ESD tsis yog ib qho txaus ntshai acronym. Nws yog qhov sawv ntawm koj lub microchips thiab kev puas tsuaj.
Hauv kev tsim khoom siv hluav taws xob thiab kev faib khoom, qhov kev hem thawj txaus ntshai tshaj plaws feem ntau pom tsis pom. Lub teeb me me uas koj tsis tuaj yeem pom lossis hnov - tsawg li 100 volts - tuaj yeem rhuav tshem lub microchip tam sim ntawd muaj nqis ntau txhiab daus las. Los yog phem dua, nws tuaj yeem tsim kev puas tsuaj uas ua rau tsis ua haujlwm ntau lub lis piam lossis ntau lub hlis tom qab, ua rau muaj kev lav phib xaub, kev puas tsuaj rau lub npe, thiab kev puas tsuaj loj.
NtawmYingFei Pob, peb tsis yog tsuas yog ua lub hnab rau electronics. Peb engineers electrostatic tiv thaiv tshuab uas tiv thaiv koj cov khoom rhiab ntawm lub Hoobkas hauv pem teb mus rau cov neeg siv kawg.
ESD yog dab tsi thiab Vim Li Cas Nws Tseem Ceeb?
Electrostatic Discharge tshwm sim thaum ob yam khoom uas muaj hluav taws xob sib txawv tuaj ze txaus rau lub txim dhia ntawm lawv. Hauv electronics:
Tib Neeg Lub Cev Qauv (HBM): Ib tus neeg taug kev ntawm cov ntaub pua plag tuaj yeem tsim 1,500-35,000 volts
Charged Device Model (CDM): Ib qho khoom siv nws tus kheej tuaj yeem raug them thiab tso tawm
Field-Induced Discharge: Muaj zog electrostatic teb tuaj yeem ua rau paug tawm los ntawm kev ntim khoom
Kev puas tsuaj ESD tsis yog ib txwm tam sim lossis pom tseeb:
Kev puas tsuaj loj: Tam sim ntawd, ua tiav cov khoom ua tsis tiav (5-10% ntawm cov neeg mob)
Kev puas tsuaj latent: Cov khoom tsis muaj zog uas ua tsis tiav ntxov (90-95% ntawm cov neeg mob)
Kev ntxhov siab tsis ua haujlwm: Ib ntus malfunction yam tsis muaj kev puas tsuaj mus tas li
Kev kwv yees kev lag luam qhia tias:
ESD ua rau $ 5 nphom hauv kev poob txhua xyoo rau kev lag luam hluav taws xob
Lub tuam txhab hluav taws xob nruab nrab poob 8-33% ntawm cov khoom rau ESD
Cov nqi zais: Warranty claims, field failures, brandnames puas
Peb Multi-Txheej ESD Kev Tiv Thaiv Tswv Yim:
Paj yeeb Poly
Surface resistivity: 10^9 - 10^12 ohms/sq
Tiv thaiv kom tsis muaj nqi
Zoo tagnrho rau: PCBA, connectors, feem ntau Cheebtsam
Kev Tiv Thaiv Dub
Surface resistivity: 10^3 - 10^6 ohms/sq
Tsim cov nyhuv Faraday tawb
Shields tiv thaiv sab nraud static teb
Zoo tagnrho rau: Sensitive ICs, tub rog / aerospace Cheebtsam
Metallized shielding
Surface resistance: <10^3 ohms/sq
Superior noo noo barrier zog
Lub teeb thaiv zoo heev
Zoo tagnrho rau: Moisture-sensitive devices, optoelectronics
Peb tau hnov txhua yam ntawm cov dab neeg - sensors tawg vim tsis muaj laj thawj thaum lub sij hawm thauj mus los, Circuit Court boards uas ua hauj lwm zoo nyob rau hauv lub laboratory malfunctioning thaum lub sij hawm siv tiag tiag, thiab cov khoom kim heev uas zoo li puas thaum lub sij hawm ua hauj lwm.
