Niaj hnub no tus tib neeg tau nkag mus rau ib lub koom txoos muaj kev tshaj lij, thiab IT kev lag luam tau los ua ib lub zog muaj zog rau kev sib raug zoo. 5G era, kev tsav tsheb tsis zoo, kev sib tsoo tsheb, kev sib tsoo loj, muaj zog, qhov teeb meem, qhov Internet thiab lwm yam kev siv yuav tsum tau siv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob . Cov kev ua haujlwm ntawm lub teeb liab, kev loj hlob ntawm high-frequency tooj liab clad laminates tau los ua ib lub npe ntawm kev txhawj xeeb zoo rau PCB tuam ntxhab thiab CCL cov khw muag khoom thoob ntiaj teb. High-frequency cov ntaub ntawv uas muaj los ntawm PTFE muaj dielectric tsis tu ncua thiab dielectric poob, thiab zoo heev kub kuj tau dav siv hauv lub siab zaus teb.
High-frequency copper clad laminate processing siv cov PTFE ua ib qho substrate yuav tsum tau kub siab ntawm 380 ° C los yog siab dua rau cov ntawv xovxwm. Qhov no txo nws hwj ntau dua rau cov xovxwm thiab laminated hlau los xij.
Tam sim no, qhov kub siab tshaj plaws ntawm ntau hom ntawm cov laug cam khoo uas feem ntau siv nyob rau hauv qhov qub FR4 xovxwm yog kwv yees li 280 ° CCA PICARD's RHCS50 pawg tsav yog tam sim no lub siab tshaj plaws qhov kub siab muaj peev xwm ncav cuag 400 ° C. Cov khoom siv tau dav siv los ntawm cov khoom siv khoom hauv tsev ntau nyob hauv tsev thiab txawv teb chaws.
