Koj puas muaj kev nkag siab txog dab tsi high-frequency PCB yog? Cov ntawv thov twg yog cov PCBs siab siv rau? Niaj hnub no, cia peb kawm txog dab tsi high-frequency PCBs yog thiab nyob rau hauv uas lawv tau thov.
High zaus PCB yog ib lub rooj tsav xwm tshwj xeeb uas muaj hluav taws xob ntau zaus, nrog cov zaus siab tshaj 1GHz. High zaus PCBs xav tau kev ua haujlwm siab ntawm lub cev, qhov tseeb, thiab cov kev tsis sib xws, thiab feem ntau siv hauv radar, cov cuab yeej siv tub rog, aerospace, thiab lwm yam.
Ua ntej, cia peb nkag siab tias cov ntaub ntawv twg siv los ua cov PCBs ntau zaus? Kev ua tau zoo ntawm cov laug cam nyob rau hauv wireless lossis lwm qhov chaw siab zaus nyob ntawm cov khoom siv hauv tsev. Rau ntau daim ntawv thov, siv cov ntaub ntawv FR4 txheej tuaj yeem txhim kho dielectric zog. Thaum tsim cov PCBs, feem ntau siv cov laug cam muaj xws li Rogers, ISOLA, Taconic, Panasonic, Taiyao, thiab lwm yam boards.
Lub DK ntawm high-frequency PCBs yuav tsum yog me me thiab ruaj khov, feem ntau yog qhov me dua qhov zoo dua, vim tias PCBs siab zaus tuaj yeem ua rau cov teeb liab xa mus qeeb. DF yuav tsum yog me me, uas feem ntau cuam tshuam rau qhov zoo ntawm cov 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 peev xwm nqus dej muaj zog, uas muaj kev cuam tshuam rau DK thiab DF.
Lub thermal expansion coefficient ntawm high-frequency Circuit Court boards yuav tsum nyob ze li sai tau rau cov tooj liab ntawv ci, vim hais tias high-frequency Circuit Court boards yuav ua rau tooj liab ntawv ci sib cais thaum kub thiab txias alternation. Txhawm rau kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm cov khoom siv hluav taws xob ntau zaus, nws yog ib qho tsim nyog yuav tsum nyob ze li qhov ua tau rau cov ntawv ci tooj liab. High zaus PCBs muaj cov yam ntxwv ntawm tshav kub tsis kam, tshuaj corrosion kuj, cuam tshuam tsis kam, thiab zoo tev kuj.
High zaus PCBs feem ntau yog siv nyob rau hauv radar systems, satellites, kav hlau txais xov, cellular telecommunications systems - lub hwj chim amplifiers thiab antennas, nyob broadcasts satellites, E-band point-to-point microwave links, Xov tooj cua zaus Identification (RFID) cim npe, huab cua thiab hauv av radar systems, millimeter yoj daim ntawv thov, missile guidance systems, chaw satellite transceivers, thiab lwm yam teb.
Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej technology, cov cuab yeej ua haujlwm tau dhau los ua qhov nyuaj, thiab ntau yam khoom siv tau tsim nyob rau hauv microwave zaus band lossis txawm tshaj millimeter yoj. Qhov no kuj txhais tau hais tias qhov zaus yog tas li nce, thiab cov kev xav tau ntawm lub substrate ntawm lub rooj tsavxwm Circuit Court kuj nce. Raws li qhov zaus ntawm lub zog teeb liab nce, qhov yuav tsum tau ua rau poob ntawm cov khoom siv substrate yog me me, yog li qhov tseem ceeb ntawm high-frequency boards yog qhov tseem ceeb.
