Shielded ED Copper Foils
Khoom Taw Qhia
STD tus qauv tooj liab ntawv ua los ntawm CIVEN METAL tsis yog tsuas yog muaj hluav taws xob zoo vim tias muaj cov purity siab ntawm tooj liab, tab sis kuj yog ib qho yooj yim rau etch thiab tuaj yeem tiv thaiv electromagnetic signals thiab microwave cuam tshuam. Cov txheej txheem tsim hluav taws xob tso cai rau qhov dav siab tshaj plaws ntawm 1.2 meters lossis ntau dua, tso cai rau kev siv tau yooj yim hauv ntau thaj chaw. Cov ntawv ci tooj liab nws tus kheej muaj cov duab tiaj tus heev thiab tuaj yeem ua tau zoo molded rau lwm cov ntaub ntawv. Cov ntawv ci tooj liab kuj tseem tiv taus qhov kub thiab txias oxidation thiab corrosion, ua rau nws haum rau siv nyob rau hauv hnyav ib puag ncig los yog rau cov khoom uas nruj cov ntaub ntawv uas yuav tsum tau lub neej.
Specifications
CIVEN tuaj yeem muab 1/3oz-4oz (nominal thickness 12μm -140μm) shielding electrolytic copper foil nrog qhov siab tshaj plaws ntawm 1290mm, los yog ntau yam specifications ntawm shielding electrolytic tooj liab ntawv ci nrog ib tug tuab ntawm 12μm -140μm raws li cov neeg yuav tsum tau nrog cov khoom zoo raws li lub Cov kev cai ntawm IPC-4562 tus qauv II thiab III.
Kev ua tau zoo
Nws tsis tsuas yog muaj lub cev zoo ntawm equiaxial zoo siv lead ua, tsis tshua muaj profile, siab zog thiab siab elongation, tab sis kuj muaj cov dej noo zoo, tshuaj tiv thaiv, thermal conductivity thiab UV tsis kam, thiab tsim nyog rau kev tiv thaiv kev cuam tshuam nrog hluav taws xob zoo li qub thiab tiv thaiv electromagnetic. vuag, etc.
Daim ntawv thov
Haum rau tsheb, hluav taws xob hluav taws xob, kev sib txuas lus, tub rog, aerospace thiab lwm yam hluav taws xob hluav taws xob hluav taws xob hluav taws xob, kev tsim hluav taws xob ntau zaus, thiab kev hloov pauv, cables, xov tooj ntawm tes, khoos phis tawj, kho mob, aerospace, tub rog thiab lwm yam khoom siv hluav taws xob tiv thaiv.
Qhov zoo
1, Vim hais tias ntawm cov txheej txheem tshwj xeeb ntawm peb roughening nto, nws tuaj yeem tiv thaiv hluav taws xob tawg.
2, Vim hais tias cov qauv nplej ntawm peb cov khoom yog equiaxed zoo siv lead ua kheej kheej, nws shortens lub sij hawm ntawm kab etching thiab txhim kho qhov teeb meem ntawm cov kab tsis sib luag sab etching.
