Impedance Controlled PCB Manufacturing: Design, Testing & Supplier Guide
When a PCB carries high-speed signals, impedance control is not simply a routing preference—it is a manufacturing requirement. A reliable impedance controlled PCB requires a defined stackup, controlled dielectric thickness, trace geometry, copper structure, validated fabrication tolerances, and TDR verification against the customer’s target impedance. For engineers and procurement teams, the key question is not […]
