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 of the materials used. 
 
Multi-CB provides you with know-how, all popular materials and qualified manufacturing processes - reliably even for complex requirements.

Design of HF circuit boards 
Multi CB supports you starting immediately in the design phase. We help you to find appropriate substrates, dimensioning the conductor width and spacing, as well as with calculating the impedances. 
 
Our offer for HF circuit boards: 
 
HF-material (low-loss), e.g. PTFE substrate 
Impedance controlled multilayers 
Sandwich buildup for material combinations 
Microvias strating from 75µm 
Controlled production line / with comprehensive test certificate, as needed 
Backdrill 
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. pcbassemblycn.com
