r tus nqi / n tus nqi iso 10113 r ntau dua lossis sib npaug nrog 1.6, n ntau dua lossis sib npaug rau 0.20 (txhua pob)
Nto zoo en 10130 tsis muaj khawb los yog cov menyuam cov cim . 100}% pom kev kuaj xyuas
4. Cov kev tswj hwm zoo
Saib Xyuas Xyuas:
Tsis tsim nyog tsis txaus ntseeg: qhov, nti, oxide nplai
Cov ntawv tso cai me me: cov menyuam yaus cov cim (tsawg dua los yog sib npaug rau 3 / yob, tsawg dua los yog sib npaug rau 20mm nyob rau hauv ntev)
Kev nyiam huv yuav tsum muaj:
Residual roj tsawg dua los yog sib npaug nrog 50mg / m² (electroplating qib yuav tsum muaj tsawg dua los yog sib luag rau 20mg / m²)
Tshauv cov ntsiab lus ntsuas (tsawg dua lossis sib npaug rau 10mg / m²)
5. Kev tswj hwm qhov chaw raug
Thickness kam rau:
Cov qeb: ± 0.05 hli
Precision Qeb: ±03mm (xav tau rau cov vaj tse sab nrauv sab nrauv)
Qauv Qauv Kho:
Ncaj tsawg dua los yog sib npaug rau 3 hli units (tsawg dua los yog sib npaug rau 1.5i rau cov ntawv thov high-end-ills)
Ntug thinning tsawg dua los yog sib npaug rau 5% ntawm nominal tuab
6. Ntim, cia, thiab tsheb thauj khoom tshwj xeeb
Rust-pov thawj ntim:
VCI anti-xeb daim ntawv + PE zaj duab xis (lub sijhawm ntim tsawg dua lossis sib npaug li 6 lub hlis)
Desiccant yuav tsum rau dej hiav txwv (av noo tsawg dua los yog sib npaug 40% rh)
Stacking yuav tsum:
Cov tshooj siab tshaj plaws tshooj qis dua lossis sib npaug ntawm 3 meters (kom tsis txhob deformation)
Qhov chaw cia kub 10-40 degree, txheeb ze cov av noo tsawg dua los yog sib npaug rau 60%
7. Daim ntawv thov-sab zoo tswj
Cov ntawv pov thawj stamping:
Mesh kev tsom xam ntawm thawj ntu (lim cov kev kos duab sib piv ntau dua lossis sib npaug rau 2.0)
Saib xyuas kom tawg thiab wrinkling qhov tsis xws luag (tuag sib hloov kho)
Vuam Kev Ntsuam Xyuas:
Chaw pov thawj parameter pov thawj (electrode siab 2-4 kn, tam sim no 8-10 yim)
