Cov yam ntxwv tseem ceeb ntawm high zaus PCB
Tso lus
High ceev: Hauv kev tsim cov terminals mobile, txhua millimeter ntawm qhov chaw khaws cia tuaj yeem tsim muaj txiaj ntsig zoo rau cov neeg siv khoom siv davhlau ya nyob twg. Los ntawm kev txuag chaw, koj tuaj yeem siv qhov loj dua, ntau dua qhov kev daws teeb meem, cov roj teeb loj dua, thiab cov txheej txheem nyuaj thiab cov khoom siv ntau dua.
High zaus thiab kev kub ceev: Nrog lub sijhawm tuaj txog ntawm 5G era, qhov pom tseeb hloov pauv ntawm kev ua haujlwm ntawm lub rooj tsavxwm Circuit Court yog siab zaus thiab kev kub ceev. Raws li 5G, Internet ntawm Yam thiab lwm yam kev siv yuav siv ntau zaus, nws yuav maj mam nce los ntawm yav dhau los 3GHz mus rau 6GHz lossis txawm tias 24-30GHz. Xav txog qhov siab resonance zaus ntawm 5G, nws yog ib qho tsim nyog los tswj cov impedance nruj dua. Yog tias nws tsis tsim nyob rau hauv daim ntawv siab heev, cov hlau nyias ntawm 5G PCB yuav ua rau muaj kev pheej hmoo ntawm cov teeb liab attenuation coefficient thiab txo cov ntaub ntawv ncaj ncees.
Kub kub: Muaj "impedance" thiab "dielectric poob" hauv PCB teeb liab kis. Nrog rau qhov siab zaus los yog high-ceev digitization ntawm lub teeb liab thiab qhov nce ntawm lub zog siab, PCB yuav ua kom sov mus ntxiv. Thawj theem ntawm 5G kev lag luam zaus band hauv Suav teb feem ntau qis dua 6GHz, thiab nws yuav ncav cuag 24-30ghz tom qab. Nrog rau kev txhim kho txuas ntxiv ntawm 5G kis tus nqi, tus nqi ntawm cov ntaub ntawv xa mus yuav tau nce ntau. Tsis tas li ntawd, qhov tshwm sim ntawm 3D video, huab ua si, wireless charging thiab lwm yam kev siv yuav ua rau muaj kev nce ntxiv hauv cov cua sov ntawm 5G kev sib txuas lus terminals piv nrog 4G era.
