Kuchokera pazotsatira zoyeserera, zimapezeka kuti izi zimayesedwa kwambiri: M'mbuyomu, ndazindikira kuti EDD ingawononge zigawozo, koma sindimayembekezera kuti ndizilipira ndalama zokwanira.
ESD ndi zomwe timakonda kutcha electro-static. Kuchokera mu kudziwa zomwe mwaphunzira, zitha kudziwika kuti magetsi okhazikika ndi zinthu zachilengedwe, omwe nthawi zambiri amapangidwa kudzera mu ma volts ambiri komanso ma volts masauzande ambiri. Pazinthu zamagetsi, ngati kapangidwe ka ESD sikunapangidwe bwino, ntchito yamagetsi yamagetsi ndi yamagetsi nthawi zambiri imakhala yosakhazikika kapena yowonongeka.
Njira ziwiri nthawi zambiri zimagwiritsidwa ntchito mukamachita mayeso a ESD: Kulumikizana ndi Kulumikizana ndi Kutulutsa kwa mpweya.
Kutulutsa kulumikizana ndikutulutsa mwachindunji zida zoyesedwa; Kutulutsa kwa mpweya kumatchedwanso zotulutsa mosasintha, zomwe zimapangidwa ndi kuphatikiza kwa maginito olimba a magnetic to oyandikira. Magetsi oyeserera a mayeso awiriwa nthawi zambiri amakhala 2kv-8kv, ndipo zofuna zake ndizosiyana m'magawo osiyanasiyana. Chifukwa chake, musanapange, tiyenera kudziwa msika.
Zomwe zili pamwambazi ndi mayeso oyambira pazogulitsa zamagetsi zomwe sizingagwire ntchito chifukwa cha magetsi amagetsi kapena zifukwa zina pomwe thupi la munthu limalumikizana ndi zinthu zamagetsi. Chiwerengero chomwe chili pansipa chikuwonetsa zigawo za chinyezi cha zigawo zina m'miyezi yosiyanasiyana ya chaka. Itha kuwoneka kuchokera ku chithunzi chomwe a Lasvegas ali ndi chinyezi chochepa chaka chonse. Zogulitsa zamagetsi m'derali ziyenera kusamala kwambiri kuti atetezedwe.
Chinyezi chimakhala chosiyana m'malo osiyanasiyana padziko lapansi, koma nthawi yomweyo m'derali, ngati chinyezi cha mpweya sichilinso chimodzimodzi, magetsi okhazikika omwe amapangidwa nawonso amakhala osiyananso. Gome lotsatirali ndi data yomwe imasonkhanitsidwa, komwe imatha kuwoneka kuti magetsi okhazikika amawonjezeka ngati chinyezi cha mpweya chimachepa. Izi mosavuta zimafotokozanso chifukwa chomwe kupembedza kokhazikika komwe kumatulutsidwa pochotsa thukuta kumpoto kwa nyengo yachisanu ndi yayikulu kwambiri. "
Popeza magetsi owerengeka ndi owopsa, kodi tingachiteteze bwanji? Mukamapanga chitetezo chamagetsi, nthawi zambiri timachigawa m'magawo atatu: kupewa milandu yakunja kuti isayende bwino ndikuyambitsa; Pewani minda yamagetsi yakunja kuti muchepetse bolodi la madera; Pewani kuwonongeka kwa minda yamagetsi.
Mwa kapangidwe kadera, tidzagwiritsa ntchito njira zingapo zotsatirazi zachitetezo chamagetsi:
1
Zida za Avalalche za chitetezo chamagetsi
Iyi ndi njira yomwe nthawi zambiri imagwiritsidwa ntchito popanga. Njira yomwe ingalumikizane ndi kuphatikizira dedide mpaka pansi mofanana ndi mzere wa siginecha. Njirayi ndikugwiritsa ntchito dalade dade yoyankha mwachangu ndikukhazikitsa mphamvu yokhazikika, yomwe imatha kudya magetsi apamwamba munthawi yochepa kuti muteteze bolodi.
