Ama-frequency e-Radio (RF) ama-PCB nama-microwave PCB angatholakala kwimikhiqizo engenazintambo kusuka kumadivayisi aphathwayo wezicelo zezokwelapha nezimboni kuzinhlelo zokuxhumana ngocingo zeziteshi ezisezingeni eliphansi, i-radar nezinhlelo zokubeka umhlaba wonke.
Into ebaluleke kakhulu ekukhiqizeni ama-PCBs omsakazo ukulawula amasiginali kusetshenziswa (i) izinhlobo zezinto ezibonakalayo nezinto ezibonakalayo (i-loss tangent / Df kanye ne-dielectric njalo / iDkt) (ii) ama-foils wephrofayili ophansi (iii) izitayela zokuluka kanye (iv) kanjani sihlela izifunda zethusi, njengoba zonke lezi zinto zinomthelela omkhulu ekusebenzeni komkhiqizo ophelile.
Kumasekethe ePandawill, sinezinhlobonhlobo zama-laminate wezinketho zakho.
● I-RO3003: I-Dk ye-3.00 +/- .04
● I-RO4003C: UDkt ka-3.38 +/- 0.05
● I-RO4350B: I-Dk ye-3.48 +/- 0.05
● FR408HR: Dk ka-3.68, tg190
● FR408: Dk ka-3.67, tg180
● I-TU-872 LK: UDkt ka-3.8
● I-TU-872 SLK Sp: UDkt ka-3.5
Futhi kuyatholakala
10 ungqimba Izinto: Rogers RO3003; ukujiya kwebhodi 1.6MM, ukuphela kwe-Surface: Ukucwiliswa kwesiliva
Isicelo: Ingqalasizinda engenantambo ye-5G
2 ungqimba Izinto: RO3003, ibhodi ukujiya: 0.4mm ukujiya, indawo yokuqedela: ukucwiliswa isiliva
4 ungqimba, Izinto: 1-2 ungqimba RO3003 + 3-4 ungqimba Isola 370HR, ibhodi ukujiya 1.6MM
Surface sekugcineni: Ukucwiliswa isiliva
