Kana zvasvika kune impedance, mainjiniya mazhinji ane matambudziko mazhinji nazvo.Nekuti kune akawanda machinjiro anokanganisa kukosha kweinodzorwa impedance mune yakadhindwa redunhu bhodhi, zvisinei, chii chinonzi impedance uye chii chatinofanira kufunga kana ichidzorwa impedance?
Tsanangudzo yeImpedance?
Impedance ihuwandu hwekupikisa uye kuita kwedunhu remagetsi rinoyerwa muOhms.Impedance inotsinhanisa yazvino hunhu umo chiratidzo frequency chinhu chakakosha.Iyo yakareba kuteedzera kana kukwirisa frequency, zvinonyanya kukosha kudzora trace impedance.Signal frequency chinhu chakakosha chetrace inobatanidza kune zvikamu zvinoda mazana maviri kusvika matatu MHz kana kupfuura.
Zvizhinji zvakasiyana-siyana zvekutevera zvigadziriso zvaizoshandiswa mumabhodhi akadhindwa edunhu kuti awane inodzorwa impedance.Isu tinokwanisa kudzora iyo impedance kuburikidza nekupatsanura uye zviyero zveyedunhu bhodhi traces.
Impedance Control Level iripo
Kazhinji, kune matatu mazinga e impedance control anowanikwa kune akadhindwa edunhu mabhodhi.
1. Impedance Control
Impedance control inoshandiswa zvakanyanya mumagadzirirwo epamusoro-soro ane kushivirira kwakasimba kana kusajairika kumisikidzwa.Kune akati wandei akasiyana marudzi ekudzora impedance.Mune iyo hunhu impedance inowanzoshandiswa.Mamwe marudzi anosanganisira wave impedance, mufananidzo impedance, uye impedance yekupinza.
2. Impedance Kutarisa
Impedance Kutarisa zvinoreva kuenderana mune impedance.Iyo impedance control trace ichatemwa nehupamhi hwekuteedzera uye kureba kweiyo dielectric, iyo inogona kugadziriswa sezvinodiwa.
3. Hapana Impedance Control
Nekuti iyo impedance kushivirira mudhizaini haina kusimba, chaiyo impedance inogona kuwanikwa nekuenderana neyakajairwa yakatarwa pasina impedance control.chaiyo impedance inogona kupihwa nePCB mugadziri pasina mamwe matanho, Saka, ndiyo yakanyanya kudhura-inoshanda mwero.
Kukosha Kwechokwadi kune impedance control
Kukosha kwekurongeka kwakakosha zvakanyanya kuti controlled impedance boards ishande nemazvo.nekuti vagadziri vePCB vanofanirwa kutsanangura trace impedance uye kushivirira kunodiwa.
Mimwe mibvunzo nezve impedance control, unogona kubvunza timu yeinjiniya muPHILIFAST, ivo vanokupa mhinduro yakanaka nezve PCB yako mabhodhi.
