High Frequency PCB yog dab tsi? Yuav ua li cas txog daim ntawv thov ntawm high zaus PCB?Cia peb tham txog qhov no ua ke.
High Frequency PCB yog ib lub rooj tsav xwm tshwj xeeb uas muaj hluav taws xob ntau zaus. Qhov zaus ntawm cov zaus siab tshaj 1GHz. High Frequency PCB muaj cov kev xav tau siab heev rau cov khoom siv lub cev, qhov tseeb thiab qhov tsis zoo. Nws yog feem ntau siv hauv Radar, Cov Khoom Siv Tub Rog, Aerospace thiab lwm yam haujlwm.

Ua ntej, High-Frequency PCB cov ntaub ntawv? Kev ua tau zoo ntawm High-Frequency PCB nyob rau hauv wireless lossis lwm zaus zaus nyob ntawm cov khoom siv hauv tsev. Rau ntau daim ntawv thov, kev siv cov khoom siv FR4 tuaj yeem txhim kho cov khoom dielectric. Thaum tsim high-frequency PCB, feem ntau siv raw cov ntaub ntawv xws li Rogers, Isola, Taconic, Panasonic, Taiyao thiab lwm yam boards.

DK ntawm High-Frequency PCB yuav tsum yog me me thiab ruaj khov. Feem ntau, qhov me dua qhov zoo. High-Frequency PCB yuav ua rau lub teeb liab kis tau tus mob qeeb. DF yuav tsum yog me me, uas feem ntau cuam tshuam rau lub teeb liab kis tau tus mob. DF me me tuaj yeem txo cov teeb liab poob. Hauv qhov chaw ntub dej, nws muaj qhov nqus dej tsawg thiab muaj zog nqus dej, uas muaj kev cuam tshuam rau DK thiab DF.

Lub thermal expansion coefficient ntawm High-Frequency PCB yuav tsum zoo ib yam li ntawm cov ntawv ci tooj liab kom ntau li ntau tau, vim tias High-Frequency PCB tuaj yeem ua rau kev sib cais ntawm cov ntawv ci tooj liab nyob rau hauv cov ntaub ntawv ntawm alternating txias thiab kub, thiab ua tib yam li cov ntawv ci tooj liab kom ntau li ntau tau, thiaj li ua kom muaj kev ua tau zoo ntawm High-Frequency PCB. High zaus PCB muaj cov yam ntxwv ntawm tshav kub tsis kam, tshuaj corrosion kuj, cuam tshuam tsis kam thiab zoo tev tawm.
High Frequency PCB feem ntau yog siv nyob rau hauv radar system, satellite, kav hlau txais xov, cellular telecommunication system – lub hwj chim amplifier thiab kav hlau txais xov, nyob broadcast satellite, E-band point-to-point microwave txuas, xov tooj cua zaus identification (RFID) tag, airborne thiab av radar system, millimeter yoj daim ntawv thov, missile kev taw qhia system, chaw satellite transceiver thiab lwm yam kev lag luam.

Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, kev ua haujlwm ntawm cov khoom siv tau dhau los ua ntau thiab nyuaj. Ntau yam khoom siv tau tsim nyob rau hauv lub microwave zaus band lossis ntau tshaj millimeter yoj. Qhov no kuj txhais tau hais tias qhov zaus tau nce zuj zus, thiab cov kev xav tau ntawm Circuit Court board substrate tau dhau los ua ntau dua. Nrog rau qhov nce ntawm lub zog teeb liab zaus, qhov poob ntawm cov khoom siv matrix yog qhov me me, yog li qhov tseem ceeb ntawm lub rooj tsavxwm high-frequency yog qhov tseem ceeb.
