3. Solder mask color: There are many colors, you can choose according to your own requirements, generally green.

4. Silkscreen color: The color of silkscreen fonts and borders on the PCB is generally white.

5. Copper thickness: The thickness of copper is generally calculated scientifically according to the current of the PCB circuit. Generally, the thicker the better, but the cost will be higher.
