With the advent of new and high power plus lower cost UV lasers there is greater adoption of cutting of materials like printed circuit boards. This boards may be produced from fiber glass materials like FR4 or for thin flexible circuits they may be fabricated from polyimide or kapton. This process can now be handled easier and at higher throughput with lasers. Previous issues like jutting metal tracks can be minimized and there is minimal charring or heat affected zone. This provides a new method to the industry and is especially useful for low volume, high mix production and also for prototyping or engineering production as there is no need to invest in making mechanical die sets. As the laser is far more stable and durable then mechanical punch or cutter it is easier to ensure long term good product cut quality. And the laser can be programmed easily to cut infinite patterns so there is no mechanical die making cost and lead time is almost instantaneous.

With thicker materials like FR4 high power UV laser can cut thicker boards with minimal charring and HAZ. As laser cutting does not induce mechanical stress or disturbance compare to mechanical cutting, drilling, routing and other contact type methods, path can be cut nearer to active areas besides reducing board thickness thus shrinking PCBs. Other advantages are no constrain on board complex shapes, less likely manufacturing defects, easier fixturing and lending the process to automation.
