Dab tsi yog qhov siab zaus PCB board

High-frequency PCB yog ib lub rooj tsav xwm tshwj xeeb uas muaj hluav taws xob ntau zaus, thiab cov zaus zaus siab tshaj 1GHz. High-frequency PCBs muaj qhov yuav tsum tau ua ntawm lub cev muaj zog, precision, thiab kev tsis zoo, thiab feem ntau siv hauv radar, cov cuab yeej siv tub rog, aerospace thiab lwm yam haujlwm.

Ua ntej tshaj plaws, cia peb saib seb cov ntaub ntawv twg yog siv los ua cov PCBs ntau zaus? Kev ua tau zoo ntawm cov laug cam loj hauv wireless lossis lwm yam kev siv high-frequency nyob ntawm cov khoom siv hauv tsev. Rau ntau daim ntawv thov, dielectric zog tuaj yeem txhim kho los ntawm kev siv cov ntaub ntawv laminated FR4. Thaum tsim high-frequency PCBs, feem ntau siv boards muaj xws li Rogers, ISOLA, Taconic, Panasonic, Taiyao thiab lwm yam boards.

Lub DK ntawm high-frequency PCB yuav tsum yog me me thiab ruaj khov, feem ntau qhov me dua qhov zoo dua, high-frequency PCB yuav ua rau cov teeb liab kis tau tus mob qeeb. DF yuav tsum me me, uas feem ntau cuam tshuam rau lub teeb liab kis tau tus mob zoo. Ib qho me me DF tuaj yeem txo cov teeb liab poob raws li, thiab nyob rau hauv qhov chaw ntub dej, qhov nqus dej tsawg thiab cov dej nqus dej muaj zog, uas muaj kev cuam tshuam rau DK thiab DF.

Lub thermal expansion coefficient ntawm high-frequency Circuit Court board yuav tsum zoo ib yam li tooj liab ntawv nyiaj ntau npaum li sai tau, vim hais tias lub high-frequency Circuit Court board yuav ua rau cov ntawv ci tooj liab sib cais nyob rau hauv lub alternating txias thiab kub, thiab nws. yuav tsum yog tib yam li cov ntawv ci tooj liab ntau npaum li qhov ua tau kom ntseeg tau tias lub rooj tsav xwm muaj ntau zaus. Kev ua tau zoo tuaj yeem ua si zoo kawg nkaus. High-frequency PCB 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, antennas, cellular telecommunications systems - lub hwj chim amplifiers thiab antennas, ncaj qha xov tooj cua 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 kev taw qhia system, chaw satellite transceiver thiab lwm yam teb.

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 ntau dua, thiab ntau yam khoom siv tau tsim nyob rau hauv microwave zaus band lossis ntau tshaj qhov millimeter yoj. Qhov no kuj txhais tau hais tias qhov zaus txuas ntxiv mus ntxiv, thiab cov kev xav tau ntawm lub substrate ntawm lub rooj tsavxwm Circuit Court kuj tau nce siab dua. Raws li qhov zaus ntawm lub zog hluav taws xob teeb liab nce, qhov poob ntawm cov khoom siv hauv paus yuav tsum muaj tsawg heev, yog li qhov tseem ceeb ntawm cov boards high-frequency yog qhov tseem ceeb.
