Nws ingeniously muab tshuab tooj liab zoo nkauj nrog kev tshem tawm cov teeb meem zoo li cov teeb meem tseem ceeb thiab cov kev cuam tshuam hluav taws xob kom haum (ESD), kev sib txuas lus hluav taws xob, thiab kev sib txuas.
Lub tooj liab ntawv ci nrog cov kev coj ua lossis tsis - Cov nplaum acrylic ua rau nce cov kab xev. Rau ntau cov ntawv thov, nws ua rau pom kev ua haujlwm zoo tshaj plaws thiab EMI cov nqi thaiv cov yam ntxwv.
Qaum Nta Ntawm Tooj Ntawv Ntawv Nyiaj
Kev ua haujlwm siab: tus tooj ntawv ntawv ci ntawv tau kub hluav taws xob tsis kam, thaum cov txheej txheem nplaum nplaum kom ntseeg tau tag nrho kev ua haujlwm.
Zoo heev EMI Shielding effidentess: tooj liab yog tus neeg xyuas coj zoo, ua tau zoo xav thiab nqus hluav taws xob hluav taws xob tsis siv hluav taws xob. Kev tiv thaiv cov txiaj ntsig zoo (SE) feem ntau yog tshaj 30 db, nrog high- kev ua tau cov khoom ncav cuag 70 db lossis ntau dua.
Cov thermal zoo heev: pab hauv tshav kub dissipation.
Yooj yooj yim & cov txheej txheem: yooj yim txiav, khoov, thiab ua raws li cov chaw sib xyaw.
Yooj yim adhesion: tev thiab lo rau kev ua haujlwm yooj yim.
Cov ntawv thov tseem ceeb ntawm tooj liab ntawv ci
Tooj Liab Ntawv Nyiaj Xev muaj ntau cov kev siv, feem ntau tsom rau nws cov kev coj ua, kev tiv thaiv, thiab tsev ntaub thaiv cov khoom:
Electromagnetic Shielding (EMI Tiv Thaiv):
Kev thaiv cov nqaws thiab cov khoob hauv cov tsev ntawm cov khoom siv hluav taws xob xws li cov xov tooj txawb, khoos phis tawj, khoos phis tawj; Cable Shielding (qhwv - nyob ib ncig ntawm lossis thawv thaiv tes zoo -} raws); zos tiv thaiv cov hluav taws xob sib xyaw (xws li hloov pauv thiab inductors); Seem Seem hauv Chav Tiv Thaiv; thiab kev txhawb nqa los yog them ib ntus tiv thaiv daim npog ntawm PCBs.
ESD Kev Tiv Thaiv:
Cov chaw ua haujlwm ua haujlwm, anti {- cov thawv zoo nkauj / tsheb thauj khoom hauv cov khoom siv hluav taws xob; Sealing ntim rau cov hluav taws xob sib xyaw; thiab dissipating cov nqi zoo li qub.
Hluav Taws Xob Kev & Hauv Pem Teb:
Jumper sib txuas thiab xoom {- Cov peev txheej sib txuas ntawm Circuit Court Cam; hluav taws xob sib lwv ntawm cov hlau tsis sib xws; muab txoj hauv kev hauv av rau cov khoom siv uas tsis tuaj yeem siv ncaj qha (xws li pom cov bezels thiab roj teeb); Thiab auxiliary tab sib txuas los yog ntsuas cov ntsiab lus sib txuas hauv cov roj teeb hluav taws xob tshiab hloov tshiab.
Cov Kab Phiaj Los Nqis Shielding:
Kho kho kom haum coaxial cables; Yooj yim tiv thaiv cov cleshielded (xws li USB cable thiab network cable) (qhwv tooj liab ntawv thiab av).
Lwm Yam Kev Siv:
Thaum tshav kub dissipation: hloov chaw kub los ntawm cov cua sov los ntawm cov khoom siv cua sov rau cov vaj tse lossis lub dab dej sov (yuav tsum tau cov khoom siv thermal interface).
Kev kho: kho cov kab xev circuitated (PCB) cov kab (ib qho kev ua haujlwm tsis muaj kev txawj ntse thiab tsim nyog daim kab xev).
Tuag - tej txiav: siv raws li cov khoom siv hauv paus, nws tau txiav rau hauv ntau cov duab rau cov khoom ua npuas dej, hauv av los ntawm daim ntaub thaiv npog cov ris tsho.
Yuav ua li cas xaiv High -} Zoo tooj liab ntawv ci?
