Laser Marking on Inverters
Inverters convert stored electricity from DC to AC and supply AC to the motor. Because motors rotate over a wide angle while a vehicle is operated, inverters must meticulously control the supplied electricity.
- 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: 2D code marking on cooling device
- Marking a 2D code on the cooling device makes it very easy to ascertain the device specifications.
- C:序列号标识在箱盖上
- Affixing labels to an inverter's case is common, but labels are expensive to produce and can't accommodate design changes well. Laser markers don't incur running costs and are very easy to adjust.
- D: 2D code and character string marking on aluminum cast parts
- Cast aluminum cases can vary in size depending on product tolerances. It's important to have a marking system that can compensate for these size changes, otherwise you run the risk of defective, out-of-focus marks that aren't readable.
