In high-speed design, the stackup = the foundation of signal quality. More than 80% of issues such as impedance fluctuation, crosstalk, EMI, and improper return paths come from stackup mistak...

In multilayer PCB projects, stackup design is often more critical than routing itself. Many problems related to high-speed performance, EMC, and product reliability ultimately trace back to an impr...
