3. Lub luag haujlwm ntawm lub vev xaib
Uniwell yog ib tug thawj coj hauv Printed Circuit Board cov tswv yim thiab cog lus los koom tes nrog kev ua haujlwm nrog peb cov neeg muas zaub thiab lwm tus neeg los txheeb xyuas thiab tshem tawm cov khoom phom sij ntawm lawv cov khoom. Raws li ib tug ISO 9001 sau npe tuam txhab, Uniwell yog kev txhawb nqa kev lag luam hauv tuam txhab hauv thoob ntiaj teb kom siv cov hmoov lead thiab lwm yam khoom uas tsis zoo.
4.Luag kev paub txog Rohs
1) RoHS Cov Khoom Qhia thiab Cov Khoom Ntaw
Epec muab RoHS Daim Ntawv Tso Cai Ua Haujlwm (C ntawm C) nrog rau tag nrho cov khoom xa tuaj. Kev tso cai yooj yim rau txhua tus RoHS cov khoom thiab cov ntaub ntawv, tag nrho peb cov ntim muaj ib daim RoHS / Pb-dawb ntawv.
2) IPC-1752 RoHS Cov Ntawv Cag Lus Txuj Ci
Kev ua raws cai yuav tsum tau hais tias Epec thiab peb cov neeg muag khoom nkag siab txog cov khoom siv ntawm peb cov khoom-ntawm FR4 laminate, solder mask, silkscreen, thiab plating, mus rau qhov chaw tiav thiab cov laug cam. Peb yuav muab cov ntaub ntawv thiab daim ntawv tshaj tawm cov ntaub ntawv coj los pab txhawb koj cov "kev mob siab rau." Koj yuav tsum tau muab cov ntaub ntawv no thaum thov txog EU regulators.
3) RoHS Cov Kev Xeem Tshaj Tawm Tsawg
Epec tau txais ntau yam ntawm RoHS raws qhov ua tiav qhov kev npaj tiav.
Cov kev xeem tiav no muaj xws li:
Xaus Ntoo | Txee Lub neej | Coplanarity | Ntau Cov Haujlwm Ua Haujlwm |
ENIG | Kaum Ob Hlis | Muaj | Muaj |
Immersion Silver | * 6-9 Lub Hlis | Muaj | Txwv |
Lead dawb HASL | 12 Lub Hlis | Ntsig | Muaj |
OSP | 6-12 Lub Hlis | Muaj | Tsis yog |
Immersion Tin | 3 Lub Hlis | Muaj | Txwv |
* Nrog ntim thiab ntim cia kom zoo
Cim npe nrov: RoHS ua raws cai luam tawm Circuit Board, China, suppliers, manufacturers, khw, pheej yig, customized, luv nqi, siab zoo, quotation
