I have designed 300+ PCB files including 8 layers design on Altium designer. As an electrical engineer, I am very familiar with circuit design, PCB design, LVDS(Low Voltage Differential Signaling), High-speed integration, EMI/EMC compliance, PCB antenna design. This PCB is an 8 layers PCB related to high-speed signal tuning and the BGA footprint trace. I design the circuit on Altium, Eagle, and KiCAD.
