The laser technique is a non-contact and non-abrasive process, no use of chemicals or blasting media are necessary, we see a reduction in waste, automation is easy and it’s very safe.
Often not the complete surface has to be cleaned, but only certain spots on that surface. Imagine you only have to remove rust on certain spots on a weld or that you only want to clean the rivets on the body of an airplane. That’s where spot repair comes in and because of the 2D-scanners in the optic of our laser systems, circles can be created at once, which speeds up the complete process drastically.
For this, the PCB’s have to be completely clean. During the production process, flash is introduced on the sides of some of the components. Laser cleaning is able to remove this flash, before it enters the tinning bath. Due to this, the quality of the PCB is improved and stabilized, making sure every PCB has the same properties over and over again.
