Characteristics 

Low-dielectric constant/dissipation factor

Specific permittivity (Dk) 2.8 or less

When high-frequency signals flow through the circuit, signal delay is reduced by suppressing the capture of electrons.

Dielectric loss tangent (Df) 0.0020 or less

When high-frequency signals flow through a circuit, transmission loss is reduced by suppressing the electrical energy of the signal from being converted into heat.

Excellent adhesion

Adhesive force to LCP/MPI 10N/cm or more

It has excellent adhesion to both copper foil and high-frequency substrate materials that are difficult to bond with normally.

  • LCP:Liquid Crystal Polymer MPI:Modified PI

Heat resistance

Solder heat resistance test 288℃ passed

No bubble or delamination occurs even when the material is exposed to high heat during the soldering process.

はんだ耐熱試験

Excellent drilling processability

Minimizes scraping during drilling

It is possible to minimize the amount of scraping that occurs during drilling (laser/drill, etc.) to make via holes and through holes in multilayer FPCs.
