SMD LED Polarity Identification
The positive/negative electrode of LEDs must be in the same direction as the positive/negative electrode of the PCB. SMD LED polarity is marked by:
- 1. The negative electrode of the LED is marked by the green color blocks.
- 2. The negative electrode of the PCB pad is marked by a color strip.
- 3. The negative electrode of the PCB pad is marked by a silk screen sharp corner.
- 4. The negative electrode of the PCB pad is marked by a silk screen 匚 frame.