Thaum xaiv tooj liab ntawv daim kab xev
Tooj liab ntawv ci yam thiab thickness:
Electrolytic tooj liab ntawv ci: tus nqi tsawg, txuas ntxiv ntawm sab nraud (matte), thiab kev hloov pauv tau zoo, ua rau nws tsim nyog rau kev tiv thaiv dav dav thiab grounding.
Rolled Tooj Liab Ntawv Nyiaj: du nto (glossy), nrog kev du me me, yoog tau, thiab flex nkees ua kom tsis kam. Nws yog qhov tsim nyog rau cov ntawv thov uas yuav tsum tau ua dua dabtsi yog khoov lossis ua kom sib dhos muag (xws li FPC
Thickness: For applications requiring high shielding and conductivity and requiring mechanical strength, choose thicker foil (eg, 70 μm); Rau cov ntawv thov yuav tsum muaj cov kev siv siab thiab ua kom haum rau cov chaw caws pliav, xaiv cov ntawv ci (piv txwv li, 18 μm).
Adhesive Hom: Qhov no yog qhov sib txawv!
Kev ua yeeb yam nplaum: Yuav tsum siv rau hauv cov ntawv thov uas yuav tsum muaj hluav taws xob txuas ntxiv (GROUNDING, kev sib txuas, txhua - ib ncig ntawm kev thaiv khaub ncaws). Them sai sai rau nws cov khoom tiv thaiv (feem ntau yuav tsum muaj<0.01 Ω·cm).
Tsis - Conductive Adhesive: Tsuas yog siv rau kev thaiv lossis npog cov ntawv thov uas tsis xav tau (piv txwv li, npog cov ntawv luam puas tooj). Tus nqi feem ntau qis dua li vuam.
Nto Kho:
Bare tooj liab: Muaj qhov kev coj zoo tshaj plaws tab sis yog nquag mus rau oxidation thiab blackening, muaj feem txo ntev {}} sij hawm kev ntseeg tau. Nws tseem muaj cov khoom lag luam zoo.
Tin plating: Muaj cov oxidation zoo tiv taus, solderability, thiab ci ci. Nws yog ib feem siv siv.
Nickel plating: Muaj cov oxidation zoo ua tsis kam, corrosion tsis kam, thiab hnav tsis kam. Nws silvery - ntsej muag dawb muaj cov tsis zoo sib xyaw ( Nws feem ntau siv nyob rau hauv high - kev ntseeg tau los yog cov chaw hnyav.
Cov xim pleev xim: Muaj tus nqi tsawg, muab qee qhov oxidation tiv taus, thiab los ntawm ntau cov xim (xim dub, grey, thiab lwm yam). Txawm li cas los xij, nws muaj tsis zoo jonuthability.
Cov khoom nplaum:
Adhesion: kom ntseeg tau cov nplaum kom ruaj ntseg rau ntau yam substrates (hlau, yas, iav, pcb, thiab lwm yam). Muaj nyob rau theem sib txawv.
Qhov kub kub kuj: Xaiv raws li cov neeg ua haujlwm kub (piv txwv li, siab} {{{{{4 {}} free soldering).
Cov kuab tshuaj / Tshuaj Kuj: Xav txog lub xub ntiag ntawm cov neeg sawv cev huv, flux, thiab lwm yam hauv daim ntawv thov ib puag ncig.
Tsawg VOC / Halogen - ywj pheej: ua raws li ib puag ncig cov cai (piv txwv li, rohs, ncav cuag).
Lub cev lub cev:
Tensile lub zog & elongation: cuam tshuam rau cov kua muag thiab ncab tiv taus thaum ua thiab siv.
Kev tiv thaiv cov txiaj ntsig zoo (SE): Tus nqi ua kom muaj nuj nqis rau qee qhov ntau zaus (piv txwv li 30 MHz-1 GHz), muaj txiaj ntsig zoo dua.
Tooj liab ntawv nyiajMuaj qhov chaw tshwj xeeb hauv cov khoom siv hluav taws xob niaj hnub thiab kev lag luam ua cov ntaub ntawv tiv thaiv kev tiv thaiv. Kev cuam tshuam kom zoo thiab siv ntawm tooj liab ntawv ntim cov kab xev, EMULATIONS FORRY POB TAWM, thiab kev tswj hwm kev daws teeb meem hluav taws xob, lossis muab cov kev daws teeb meem yooj yim. Yuav kom xaiv cov tooj liab zoo tshaj plaws
