Cov ntawv pov thawj xws li ISO 9001 lossis IPC-6012 yog cov cim zoo ntawm cov chaw tsim khoom cog lus rau qhov zoo.
Manufacturing Peev Xwm:Ntsuam xyuas lub chaw tsim khoom tsim muaj peev xwm ua tau raws li koj cov kev xav tau tshwj xeeb. Xav txog tej yam xws li kev tsim muaj peev xwm, kev muaj peev xwm, thiab kev muaj peev xwm los tswj cov qauv tsim los yog cov sij hawm nruj. Kev tsim muaj peev xwm txaus yog qhov tseem ceeb los xyuas kom meej cov khoom xa tuaj raws sij hawm thiab kev tsim khoom zoo ib yam.
Ntawv pov thawj thiab ua raws:Nrhiav cov tuam txhab lag luam uas ua tau raws li cov qauv kev lag luam kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm ENIG PCBs. Cov ntawv pov thawj xws li kev ua raws li RoHS (Kev txwv tsis pub muaj phom sij) qhia tau tias peb ua raws li cov cai ntawm ib puag ncig. Lwm cov ntawv pov thawj cuam tshuam yuav suav nrog ISO 14001 (kev tswj hwm ib puag ncig), ISO 13485 (cov khoom siv kho mob) lossis AS9100 (aerospace).
Cov neeg siv khoom xyuas thiab cov lus pov thawj:Nyeem cov neeg siv khoom xyuas thiab cov lus pov thawj rau cov chaw tsim khoom lub koob npe nrov thiab cov neeg siv khoom txaus siab. Nrhiav kev tawm tswv yim los ntawm lwm cov lag luam lossis cov kws tshaj lij uas lawv tau ua haujlwm nrog. Kev tshuaj xyuas zoo thiab cov lus pov thawj qhia tias muaj feem ntau dua ntawm kev paub zoo nrog cov chaw tsim khoom.
Kev sib txuas lus thiab Kev Pab Txhawb Cov Neeg Siv Khoom:Ntsuam xyuas lub chaw tsim khoom kev sib txuas lus thiab kev txhawb nqa cov neeg siv khoom. Kom meej meej, kev sib txuas lus raws sij hawm yog qhov tseem ceeb los xyuas kom meej tias koj cov lus thov raug nkag siab thiab ua tiav. Ntsuam xyuas lawv qhov kev teb, txaus siab los daws cov kev txhawj xeeb lossis teeb meem, thiab lawv lub peev xwm los muab kev txhawb nqa yog tias xav tau.
Nqi thiab Nqe:Txawm hais tias tus nqi yuav tsum tsis yog qhov kev txiav txim siab nkaus xwb, nws tseem ceeb heev uas yuav tsum xav txog tus nqi ntawm cov chaw tsim khoom. Tau txais quotes los ntawm ntau lub tuam txhab thiab sib piv lawv. Nco ntsoov tias tus nqi yuav tsum ua raws li qhov zoo thiab kev pabcuam. Cov neeg tsim khoom tuaj yeem cuam tshuam txog qhov zoo los ntawm kev muab cov nqi qis dua.
Los xaus,ENIG PCB muaj ntau yam zoo thiab siv dav hauv kev lag luam hluav taws xob. Lawv muab kev sib txuas zoo ntawm cov xaim hlau, solderability, thiab corrosion kuj, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob zoo. ENIG PCBs kuj muab qhov chaw tiaj tus, kom ntseeg tau qhov kev tso kawm raug thiab kev sib txuas txhim khu kev qha. Txawm hais tias koj tab tom tsim cov khoom siv hluav taws xob rau cov neeg siv khoom siv hluav taws xob, kev sib txuas lus, khoom siv kho mob lossis kev siv tsheb, xaiv ENIG PCB ua kom zoo thiab txhim khu kev qha.
Yog li ntawd, kuv xav kom koj xaiv ENIG PCB rau koj cov khoom siv hluav taws xob. Saib rau cov chaw tsim khoom lag luam lossis cov chaw muag khoom uas tshwj xeeb hauv ENIG PCB ntau lawm thiab muaj cov ntaub ntawv pov thawj ntawm kev xa cov khoom zoo. Nrog 15 xyoo ntawm kev paub txog engineering circuit boards,Capeltau ua tiav kev daws teeb meem enig circuit board rau ntau txhiab tus neeg siv khoom. Cov kev txawj tshaj lij thiab kev pabcuam sai ntawm peb pab pawg kws tshaj lij tau txais kev ntseeg siab ntawm cov neeg siv khoom los ntawm ntau dua 250 lub teb chaws. Los ntawm kev koom tes nrog Capel siv ENIG PCB tsim los ntawm Capel, koj tuaj yeem paub tseeb tias koj cov khoom siv hluav taws xob tau tsim los rau cov qauv siab tshaj plaws nrog kev ruaj ntseg zoo heev thiab zoo heev solderability. Yog li xaiv Capel ENIG PCB rau koj qhov project electronics tom ntej yog qhov kev xaiv zoo.
