Low-loss FPC

Features

□　Double-sided FPC with low transmission loss in the high frequency
      range of the GHz band.
□　Insertion loss measured: -4.7 dB @5 GHz (provided that the product
      length is 300 mm)
      Using an overlay made from liquid crystal polymer for the achievement
      of lower loss.

Basic structure


		Material	Thickness
1	Coverlay	Polyimide	12.5 μm, 25 μm
2	Adhesive layer	Epoxy	15 μm, 25 μm
3	Conductor layer	Copper foil	18 μm
4	Insulating layer	Liquid crystal polymer	100 μm

Use

□　Components that require high-speed and long-distance transmission at the rate of at least 1 Gbps
□　Components for which low loss is required by standards, such as SATA
