Drilling blind vias with lasers has become more and more popular over the past three years as PWB fabricators and OEMs recognize the benefits of a process that has high throughput, is versatile with materials, has a fairly large process window and requires little to no changes in their existing manufacturing line. Laser drilling systems have improved in throughput over the past two years and as fabricators develop close working relationships with the laser system suppliers, better laser drilling systems emerge. This paper will discuss a laser drilling system that is a direct result of input from fabricators around the world. Details will be provided on compatible materials, and processing speeds.
