For the subsequent production process, the coating at the end of tubes has to be removed without any residues. Brushes or peeling processes quickly reach their limits at precision, wear and damage the part itself. The SLCR process is able to remove different organic layers completely without any problems. Metallic protective coatings will not be damaged.
Because of its compact building method with minimum employment of material and fully automatic manufacturing, flat cables (FFC, exFC, FLC) are applied in many industries. For the attachment of plug connections, active and passive components, it is important to remove the isolation in certain areas. With SLCR laser it is possible to free these contact points, even on miniature flat cables! Due to the laser treatment a precise positioning and a clean de-coating takes place. The connection can be made without mechanical reworks. The flat cable itself will not be damaged.
To protect electronic components from aggressive atmospheres, circuit boards are coated with a parylene or other protective paints for example. The problem is that even contact points – like bond pads – are coated. A masking of these certain areas is very difficult and is very work-intensive. Simply by decreasing the laser's pulse velocity, the coating will be removed in this minimal area. The metallic surface is clean and can directly be adhered in the following step.
In the field of rim production or rim painting, it is necessary that the calotte is clean and remains free of lacquer. The mostly used method for keeping this area free of paint is the so-called masking. Balls or plugs are put inside the holes to protect them from the coating. Due to the SLCR method of de-painting rim calottes there is no need to cover the holes any longer! The masking and de-masking process is eliminated and the calotte is de-painted without any residues. Even the surrounded areas where the paint should stay will not be affected. The transition from the area free of lacquer to the varnished area is qualitatively superior to the ordinary masking method.
In using chemical stripping or mechanical abrasive blasting processes, you always have a huge amount of hazardous waste which is very expensive to dispose. The SLCR process, with its especially developed SLCR-diagnostics, offers a totally new user-friendly and environmentally friendly alternative for the automated removal of paint systems from composite surfaces, regardless of the colour and structure. With the Airbus, Boeing, Eurocopter and other approved SLCR processes, layers can be removed for the first time either selectively – just to the primer - or completely – down to the substrate - without material damage.
