1. Keep high-frequency signal traces short to minimize interference and enhance device performance. 2. Straighten wire leads with gentle bends to reduce emissions and interference in high-frequency circuits. 3. Isolate ground wires for digital and analog signals to prevent interference and voltage differences. 4. Avoid wiring loops and minimize loop area in high-frequency signal traces. 5. Reduce via usage to increase signal speed and minimize data errors in high-frequency circuit boards. 6. Enhance power supply integrity by incorporating high-frequency decoupling capacitors at integrated circuit block pins.
