ABOUT HIGH FREQUENCY PCB?
You’re dealing with wireless networks or applications that include particular signal transmission amid objects? Consider getting a high-frequency PCB.
These PCBs come in a wide range of frequencies, starting at 500MHz and going all the way up to 2GHz. If you need high-speed design applications, they are perfect for that use case! You can also find them on microwaves or cellular devices if you’re looking for something more specific like that as well.
This type of PCB has a lot more signal sensitivity than most. That’s why it needs high-frequency laminates to help sustain the thermal heat transfer for your application.
The type of high-frequency board you choose will determine the overall performance, which can be affected to a degree by any change in the material’s dielectric constant.
The materials used for your signal boards are important because they’ll affect its impedance and how well it performs.
KEY FEATURES OF HIGH
FREQUENCY PCB
Small and stable. Besides, no delay in signal transmission.
Ideal for signal transmission. And reduce signal wastage effectively.
No copper foil separation with temperature changes.
HF boards with low water absorptivity.
Impressive properties like impact endurance, heat resistance, peel-off resistance, and chemical resistance. Plus, High peel-off resistance improves the PCB's signal quality.
Adequate spacing for boards. And It also has smaller diameter vias and invariably low conductance.
THE REQUIRED MATERIALS FOR HIGH FREQUENCY CIRCUIT BOARD
A higher frequency metal’s circuit boards are more demanding on the materials, and so one of its best features is a better permittivity.
We also have other needs similar to construction with reduced tolerance in DK and insulation thickness. It also includes a reduced attenuation for competent signal transmission.
We know how to pick out the perfect padding for all of our projects and use FR4, a material that is strong enough for most requirements. We also make sure to control high-frequency materials with enhanced dielectric properties.
And so it might be worth considering this new development in technology. This material is just what you need for your next project because, as I mentioned earlier, it has a low DK and loss factor, which will save on energy costs while also being durable enough to withstand high temperatures without melting or cracking!
Some of the materials we use are Taconic TLX, Rogers, ISOLA IS620 E-fiber glass, etc.
Here’s a table that explains each of the material’s properties:
| Materials for HF circuit boards | Tg (℃) | CTE-z (PPM/℃) | Peel Strength(N/mm) | Td Value (℃) | DK Loss Tangent | Thermal Conductivity (W/m*K) | Surface Resistivity(MΩ) | Electric Strength (KV/mm) | Ԑr (@10GHz |
