CHEMIFLEX L

[Newly Developed]

Flexible Copper Clad Laminate for High Frequency Applications

 

Characteristics

CHEMIFLEX L is a FCCL, Flexible Copper Clad Laminate, which is composed, in no use of adhesives, of LCP, liquid crystal polymer, film of 50 micron as insulator and rolled copper foil of 18 micron of which surfaces are as rolled and not roughed.

● Excellent high frequency characteristic

● No performance change after moisture adsorption

● Excellent dimension stabilities

● Satisfactory peel strength

● Excellent bending resistance
