5 High-Freq PCB Design Techniques

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.

The etching procedure of the external circuit on the PCB substrate

The common process for processing printed circuit boards utilizes the pattern plating method to preserve the graphic portion of the circuit, while the full board copper plating process involves copper-plating the entire board. Etching quality, equipment adjustment, and maintenance are crucial in achieving high-quality etching outcomes in PCB production.
