nokubaleka kokushisa okulandelayo. Ngokuphambene nalokho, ukunqanyulwa kokukhipha ngokweqile kufanele kubekwe ngaphansi kuka-2.75V ukuvimbela ukuwohloka kwamandla okungenakuguqulwa.

Ukuqina ngokomzimba kanye nokumelana nemvelo nakho kudinga amaphuzu okuhlola angalinganiswa. Ukuhlolwa kokuwa kufanele kwenziwe kusukela ekuphakameni kwamamitha angu-1.5 kuya kwangu-2.0 phezu kokhonkolo, kuthinte ama-axes amaningi ukuqinisekisa ubuqotho besakhiwo kanye nokuvinjelwa kwebhethri. Ukuze kuvikelwe imvelo, isilinganiso se-Ingress Protection (IP) kumele siqinisekiswe ngokuhlolwa okujwayelekile. Isilinganiso se-IPX4 sidinga ukuvikelwa emanzini agelezayo avela kunoma iyiphi indlela imizuzu emi-5, kuyilapho isilinganiso se-IP68 sidinga ukucwiliswa njalo emanzini angaphezu kwemitha eli-1 ukujula, okudinga ama-compounds athile okubumba kanye nokubekezelelana kwe-silicone O-ring.

Ukuhlolwa kwebhethri okuhlanganisiwe uma kuqhathaniswa nokungashintshwa

Amaqembu okuthenga abhekene nesinqumo esibalulekile sokwakha phakathi kwamaphakethe ebhethri ahlanganisiwe (avaliwe) kanye nokulungiselelwa kwamaseli angashintshwa ngumsebenzisi. Imiklamo ehlanganisiwe, evame ukusebenzisa amaphakethe e-lithium-polymer angokwezifiso, ivumela izibani zekhanda eziqinile nezilinganiswe kahle kanye nokuvikela amanzi okungcono kakhulu. Kodwa-ke, ikhwalithi yeseli yangaphakathi ibaluleke kakhulu, njengoba ukuwohloka kwangaphambi kwesikhathi kwenza yonke idivayisi ingasebenzi. Izindinganiso zokuthenga zamabhethri ahlanganisiwe kufanele zifune impilo yomjikelezo okungenani imijikelezo yokushaja/yokukhipha engu-500 ngaphambi kokuba umthamo wehle ngaphansi kuka-80% wesilinganiso sawo sokuqala.

Imiklamo yebhethri engashintshaniswa, evame ukusebenzisa amaseli ajwayelekile angu-18650 noma angu-21700 cylindrical, inikeza usizo olude lomsebenzi wasensimini kanye nokuvuselelwa kabusha kokuphela kokuphila okulula. Ukugxila kokuqinisekiswa kwekhwalithi lapha kushintshela kokuxhumana okwenziwa ngomshini kanye nobuqotho besakhiwo sendawo yebhethri. Ukuxhumana kwe-dual-spring okunegolide noma i-nickel plating ejiyile kuyadingeka ukuvimbela i-micro-arcing nokugcina ukuxhumana ngesikhathi sokudlidliza okukhulu. Ngaphezu kwalokho, ukujikeleza kwangaphakathi kwesibani sekhanda kumele kufake ukuvikelwa kwe-reverse polarity ukuvimbela ukujikeleza okufushane okubi uma umsebenzisi wokugcina efaka ibhethri ngendlela engafanele.

Ukuqinisekiswa kwefektri, ukuhlolwa kwangaphambi kokuthunyelwa, kanye nokulawulwa kwedokhumenti

Umklamo womkhiqizo oqine kakhulu ungaphazamiseka ngenxa yokwenziwa kabi kokukhiqiza, okwenza ukuqinisekiswa kwefektri kube yisigaba esibalulekile sokuthenga. Ngaphambi kokuba kuqale ukukhiqizwa ngobuningi, izinqubo zokulawula ikhwalithi yangaphakathi yefektri kumele zihlolwe. Lokhu kuhlanganisa ukuqinisekisa ukulinganiswa kwama-sphere azo ahlanganisayo ukuze kulinganiswe ukuphuma kwe-lumen nokuqinisekisa ukuthi anamakhabethe okuguga ebhethri azenzakalelayo ukuqinisekisa ukusebenza kweseli ngaphansi kokucindezeleka kokushisa.

