Mapangidwe osinthika amatsatira kwambiri malamulo awiri:
1. Wosanjikiza aliyense wowoneka bwino ayenera kukhala ndi wosanjikiza (mphamvu kapena malo osanjikiza);
2.

Nkhani zotsatirazi zimachokera ku bolodi yochokera ku bolodi awiri kupita ku bolodi isanu ndi itatu kuti lifotokoze chitsanzo:
1.
Ma taxi awiri-osanjikiza awiri, chifukwa cha zigawo zochepa, palibenso vuto lodziwika bwino. Kuwongolera kwa radiation ya EMI kumaganiziridwa makamaka kuchokera kuzolowera ndi mawonekedwe;

Kugwirizana kwa ma elekitiromineti a mabodi osanjikiza ndi matabwa owiritsa kwambiri ayamba kukhala otchuka kwambiri. Chifukwa chachikulu chochitira izi ndichakuti malo achizindikiro kwambiri ndi ochulukirapo, omwe sikuti amangotulutsa radiation yamphamvu yamagetsi, komanso imapangitsa kuti madera azilumikizana ndi zosokoneza zakunja. Kuwongolera ma elekitromaagnetic kugwirizana, njira yosavuta ndiyo kuchepetsa malowa a chizindikiro chachikulu.

Chizindikiro Chofunikira: Kuchokera pakuwona kwa mawonekedwe a elekitomic, signals makamaka amatanthauza zizindikiro zomwe zimapanga ma radiation amphamvu ndi zizindikilo zakunja. Zizindikiro zomwe zimatha kupanga ma radiation amphamvu nthawi zambiri zimakhala zosafunikira, monga zizindikiro zotsika kwambiri mawotchi kapena ma adilesi. Zizindikiro zomwe zimakhudzidwa ndi kulowererapo ndi ma andalog zizindikiro ndi milingo yotsika.

Ma boloni osakwatiwa ndi awiri omwe amagwiritsidwa ntchito kawirikawiri nthawi zambiri amagwiritsidwa ntchito pamapangidwe otsika a Analog otsika pansi 10khz:
1) Mphamvu zomwe zimapangitsa kuti womwe ukhale womwewo umathamangitsidwa kwambiri, ndipo kutalika kwa mizerewo sikuchepetsedwa;

2) Mukamayendetsa mphamvu ndi mawaya pansi, ayenera kuyanjana wina ndi mnzake; Ikani waya wapansi mbali ya waya ndi waya wofunikira, ndipo waya wapansi uwu uyenera kukhala pafupi ndi waya wa siginecha. Mwanjira imeneyi, malo ocheperako amapangidwa ndipo chidwi cha ma radiation osiyanasiyana pakusokoneza kwa kunja kumachepetsedwa. Pamene waya wapansi umawonjezeredwa pafupi ndi waya wa siginecha, kuzungulira ndi dera laling'ono kwambiri kumapangidwa. Chizindikiro chazomwe zilipo chimakhala ndi chiwombacho m'malo mwa mawaya ena pansi.

3) Ngati ndi bolodi yosanjikiza madera awiri, mutha kuyikira waya wapansi pamzere wina wa chizindikiro mbali inayo, pomwepo pansi pa chingwe chamadera, ndipo mzere woyamba uyenera kukhala wotheka. Malo omwe amapezeka mwanjira imeneyi ndi wofanana ndi kukula kwa kukula kwa madera ochulukitsidwa ndi kutalika kwa mzere wa chizindikiro.

Awiri ndi anayi-tsindse amayamba
1. Sig-Gnd (PWR) -pwr (GND) -Sig;
2. Gnd-sig (pwr) -sig (pwr) -GND;

Kwa mapangidwe awiri omwe ali pamwambawa, vuto lomwe lingakhale lazachikhalidwe cha 1.6mm (62mil) bolodi. Kusanjikizako kudzakhala kwakukulu kwambiri, komwe sikosavuta kuwongolera zoletsa, zokhudzana ndi kugwirizanitsa ndi kutchinga; Makamaka kutalika kwakukulu pakati pa ndege zamphamvu kumachepetsa mphamvu ya board ndipo sikugwirizana ndi kusefa phokoso.

Kwa chiwembu choyamba, nthawi zambiri limagwiritsidwa ntchito pamkhalidwe pomwe pali tchipisi tambiri pa bolodi. Matendawa amatha kukhala ndi magwiridwe abwino a SI, siabwino kwambiri kwa EMI, ayenera kuwongolera ndi zowonera ndi zina zambiri. Chachikulu chisamaliro: nthaka yosanjikiza imayikidwa pa cholumikizira cholumikiza cha chizindikiro cha siginecha ndi chizindikiro chowiringa, chomwe chimapindulitsa kuyamwa ndikusokoneza ma radiation; Onjezani dera la bolodi kuti muwonetse ulamuliro wa 20h.

