Sankhani kusefa kwa EMI pama board amitundu yambiri kuti muchepetse kusokoneza

Momwe mungasankhire ukadaulo wama electromagnetic radiation ndi EMI kusefa koyenera matabwa amitundu yambiri kuti muchepetse kusokoneza kwa zida ndi machitidwe ena

Chiyambi:

Pomwe zovuta za zida zamagetsi zikupitilira kukula, nkhani za electromagnetic interference (EMI) zakhala zofunika kwambiri kuposa kale. EMI imatha kusokoneza magwiridwe antchito amagetsi ndikuyambitsa kulephera kapena kulephera. Kuti athane ndi vutoli, ukadaulo wama electromagnetic radiation ndi EMI kusefa ndizofunikira pama board ambiri. Mu positi iyi yabulogu, tikambirana momwe tingasankhire ukadaulo woyenera kuti muchepetse kusokonezeka kwa zida ndi makina ena.

1. Kumvetsetsa mitundu yosiyanasiyana ya kusokoneza:

Musanalowe m’chisankho, m’pofunika kumvetsa bwino za mitundu yosiyanasiyana ya zosokoneza. Mitundu yodziwika bwino imaphatikizapo EMI, radiated EMI, ndi transient EMI. EMI yoyendetsedwa imatanthawuza phokoso lamagetsi lomwe limayendetsedwa kudzera mumagetsi kapena ma siginecha. Radiated EMI, kumbali ina, ndi mphamvu yamagetsi yochokera ku gwero. Transient EMI imaphatikizapo magetsi adzidzidzi kapena ma spikes apano. Kuzindikira mtundu weniweni wa kusokoneza komwe mukukumana nako kudzakuthandizani kuchepetsa teknoloji yoyenera yosefera.

2. Dziwani kuchuluka kwa ma frequency:

Zida zamagetsi zosiyanasiyana zimagwira ntchito mosiyanasiyana. Chifukwa chake, ndikofunikira kudziwa kuchuluka kwa ma frequency omwe kusokoneza kumachitika. Chidziwitsochi chithandiza posankha njira zosefera zoyenera zomwe zimagwirizana ndi kusokoneza pafupipafupi. Mwachitsanzo, ngati kusokoneza kumachitika pafupipafupi, fyuluta ya band-pass ingakhale yoyenera, pamene kusokoneza kwafupipafupi kungafunike fyuluta yotsika.

3. Gwiritsani ntchito ukadaulo woteteza:

Kuphatikiza pa ukadaulo wosefera, ukadaulo woteteza ndi wofunikiranso kuti muchepetse kusokoneza. Kuyika zinthu zowoneka bwino kapena mabwalo okhala ndi zida zowongolera kungathandize kuletsa ma radiation a electromagnetic. Zitini zotchingidwa bwino kapena zotchingidwa ndi zitsulo zimagwiritsidwa ntchito nthawi zambiri. Posankha zotchinga zoyenera, ganizirani zinthu monga ma conductivity, makulidwe, komanso kumasuka kuphatikiza ma board a multilayer.

4. Fufuzani ukatswiri pakupanga ma board a multilayer:

Kupanga ma board a multilayer omwe amachepetsa kusokoneza kumafuna ukadaulo wamakonzedwe ndi njira zamanjira. Kugwira ntchito ndi katswiri wodziwa kupanga ma board amitundu yambiri kungathandize kuzindikira madera omwe angasokonezeke ndikuwongolera bwino masanjidwewo kuti achepetse nkhani ngati izi. Kuyika koyenera kwa zigawo, kulingalira kwa ndege pansi, ndi kuwongolera njira zolepheretsa ndi zina mwazinthu zomwe zimathandizira kupanga ma board a multilayer.

5. Yesani ndikutsimikizira:

Njira zosefera ndi njira zopangira zikakhazikitsidwa, ndikofunikira kuyesa ndikuwonetsetsa kuti yankho lomwe mwasankha likugwira ntchito. Kuyesa kutha kuchitidwa pogwiritsa ntchito cholandila cha EMI ndi spectrum analyzer kuyeza kuchuluka kwa kusokoneza komwe kulipo. Gawoli lithandiza kuzindikira zosintha zilizonse zomwe zingafunike ndikuwonetsetsa kuti ukadaulo wosankhidwa umachepetsa kusokoneza zida ndi machitidwe ena.

Powombetsa mkota

Kusankha njira zolondola zama electromagnetic radiation ndi njira zosefera za EMI pama board a multilayer ndikofunikira kuti muchepetse kusokoneza ndi zida zina. Kumvetsetsa mitundu yosokoneza, kudziwa mafupipafupi, kugwiritsa ntchito njira zotetezera, kufunafuna ukatswiri pakupanga ma board a multilayer, komanso kuyesa ndi kutsimikizira mayankho osankhidwa ndi njira zonse zofunika pakuchita izi. Potsatira malangizowa, mutha kuwonetsetsa kuti makina anu amagetsi akugwira ntchito bwino komanso odalirika pomwe mukuchepetsa zovuta zobwera chifukwa cha kusokoneza kwa EMI.
