Koresha Customer 2-PTFE PCB

Muri rusange, inshuro nyinshi zishobora gusobanurwa nkinshuro iri hejuru ya 1GHz. Kugeza ubu, ibikoresho bya PTFE bikoreshwa cyane mubikorwa byo hejuru bya PCB, byitwa kandi Teflon, ubusanzwe buri hejuru ya 5GHz. Uretse ibyo, FR4 cyangwa PPO substrate irashobora gukoreshwa kumurongo wibicuruzwa muri 1GHz ~ 10GHz. Izi ntera eshatu zo hejuru zifite itandukaniro riri munsi:

Kubijyanye nigiciro cya laminate ya FR4, PPO na Teflon, FR4 nimwe ihendutse cyane, naho Teflon nimwe ihenze cyane. Kubijyanye na DK, DF, kwinjiza amazi nibiranga inshuro, Teflon nibyiza. Mugihe ibicuruzwa bisaba ibicuruzwa hejuru ya 10GHz, gusa dushobora guhitamo Teflon PCB substrate yo gukora. Imikorere ya Teflon ni nziza cyane kurenza iyindi substrate, Nyamara, Substrate ya Teflon ifite ibibi byigiciro kinini hamwe numutungo munini urwanya ubushyuhe. Kunoza imikorere ya PTFE hamwe nubushobozi bwumutungo urwanya ubushyuhe, umubare munini wa SiO2 cyangwa ikirahure cya fibre nkibikoresho byuzuye. Ku rundi ruhande, bitewe na molekile inertia yibikoresho bya PTFE, ntibyoroshye guhuza na fayili y'umuringa, bityo, igomba gukora ubuvuzi bwihariye bwo kuruhande kuruhande. Kubijyanye no kuvura hejuru, mubisanzwe ukoreshe imiti ya PTFE hejuru ya plasma cyangwa plasma yongeweho kugirango wongere uburakari cyangwa wongereho firime imwe ifata hagati ya PTFE na fayili yumuringa, ariko ibyo bishobora guhindura imikorere ya dielectric.