Pa njira yachiwiri, nthawi zambiri imagwiritsidwa ntchito pomwe chipata cha chip chimakhala chotsika ndipo pali malo okwanira kuzungulira chip (Ikani mphamvu yofunika ya mkuwa). Mu chiwembuchi, kusanjikiza kunja kwa PCB ndi malo osanjikiza, ndipo zigawo zikuluzikulu ziwiri ndi zigawo zikuluzikulu / zamagetsi. Magetsi opezeka pa signal wosanjikiza amasunthika ndi mzere waukulu, womwe umatha kupangitsa kuti njirayo igwetsere mphamvu yotsika kwambiri, ndipo kugwedeza njira ya signasi ya microstrip kulinso kochepa, ndipo magetsi amkati amatetezedwa ndi osanjikiza akunja. Kuchokera pakuwona kwa EMI kuwongolera, iyi ndiye njira yabwino kwambiri ya 4-tsabola.

Chachikulu chisamaliro: mtunda pakati pa zigawo ziwiri za chizindikiro ndi mphamvu zosakanikirana ziyenera kukulitsidwa, ndipo njira yolowera iyenera kukhala yosiyana kuti ipewe ma crostalsk; Malo a board ayenera kulamuliridwa moyenera kuti awonetse ulamuliro wa 20h; Ngati mukufuna kuthana ndi vuto la kuwonda, yankho lembali liyenera kusamala kwambiri kuti muone mawaya omwe adakonzedwa pansi pa chilumba cha mkuwa kuti chikhale mphamvu ndi zifukwa. Kuphatikiza apo, mkuwa pa magetsi kapena nthaka ayenera kuphatikizidwa momwe mungathere kuonetsetsa kuti dc ndi pang'ono kulumikizana pafupipafupi.

Atatu, asanu ndi limodzi-osanjidwa
Kwa mapangidwe okhala ndi kachulukidwe kakang'ono kwambiri komanso kaduka kakang'ono, kapangidwe ka 6 koloko ziyenera kuganiziridwa, ndipo njira yokhazikika ikulimbikitsidwa:

1. Sig-Gnd-sig-pwr-gand-sig;
Kwa chiwembu chotere, mtundu uwu womwe unakondwera nawo ungakhale ndi umphumphu, chizindikirocho chimakhala choyandikana ndi nthaka yosanjikiza, malo osanjikiza iliyonse amatha kuwongolera, ndipo ma stratum amatha kuyamwa mizere yamagalasi. Ndipo pamene magetsi amphamvu ndi malo osanjikiza ali okhwima, amatha kupereka njira yobwezera bwino kwa osanjikiza aliyense.

2. Gnd-siG-GMN-PWR-sig -gnd;
Kwa chiwembu chotere, chiwembu choterechi ndi choyenera kwa zomwe zimapangitsa kuti kuchuluka kwa chipango sikuli bwino kwambiri, ndipo ndege yamtunduwu imakhala ndi zabwino zonse zakumatambo ndi pansi. Tiyenera kudziwa kuti mphamvu zamphamvu ziyenera kukhala pafupi ndi wosanjikiza zomwe si malo akuluakulu, chifukwa ndege yotsika idzakhala yathunthu. Chifukwa chake, magwiridwe a EMI ndiwabwino kuposa yankho loyamba.

Chidule: Kwa thabwa lamasamba asanu ndi limodzi, mtunda pakati pa mafuta amphamvu ndipo nthaka iyenera kuchepetsedwa kuti ipeze mphamvu yabwino ndi kulumikizana. Komabe, ngakhale makulidwe a bolodi ndi 62mil ndipo nthawi yochepa imachepetsedwa, sikophweka kuwongolera kutalikirana pakati pa magetsi akulu ndi nthaka yochepa kwambiri. Kuyerekezera chiwembu choyamba ndi chiwembu chachiwiri, mtengo wa chiwembu chachiwiri chidzakula kwambiri. Chifukwa chake, nthawi zambiri timasankha njira yoyamba ikamayala. Mukamapanga, tsatirani ulamuliro wa 20H ndi kapangidwe kake kalozera.

Zinayi ndi zisanu ndi zitatu-zisanu zimayamba
1. Uwu si njira yabwino yokhomera chifukwa cha ma elekitikiti osavomerezeka a electromagnetic ndi ponseponse. Kapangidwe kake ndi izi:

Momwe Mungasankhire Matabwa angati omwe amagwiritsidwa ntchito popanga ndi momwe mungawapangire zimatengera zinthu zambiri monga kuchuluka kwa ziwerengero za zizindikiro za maukonde, kachulukidwe kakang'ono, kaphiri kake, kabati, kabatizi ndi zina zotero. Pazinthu izi, tiyenera kuganizira mozama. Pazizindikiro zodziwika bwino, kuchuluka kwa chipaso cha chipangizocho, kuchuluka kwa chipaso cha chikhomo ndi kuchuluka kwa zikwangwani, kapangidwe kake kaamalo kumayenera kutengera momwe angathere.
