High Frequency PCB

What is High Frequency PCB

Introduction:

1. High Frequency PCB or calls Microwave PCB / Radio Frequency PCB/RF PCB are widely used in wireless communications,wireless networks and satellite communications, in particular the popularity of 3G networks exacerbate the market demand for the product on the High Frequency PCB.Today, the demand for Microwave material PCB design is on the rise, Access to wireless high speed (high frequency) data is quickly becoming a necessity in multiple markets like Defense、Aerospace and Mobile Networks. Evolving market needs continue to drive forward development of High Frequency printed circuit board. like 50+ GHz microwave radios or defense airborne systems, also it can meet Halogen Free PCB together.

2. RF PCB & High-Frequency PCB made from polytetrafluoroethylene(PTFE PCB),ceramic filled fluoropolymer, or ceramic filled hydrocarbon thermosets materials with improved dielectric properties. this material have a low dielectric constant of 2.0-3.8, a low loss factor and excellent low loss characteristics, also with favourable properties are high glass transition temperature, a very low hydrophilic rate,an excellent thermal durability.The expansion coefficient of PTFE PCB material is similar to the copper which allows the material to exhibit excellent dimensional stability.

3.Panda PCB company has increased the investment of production equipment and research & development on High Frequency PCB field over the last few years,It is to meet to market development of the RF PCB for our customers from all around the world,We have rich experience in PTFE PCB manufacturing of various high-frequency circuit boards for quick turn prototypes and mass production.Our normal Teflon material supplier including: Rogers PCB, Nelco PCB,Taconic PCB, Arlon PCB...Detail please reference > About Us>PCB Materials.

  RF PCB Key Features:

1. Low Dielectric constant(2.40) with tight tolerance. PTFE PCB and Ceramic PCB filled composite.
2. Low Dissipation Factor tan(loss tangent),Low Df and Dk allows for low signal distortion and faster signal propogation required by high frequency and high reliability applications.
3. Lower Z-axis CTE,offering supperior PTH reliability.The low Z-CTE and CAF resistance provide long term reliability for both RF and digital applications.
4. High Tg 200 by DMA. Higher heat resistance TD>370, T300>60min. Excellent thickness control for tight tolerance impedance application.
5. Lower moisture absorption with excellent resistance against moisture and heat.
6. Lead-Free Assembly Compatible,Ideally suited for assemblies with a maximum reflow. temperature of 260 on a conditions of 5-cycle/10 second.
