Kubvisa electromagnetic interference (EMI) kubva kuPCB (yakadhindwa redunhu bhodhi) dhizaini inogona kuve yakaoma uye inoda matanho akati wandei.Mamwe ematanho akanyanya kukosha aya ndeaya anotevera:
Ziva zvinogona kuwanikwa zveEMI:
Danho rekutanga mukubvisa EMI ndere kuona zvingangoitika zvekukanganisa.Iyi nhanho inosanganisira kutarisa dhizaini chimiro uye kuona zvinhu senge oscillator, switching regulators uye masaini edhijitari anowanzo gadzira EMI.
Optimize chikamu kuiswa:
Kuisa zvikamu paPCB zvinovapa mukana wakanaka.Kudzivirira kana kusefa zvinhu kunobatsira kutsaura masekete ane hunyoro, kana ungangoda kufambisa zvinhu kutenderedza kuti uderedze nzvimbo iri pakati pawo.
1. Shandisa nzira dzekugadzirisa pasi
Kuisa pasi kwakakosha kuderedza EMI.Kuti uderedze mukana weEMI unofanirwa kushandisa nzira chaiyo yekumisa pasi.Iyi nhanho inosanganisira kushandisa ndege yepasi yakatsaurirwa kugovera zviratidzo zveanalogue uye digital, kana kubatanidza zvikamu zvakawanda kune imwe ndege yepasi.
2. Shandisa kudzivirira uye kusefa
Mune zvimwe zviitiko, zvikamu zvinoshandiswa kudzivirira kana kusefa zvinogona kubatsira kubvisa EMI.kusefa zvikamu zvinobatsira kubvisa zvisingadiwe frequencies kubva pachiratidzo, nepo kudzivirira kunogona kubatsira kudzivirira EMI kuti isasvike masekete ane tsitsi.
3. Kuedzwa uye kusimbiswa
Mushure mekunge dhizaini yagadziriswa, unofanirwa kuve nechokwadi kuti wabvisa EMI nemazvo.kubviswa uku kungangoda kuyera kuburitswa kwePCB nemagetsi neEMI analyser, kana kuyedza PCB mumamiriro ezvinhu epasirese kuti ive nechokwadi chekuti inoshanda sezvakarongwa.
Kuedza EMI muPCB magadzirirwo
Iwe unofanirwa kuyedza iyo EMI muPCB dhizaini yako uye kana zvirizvo, saka zvinotevera zvinofanirwa kukubatsira iwe kutenderera.Mushure meizvozvo, iwe uchada kutevedzera nhanho dzinotevera:
1. Tsanangura maitiro ekuedzwa
Tsanangura iyo frequency renji, nzira dzekuyedza uye miganhu.Muyero wechigadzirwa unofanirwa kusarudza maitiro ekuyedza.
2. Midziyo yekuedza
Gadzira EMI inogamuchira, chiratidzo jenareta, spectrum analyzer uye oscilloscope.Midziyo yacho inofanirwa kuverengerwa uye kuongororwa isati yaedzwa.
3. Gadzirira PCB
Nezvinangwa zvekuyedza, ita shuwa kuti waisa zvese zvikamu nemazvo uye simba PCB nemazvo nekuibatanidza nemidziyo yekuyedza.
4. Ita bvunzo yeradiated emission
Kuita bvunzo yeradiated emission, isa PCB mukamuri yeanechoic uye tumira chiratidzo nejenareta rechiratidzo uchiyera mwero weradiated emission neEMI inogamuchira.
5. Yakaitwa emission test
Yakaitwa bvunzo yekuburitsa nekupinza masaini musimba uye masaini mitsara yePCB, uku ichiyera yakaitwa emission level neEMI inogamuchira.
6. Ongorora zvabuda
Ongorora mhinduro dzebvunzo kuti uone kana PCB dhizaini inosangana nemiyedzo yebvunzo.Kana mhedzisiro yebvunzo ikasasangana nemaitiro, ratidza kwainobva zvinobuda uye tora matanho ekugadzirisa, sekuwedzera EMI kudzivirira kana kusefa.
Profile yekambani
Zhejiang NeoDen Technology Co., Ltd. yave kugadzira nekutumira kunze michina midiki yakasiyana-siyana yekunhonga nenzvimbo kubva muna 2010. Tichitora mukana weR&D yedu yakapfuma ine ruzivo, kugadzirwa kwakanyatsodzidziswa, NeoDen inohwina mukurumbira mukuru kubva kuvatengi vepasi rose.
nekuvapo kwepasirese munyika dzinopfuura zana nemakumi matatu, kuita kwakanakisa, kunyatsoita uye kuvimbika kweNeoDen PNP michina inoita kuti ive yakakwana yeR&D, prototyping yehunyanzvi uye diki kusvika pakati batch kugadzirwa.Isu tinopa nyanzvi mhinduro yeimwe yekumira SMT michina.