Ukuhlolwa kwangaphambi kokuthunyelwa kumele kulandele amazinga okuhlola izibalo aqashelwa emhlabeni wonke, ngokuvamile i-ANSI/ASQ Z1.4. Iphrofayili yokuhlola eqinile ejwayelekile isebenzisa i-General Inspection Level II, ene-Acceptable Quality Limits (AQL) ebekwe ku-0 kumaphutha abucayi (isb., ama-shorts kagesi, izintambo eziveziwe), u-1.5 kumaphutha amakhulu (isb., ama-LED angasebenzi, ukushaja okuhlulekile), kanye no-4.0 kumaphutha amancane (isb., imihuzuko emincane yobuhle). Ngaphezu kwalokho, umhlinzeki kumele agcine ukulawula okuqinile kwamadokhumenti, anikeze imiphumela yokuhlola ephelele yokushiswa ngaphakathi—njengokusebenzisa izibani zekhanda ekuphumeni okungu-100% amahora angama-24 kuya kwangu-48 ekushiseni okumaphakathi okungu-45°C—ukuze kutholakale ukwehluleka kwe-elekthronikhi kwasekuqaleni ngaphambi kokuba izimpahla zifakwe ebhodleleni.

Iziqu zomhlinzeki, imibhalo, kanye nokuhambisana nemithetho yezokuthutha

Ukushintsha kusuka ekwakhiweni komkhiqizo kuya ekukhiqizweni okukhulu kudinga ukuhlolwa okujulile komlingani wokukhiqiza. Iziqu zomhlinzeki akuyona nje into yokwenza amanani; kuwukuhlolwa kokuvuthwa kwenhlangano yomthengisi, ukulawulwa kwenqubo, kanye nekhono lokwenza njalo izidingo zokuthobela imithetho eziyinkimbinkimbi. Ukwehluleka komhlinzeki ukugcina lezi zindinganiso kungabangela ukuthunyelwa okulibazisekile, izimpahla ezithathwe emasimini, noma ukwehluleka okukhulu kwensimu.

Okubaluleke ngokulinganayo ukuphathwa kwempahla kanye nemibhalo. Ukuthuthwa kwezimpahla kwamanye amazwe okuqukethe amabhethri e-lithium-ion kulawulwa kakhulu yiziphathimandla zezindiza zomhlaba wonke kanye nezasolwandle. Amaqembu okuthenga kumele aqinisekise ukuthi umhlinzeki ofanelekayo unekhono elikhulu ekukhiqizeni amaphepha okuthobela imithetho adingekayo kanye nokunamathela ezimisweni zokupakisha eziqinile ukuze kube lula ukuthutha okuhambayo ngaphandle kokuphazamiseka.

Izindlela zokugunyazwa komhlinzeki kanye nekhono lokuhlola

Ukuvunyelwa komhlinzeki kufanele kuncike ekuzibophezeleni okubonakalayo ekuphathweni kwekhwalithi, okuvame ukubonakala ngesitifiketi se-ISO 9001:2015 esivela kumbhalisi odumile. Ngaphandle kokuthobela imithetho eyisisekelo ye-ISO, amaqembu okuthenga kumele ahlole amakhono okuhlola angaphakathi efektri. Umkhiqizi wezibani ze-USB ofanelekayo kufanele abe nemishini edingekayo yokwenza ukuhlolwa okuzenzakalelayo kwe-PCBA okuzenzakalelayo (i-AOI) okuvamile, ukulinganisa umthamo webhethri, kanye nokuhlolwa kwegumbi lemvelo ngaphandle kokuthembela ngokuphelele kumalebhu eqembu lesithathu angaphandle.

