Anti-omwe amalowererapo ndi ulalo wofunikira kwambiri mu kapangidwe ka dera ka dera ka madera, zomwe zimawonetsera machitidwe ndi kudalirika kwa dongosolo lonse. Kwa ma pcb akatswiri, kapangidwe ka anti-omwe amasokonezedwa ndi mfundo yofunika kwambiri kuti aliyense ayenera maluso.

Kukhalapo kwa kusokonezedwa mu kabati ya PCB
Mwa kafukufuku weniweni, zimapezeka kuti pali zosokoneza zazikulu zinayi mwa kapangidwe ka PCB: Nyuzipepala yamphamvu, kulumikizana kwa mzere wophatikizika, kuphatikiza ndi electromaagnetic (EMI).

1. Phokoso lamphamvu
M'chigawo chokwanira kwambiri, phokoso la magetsi lili ndi chiwonetsero chodziwikiratu pa signal. Chifukwa chake, chofunikira choyamba pakupanga magetsi kuli phokoso lochepa. Apa, malo oyera ndi ofunikira monga gwero loyera.

2. Mzere wofalitsa
Pali mitundu iwiri yokha ya mizere yotumiza mu PCB: Mzere wa Strip ndi Microwave. Vuto lalikulu kwambiri ndi mizere yofanapo ikuwonetsa. Kuganizira kumabweretsa mavuto ambiri. Mwachitsanzo, siginecha ya katunduyo idzakhala yopambana ya chizindikiro choyambirira komanso chizindikiro cha Echo, chomwe chingakulitse vuto lalikulu; Kulingalira kudzayambitsa kutaya kobwerera (kubweza), komwe kumakhudza chizindikirocho. Zotsatira zake ndizofunika kwambiri chifukwa cha zomwe zimachitika chifukwa chowonjezera phokoso.

3. Kulumikizana
Chizindikiro cholowererapo chomwe chimayambitsa matenda chimayambitsa kusokonezedwa ndi ma electromaagnetic kupita ku njira yamagetsi kudzera mu njira ina yolumikizirana. Njira yolumikizirana yosavuta siyingakhale yothandizapo pakompyuta yamagetsi kudzera mu mawaya, malo, mizere yofala, yofananira, kulumikizana, ma radiation, ma radiation, ma radiation, ma radiation, radiation.

4.
Zosokoneza electromagnetic EMI ili ndi mitundu iwiri: kugwirizanitsidwa ndi kusokonezedwa. Kuphatikizika komwe kumachitika kumatanthauza kulumikizana (kulowerera) kwa zizindikiro pa intaneti imodzi yamagetsi kupita ku netiweki ina yamagetsi kudzera pa intaneti. Kuphatikizika kwa radied kumatanthauza gwero logawika (kulowererapo) chizindikiro chake ku intaneti ina yamagetsi kudutsa malo. Mu wothamanga kwambiri PCB ndi dongosolo la makina othamanga, zikhomo zophatikizana ndi madera, zolumikizira zosiyanasiyana, zomwe zimapangitsa kuti ma radiation ekrectromaagnetro. ntchito yabwinobwino.

PCB ndi Curcuit Anti-inniction
Kapangidwe kamina yotsutsa mabwalo osindikizidwa kumagwirizana kwambiri ndi dera linalo. Kenako, tingofotokoza zina zofotokoza zina pamapangidwe angapo a PCB antimits.

1.
Malinga ndi kukula kwa madera osindikizidwa pano, yesani kuwonjezera m'lifupi mwa mzere wamagetsi kuti muchepetse kulanda kwakhungu. Nthawi yomweyo, pangani malangizo a mzere wamagetsi ndi mzere wa nthaka mogwirizana ndi kuwongolera kufala kwa deta, komwe kumathandizira kukulitsa luso la anti-rise.

2. Kapangidwe kaya
Kulekanitsa digito pansi kuchokera ku analog. Ngati pali zigawo zonse zomangira ndi mabwalo a mzere pa bolodi la madera, ayenera kulekanitsidwa momwe angathere. Nthaka ya madera otsika-mofatsa iyenera kukhala yofanana mofananamo limodzi momwe mungathere. Pamene lumo lenileni limakhala lovuta, limatha kulumikizidwa pang'ono mogwirizana kenako ndikukhazikika. Madera oyendetsa bwino akonzekeseke azikhala ndi magawo angapo mu mndandanda, waya wapansi ayenera kukhala wamfupi komanso wandiweyani, ndipo zojambulazo zapamwamba za malo ziyenera kugwiritsidwa ntchito mozungulira gawo lazikulu.

Waya wapansi uyenera kukhala wonenepa momwe angathere. Ngati mzere wowonda kwambiri umagwiritsidwa ntchito ngati waya wapansi, ndikuyika zomwe zingachitike ndi zomwe zilipo, zomwe zimachepetsa phokoso. Chifukwa chake, waya wapansi uyenera kunenedwa kuti utha kupitirira katatu kovomerezeka pa bolodi. Ngati ndi kotheka, waya wapansi uyenera kukhala pamwamba pa 2 ~ 3mm.

Waya wapansi amapanga chiuno chotsekedwa. Kwa mabodi osindikizidwa omwe adapangidwa mabwalo a digito, ambiri mwa mabwalo awo ambiri amakonzedwa mu malupu kuti asinthe phokoso.

3. Kusintha kwa mphamvu
Chimodzi mwazinthu wamba za kapangidwe ka PCB ndikukhazikitsa ma carecactors oyenera pamtundu uliwonse wa gulu losindikizidwa.

Mfundo zonse zosinthika za ma cacluting

① Lumikizani 10 ~ 100FIF entrolyly cakulurtotor Gaucator kudutsa mphamvu. Ngati ndi kotheka, ndibwino kulumikizana ndi 100Uf kapena kupitirira.

Zitsamba zilizonse, chip chilichonse cholumikizidwa chikho chizikhala ndi Cakocitor 0,01pf. Ngati kusiyana kwa bolodi sikokwanira, capakor ya 1-10pf ikhoza kukonzedwa pa tchipisi 4 ~ 8.

Zida za ③ror wokhala ndi luso lofooka komanso mphamvu yayikulu imasinthira, monga zida zosungirako za Ram ndi Rom.

④Agangano kutsogolera sikuyenera kukhala motalika kwambiri, makamaka paulendo wapafupipafupi suyenera kutsogolera.

4. Njira zothetsera zosokoneza electromagnetic mu kapangidwe ka PCB

Kulaula ①dude: Chiuno chilichonse chimakhala chofanana ndi antenna, motero tiyenera kuchepetsa kuchuluka kwa malupu, malo a chiuno ndi nyerere ndi nyerere. Onetsetsani kuti chizindikirocho chimangokhala ndi njira imodzi yokhayo iliyonse, pewani malupu ojambula, ndikuyesera kugwiritsa ntchito mphamvu.

Kutulutsa: kusefedwa kumatha kugwiritsidwa ntchito kuchepetsa Eni onse pa mzere wamagetsi komanso pamzere wazizindikiro. Pali njira zitatu: ma carports ojambula, osefera em, ndi zigawo za maginito.

③Shield.

④ Yesani kuchepetsa kuthamanga kwa zida zapamwamba.

Kuchulukitsa dielect pafupipafupi kwa bolodi ya PCB kungalepheretse magawo apamwamba monga gawo laumunda pafupi ndi bolodi ku Walding kupita kunja; Kuchulukitsa makulidwe a PCB ndikuchepetsa makulidwe a micrestrip kungalepheretse waya wamagetsi kuti usagwedezedwe komanso kupewa radiation.
