2 Umaleko OSP F4B High Frequency PCB
Malunga F4B High Frequency PCB
I-Wangling F4B isekwe kwiimfuno zokusebenza kombane kwiisekethe ze-microwave,
Luhlobo lwebhodi yesekethe egqwesileyo yemicrowave eprintiweyo eneempawu ezilungileyo zombane kunye namandla omatshini aphezulu.
Uyilo lwe-F4B ePhakamileyo ye-PCB
Kuyilo lwe-PCB ye-high-frequency, abayili badla ngokunikela ingqalelo engakumbi kwi-dielectric constant (DK) kunye ne-tangent loss (DF) ye-PCB xa ukhetha izinto, kwaye ubeke ingqalelo kuphela kubunzima befoyile yobhedu xa ukhetha ifoyile yobhedu, eyifoyile yobhedu. kulula ukungayinaki impembelelo yeentlobo ezahlukeneyo zefoyile yobhedu kwiipropati zombane zeemveliso.
Uhlalutyo lwe-SEM ye-micro morphology yeentlobo ezahlukeneyo zefoyile yobhedu kunye ne-dielectric contact surface ibonisa ukuba uburhabaxa beentlobo ezahlukeneyo zefoyile yobhedu buhluke kakhulu.Ekuqulunqweni komgca we-microstrip, ubuninzi be-foil yethusi kunye ne-dielectric contact surface iya kuchaphazela ngokuthe ngqo ukulahleka kokufakwa komgca wokuhambisa wonke.
Iiparamitha zezinto zeF4B PCB
I-Wangling F4B yenziwe ngezinto ezikumgangatho ophezulu ngokweemfuno zokusebenza kombane kwiisekethe ze-microwave.Inokusebenza kakuhle kombane kunye namandla aphezulu omatshini.Yeyona bhodi yomgangatho wesiphaluka egqwesileyo ye-microwave eprintiweyo.Ubushushu obuqhelekileyo be-15N/cm obuhlala bumanzi kunye ne-260℃±2℃ fusion welding material ukugcina imizuzwana engama-20 ngaphandle kogwebu, akukho stratification kunye namandla okuxobula ≥12 N/cm.
