To produce an insulated track on a base material such as FR4 with a fully coated surface, the LPKF ProtoLaser U4 forms insulating laser channels on both sides of the track. Any geometric shapes can be generated in this manner. Due to the high precision achieved, this laser system is also ideal for RF applications and digital circuits.
