Laser Marking on DC-DC Converters

A DC-DC converter drives electrical components in vehicles such as the headlights, wipers, and audio system by converting stored high voltage to a low voltage direct current.

Electrical components in vehicles require more and more power, resulting in a need for increased power capacity and a compact, lightweight design.

Laser Marking on DC-DC Converters
A / B
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.