Ukulungiswa kwezentengiselwano nakho kuyisici esibalulekile sokufaneleka. Abathengi kumele bahlole ukuthi i-Minimum Order Quantity (MOQ) yefektri iyahambisana yini nemingcele yekhwalithi edingekayo. Ukusebenzisa amaphrofayili e-QA enziwe ngokwezifiso, amathuluzi azinikele, kanye nokuthola izingxenye ezikhethekile ngokuvamile kudinga i-MOQ yamayunithi ayi-1,000 kuya ku-3,000. Abahlinzeki abanikeza ama-MOQ aphansi kakhulu ezimpahla "eziqinisekisiwe" bavame ukuthengisa imikhiqizo ethengiswa ngaphandle kwe-oda lapho umthengi engabonakali nhlobo ku-bill yezinto zangempela noma ukuhambisana kwezingxenye zangaphakathi.

Amadokhumenti adingekayo ngaphambi kokufakwa kwe-oda nokuthunyelwa

Ukuze kuncishiswe ubungozi, amaqembu okuthenga kumele aphoqelele isango eliqinile lamadokhumenti. Akukho myalelo wokuthenga okufanele uqedwe ngaphandle kwe-Bill of Materials (BOM) enemininingwane, ekhiyiwe echaza uhlobo oluqondile kanye nomodeli wezingxenye ezibalulekile, njenge-LED emitter (isb., i-Cree, i-Osram), i-IC yokushaja, kanye nomkhiqizi weseli le-lithium-ion othize. Lokhu kuvimbela umkhuba ovamile wemboni wokushintsha izingxenye ezingagunyaziwe ngesikhathi sokukhiqizwa ngobuningi, okungenza buthule izitifiketi zokuphepha ezitholwe ngaphambilini zingabi namsebenzi.

Ngaphambi kokukhishwa kokuthunyelwa kokugcina kanye nokugunyazwa kwenkokhelo yebhalansi, umhlinzeki kumele ahlinzeke ngephakethe eliphelele lamadokhumenti. Kokuthunyelwa kwamanye amazwe aseYurophu, lokhu kufaka phakathi iSimemezelo Sokuvumelana (i-DoC) esisemthethweni esisayinwe ngumkhiqizi, esichaza ngokucacile iziqondiso ezifanele kanye nezindinganiso ze-EN. Ngaphezu kwalokho, umthengi kumele aqinisekise umbiko wokuhlola we-UN38.3 kanye ne-Material Safety Data Sheet (MSDS) yemodeli ethile yebhethri esetshenziswe ekukhiqizeni, enosuku olungaphakathi konyaka wekhalenda wamanje, ukuze kuhlangatshezwane nezidingo zamasiko nezokuthutha impahla.

Imithetho yokuthutha ibhethri, ukulebula, kanye nokuqina kokupakisha

Ukuhamba okungokoqobo kwezibani ze-USB kulawulwa yimithetho eqinile yezimpahla eziyingozi ngenxa yemithombo yazo yamandla e-lithium-ion. Ngokuphathelene nokuthunyelwa kwezimpahla emoyeni, i-International Air Transport Association (IATA) iphoqelela imithetho eqinile mayelana ne-State of Charge (SoC) yebhethri. Amabhethri kumele athunyelwe nge-SoC engaphansi kuka-30% wekhono lawo elilinganiselwe ukuze kuncishiswe ingozi yokubaleka kokushisa ngesikhathi sokundiza. Ukupakisha kumele futhi kubekezelele ukuhlolwa okuthile kokuwa futhi kusetshenziswe amabhokisi angaphandle aqinile ukuvimbela ukuchotshozwa noma ukubhobozwa.

