Introduction of High Freq PCB

Brief Introduction of HF board:

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.

Materials used for HF board:

Understanding the many different properties of circuit materials can have a major impact on circuit fabrication costs, assembly concerns, reliability issues and end-use performance.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.
PCB materials are also selected by two key factors: how well they meet the needs of an end-use application and what kind of effort is required to fabricate a desired circuit with a particular material.

Design of HF board:

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.A calculation model is selected depending on the layer stackup, the circuit board layout, and the impedances requested by the customer.
