Chifukwa cha kusintha kwa magetsi osinthira, ndikosavuta kuyambitsa mphamvu yosinthira mphamvu kuti apange zododometsa zabwino za electromagnetic. Monga injiniya wamagetsi, mainjiniya ophatikizika, kapena mainjiniya a PCB, muyenera kumvetsetsa zomwe zimayambitsa chifukwa cha zovuta za electromagnetic ndipo mwatsimikiza, makamaka mainjiniya ayenera kudziwa kukula kwa malo onyansa. Nkhaniyi imayambitsa mfundo zazikuluzikulu za kapangidwe ka magetsi PCB.
1. Mfundo zingapo zoyambira: Waya aliyense ali ndi vuto; zamakono nthawi zonse zimasankha njira yovuta kwambiri; Kukhazikika kwa radiation kumakhudzana ndi zochitika zamakono, pafupipafupi, komanso malo otupa; Kuphatikizidwa wamba kumakhudzana ndi kuchuluka kwa ma cv / dt kumayiko ena. Mfundo yochepetsera EMI ndikuwonjezera luso lomwe limatha kusokoneza ndizofanana.
2. Masankhidwewo ayenera kugawidwa malinga ndi kuchuluka kwa mphamvu, analog, ma digito othamanga kwambiri ndi chipika chilichonse.
3. Chepetsa dera la DI / DT Laop ndi kuchepetsa kutalika (kapena dera, m'lifupi mwa mzere waukulu wa DV / DT. Kuchuluka kwa malo oyendera kumawonjezera mwayi wogawika. Njira yayikuluyi ndi iyi: Tsimikizani m'lifupi mwake momwe mungathere, koma chotsani gawo lonse), ndipo yesani kuyenda mumzere wowongoka kuti muchepetse malo obisika kuti muchepetse ma radiation.
4. Crostation Crostalk makamaka amayambitsidwa ndi chiuno chachikulu cha di / DT (loop Anterna), ndipo kukula kwake ndikofunikira kuti muchepetse kusinthika, motero ndikofunikira kuti muchepetse malowa ndikuwonjezera mtunda); Kugonana kumapangidwa ndi zizindikiro zazikulu dv / dt, ndipo kulimba mtima kwakukulu ndikofanana ndi kuthekera. Makina onse ogwirizana ndi zizindikirozi amachepetsedwa (njira yayikulu ndikuchepetsa malo ophatikizira ndikuwonjezera mtunda. Makina osokoneza bongo amachepetsa.
5. Yesani kugwiritsa ntchito mfundo za kuletsa kwa Loop kuti muchepetse gawo la DI / DT Laop, monga taonera Chithunzi 1 (ofanana ndi awiri opindika
Gwiritsani ntchito mfundo zothetsera vuto kuti musinthe luso lothana ndi kugwiritsira ntchito ndikuwonjezera mtunda wopitilira):
Chithunzi 1, kuchotsera msonkho (loop lotuta)
6. Kuchepetsa malowo osati kumachepetsa radiation, komanso kumachepetsa kulangidwa, kumapangitsa mabizinesi kukhala bwino.
7. Kuchepetsa malowa kumafunikira kuti tisatulutse molondola njira yobwezera iliyonse.
8. Ndibwino kuti waya umodzi wowoneka bwino umafanana ndi waya umodzi, ndipo mawaya awiriwo ali pafupi kwambiri momwe angathere. Ngati ndi kotheka, maaya opindika amatha kugwiritsidwa ntchito polumikizana (kutalika kwa seya iliyonse yopotoza ikufanana ndi kuchuluka kwa phokoso laphokoso). Ngati mutsegula milandu ya pakompyuta, mutha kuwona kuti mawonekedwe a USB pakati pa bolodi ndi gulu lakutsogolo limalumikizidwa ndi awiri opindika, omwe akuwonetsa kufunikira kwa kulumikizana kwa anti-kusokoneza.
9. Pa chingwe cha data, yesani kukonza zingwe zochulukitsa mu chingwe, ndikupanga mawaya ake pansi pomwe amagawidwa moyenera mu chingwe, chomwe chimatha kuchepetsa malowa.

12. Kusintha magetsi nthawi zambiri kumakhala ndi malupu 4: Kulowetsa, kusintha, kuzizira, (Chithunzi 2). Pakati pawo, zoyambitsa ndi kutulutsa malupu ndi pafupifupi kuwongolera, pafupifupi palibe EMI omwe amapangidwa, koma amasokonezeka mosavuta; Kusinthana ndi kusuntha kwa malupu omwe ali ndi vuto lalikulu di / DT, zomwe zimafunikira chisamaliro.
Chithunzi 2, loops waposachedwa
