Laser drilling is the process of creating thru holes referred to as popped holes or percussion drilled holes by repeatedly pulsing focused laser energy on a material.
Laser hole drilling machine.
Lasers can be used to drill holes in many different applications across all industries.
One of the process in stent manufacturing is hole drilling of the tube holder.
Time quality flexibility and reproducibility.
The quality requirements are very high for micro drilling in particular.
Here is a selection of applications done with this technology in both the medical as well as the semicon packaging field.
There are four main requirements which high precision drilling with lasers must meet.
For thicker materials percussion drilling is first choice and with which the required depth can be achieved by applying several laser pulses.
Laser drilling is a non contact process that uses focused high energy density light to ablate material and drill holes in a wide variety of materials.
If larger holes are required the laser is moved around the circumference of the popped hole until the desired diameter is created.
The diameter of these holes can be as small as 0 002 50 μm.
The drilling time must be short enough so that laser drilling can compete with conventional drilling methods edm and punching.
Compared to other drilling methods lasers offer superior speed and precision while lowering operating costs.
Potomac is continually developing and adding new hole drilling processes to our facility.
