Ho tlosa tšitiso ea motlakase (EMI) ho PCB (boto ea potoloho e hatisitsoeng) ho ka ba thata mme ho hloka mehato e mengata.E meng ea bohlokoa ka ho fetisisa ea mehato ena ke e latelang:
Hlalosa mehloli e ka bang teng ea EMI:
Mohato oa pele oa ho felisa EMI ke ho tseba mehloli e ka bang teng ea tšitiso.Mohato ona o kenyelletsa ho sheba sebopeho sa potoloho le ho khetholla likarolo tse kang li-oscillator, li-switching regulators le matšoao a dijithale a atisang ho hlahisa EMI.
Ntlafatsa ho beoa ha likarolo:
Ho beha likarolo ho PCB ho ba fa molemo ka ho fetisisa.Likarolo tse sireletsang kapa tsa ho sefa li thusa ho arola li-circuits tse hlokolosi, kapa ho ka 'na ha hlokahala hore u tsamaise likarolo ho pota-pota ho fokotsa sebaka se pakeng tsa tsona.
1. Sebelisa mekhoa e nepahetseng ea motheo
Ho beha fatše ho bohlokoa ho fokotsa EMI.Ho fokotsa monyetla oa EMI o lokela ho sebelisa mokhoa o nepahetseng oa ho thea.Mohato ona o kenyelletsa ho sebelisa sefofane sa fatše se inehetseng ho arola lipontšo tsa analogue le tsa digital, kapa ho hokahanya likarolo tse ngata ho sefofane se le seng sa fatše.
2. Kenya ts'ebetsong ho sireletsa le ho sefa
Maemong a mang, likarolo tse sebelisetsoang ho sireletsa kapa ho sefa li ka thusa ho felisa EMI.likarolo tsa ho sefa li thusa ho tlosa maqhubu a sa batleheng ho tloha lets'oao, ha ts'ireletso e ka thusa ho thibela EMI ho fihla lipotolohong tse bobebe.
3. Teko le netefatso
Kamora hore moralo o ntlafatsoe, o tlameha ho etsa bonnete ba hore o felisitse EMI ka nepo.pheliso ena e ka hloka ho lekanya likhase tsa motlakase tsa PCB ka mohlahlobi oa EMI, kapa ho lekola PCB maemong a lefats'e la nnete ho netefatsa hore e sebetsa joalo ka ha ho reriloe.
Ho leka EMI ka meralo ea PCB
Na u hloka ho leka EMI moralong oa hau oa PCB mme haeba ho joalo, lintlha tse latelang li lokela ho u thusa ho potoloha.Ka mor'a moo, u tla batla ho latela mehato e latelang:
1. Hlalosa litekanyetso tsa teko
Hlalosa mofuta oa maqhubu, mekhoa ea liteko le meeli.Tekanyetso ya sehlahiswa e lokela ho supa maemo a teko.
2. Lisebelisoa tsa teko
Theha moamoheli oa EMI, jenereithara ea matšoao, analyzer ea spectrum le oscilloscope.Thepa e lokela ho lekanyetsoa le ho netefatsoa pele ho tlhahlobo.
3. Lokisetsa PCB
Bakeng sa merero ea tlhahlobo, etsa bonnete ba hore o kenya likarolo tsohle ka nepo le ho matlafatsa PCB ka nepo ka ho e hokahanya le lisebelisoa tsa tlhahlobo.
4. Etsa tlhahlobo ea mahlaseli a kotsi
Ho etsa tlhahlobo e hlahisoang ke mahlaseli a kotsi, beha PCB ka phaposing ea anechoic 'me u fetise lets'oao ka jenereithara ea mats'oao ha u ntse u lekanya boemo ba mocheso o tsoang ka moamoheli oa EMI.
5. Ho etsoa teko ea tlhahiso
E entsoe tlhahlobo ea tlhahiso ka ho kenya matšoao matleng le methapong ea mats'oao a PCB, ha e ntse e lekanya boemo ba phallo e tsamaisoang le moamoheli oa EMI.
6. Sekaseka liphello
Sekaseka liphetho tsa liteko ho fumana hore na moralo oa PCB o kopana le litekanyetso tsa tlhahlobo.Haeba liphetho tsa liteko li sa fihlelle litekanyetso, hloaea mohloli oa mesi ebe u nka khato ea ho lokisa, joalo ka ho kenya tšireletso ea EMI kapa ho sefa.
