High Frequency&High Speed PCB/



rogers-4360g2-pcb, We have made the Rogers core and FR4 core PCB with a hybrid structure. this is a 6 layer Rogers board. there are many Rogers base materials in our company.

High Frequency Laminates

We buy these materials from an agent at Rogers Materials and then process and produce blank circuit boards. We don’t produce core materials. The following information is for reference only.


RO4360G2™ laminates are 6.15 Dk, low loss, glass-reinforced, hydrocarbon ceramic-fifi lled thermoset materials that provide the ideal balance of performance and processing ease. RO4360G2 laminates extend Rogers’ portfolio of high performance materials by providing customers with a product that is lead-free process capable and offers better rigidity for improved processability in multi-layer board constructions, while reducing material and fabrication costs.

RO4360G2 laminates process similar to FR-4 and are automated assembly compatible. They have a low Z-axis CTE for design flfl exibility and have the same high Tg as all of the RO4000 product line. RO4360G2 laminates can be paired with RO4400™ prepreg and lower-Dk RO4000 laminate in multi-layer designs.

RO4360G2 laminates, with a Dk of 6.15 (Design Dk 6.4), allow designers to reduce circuit dimensions in applications where size and cost are critical. They are the best value choice for engineers working on designs including power amplififi ers, patch antennas, ground-based radar, and other general RF applications.

High frequency circuit boards

High frequency PCB with Rogers material The increasing complexity of electronic components and switches continually requires faster signal flow rates, and thus higher transmission frequencies. Because of short pulse rise times in electronic components, it has also become necessary for high frequency (HF) technology to view conductor widths as an electronic component. Depending on various parameters, HF signals are reflected on circuit board, meaning that the impedance (dynamic resistance) varies with respect to the sending component. To prevent such capacitive effects, all parameters must be exactly specified, and implemented with the highest level of process control. Critical for the impedances in high frequency circuit boards are principally the conductor trace geometry, the layer buildup, and the dielectric constant (εr) of the materials used.

ALCANTA PCB provides you with know-how, all popular materials and qualified manufacturing processes – reliably even for complex requirements.


Materials used for HF circuit boards:

High-frequency boards, e.g. for wireless applications and data rates in the upper GHz range have special demands on the material used: Adapted permittivity Low attenuation for efficient signal transmission Homogeneous construction with low tolerances in insulation thickness and dielectric constant For many applications, it is sufficient to use FR4 material with an appropriate layer buildup. In addition, we process high-frequency materials with improved dielectric properties. These have a very low loss factor, a low dielectric constant, and are primarily temperature and frequency independent. Additional favourable properties are high glass transition temperature, an excellent thermal durability, and very low hydrophilic rate. We use (among others) Rogers or PTFE materials (for example, Teflon from DuPont) for impedance controlled high frequency circuit boards. Sandwich buildups for material combinations are also possible.


Impedance CheckThe impedance defined by the customer is tested by our CAM station engineers on manufacturability. Depending on the layer buildup, the PCB layout and the customer’s requested impedances a calculation model is chosen. The result is any required modification of the layer builduo and the necessary adjustments to the relevant conductor geometries. After the manufacture of high frequency circuit boards, the impedances are checked (with a precision of up to 5%), and the detailed results are recorded exactly in a test protocol.
