RF luam tawm Circuit Board

RF printed circuit board yog ib hom ntawv luam tawm Circuit Board siv los tsim thiab tsim cov khoom siv sib txuas lus wireless, uas tuaj yeem xa tawm thiab ua cov teeb liab ntau zaus kom ua tiav cov txiaj ntsig zoo. Cov txheej txheem tshwj xeeb thiab cov khoom siv yog siv hauv RF luam tawm Circuit Board, xws li cov khoom siv hluav taws xob ntau zaus, kev teeb tsa tshwj xeeb hauv Circuit Court, thiab cov txheej txheem tsim khoom siab.

RF printed circuit boards yog dav siv nyob rau hauv ntau yam kev sib txuas lus wireless thiab tshuab, nrog rau cov xov tooj ntawm tes, satellite kev sib txuas lus, radars, satellite navigation, thiab lwm yam.

Zoo li ntau RF Cheebtsam, PCB cov ntaub ntawv raug cais thiab muab piv los ntawm ntau qhov tseem ceeb, suav nrog tus txheeb ze dielectric tas li (Dk lossisεr), dissipation factor (Df), coefficient ntawm thermal expansion (CTE), thermal coefficient tas li ntawm Dielectric (TCDk) thiab thermal conductivity . Thaum faib cov khoom sib txawv PCB, ntau tus tsim hluav taws xob pib nrog Dk. Tus nqi Dk ntawm cov khoom siv PCB yog hais txog qhov muaj peev xwm lossis lub zog muaj nyob nruab nrab ntawm ib khub ntawm cov khoom siv ze heev uas tsim los ntawm cov khoom siv piv rau tib khub ntawm cov khoom siv hauv lub tshuab nqus tsev.

Cov yam ntxwv loj tshaj plaws ntawm RF circuit boards yog lawv cov kev ua haujlwm siab. Vim muaj cov kev txawj tshwj xeeb thiab cov ntaub ntawv uas yuav tsum tau rau kev sib kis ntawm high-frequency signals, cov ntaub ntawv thiab cov txheej txheem ntawm RF luam Circuit Court boards yuav tsum tau raws li high precision thiab siab.

Tus nqi Dk ntawm cov khoom siv PCB tuaj yeem cuam tshuam qhov loj me, wavelength, thiab cov yam ntxwv impedance ntawm cov kab sib txuas uas tsim los ntawm cov khoom ntawd. Piv txwv li, rau cov yam ntxwv impedance thiab wavelength, qhov loj ntawm cov kab sib kis tau tsim los ntawm PCB cov ntaub ntawv uas muaj qhov siab Dk yuav tsawg dua li cov kab sib txuas uas tsim los ntawm cov khoom siv PCB nrog cov nqi qis Dk, txawm hais tias lwm yam khoom siv yuav txawv. Cov neeg tsim qauv ntawm circuits nrog poob raws li qhov tseem ceeb ntawm kev ua tau zoo feem ntau yuav siv cov khoom siv PCB nrog cov nqi qis Dk, vim cov ntaub ntawv no tau poob qis dua li cov ntaub ntawv uas muaj Dk ntau dua.

Qhov tseeb, cov ntaub ntawv PCB tuaj yeem poob lub zog hluav taws xob los ntawm plaub txoj hauv kev: dielectric poob, tus neeg xyuas pib poob, xau poob, thiab hluav taws xob poob, txawm tias xaiv cov khoom siv PCB tuaj yeem tswj tau zoo dua dielectric poob thiab cov neeg xyuas pib poob. Piv txwv li, Df parameter muab ib txoj hauv kev los sib piv cov dielectric poob ntawm cov khoom sib txawv, qhov twg cov nqi qis dua Df sawv cev rau cov khoom uas muaj dielectric poob.

Rau ib qho kev sib kis kab impedance (xws li 50Ω), cov kab sib kis ntawm cov khoom siv qis Dk yuav yog lub cev dav dua li cov kab sib kis ntawm cov khoom siv Dk siab, thiab tus neeg xyuas pib poob ntawm txoj kab dav dav yuav me dua. Piv rau cov kab sib kis ntawm cov ntaub ntawv Dk siab dua, cov kab sib kis dav dav no tuaj yeem hloov mus rau kev tsim khoom ntau dua (thiab txuag cov nqi tsim khoom). Txawm li cas los xij, kev lag luam tawm yog tias lawv nyob hauv thaj chaw loj dua ntawm PCB, uas tej zaum yuav muaj teeb meem rau cov qauv tsim uas tseem ceeb heev rau kev ua haujlwm me me. Lub thickness ntawm PCB substrate, tshwj xeeb tshaj yog nws cov tooj liab conductor txheej, kuj cuam tshuam rau impedance ntawm kis kab mob. Thinner dielectric cov ntaub ntawv thiab conductors tsim nqaim dav dav kom tswj tau tus yam ntxwv impedance.

Tus neeg xyuas pib ntawm cov khoom siv PCB feem ntau teev los ntawm qhov hnyav ntawm tooj liab, xws li 1 ooj. (35 microns tuab) tooj liab lossis 2 ooj. (Thickness yog 70 um) tooj liab. Qhov zoo ntawm cov tooj liab conductors no kuj cuam tshuam rau cov neeg xyuas pib poob. Copper conductors nrog rau qhov chaw ntxhib yuav pom cov neeg xyuas pib poob ntau dua li cov neeg xyuas pib tooj liab nrog cov npoo du.

Lub rooj tsav xwm RF luam tawm no yog lub rooj tsav xwm hauv Circuit Court siv hauv 5G cov khoom, thiab Sihui Fuji tau ua tiav kev sim ua nws. Yog tias koj muaj kev thov rau cov ntawv luam tawm Circuit Board, thov hu rau peb.
