Copper clad laminate yog dab tsi?
Copper-clad laminate yog ib lub phaj zoo li cov khoom tsim los ntawm impregnating hluav taws xob fiberglass daim ntaub los yog lwm yam khoom siv ntxiv nrog resin, npog ib los yog ob sab nrog tooj liab ntawv ci thiab kub nias. Nws yog hu ua tooj liab-clad laminate. Clad Laminate (CCL), hu ua tooj liab clad laminate.
Raws li cov khoom siv substrate hauv kev tsim cov ntawv luam tawm hauv Circuit Court boards, tooj liab clad laminates feem ntau ua lub luag haujlwm ntawm kev sib txuas, rwb thaiv tsev thiab kev txhawb nqa rau cov ntawv luam tawm Circuit Board, thiab muaj kev cuam tshuam zoo rau kev sib kis ceev, lub zog poob thiab cov yam ntxwv impedance ntawm cov teeb liab hauv Circuit Court. . , Yog li ntawd, kev ua tau zoo, kev ua tau zoo, kev ua haujlwm hauv kev tsim khoom, qib kev tsim khoom, tus nqi tsim khoom, thiab kev cia siab rau lub sijhawm ntev thiab kev ruaj ntseg ntawm cov ntawv luam tawm Circuit Board feem ntau nyob ntawm cov tooj liab clad laminate.
Feem ntau hais lus, tooj liab clad laminates tuaj yeem muab faib ua ob pawg: nruj tooj liab clad laminates thiab hloov tau tooj liab clad laminates.
1.2.1 Rigid tooj liab clad laminate
1.2.1.1 Raws li cov ntaub ntawv sib txawv thiab cov qauv ntawm tooj liab-clad laminates, lawv tuaj yeem muab faib ua cov organic cob tooj liab-clad laminates, hlau-raws li (core) tooj liab-clad laminates thiab ceramic-based tooj liab clad laminates.
1.2.1.2 Raws li lub thickness ntawm tooj liab-clad laminate, nws yuav muab faib ua pa boards thiab nyias boards.
1.2.1.3 Raws li cov ntaub ntawv txhawb nqa siv hauv tooj liab clad laminates, lawv tuaj yeem muab faib ua hluav taws xob fiberglass ntaub-raws li tooj liab clad laminates, ntawv-raws li tooj liab clad laminates thiab composite-based tooj liab clad laminates.
1.2.1.4 Raws li cov insulating resin siv nyob rau hauv tooj liab-clad laminates, ib co resin hu ua ib co copper-clad laminate. Xws li epoxy cob tooj liab clad laminate, polyester cob tooj liab clad laminate, cyanate resin tooj liab clad laminate, thiab lwm yam.
Tsis tas li ntawd, muaj cov tshwj xeeb nruj tooj liab-clad laminates cais raws li cov nplaim hluav taws kub thiab qee yam khoom tshwj xeeb.
1.2.2 Flexible tooj liab clad laminate
Tam sim no, hloov tau yooj yim tooj liab-clad laminates tau muab faib ua polyester zaj duab xis hom (nplaim retardant thiab non-flame retardant), polyimide zaj duab xis hom (nplaim retardant, tsis-nplaim retardant, ob-txheej txheej thiab peb txheej txheej) thiab ultra-thin electronic iav fiber ntaub Peb hom.
