Laser ablating busbars

Laser ablating busbar coating

Busbars are made of metal, typically copper or aluminium, and are used in electric vehicles for power distribution and to connect high or low voltage equipment in battery banks. They conduct a large amount of electricity and have an epoxy coating for insulation. This coating must be partially removed so that the busbars can electrically connect to other components in the vehicle.

Unlike mechanical methods, laser ablation is contactless, without ablation or loss of metal, and with very little downtime or tooling needed for any changes.  A galvanometer scanner passes the laser beam over the required area; in this way, two lasers can be used to process all sides simultaneously while leaving the metal undamaged.

Removal rates depend on the type and thickness of coating, as well as the coating method (cross layer), but there is no material loss (cost of copper or aluminium) when a CO2 laser is used.
