Laser Hole Drilling Machine

The diameter of these holes can be as small as 0 002 50 μm.

Laser hole drilling machine.

The quality requirements are very high for micro drilling in particular. 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. Here is a selection of applications done with this technology in both the medical as well as the semicon packaging field. If larger holes are required the laser is moved around the circumference of the popped hole until the desired diameter is created.

The drilling time must be short enough so that laser drilling can compete with conventional drilling methods edm and punching. Critical items to consider when planning a hole drilling project include the diameter of the hole the thickness of the material the shape of the hole edge quality of hole desired taper of hole and center to center pitch of the holes. Lasers can be used to drill holes in many different applications across all industries. For through holes in small workpiece thicknesses single pulse processes can be used.

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. For large diameters trepanning drilling a combined drilling cutting process or the multi pass method are used. For thicker materials percussion drilling is first choice and with which the required depth can be achieved by applying several laser pulses. There are four main requirements which high precision drilling with lasers must meet.

Potomac is continually developing and adding new hole drilling processes to our facility. Compared to other drilling methods lasers offer superior speed and precision while lowering operating costs.