Uhlaka lwesinqumo sokuthengwa kwempahla sokuqinisekisa ikhwalithi kanye nesitifiketi

Ochwepheshe bokuthenga kumele bahlanganise iziqondiso zomthetho, idatha yokulawula ikhwalithi, kanye namaqiniso ebhizinisi abe uhlaka oluhambisanayo lokwenza izinqumo. Inhloso ukulinganisela izindleko zangaphambilini zesitifiketi esiqinile kanye nokuqinisekiswa kwekhwalithi ngokumelene nezingozi zezimali zesikhathi eside zokungalandeli imithetho kanye nokwehluleka komkhiqizo. Lolu hlaka ludinga incazelo ecacile phakathi kwalokho okugunyazwe ngokomthetho, lokho okudingwa ngabalingani bezitolo, kanye nalokho okumelela ukutshalwa kwezimali okunesu ekulinganisweni komkhiqizo.

Ekugcineni, izinga lokutshalwa kwezimali okuqinisekiswa kwekhwalithi kufanele lihambisane nokuma kwemakethe yomkhiqizo kanye nokubekezelelana kwengozi kwenkampani engenisa impahla. Ukuphatha ukuthobela imithetho njengesikali esishintshayo kunokuba kube ibhokisi lokuhlola eliyindilinga kuvumela amaqembu okuthenga ukuthi abele izinsiza ngendlela efanele, aqinisekise ukuthi ama-SKU anobungozi obukhulu, athola izinga eliphezulu lokuhlolwa ngenkathi egcina amanani ancintisanayo.

Ukubeka phambili izitifiketi ezidingekayo kanye nezidingo zomthengisi

Isigaba sokuqala sohlaka lwesinqumo sokuthengwa kwempahla sihilela ukubeka phambili izitifiketi zomthetho eziphoqelekile. E-EU, ukwehluleka ukunikeza amadokhumenti e-CE asebenzayo (ahlanganisa i-EMC kanye ne-RoHS okungenani) kungabangela ukushajwa kwentela ngokushesha kanye nezinhlawulo zokungalandeli imithetho ezingakhuphukela ku-€50,000 ngokwephulwa ngakunye kuye ngokuthi yiliphi izwe eliyilungu. Lezi zitifiketi eziyisisekelo azixoxiswani futhi kumele zifakwe kuhlu lwesikhathi sokuqala sokuthola impahla, njengoba ukuhlolwa kwelebhu yomuntu wesithathu kungangeza amasonto amathathu kuya kwayisithupha emjikelezweni wokuthengwa kwempahla.

Ngaphandle kwemithetho, izidingo zesiteshi sokuthengisa zivame ukunquma izinga eliphakeme lobufakazi. Amapulatifomu amakhulu e-e-commerce, njenge-Amazon, manje asebenzisa izinqubomgomo zokuphepha zamadivayisi asebenzisa i-lithium-ion. Ukuzama ukufaka isibani sekhanda se-USB ngaphandle kokuthumela imibiko yokuhlola ye-UL 2054 noma i-IEC 62133 eqinisekisiwe evela elabhorethri egunyaziwe ye-ISO 17025 kuvame ukuphumela ekufakweni ohlwini okucindezelwe. Amaqembu okuthenga kumele ahlele amabhukwana athile okuthobela imithetho yabathengisi abaqondiwe ngaphambi kokuqedela imininingwane yomkhiqizo nomhlinzeki waphesheya kwezilwandle.

Uma ukutshalwa kwezimali okuphezulu kwesitifiketi kusengaphambili kufanelekile

Kunezimo ezihlukile lapho ukutshala imali ezitifiketini zokuzithandela, eziphezulu kuveza imbuyiselo enamandla ekutshalweni kwezimali. Ukuphishekela isitifiketi se-NRTL esigcwele (njengophawu lwe-UL noma lwe-ETL) sesibani sekhanda esise-US kudinga izindleko ezinkulu zenhloko-ngokuvamile ukwengeza u-$3,000 kuya ku-$5,000 nge-SKU ngayinye ekuhlolweni nasekufakweni kwemali yokudala, kanye nezindleko zokuhlola zefektri eziqhubekayo zekota. Kodwa-ke, kumabhrendi angaphandle asezingeni lebhizinisi, ezimbonini, noma aphezulu, lokhu kutshalwa kwezimali kuvame ukuba nelungelo.

