- A: 2D code and character string marking on PCB
- Glass epoxy PCB marking must be damage-free to prevent particle generation on photo-resist removal.
- B: Serial number marking on the case cover
- Conventionally, affixing labels to the case was common, but laser marking is becoming more popular to reduce costs and simplify design changes.
