Telecom PCB FAQ
Common questions about high-frequency manufacturing, signal integrity, and material strategies.
How do you manage heat in high-power 5G base station PCBs?
We utilize heavy copper layers (up to 4oz), integrated copper coins, and thermally conductive laminates. We also optimize stack-ups for efficient heat dissipation to the external chassis, ensuring components remain within safe operating temperatures in uncooled outdoor environments.
What is PIM and why is it important for communication PCBs?
Passive Intermodulation (PIM) occurs when non-linearities in the PCB generate interference. In high-power telecom systems, low PIM is critical for maintaining network capacity. We achieve low PIM through specialized copper foil treatments, solder mask selection, and IPC Class 3 manufacturing cleanliness.
Do you support back-drilling for networking line cards?
Yes. We provide precision back-drilling with depth control of ±0.1mm. This processes removes the unused portions of via stubs, which is essential to prevent reflections and resonance in networking hardware operating at 25Gbps per lane and above.
Which materials do you recommend for 800G networking designs?
For 800G (112G per lane) throughput, we typically recommend ultra-low loss materials such as Panasonic Megtron 7/8, Isola Tachyon 100G, or Park Meteorwave 8000. These offer exceptionally low dissipation factors (Df) and stable dielectric constants (Dk) across wide frequency ranges.