Uphawu lwe-NRTL oluqashelwayo luvula ngokushesha ukufinyelela kumaketanga okuthengisa angokoqobo e-Tier-1 agcina izinqubomgomo zokungabekezeleli nhlobo izinto zikagesi ezingaqinisekisiwe. Ngaphezu kwalokho, iminyango yokuthengwa kwezinkampani ngaphakathi kwemikhakha yezimayini, yokwakha, kanye nezinsiza idinga ngokuqinile la maki ukuze kulandelwe ukuphepha emsebenzini. Ngaphezu kwalokho, ukuba nezitifiketi zokuphepha eziphezulu kunganciphisa kakhulu amaphrimiyamu omshwalense wesikweletu somkhiqizo wenkampani—ngokuvamile okuholela ekunciphiseni okungu-15% kuya ku-20% ezindlekweni zenqubomgomo zonyaka—ngaleyo ndlela kususwe izindleko zokuhlola zokuqala esikhathini sokuphila komkhiqizo.

Izinto Ezibalulekile Okufanele Uzicabangele

• Iziphetho ezibaluleke kakhulu kanye nesizathu sokuqinisekiswa kwekhwalithi
• Imininingwane, ukuhambisana, kanye nokuhlolwa kwengozi okufanele kuqinisekiswe ngaphambi kokuthi uzibophezele
• Izinyathelo ezilandelayo ezisebenzayo kanye nezixwayiso abafundi abangazisebenzisa ngokushesha

imibuzo ejwayelekile ukubuzwa

Yiziphi izitifiketi ezivame ukudingeka kuma-headlamps e-USB athengiswa eYurophu?

Okungenani, hlola ukuhambisana ne-CE, izibopho ze-RoHS, i-REACH, kanye ne-WEEE, kanye nokuhambisana nokupakisha lapho kufanele khona. Cela iSimemezelo Sokuhambisana kanye nemibiko yokuhlola efanayo ngaphambi kokufaka ama-oda.

Yikuphi ukuthobela imithetho okufanele abathengi bakuqinisekise ngezibani ze-USB ezingena e-US?

Qinisekisa ukuhlolwa kokuphepha kukagesi okusebenzayo, izidingo ze-FCC zokuhambisana kwe-electromagnetic uma kufaneleka, kanye nokuhambisana nokuthuthwa kwebhethri. Cela imibiko yamanje yelebhu ehlobene nemodeli eqondile kanye nokucushwa kwebhethri.

Kungani ukuphepha kwebhethri kuyinkinga enkulu yokuqinisekisa ikhwalithi yezibani ze-USB?

Amaseli e-lithium-ion aphinde ashajwe angashisa ngokweqile, avuvuke, noma ahluleke uma amasekethe okushaja nokuvikela ebuthakathaka. Qinisekisa ukushaja ngokweqile, ukukhipha ngokweqile, kanye nokuvikelwa kokushisa kokubili ephaketheni lebhethri kanye ne-PCBA.

Yimaphi amadokhumenti okufanele amaqembu okuthenga aqoqe kubaphakeli?

Thola iSimemezelo Sokuhambisana, imibiko yokuhlolwa yomuntu wesithathu, uhlu lwezinto zokwakha, imininingwane yebhethri, idatha yokupakisha, kanye namarekhodi e-QC yasefektri. Qinisekisa ukuthi wonke amadokhumenti afana ne-SKU yokugcina, hhayi isampula efanayo.

Abathengi banganciphisa kanjani iwaranti kanye nengozi yokuyibuyisela emuva ngaphambi kokukhiqizwa ngobuningi?

Yenza ukuhlolwa kwangaphambi kokuthunyelwa, ukuhlolwa kokuthembeka, kanye nokuqinisekiswa kwesampula kumamodeli ane-lumen ephezulu. Setha imigomo yokukhubazeka ngaphansi kuka-1.5% futhi udinga izinyathelo zokulungisa ukwehluleka kokushisela, ukushaja, kanye nokungena komswakama.
