I-RF PCB - Amabhodi Esekethe Aphrintiwe KumaRadio Frequency. Ngokuvamile, imboni ye-PCB ibheka ibhodi lesifunda le-RF njenganoma iyiphi i-PCB yemvamisa ephezulu esebenza ngaphezu kwe-100MHz.
Ngaphakathi kwesigaba semvamisa yomsakazo, noma yini engaphezulu kwe-2GHz yi-Microwave PCB. Abayisebenzisayo. Ama-PCB e-Microwave ahlukaniswa njenganoma yiliphi ibhodi lesifunda le-RF elisebenza ngaphezu kwe-2GHz.
Amabhodi wesifunda e-RF nama-Microwave PCBs asetshenziselwa amasiginali wokuxhumana kunoma yiluphi uhlelo lokusebenza oludinga ukwamukela nokudlulisa amasiginali omsakazo. Isibonelo, ezinye izinhlelo ezijwayelekile kungamaselula nokufakwa kwe-radar.Abanye babahlinzeki bezinto ezinama-laminate / dielectric esizisebenzisayo yilezi: Isola, Nelco, Rogers & Taconic.
Ibhodi yesifunda ephrintiwe eyi-hybrid (PCB) multilayer iyi-PCB esebenzisa izinto ezihlukile ngenhloso yokwenza ngcono ukusebenza kukagesi nokwenza ngcono ukuthembeka kohlelo okugxile kuzinhlelo zokusebenza ze-RF ezinemvamisa ephezulu. Inselelo enkulu lapho kwenziwa lolu hlobo lwe-PCB ukuphatha ukulingana okuhlukile kokunwetshwa okushisayo (CTE) izakhiwo zezinto zesifunda ezingafani zombili ngesikhathi se-PCB bumbela nomhlangano wezinto.
Imvamisa le miklamo ifaka inhlanganisela yezinto ezinamathele e-FR-4 kanye ne-PTFE evumela umklami ukuthi anciphise ukusebenza kwe-RF nokusebenza kwe-RF ku-PCB efanayo enganciphisa zombili izingqimba zedivayisi nezindleko.
