Laser drilling is the process of repeatedly pulsing focused laser energy at a material, vaporizing layer by layer until a thru-hole is created. This is what is called a “popped” or “percussion drilled” hole. Depending upon material and material thickness, a “popped” hole could be as small as 0.002″ in diameter
Laser drilling is in widespread use throughout many industries, but especially in aerospace, automotive, electronics, medicine and electronics (especially in the semi-conductor industry). Laser drilling is particularly suited to low batch manufacturing and also for use in prototype designs (where expensive tooling costs can be eliminated). Traditional drilling techniques find it hard to replicate consistently the quality required in larger quantity batches, but with laser drilling every production piece is 100% perfect every time.
