Šta je dielektrična konstanta

Pošto se fpc materijali dijele na dvije vrste, poliimid (Polyimide) i poliester (Polyester), moramo ih ovdje razdvojiti.

1. Poliimid

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.

Međutim, njegova dimenzijska stabilnost tokom procesa proizvodnje je nešto lošija od poliimida. Osim toga, ima slabu otpornost na kidanje i osjetljiviji je na temperaturu zavarivanja. Njegova dielektrična konstanta je 3,4.
