Mis on dielektriline konstant

Kuna fpc materjalid jagunevad kahte tüüpi, polüimiid (polüimiid) ja polüester (polüester), peame need siin eraldama.

1. Polüimiid

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. Polüester

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.

Selle mõõtmete stabiilsus tootmisprotsessi ajal on aga pisut halvem kui polüimiidil. Lisaks on sellel halb rebenemiskindlus ja see on tundlikum keevitustemperatuuri suhtes. Selle dielektriline konstant on 3,4.
