With the rapid development of high-speed interconnects, 5G communication, AI servers, and optical modules, PCB design is no longer simply a matter of “choosing the best material if the budget allow...
With the rapid development of 5G, AI servers, optical modules, and data center switches, PCB material performance—particularly in terms of loss, stability, and manufacturability—has be...
In high-speed and high-frequency PCB design, many engineers focus on trace width, impedance, and differential spacing, yet overlook a more critical factor — the continuity of the retur...
In HDI PCB prototyping and mass production, more than 70% of rework, delays, and additional costs come from insufficient consideration of manufacturing capabilities during the design stage. B...
1. Ignoring the Actual Copper Thickness (Including Plating Growth)
The finished copper thickness is often much higher than the nominal value, and outer-layer plating has a major ...
