Hello Everyone,
Today, we're going to talk about TLX high frequency PCB.
TLX is a series of PTFE fiberglass laminates launched by Taconic
Company. It offers reliability in a wide range of RF applications.
This material is versatile due to its 2.45 - 2.65 DK range. It is
suitable for low layer count microwave PCBs.
Let's firstly see the advantages that we benefit from.
1. Dimensionally stable:
It can experience high level of vibration, such as space launch.
2. Excellent thermal properties:
It can experience high temperature exposure, such as working in
engine modules.
3. Low and stable dielectric constant and tightly controlled DK.
Ranging 2.45 to 2.65 at tolerance +/-0.04
4. Low moisture absorption
Undergoing extreme severe environments, such as working at sea
5. Flame retardant grade, UL 94 VO
6. Low DF
TLX is ideal material for use in the application of following list
due to its wide DK range and available thickness and copper
cladding.
1. Radar systems,
2. Mobile communications,
3. Microwave test equipment,
4. Microwave transmission devices,
5. Antennas,
6. Mixers, splitters, filters and combiners
There’re TLX-0, TLX-9, TLX-8, TLX-7 and TLX-6 in TLX family. Often
it’s used in single layer board, double layer board etc. Surface
finish is mainly with bare copper, hot air level and immersion
gold.
