4 Umaleko FR4 OSP Impedance Control PCB
Iimpawu zoLawulo lwe-PCB
Ukuphazamiseka kweempawu zomqhubi kwi-PCB sisalathiso esibalulekileyo soyilo lwesekethe, ngakumbi kwi-PCB yoyilo lwesekethe ye-frequency frequency, kufuneka siqwalasele ukuba i-impedance ye-conductor iyahambelana ne-impedance yeempawu ezifunwa sisixhobo okanye umqondiso.
PCB Imedance Matching
Kwi-PCB, ukuba kukho ukuhanjiswa komqondiso, kulindeleke ukuba isuke ekupheleni kokuthumela unikezelo lwamandla, kwimeko yelahleko encinci yamandla, inokuhanjiswa ngokutyibilikayo ukuya ekupheleni kokufumana, kwaye isiphelo sokufumana siya kutsalwa ngokupheleleyo. ngaphandle kokucinga.Ukufezekisa oku kuhanjiswa, i-impedance kumgca kufuneka ilingane ne-impedance ngaphakathi kwesiphelo sokuqala ukuba kubizwe i-impedance matching.Ukuthelekisa i-Impedans yenye yezinto zoyilo xa kuyilwa isantya esiphezulu sesekethe yePCB.Ixabiso le-impedance linxulumene ngokupheleleyo nemowudi yomzila.
Umzekelo, nokuba uhamba kumaleko womphezulu (Microstrip) okanye umaleko wangaphakathi (i-Stripline/Double Stripline), umgama ukusuka kumandla ereferensi okanye umaleko, ububanzi bendlela, imathiriyeli yePCB, njl. indlela.Oko kukuthi, ixabiso le-impedance linokumiselwa kuphela emva kwe-wiring, kwaye i-impedance yeempawu eziveliswa ngabavelisi be-PCB abahlukeneyo nabo bahluka kancinci.Ngokuqhelekileyo, isofthiwe yokulinganisa ayiyi kukwazi ukuqwalasela i-impedance discontinuous wiring ngenxa yokunciphisa imodeli yomgca okanye i-algorithm yemathematika esetyenzisiweyo.
Ngeli xesha, kuphela i-Temninators ethile enokugcinwa kumzobo weskimu, njengokumelana nothotho, ukunciphisa isiphumo sokuyeka ukunyanzelwa kweengcingo.Esona sisombululo sisisiseko kwingxaki kukuzama ukunqanda ukwenzeka kwe-impedance discontinuity xa i-wiring.
