X'inhu l-Kostanti Dielettrika

Peress li l-materjali fpc huma maqsuma f'żewġ tipi, polyimide (Polyimide) u poliester (Polyester), irridu nisseparawhom hawn.

1. Polyimide

Polyimide (PI for short) is the most commonly used thermally cured insulating material in flexible circuit processing. Material thicknesses typically range from 12.5 μm (0.5 mil) to 125 μm (5 mil). Divided into glued and glueless, the dielectric constant of glued is 3.5, and the dielectric constant of no glue is 3.3.

2. Poliester

Polyester is made of polyethylene terephthalate (PET for short, polyethylene terephthalate). The thickness range of its application to flexible boards is generally 25μm (1mil) 125μm (5mil). It has the same excellent softness and electrical properties as Polyimide.

Madankollu, l-istabbiltà dimensjonali tagħha matul il-proċess tal-manifattura hija kemxejn agħar minn dik tal-Polyimide. Barra minn hekk, għandu reżistenza fqira tad-dmugħ u huwa aktar sensittiv għat-temperatura tal-iwweldjar. Il-kostanti dielettrika tagħha hija 3.4.

Dan ta 'hawn fuq huwa l-kostanti dielettrika tal-bord flessibbli fpc miġbura mill-editur, nispera li jkun ta' għajnuna għalik
