Laser Technology For The Aerospace Industry

Battery Cells Ultrasonic Wire Bonding Preparation

Ultrasonic bonding requires a perfectly clean surface to ensure high strength and low resistance wires and interconnects.

Laser cleaning is the ideal technology to prepare cells for bonding, as it eliminates chemicals from the cleaning process and speeds up surface preparation.

Cooling Plates Cleaning & Texturing

Cooling plates and tubes used for thermal transfer in batteries need to be cleaned to obtain a strong bond with thermal adhesives. They can also be roughened to further increase bond strength.

• Laser cleaning removes contaminants that interfere with the adhesive bonding process, resulting in a stronger and more durable bond.
• Laser texturing creates a rough texture that increases the contact area between thermal adhesive and substrate. It improves bond strength and can potentially improve thermal transfer.

Housings Surface Preparation

Battery and e-motor housings sealed with liquid gaskets need surface preparation to maximize the adhesive’s strength and ensure the best possible environmental protection.

Laser cleaning maximizes the surface free energy available for sealing by removing all types of contaminants, including oxides, dust, and grease.

Bipolar Plates Cleaning & Texturing

Metallic bipolar plates used in hydrogen fuel cells can be cleaned and textured to ensure that fuel cell stacks meet the highest quality requirements.

• Laser cleaning removes oxides, oils, dust, and other contaminants from plates before they are coated and assembled in a fuel cell stack.
• Laser texturing creates a microtexture on the plates’ surface. This improves adhesion before coating processes like thermal spray coating, e-coating, and other protective coating.
