Rigid PCB Durable Circuitry for Fixed Applications

Rigid PCBs (Rigid Printed Circuit Boards) are circuit boards with a rigid, inflexible substrate—typically made of FR-4 (fiberglass-reinforced epoxy resin), ceramic, or metal-core materials—designed to maintain their shape in fixed electronic assemblies. Unlike flexible PCBs (which bend to fit tight

What are the high-frequency and high-speed PCB materials?

In the field of PCB materials, "high-frequency and high-speed laminates" are often mentioned together. However, delving into their design cores, the two have different emphases on key indicators such as common thickness, copper foil roughness, thickness tolerance, and dielectric constant (Dk) stabil
