Designing boards that fold like origami into wearable medical tech. Ensuring that complex designs can be produced efficiently

For localized, extreme heat sources (like RF power amplifiers), a solid chunk of copper—a "coin"—can be press-fit or bonded directly into a routed slot in the PCB. This provides a direct, metallic thermal path from the component package to an external cold plate. Mitigating Thermal Stress

For complex, tight enclosures (like wearables or aerospace hardware), integrate rigid-flex zones to eliminate bulky wire harnesses and connectors, increasing overall system reliability. For localized, extreme heat sources (like RF power

Keep differential signals closely coupled, matched in length, and symmetric. If a differential pair must navigate an obstacle, introduce length-matching chicane bends immediately at the site of the mismatch to avoid phase skew.

Unused portions of a via act as resonant stubs that destroy high-frequency signals. Implement back-drilling or use blind and buried vias to eliminate stubs on signals exceeding 5 Gbps (e.g., PCIe Gen 5/6, USB4). 2. Power Integrity (PI) and Decoupling Networks

Microstrips (outer layers) offer faster propagation speeds but are highly susceptible to electromagnetic radiation. Striplines (inner layers sandwiched between ground planes) provide superior electromagnetic shielding and tighter impedance control.
