Ukusebenza okuPhakamileyo:Ngeemoto zanamhlanje ezisanda kusebenzisa iinkqubo zombane eziphucukileyo, ukusebenza kwamaza ombane aphezulu kubaluleke kakhulu kuthungelwano oluchanekileyo. Ii-PCB ze-ENIG zineempawu ezibalaseleyo ze-frequency ephezulu yokuhanjiswa komqondiso othembekileyo kwizicelo ezinjengeenkqubo zoncedo lwabaqhubi abaphambili (ADAS), iinkqubo ze-infotainment, kunye neemodyuli zonxibelelwano.

Ukusebenza kobushushu:Ukusetyenziswa kweemoto kubandakanya iinjini kunye namanye amacandelo avelisa ubushushu obuninzi. I-ENIG PCB ine-conductivity efanelekileyo ye-thermal, eyenza ukuba ikhuphe ubushushu ngokufanelekileyo kwaye ithintele amacandelo e-elektroniki ekugqithiseni. Esi sikhundla solawulo lwe-thermal sinceda ukuphucula ukusebenza ngokubanzi kunye nokuthembeka kwenkqubo yombane yesithuthi.

5. Ungakhetha njani umenzi wePCB yobunjineli obufanelekileyo:

Xa ukhetha umenzi wePCB yobunjineli, kukho izinto ezininzi ekufuneka uziqwalasele ukuqinisekisa ukuba ukhetha umenzi ochanekileyo. Nazi iingongoma ezibalulekileyo ekufuneka uzikhumbule:

Amava kunye nobuGcisa:Khangela umenzi onamava abanzi kunye nobuchule ekuveliseni iiPCB ze-ENIG. Qwalasela ukuba banexesha elingakanani bekushishino nokuba banawo amava athile okwenza iiPCB zezicelo zobunjineli. Abavelisi abanerekhodi eqinisekisiweyo banokunikezela ngeemveliso ezisemgangathweni.

Imilinganiselo yoLawulo loMgangatho:Jonga ukuba ngaba umenzi uye wamisela amanyathelo angqongqo olawulo lomgangatho ukuqinisekisa ukuveliswa kweePCB zegolide ezintywiliselwa ezikumgangatho ophezulu. Kufuneka babe neenkqubo ezingqongqo zokuqinisekisa umgangatho kubandakanywa nokuhlolwa, uvavanyo kunye namaxwebhu. Izatifikethi ezifana ne-ISO 9001 okanye i-IPC-6012 zizalathisi ezilungileyo zokuzibophelela komenzi kumgangatho.

Ubunakho bokuVelisa:Vavanya amandla okwenza umenzi ukuhlangabezana neemfuno zakho ezithile. Qwalasela izinto ezifana nomthamo wemveliso, amandla obugcisa, kunye nokukwazi ukuphatha uyilo oluntsonkothileyo okanye amaxesha amisiweyo. Umthamo owaneleyo wokuvelisa uyimfuneko ukuze kuqinisekiswe ukuhanjiswa kwangexesha kunye nomgangatho wemveliso ongaguqukiyo.

Izatifikethi kunye nokuThobela:Fumana abavelisi abahlangabezana nemigangatho yoshishino ukuqinisekisa umgangatho kunye nokuthembeka kwe-ENIG PCBs. Izatifikethi ezifana nokuthotyelwa kwe-RoHS (Ukuthintelwa kwezinto ezinobungozi) kubonisa ukuthobela kwethu imigaqo yokusingqongileyo. Ezinye iziqinisekiso ezifanelekileyo zinokubandakanya i-ISO 14001 (iinkqubo zolawulo lokusingqongileyo), ISO 13485 (izixhobo zonyango) okanye i-AS9100 (i-aerospace).

Uphononongo lwabathengi kunye nobungqina:Funda uphononongo lwabathengi kunye nobungqina begama lomenzi kunye nokwaneliseka kwabathengi. Funa impendulo kwamanye amashishini okanye iingcali osebenze nazo. Uphononongo oluhle kunye nobungqina bubonisa ukuba nokwenzeka okuphezulu kwamava alungileyo kunye nomenzi.

Unxibelelwano kunye neNkxaso yabaThengi:Ivavanya unxibelelwano lomenzi kunye nenkxaso yenkxaso yabathengi. Unxibelelwano olucacileyo, olungexesha lubalulekile ukuqinisekisa ukuba izicelo zakho ziyaqondwa kwaye ziyafezekiswa. Ukuvavanya ukuphendula kwabo, ukuzimisela ukujongana nayo nayiphi na inkxalabo okanye imiba, kunye nokukwazi kwabo ukubonelela ngenkxaso yobugcisa xa kuyimfuneko.

Iindleko kunye neXabiso:Ngelixa iindleko akufanele zibe yiyo kuphela into emiselayo, kubalulekile ukuqwalasela amaxabiso eenkonzo zomenzi. Fumana iikowuti kubavelisi abaninzi kwaye uzithelekise. Khumbula ukuba amaxabiso kufuneka ahambelane nomgangatho kunye nenkonzo enikezelwayo. Abavelisi banokubeka esichengeni umgangatho ngokunikezela ngamaxabiso aphantsi kakhulu.

Ukushwankathela,I-ENIG PCB ineengenelo ezininzi kwaye isetyenziswa kakhulu kushishino lombane. Babonelela ngokugqwesa ukudityaniswa kocingo, ukuthengiseka, kunye nokuxhathisa umhlwa, kubenza balungele ukusebenza okuphezulu kwe-elektroniki. IiPCB ze-ENIG zikwabonelela ngomphezulu othe tyaba, ukuqinisekisa ukubekwa kwecandelo elichanekileyo kunye noqhagamshelo oluthembekileyo. Nokuba uyila i-electronics kubathengi be-elektroniki, unxibelelwano, izixhobo zonyango okanye usetyenziso lweemoto, ukukhetha i-ENIG PCB iqinisekisa umgangatho ophezulu kunye nokusebenza okuthembekileyo.

Ke ngoko, ndiyakukhuthaza ukuba ukhethe i-ENIG PCB kwiimfuno zakho zokwenza i-elektroniki. Jonga umenzi othembekileyo okanye umthengisi ogxile kwimveliso ye-ENIG PCB kwaye unerekhodi eqinisekisiweyo yokuhambisa iimveliso ezikumgangatho ophezulu. Ngeminyaka eyi-15 yamava eebhodi zeesekethe zobunjineli,eKapaiye yayisombulula ngempumelelo imingeni yebhodi yesekethe enig kumawaka abathengi. Izakhono zobuchwephesha kunye nenkonzo yokuphendula ngokukhawuleza yeqela lethu leengcali lizuze ukuthenjwa ngabathengi abavela kumazwe angaphezu kwama-250. Ngokubambisana neCapel ukusebenzisa i-ENIG PCB eyenziwe nguCapel, unokuqiniseka ukuba i-electronics yakho yenziwe ngeyona migangatho iphezulu kunye nokuqina okugqwesileyo kocingo kunye nokuthengiswa okugqwesileyo. Ke ukukhetha iCapel ENIG PCB kwiprojekthi yakho elandelayo ye-elektroniki lukhetho olufanelekileyo.
