In high-speed digital design, signal integrity problems often hide in the least obvious places—vias. As signal rates move from 10Gbps to 25Gbps, 56Gbps, and even 112Gbps, an ordinary through-hole via

If you've done high-speed PCB design, you've heard the term "impedance control." But do you really understand the full chain of impedance control? Many engineers assume that impedance control is simpl

If you've been following PCB industry news lately, you've probably noticed the wave of price increases. As of September 2026, major copper-clad laminate (CCL) manufacturers including Kingboard Laminat
