PCB Applications
Application-specific PCB design guidance and material selection.
PCB design requirements vary dramatically by application. A Bluetooth IoT sensor and a 77 GHz automotive radar module are both “PCBs” but share almost nothing in common regarding materials, construction, tolerances and quality requirements. This page links to application-specific guidance that covers the PCB construction decisions relevant to each application domain.
High Frequency & RF
Antenna feeds, filters, low-noise amplifiers, power amplifiers, radar front ends and communication transceivers operating from hundreds of MHz through millimeter-wave bands. Materials: Rogers 4350B/4003C, PTFE. Controlled impedance, ground plane integrity and transition optimization are critical.

High Speed Digital
PCIe Gen 4/5, DDR4/DDR5, USB 3.x/4, 25GbE/100GbE and AI accelerator interconnects. Low-loss laminates (Megtron 6/7), impedance control, length matching, via optimization and copper roughness specification determine channel performance.
