Rogers thiab F4B muaj qhov sib txawv tseem ceeb hauv cov khoom muaj pes tsawg leeg, kev ua tau zoo, tus nqi, daim ntawv thov scenarios, thiab kev ua tau zoo tag nrho, raws li hauv qab no:
1. Cov khoom muaj pes tsawg leeg thiab cov yam ntxwv yooj yim
Rogers cov khoom siv:
Siv cov ceramic ntim cov hydrocarbons lossis hloov kho epoxy resin raws li cov tub ntxhais, qhov poob qis tuaj yeem ua tiav los ntawm cov qauv kev ua kom zoo (xws li Df ntawm RO4350B) 0.0037@10GHz ) Thiab qhov ruaj khov dielectric tsis tu ncua (Dk ≈ 3.48 ± 0.03). Nws cov coefficient ntawm thermal expansion (CTE) yog ze rau ntawm cov khoom siv tooj liab, thiab nws cov Z-axis expansion coefficient yog qis dua FR-4 (46ppm / degree), kom ntseeg tau qhov ruaj khov ntawm qhov kub thiab txias.
F4B (PTFE raws):
Siv polytetrafluoroethylene (PTFE) ua cov khoom tseem ceeb, Df yog qhov tsawg heev (xws li 0.0009@10GHz) Dk yog kwv yees li 2.2 ± 0.05 thiab hloov me ntsis nrog zaus. PTFE muaj qhov kub thiab txias tsis kam (Tg yam tsis muaj qhov taw tes tsis zoo, kev siv tsis tu ncua tsawg dua lossis sib npaug li 260 degree), muaj zog tshuaj lom neeg ruaj khov, tab sis tsis tshua muaj zog (khoov lub zog tsawg dua lossis sib npaug rau 100MPa).
2. Kev ua tau zoo thiab kev ua haujlwm nyuaj
Rogers cov khoom siv:
Tau tshaj cov txheej txheem FR-4 ib txwm muaj xws li tooj liab deposition thiab etching, tsis muaj cov cuab yeej tshwj xeeb yuav tsum tau, siab ua tiav, thiab siab yield. Piv txwv li, RO4000 series tuaj yeem siv ncaj qha rau FR-4 cov kab ntau lawm, txo cov nqi tsim khoom los ntawm 30%.
F4B (PTFE raws):
Cov txheej txheem kev kho sodium tshwj xeeb yog xav tau, thiab lub siab thiab kub yuav tsum tau tswj nruj me ntsis thaum lamination kom tsis txhob muaj npuas thiab delamination. Drilling yuav tsum tau siv cov cuab yeej tshwj xeeb, uas nyuaj rau kev ua haujlwm thiab raug nqi.
3. Tus nqi thiab tus nqi -kev ua tau zoo
Rogers cov khoom siv:
Tus nqi tsev yog 30 npaug siab dua li ntawm FR-4, tab sis qis dua PTFE substrate. Nws tus nqi kom zoo dua yog nyob rau hauv cov txheej txheem compatibility thiab loj -scale ntau lawm, haum rau scenarios nrog rau kev ua tau zoo tab sis siv nyiaj tsawg (xws li automotive radar, industrial high-frequency khoom).
F4B (PTFE raws):
Tus nqi sib txawv nyob ntawm tus qauv, thiab tsuas yog haum rau siab -kawg tshwj xeeb teb xws li millimeter yoj radar thiab kev sib txuas lus hauv aerospace. Piv txwv li, lub teeb liab txheej ntawm 60GHz microwave relay chaw nres tsheb siv PTFE cov khoom, uas attenuates tsuas yog 0.8dB ib 'meter'.
4. Daim ntawv thov scenarios thiab kev ua tau zoo adaptation
Rogers cov khoom siv:
RO4000 series: tsim tshwj xeeb rau millimeter yoj zaus bands, haum rau siab - zaus xwm txheej xws li 5G hauv paus chaw nres tsheb, tsheb radar (77GHz), satellite kev sib txuas lus, thiab lwm yam.
RO3000 series: Tus nqi optimized, haum rau kev lag luam daim ntaub ntawv xws li muaj sensors thiab cov khoom siv kho mob.
RT/duroid series: Tsim los rau cov khoom siv hluav taws xob nruj, haum rau cov xwm txheej siab zog xws li lub zog amplifiers thiab kav hlau txais xov.
F4B (PTFE raws):
Ultra high zaus scenario: Txhawb ntau zaus bands saum 40GHz (xws li 94GHz aerospace radar), uas tsis tshua muaj poob, haum rau kev siv hla band (xws li 6G terahertz kev sib txuas lus).
Ib puag ncig hnyav: tiv taus cov kua qaub muaj zog, alkalis, thiab cov kuab tshuaj organic, haum rau cov tshuaj tiv thaiv corrosion xws li cov cuab yeej siv tshuaj lom neeg thiab cov duab kho mob.
Ua ntej Rogers: Yog tias koj xav tau qhov sib npaug ntawm kev ua tau zoo thiab tus nqi, thiab daim ntawv thov scenario qis dua 30GHz (xws li automotive radar, industrial high- khoom siv zaus).
Ua ntej F4B: Yog tias nrhiav qhov kawg siab tshaj - kev ua haujlwm zaus (xws li millimeter yoj radar, 6G terahertz kev sib txuas lus) lossis hloov tau rau qhov chaw hnyav (xws li tshuaj lom neeg thiab kev kho mob corrosion).
Mixed compression tsim: Thaum tus nqi rhiab tab sis xav tau hauv zos siab -frequency kev ua tau zoo, Rogers + FR-4 mix compression scheme (xws li nto Rogers + puab FR-4) tuaj yeem siv los txo qhov poob los ntawm 15% -25%.
