Cov Ntawv Nyiaj Tooj Liab ED Uas Muaj Kev Tiv Thaiv
Kev Taw Qhia Txog Khoom
Cov ntawv ci tooj liab STD uas tsim los ntawm CIVEN METAL tsis yog tsuas yog muaj kev ua hluav taws xob zoo vim yog qhov ntshiab ntawm tooj liab, tab sis kuj yooj yim rau kev txiav thiab tuaj yeem tiv thaiv cov teeb liab electromagnetic thiab microwave cuam tshuam. Cov txheej txheem tsim khoom electrolytic tso cai rau qhov dav tshaj plaws ntawm 1.2 meters lossis ntau dua, tso cai rau kev siv yooj yim hauv ntau qhov chaw. Cov ntawv ci tooj liab nws tus kheej muaj lub duab tiaj tus thiab tuaj yeem ua pwm zoo rau lwm cov ntaub ntawv. Cov ntawv ci tooj liab kuj tiv taus kev kub siab oxidation thiab corrosion, ua rau nws tsim nyog rau kev siv hauv qhov chaw hnyav lossis rau cov khoom nrog cov khoom siv nruj.
Cov Lus Qhia Tshwj Xeeb
CIVEN tuaj yeem muab 1/3oz-4oz (nominal thickness 12μm -140μm) shielding electrolytic copper foil nrog qhov dav tshaj plaws ntawm 1290mm, lossis ntau yam kev qhia ntawm shielding electrolytic copper foil nrog qhov tuab ntawm 12μm -140μm raws li cov neeg siv khoom xav tau nrog cov khoom zoo ua tau raws li cov kev cai ntawm IPC-4562 tus qauv II thiab III.
Kev ua tau zoo
Nws tsis yog tsuas yog muaj cov khoom zoo heev ntawm cov siv lead ua zoo sib npaug, qis profile, lub zog siab thiab elongation siab, tab sis kuj muaj cov dej noo zoo, tshuaj lom neeg tsis kam, thermal conductivity thiab UV tsis kam, thiab yog qhov tsim nyog rau kev tiv thaiv kev cuam tshuam nrog hluav taws xob zoo li qub thiab kev tswj hwm cov nthwv dej electromagnetic, thiab lwm yam.
Cov ntawv thov
Haum rau kev siv tsheb, hluav taws xob, kev sib txuas lus, tub rog, aerospace thiab lwm yam high-power circuit board, high-frequency board manufacturing, thiab transformers, cables, xov tooj ntawm tes, computers, kev kho mob, aerospace, tub rog thiab lwm yam khoom siv hluav taws xob tiv thaiv.
Cov txiaj ntsig
1 、 Vim yog cov txheej txheem tshwj xeeb ntawm peb qhov chaw roughening, nws tuaj yeem tiv thaiv kev puas tsuaj hluav taws xob.
2, Vim tias cov qauv noob ntawm peb cov khoom yog equiaxed zoo crystal spherical, nws luv lub sijhawm ntawm kab etching thiab txhim kho qhov teeb meem ntawm kab tsis sib xws sab etching.
3, thaum muaj lub zog tev tawv siab, tsis muaj kev hloov pauv hmoov tooj liab, cov duab meej ntawm PCB kev tsim khoom.
