- MCL-FX-35 has low water absorption property, which is suitable for high frequency double-sided PWBs.
Features
- Superior dielectric properties effective in decreasing the signal attenuation in GHz bands.
- Very low water absorptivity, and hygroscopic dielectric drift property is stable.
- High Tg, and well-suited for lead-free soldering process.
