Xaiv txoj cai electromagnetic shielding enclosure rau koj lub lab yog qhov kev txiav txim siab tseem ceeb uas sib npaug kev ua haujlwm, kev siv tau zoo, thiab kev siv nyiaj txiag. Kev ua yuam kev tuaj yeem ua rau muaj kev tiv thaiv tsis txaus, kev sim tsis raug cai, lossis tus nqi tsis tsim nyog. Ua raws li phau ntawv qhia no kom paub xaiv.
Kauj ruam 1: Precisely Definition koj Shielding Requirements
Koj daim ntawv thov tshwj xeeb dictates txhua yam. Qhov xav tau kev tiv thaiv kev ua tau zoo (SE)- ntsuas hauv decibels (dB) ntawm attenuation- sib txawv heev.

Yam yuav tsum tau muaj kev tiv thaiv zoo (SE) |
Cov Lus Qhia Tseem Ceeb & Cov Lus Cim |
|
General -Lub Hom Phiaj EMC/EMI Ua Ntej- Kev Ntsuas Ua Raws Cai |
60 - 100 dB |
Broadband, los ntawm ~ 30 MHz mus rau 18 GHz. Yuav tsum tau txwv ambient RF suab nrov kom raug emissions thiab kev tiv thaiv kab mob. |
|
MRI Suite lossis Sensitive Biomedical Instrumentation |
80 - 120 dB |
Tseem ceeb ntawm qhov tshwj xeeb RF zaus ntawm cov khoom siv los tiv thaiv cov duab distortion thiab ua kom muaj kev nyab xeeb. |
|
Kev Ruaj Ntseg Kev Sib Txuas Lus / TEMPEST / Kev Txawj Ntse |
100 dB + |
Attenuation siab heev nyob rau hauv ib tug dav spectrum los tiv thaiv kev cuam tshuam emanations thiab xyuas kom meej lub teeb liab cais. |
|
Kev Tshawb Fawb Microelectronics |
60 - 80 dB |
Tsom ntsoov rau kev tswj xyuas qis dua - zaus sib nqus teb thiab electrostatic tawm, ntxiv rau RF. |
Kev Ua: Tham txog cov qauv uas cuam tshuam rau koj txoj haujlwm (xws li IEEE Std 299, MIL-STD-188-125) thiab koj phau ntawv qhia khoom siv los txheeb xyuas koj lub hom phiaj SE thiab ntau zaus.
Kauj Ruam 2: Ntsuam xyuas cov ntaub thaiv npog & kev tsim kho
Nrog koj lub hom phiaj kev ua tau zoo, xav txog kev daws lub cev.
Modular Shielded Rooms: Tsim los ntawm interlocking shielding panels (feem ntau steel los yog tooj liab-clad). Lawv muab qhov yooj yim tshaj plaws rau qhov loj me, kev nthuav dav yav tom ntej, thiab kev ua haujlwm siab heev (100+ dB). Zoo tagnrho rau kev ruaj khov, siab -spec labs.
Ua ntej-fabricated Shielded Enclosures: Factory- ua cov txee lossis chav me me. Lawv muab kev ua tau zoo heev (80-120 dB) rau qhov ntau thiab tsawg thiab ua kom nrawm dua. Zoo meej rau vaj tse tshwj xeeb cov cuab yeej xws li network analyzers lossis raws li lub chaw kuaj kev nyab xeeb.
Flexible / Fabric Screened Rooms: Ua los ntawm cov ntaub siv hluav taws xob. Lawv muab qhov zoo attenuation (40-80 dB) rau qis dua- cov ntawv thov zaus los yog cov nqi tsim nyog, nqa tau yooj yim rau cov kev xav tau ib ntus.
Lub ntsiab feature tsom xam: Txawm li cas los xij, txheeb xyuas lub qhov rooj tiv thaiv (qhov loj tshaj plaws muaj peev xwm xau), hluav taws xob lim vaj huam sib luag rau cov kab hluav taws xob, waveguide air vents rau HVAC, thiab RF connector feedthroughs rau cov ntaub ntawv cables. Cov Cheebtsam no yuav tsum ua kom zoo sib xws ntawm lub kaw lus SE tag nrho.
Kauj Ruam 3: Xav txog kev sib koom ua ke ntawm Kev Ua Haujlwm Lab
Kev ua tau zoo yuav tsum ua raws li qhov tseeb. Nug:
Space & Access: Nws puas haum koj lub chaw kuaj hneev taw thiab qab nthab qhov siab? Koj puas tuaj yeem tau txais nws los ntawm lub qhov rooj thiab txoj hauv kev rau kev teeb tsa?
Ib puag ncig sab hauv: Koj puas xav tau teeb pom kev zoo, hluav taws xob hluav taws xob, kev tswj hwm huab cua, lossis hluav taws kub kub hauv? Cov no yuav tsum tau koom ua ke nrog EMC-cov khoom ua tau raws.
Yav tom ntej-Kev pov thawj: Puas yog koj qhov zaus lossis SE xav tau hloov pauv? Modular chav muab kev hloov kho kom yooj yim dua.
Certification & Testing: Xav tau ib daim ntawv tshaj tawm - kev teeb tsa kev ntsuas qhov ntsuas qhov ntsuas (raws li tus qauv lees paub zoo li IEEE 299) los ntawm tus neeg muag khoom los txheeb xyuas qhov kev thov ua haujlwm.
Kauj Ruam 4: Xaiv Tus Neeg Ua Haujlwm Tsim Nyog
Qhov no tsis yog kev yuav khoom. Xaiv ib lub chaw tsim khoom nrog:
Cov kws tshaj lij pov thawj hauv koj daim ntawv thov daim ntawv thov (kev kho mob, tub rog, R & D).
Cov ntaub ntawv pov thawj thiab cov qauv -cov ntaub ntawv xeem ua raws.
Tag nrho - cov kev pabcuam uas suav nrog kev tsim, kev teeb tsa, thiab tom qab- kuaj kev teeb tsa.
Los ntawm kev ua haujlwm raws li cov kauj ruam no -los ntawm kev txhais cov kev xav tau rau kev soj ntsuam cov neeg muag khoom- koj yuav muaj kev ruaj ntseg ib puag ncig uas tiv thaiv kev ncaj ncees ntawm koj lub chaw kuaj xyuas kev ua haujlwm siab tshaj plaws.
Rau kev ntsuam xyuas kev tshaj lij thiab cov kev daws teeb meem uas ua tau raws li cov qauv kev tiv thaiv meej uas koj lub chaw kuaj mob xav tau, thov hu rau peb: Wuxi Anxin Shielding Equipment Co., Ltd. Peb tshwj xeeb hauv kev tsim, tsim, thiab ntawv pov thawj ntawm siab -kev ua haujlwm tiv thaiv ib puag ncig.
