Frequently Asked Questions

Here are some common FAQs about RF PCB manufacturers:

Q1. What are RF PCBs and what makes them challenging to manufacture?

A1. RF printed circuit boards operate at radio frequencies – from under 3 GHz for 4G LTE to over 90 GHz for latest 5G networks. High-frequency signals demand precise dielectric properties, superior signal integrity at multiple lamination interfaces, smooth impedance matching and effective EMI shielding – making them harder to fabricate than typical digital PCBs.

Q2. Why is HDI technology important for advanced RF PCBs?

A2. High Density Interconnect (HDI) allows packing more components and circuitry by adopting thinner dielectric buildup layers (below 60 μm) interconnected by smaller micro-vias (50 to 150 μm diameter), enabling denser RF solutions.

Q3. Are ceramics or laminates better substrates for mmWave RF PCBs?

A3. Both material types have tradeoffs – ceramic substrates generally provide better thermal performance crucial for power amplifiers in mmWave modules but laminates offer greater design flexibility and lower cost. Hybrid RF boards using ceramic tiles embossed on laminate cores are an emerging option.

Q4. What are some emerging technologies used in automotive RF PCBs?

A4. Stringent reliability and environmental resistance requirements for vehicle-use makes adopting RF/microwave materials like liquid crystal polymers along with new interface treatments like plasma activation highly useful to realize robust, long-lasting RF PCB performance.

Q5. What role does modeling and simulation play during RF PCB design?

A5. Platforms like Ansys HFSS, Keysight ADS, Cadence Sigrity, Mentor HyperLynx offer accurate full-wave electromagnetic, thermal, signal integrity and power integrity simulations of complex RF PCBs – minimizing discrepancy between virtual prototyping designs and hardware testing.
