Dielektrik doimiysi nima

FPC materiallari ikki turga bo'linganligi sababli, poliimid (Polimid) va polyester (Polyester), biz ularni bu erda ajratishimiz kerak.

1. Polimid

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. Polyester

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.

Biroq, ishlab chiqarish jarayonida uning o'lchov barqarorligi Polimidnikidan biroz yomonroq. Bundan tashqari, u zaif yirtiqqa chidamliligiga ega va payvandlash haroratiga nisbatan sezgir. Uning dielektrik o'tkazuvchanligi 3,4 ga teng.

Yuqoridagi fpc moslashuvchan taxtasining dielektrik o'tkazuvchanligi muharrir tomonidan tuzilgan, bu sizga foydali bo'ladi deb umid qilaman
