What Is PCB Prepreg?
PCB prepreg’s Tg, Dk, and CTE impact thermal stability, signal integrity, and reliability. Wrong choice causes delamination, impedance mismatch, failures.
What Are PCB Step Holes and Slots?
Step holes revolutionize 5G PCBs: laser-drilled microvias enhance GHz signal integrity, thermal paths, and multilayer density in high-frequency circuits.
