Sarudza EMI kusefa kune akawanda-layer mabhodhi kuderedza kupindira

Maitiro ekusarudza electromagnetic radiation uye EMI kusefa tekinoroji yakakodzera kune akawanda-layer mabhodhi kudzikisa kupindira kune zvimwe zvishandiso uye masisitimu.

Nhanganyaya:

Sezvo kuomarara kwemidziyo yemagetsi kuri kuramba kuchiwedzera, nyaya dzemagetsi (EMI) dzakanyanya kukosha kupfuura nakare kose. EMI inogona kukanganisa kuita kwemagetsi masisitimu uye kukonzera kusashanda kana kutadza. Kugadzirisa dambudziko iri, electromagnetic radiation uye EMI kusefa tekinoroji yakakosha kumabhodhi akawanda. Mune ino blog post, isu tichakurukura nzira yekusarudza iyo tekinoroji yakakodzera kuderedza kukanganisa kune mamwe maturusi nemasystem.

1. Nzwisisa mhando dzakasiyana dzekupindira:

Usati wanyura mukuita sarudzo, zvakakosha kuve nekunzwisisa kwakajeka kwemhando dzakasiyana dzekuvhiringidza. Mhando dzakajairwa dzinosanganisira inoitiswa EMI, radiated EMI, uye yenguva pfupi EMI. Kuitwa EMI kunoreva ruzha rwemagetsi rwunoitwa kuburikidza nemagetsi kana mitsara yemasaini. Radiated EMI, kune rumwe rutivi, isimba remagetsi rinoburitswa kubva kune sosi. Transient EMI inosanganisira kamwe kamwe magetsi kana maspikes azvino. Kusarudza iyo chaiyo mhando yekuvhiringidza iwe yauri kubata nayo inozobatsira kuderedza iyo yakakodzera kusefa tekinoroji.

2. Sarudza frequency renji:

Zvishandiso zvemagetsi zvakasiyana zvinoshanda pama frequency akasiyana. Naizvozvo, zvakakosha kuti uone kuti frequency renji inoitika kukanganiswa. Ruzivo urwu ruchabatsira mukusarudza nzira dzekusefa dzakakodzera dzinoenderana nekukanganisa frequency renji. Semuyenzaniso, kana kupindira kuchiitika pamatunhu akakwirira, bhandi-pass sefa ingave yakakodzera, nepo kupindira kwakaderera-frequency kungada sefa yepasi-pasi.

3. Shandisa tekinoroji yekudzivirira:

Pamusoro pekusefa tekinoroji, tekinoroji yekudzivirira yakakoshawo kudzikisa kupindira. Kuputira zvinhu zvinonzwisa tsitsi kana maseketi ane conductive zvinhu zvinogona kubatsira kuvharira magetsi emagetsi. Makoni akavharidzirwa kana simbi akavharidzirwa anowanzo shandiswa kuita izvi. Paunenge uchisarudza iyo chaiyo yekudzivirira zvinhu, funga zvinhu zvakaita se conductivity, ukobvu, uye kureruka kwekubatanidzwa mumabhodhi akawanda.

4. Tsvaga hunyanzvi mukugadzira bhodhi remultilayer:

Kugadzira mabhodhi akawanda anoderedza kupindira kunoda hunyanzvi mukurongeka uye nzira dzekufambisa. Kushanda nenyanzvi inyanzvi mune akawanda-layer board dhizaini kunogona kubatsira kuona dzingangove nzvimbo dzekuvhiringidza uye nekugadzirisa marongero kudzikisa nyaya dzakadai. Kuiswa kwakakodzera kwechikamu, kufunga kwendege yepasi, uye inodzorwa impedance routing ndezvimwe zvezvinhu zvakakosha zvinopa kune inoshanda multilayer board dhizaini.

5. Edzai uye simbisai:

Kana nzira dzekusefa nemaitiro ekugadzira zvaitwa, zvakakosha kuti uedze uye uone kushanda kwemhinduro yakasarudzwa. Kuedzwa kunogona kuitwa uchishandisa EMI inogamuchira uye spectrum analyzer kuyera huwandu hwekukanganisa huripo. Iyi nhanho ichabatsira kuona chero imwe gadziriso ingangodiwa uye kuona kuti tekinoroji yakasarudzwa inoderedza kuvhiringika kune mamwe maturusi uye masisitimu.

Muchidimbu

Kusarudza iyo chaiyo electromagnetic mwaranzi uye EMI kusefa matekiniki emabhodhi akawanda kwakakosha kudzikisa kukanganiswa nemimwe michina uye masisitimu. Kunzwisisa marudzi ekupindira, kuona ma frequency range, kushandisa nzira dzekudzivirira, kutsvaga hunyanzvi mukugadzira bhodhi re multilayer, uye kuyedza nekusimbisa mhinduro dzakasarudzwa ese matanho akakosha mukuita uku. Nekutevera aya madhiraivha, unogona kuve nechokwadi chekuita kwakakwana uye kuvimbika kweako emagetsi masisitimu uku uchidzikisa mhedzisiro yekukanganisa kweEMI.
