Kuv tseem nco txog ib txoj hauj lwm uas peb tau ua ob peb xyoos dhau los rau lub chaw kuaj semiconductor. Lawv muaj ntau- lab-duas tshuaj xyuas rigs uas khaws pov tseg random, untraceable yuam kev. Cov sensors yog brand tshiab, lub software yog flawless, tab sis cov ntaub ntawv xeem cia drifting. Lawv tau npaj mus khawb cov khoom siv.
Thaum kuv coj kuv pab neeg nrog lub spectrum analyzer, peb pom tus neeg ua txhaum nyob rau hauv li nees nkaum feeb: ib tug tshiab coj mus muag xov tooj cua transmitter tau nce mus txog ib mais deb, thiab nws lub zog RF tau dej nyab lub lab. Tus neeg siv khoom tau tsim "chav thaiv" lawv tus kheej siv cov hlau tuab, tab sis nws tau xau zoo li lub sieve.
Kuv tau ua engineering RF shielding cov kev daws teeb meem nrog Wuxi Anxin Shielding Equipment Co., Ltd. rau ntau tshaj 15 xyoo, thiab kuv tuaj yeem qhia rau koj txog qhov no: kev tsim lub tshuab hluav taws xob tiv thaiv hluav taws xob tsis yog hais txog vuam tuab hlau ua ke. Yog tias koj kho nws zoo li lub thawv hlau tsis tu ncua, koj cov khoom siv hluav taws xob tsis zoo yuav tseem ua tsis tiav.
Nov yog qhov tshwm sim tiag tiag hauv thaj teb, thiab yuav ua li cas lub chaw tsim khoom RF thaiv kev tiv thaiv kom tsis txhob muaj kev ntxhov siab tsis pom.
Cov lus dab neeg "Thick Steel": Vim li cas Qhov Rooj thiab Seams tseem ceeb tshaj
Qhov yuam kev loj tshaj plaws uas kuv pom ntawm - qhov chaw yog cov neeg siv khoom xav txog lub vaj huam sib luag thickness thaum tsis quav ntsej cov seams. Lub 3 hli steel phab ntsa tsis muaj txiaj ntsig yog tias lub qhov rooj sib txawv ua zoo li lub kav hlau txais xov loj.
Nyob rau hauv lub semiconductor lab kuv tau hais, cov hlau yog tuab, tab sis lub qhov rooj tsuas yog hinged nrog cov qauv roj hmab weatherstripping. Roj hmab tsis muaj dab tsi tiv thaiv siab - zaus RF. Thaum peb rov tsim lawv lub tawb, peb tsis yog hloov cov hlau xwb; peb tag nrho re-engineered lub perimeter. Peb tau nruab nruam beryllium tooj liab ntiv tes nyob ib ncig ntawm lub qhov rooj ncej. Thaum lub qhov rooj kaw, cov ntiv tes compressed thiab tsim ib qho khoom siv hluav taws xob txuas ntxiv. Peb kuj yuav tsum tau khi cov hinges kom zoo kom lub qhov rooj nws tus kheej los ua ib feem ntawm daim ntaub thaiv. Thaum peb kaw cov qhov khoob no, lub suab nrov hauv pem teb poob los ntawm 80dB, thiab cov khoom siv kuaj ua haujlwm zoo kawg nkaus.
Qhov cua ntxiab: Cia cua hauv, Khaws RF tawm
Ntawm no yog qhov kev npau suav phem hauv classic: koj kaw lub tawb kom zoo, tab sis cov khoom siv rhiab hauv tsim ua kom muaj cua sov. Txhawm rau kom nws txias, tus txij nkawm tau txiav ib lub qhov thiab muab tso rau hauv ib lub kiv cua txheem nrog lub xaim mesh. Mam li nco dheev, lub shielding yog puas. Cov hlau mesh ntawd yog qhov loj npaum li cas los ua tus kav hlau txais xov muaj txiaj ntsig zoo rau microwave frequencies.
Koj tsis tuaj yeem thaiv huab cua xwb; koj yuav tsum dag RF. Ntawm Wuxi Anxin, peb daws qhov no los ntawm kev txhim kho honeycomb waveguide vent panels. Cov no zoo li ib pawg me me ntawm txhuas hexagonal raj. Qhov tob thiab txoj kab uas hla ntawm cov hlab no yog lej suav kom cia cov huab cua ntws los ntawm kev ywj pheej, tab sis lawv lub cev choke thiab thaiv electromagnetic nthwv dej saum toj ntawm qee zaus. Nws yog ib qho ntawm cov txuj ci zoo nkauj engineering uas nyuam qhuav ua haujlwm.
