Hello Everyone,
Today, we're talking about high frequency PCB built on TLY
material.
TLY laminates are manufactured with very lightweight woven
fiberglass, which are from Taconic Company. They are more
dimensionally stable than chopped fiber reinforced PTFE composites.
Since they are more mechanically stable, it is suitable for high
volume manufacturing.
The low dissipation factor enables successful deployment for
automotive radar applications designed at 77 GHz as well as other
antennas in millimeter wave frequencies.
We benefit from its following advantages:
1. Dimensionally stable:
High volume fabrication becomes possible.
2. Lowest DF
In the low dielectric constant range, the dissipation factor is
approximately 0.0009 at 10 GHz.
3. Low moisture absorption
It can work in severe environment.
4. High copper peel strength
It’s high up to 2.32, dimensionally stable.
5. Uniform and consistent DK
For most thicknesses, the dielectric constant can be specified
anywhere within this range with a tolerance of +/-0.02
Typical applications include:
Automotive radar
Cellular communications
Satellite communications
Power amplifiers, Filters, couplers
LNBs, LNAs, LNCs
Aerospace, avionics
Phased array antennas
There’re 6 members in TLY family. We have stock for TLY-5. Others
are purchased according to clients’ requirement.
