Taconic TLF-35 High Frequency PCB with 30mil, 60mil Thick Coating Immersion Gold, HASL, Immersion
Silver and Tin
(PCB's are custom-made products, the picture and parameters shown
are just for reference)
Hello everyone,
Today, we talk about TLF-35 high frequency PCB.
Taconic TLF-35 is an organic-ceramic laminates which is based on
woven glass reinforcement. It is a result of both ceramic fill
technology and coated PTFE fiberglass.

We benefit from its following advantages:
1. Improved phase intermodulation distortion (PIMD) with DK3.5
TLF-35 is designed to obtain improved PIMD performances on size
effective PCBs for antenna application. The dielectric constant of
TLF-35 is 3.5 which is similar with PIMD required levels.
2. Improved PTH quality
It shows better PTH quality which results in more stable hole wall
and insulation resistance even for the smaller drilled holes.
3. Stable at high frequency
TLF-35 is designed to offer superior high frequency performance.
4. Low moisture absorption
Its ultra-low moisture absorption rate and low dissipation factor
minimize phase shift with frequency.
5. Cost.
Low cost realizes high volume commercial microwave and radio
frequency application.
Typical applications are shown as follows.
1. Antenna
2. Power amplifiers (TD-SCDMA, WCDMAS, LTE, WLAN etc.)
3. LNA, Repeater PA
4. Passive RF components (Filters, Couplers etc.)