"Trojan Nees": Lub Hwj Chim thiab Teeb Nres Cables
Koj tuaj yeem tsim lub thawv hlau zoo tshaj plaws nyob hauv lub ntiaj teb, tab sis yog tias koj khiav lub zog hluav taws xob tsis muaj hluav taws xob ncaj qha los ntawm phab ntsa, koj tsuas yog muab EMI daim VIP hla mus rau hauv koj lub tawb. Lub cable ua raws li cov kav dej, nqa lub suab nrov sab nraud rau koj cov khoom siv hluav taws xob.
Txhua qhov kev nkag mus yuav tsum tau kho raws li qhov tsis muaj zog. Rau cov kab hluav taws xob, peb koom ua ke hnyav - lub luag haujlwm EMI fais fab kab lim ncaj qha rau hauv cov phab ntsa thaiv, kom ntseeg tau tias txoj hauv av tsis tu ncua. Rau siab - cov ntaub ntawv ceev ceev, cov kab tooj liab yuav ib txwm xau. Peb mus- mus rau qhov kev daws teeb meem? Hloov cov teeb liab mus rau fiber ntau optics ua ntej nws nkag mus rau hauv lub tawb. iav tsis ua hluav taws xob, txhais tau tias xoom RF to. Yog tias nws yuav tsum yog tooj liab, peb siv tshwj xeeb RF waveguide raj rau kev nkag mus.
Tsis txhob kwv yees, Pib Engineering
Tiv thaiv cov khoom siv hluav taws xob rhiab tsis yog hais txog kev yuav cov hlau hnyav tshaj plaws; nws yog hais txog kev nkag siab txog koj ib puag ncig kev hem thawj tshwj xeeb. Yog tias koj xav tau thaiv lub teeb liab 1 GHz, lub tawb tsim rau 10 MHz yuav tsis pab koj.
Yog tias koj cov cuab yeej raug kev txom nyem los ntawm cov ntaub ntawv drift, tsis muaj tseeb, lossis teeb liab kev noj nyiaj txiag, tsis txhob liam rau cov khoom siv xwb. Kho ib puag ncig.
Ntawm Wuxi Anxin Shielding Equipment Co., Ltd., peb tsis yog xa koj cov vaj huam sib luag. Peb ua raws li koj cov kev koom tes. Xa peb koj cov khoom siv specs, qhov cuam tshuam ntau zaus koj sib ntaus sib tua, thiab koj qhov chaw teeb tsa. Kuv pab neeg ua haujlwm engineering yuav suav qhov kev tiv thaiv kev ua tau zoo uas koj xav tau thiab tsim ib qho kev cai RF enclosure uas ua haujlwm hauv lub ntiaj teb tiag.
Hu rau Wuxi Anxin hnub no, thiab cia peb nyob ntsiag to uas cuam tshuam rau qhov zoo.
FAQ
Q: Cov txheej txheem steel puas tuaj yeem tiv thaiv cov khoom siv hluav taws xob los ntawm EMI?
A: Tsis yog. Thaum cov hlau thaiv qee qhov qis- zaus sib nqus teb, cov thawv txheem steel nrog cov roj hmab qhov rooj ntsaws ruaj ruaj lossis cov khoom siv tsis muaj cov kab hluav taws xob ua haujlwm zoo li cov kav hlau txais xov rau siab - zaus RF. Kev tiv thaiv tiag tiag yuav tsum tau txuas hluav taws xob txuas ntxiv, xws li beryllium tooj liab ntiv tes gaskets thiab EMI lim.
Q: Koj ua li cas cov cuab yeej txias hauv RF shielding tawb yam tsis muaj kev cuam tshuam?
A: Peb siv honeycomb waveguide vent panels. Qhov sib sib zog nqus, nqaim txhuas lub hlwb tso cai rau siab - ntim airflow kom txias tab sis lub cev thaiv cov electromagnetic nthwv dej los ntawm kev hla, tswj lub tawb tiv thaiv kev ua tau zoo.
Q: Dab tsi yog qhov ua yuam kev loj tshaj plaws ua thaum txhim kho cov hlua khi?
A: Tsis quav ntsej txog kev nkag mus rau cable. Kev khiav tsis muaj zog lossis tooj liab cov ntaub ntawv cables ncaj qha los ntawm cov phab ntsa tiv thaiv hla dhau lub qhov rooj tag nrho, ua tus "Trojan nees" uas coj EMI ncaj qha mus rau cov khoom siv rhiab heev.