2
Gwiritsani ntchito ma caltur ogwiritsa ntchito magetsi otetezera
Mu njira iyi, a capocitor a ceramic omwe ali ndi voliyumu ya 1.5kv nthawi zambiri amaikidwa mu I / O Clactor kapena mawonekedwe a chizindikiro chachikulu, ndipo mzere wolumikizira ndi wocheperako kuti muchepetse chiwongola dzanja. Ngati cartacitor wokhala ndi magetsi ocheperako akagwiritsidwa ntchito, zimawononga pagalimotoyo ndikusiya kutetezedwa.
3
Gwiritsani ntchito mikanda ya Ferrite kuti chitetezo
Mikanda ya Ferring imatha kuzindikira za ESD yamakono, ndipo imathanso kusokoneza radiation. Tikakumana ndi mavuto awiri, a Ferngete ndi chisankho chabwino kwambiri.
4
Njira yopumira
Njirayi imawoneka mu chidutswa. Njira yodziwika bwino ndikugwiritsa ntchito mkuwa wa Triangelar ndi nsonga zogwirizana ndi wina ndi mnzake pamzere wa micystrip yopangidwa ndi mkuwa. Mapeto ake amkuwa atatumiri amalumikizidwa ndi chingwe chamanja, ndipo inayo ndi mkuwa wa Thunger. Kulumikizana pansi. Pakakhala magetsi okhazikika, imabweretsa zotupa kwambiri komanso mafuta amagetsi.
5
Gwiritsani ntchito njira ya LC kaseweredwe kuti muteteze magemu
Zosefera zopangidwa ndi LC zitha kuchepetsa magetsi okwanira pafupipafupi kuti asalowe mdera. Kuchita zinthu mosangalatsa kwa intuctor ndikwabwino polepheretsa nthawi zambiri za ESD kuti asalowe mderalo, pomwe wamkuluyo amaletsa mphamvu zambiri za ESD pansi. Nthawi yomweyo, zosefera zamtunduwu zimathanso kusalala m'mphepete mwa chizindikirocho ndikuchepetsa rf mphamvu, ndipo magwiridwewo akhala akuyenda bwino pankhani ya chizindikiro.
6
Bolodial Board for Force
Ndalama zikaloledwa, kusankha bolodi ya mitundu mitundu ndi njira yothandiza kupewa kupewa ESD. Mu bolodi yosanjikiza kwambiri, chifukwa pali ndege yathunthu yoyandikira, izi zitha kupangitsa kuti banja likhale lotsika mwachangu, kenako kuteteza udindo wa zizindikiro zazikulu.
7
Njira yosiyira gulu lotetezera pamatayala otetezera
Njirayi imakonda kujambula mayendedwe ozungulira oyendetsa madera osatentha. Makhalidwe akakhala chilolezo, kulumikiza mayendedwe a nyumba. Nthawi yomweyo, ziyenera kudziwika kuti kufufuza sikungapangitse chiuno chotsekeka, kuti chisapangire chotupa ndi kubweretsa zovuta zambiri.
8
Gwiritsani ntchito zida za CMOS kapena zida za TTL ndi ma domisoves owonera otetezedwa
Njirayi imagwiritsa ntchito mfundo yodzipatula kuti muteteze bolodi. Chifukwa zida izi zimatetezedwa ndi madoomi omata, zovuta zomwe mapangidwewo zimachepetsedwa mu kapangidwe kadera.
9
Gwiritsani ntchito ma carpouting
Makina owonda awa ayenera kukhala ndi malingaliro ochepera esl ndi ESR. Pafupifupi pafupipafupi esd, ma carpoctors okhazikika amachepetsa malowa. Chifukwa cha zotsatira za esl, ntchito ya electrolyte imafooka, yomwe imatha kusefa ndi mphamvu zapamwamba kwambiri. .
Mwachidule, ngakhale esd ndizowopsa ndipo zimatha kubweretsa zovuta zazikulu, koma pokhapokha poteteza mphamvu ndi zizindikiro paderali zitha kuteteza ESD masiku kuti isayende mu PCB. Mwa iwo, abwana anga ankakonda kunena kuti "kuyika bwino kwa bolodi ndiye mfumu". Ndikukhulupirira kuti chiganizo ichi chikhoza kukubweretsaninso zotsatira za kuthyoka thambo.
