2 Isendlalelo se-OSP F4B Imvamisa ephezulu PCB
Mayelana ne-F4B High Frequency PCB
I-Wangling F4B isuselwe ezidingweni zokusebenza kukagesi zamasekethe e-microwave,
Iwuhlobo lwebhodi lesifunda eliphrintiwe le-microwave elihle kakhulu elinezindawo ezinhle zikagesi namandla aphezulu okusebenza.
Idizayini ye-F4B High Frequency PCB
Ekwakhiweni kwe-PCB enemvamisa ephezulu, abaklami bavame ukunaka kakhulu i-dielectric constant (DK) kanye nokulahleka kwe-tangent (DF) ye-PCB lapho bekhetha izinto zokwakha, futhi banake kuphela ubukhulu befoyili yethusi lapho bekhetha ucwecwe lwethusi, kulula ukungazinaki ithonya lezinhlobo ezahlukene ze-foil yethusi emangelengele ezindaweni zikagesi zemikhiqizo.
Ukuhlaziywa kwe-SEM ye-micro morphology yezinhlobo ezahlukene zefoyili yethusi kanye nendawo yokuthintana ye-dielectric kukhombisa ukuthi ukuhwaqa kwezinhlobo ezahlukene zefoyili yethusi kuhluke kakhulu.Ekwakhiweni kolayini we-microstrip, ukugwedla kwe-copper foil kanye ne-dielectric contact surface kuzothinta ngokuqondile ukulahlekelwa kokufaka kwawo wonke umugqa wokudlulisela.
Amapharamitha wezinto ze-F4B PCB
I-Wangling F4B yenziwe ngezinto ezisezingeni eliphezulu ngokuya ngezidingo zokusebenza zikagesi zamasekethe ama-microwave.Isebenza kahle kagesi namandla aphezulu emishini.Kuyibhodi elingaphansi lesifunda eliphrintiwe le-microwave elihle kakhulu.Ukushisa okuswakeme okujwayelekile okungu-15N/cm kanye nezinto zokushisela ezihlanganisiwe ezingu-260℃±2℃ ukuze kugcinwe imizuzwana engu-20 ngaphandle kokukhihliza amagwebu, akukho stratification namandla okuxebuka ≥12 N/cm.
