If you are looking for a quick and cost-effective way to get small holes drilled in almost any substrate, you have come to the right place.
Potomac Photonics has the capability for precision laser hole drilling as small as 1 micron with submicron positional tolerances in a variety of materials such as polymer, metals, ceramics and glass. Our engineers will work closely with you to fully understand the requirements for your micro-holes (e.g. materials, part thickness, desired feature geometries, taper, etc.) and recommend a process that will satisfy both your prototyping and production needs.
We have extensive experience partnering with medical device, biotech, electronics and alternative energy (solar) companies, helping them develop tailored processes to tackle some of the most challenging micro hole drilling requirements in their industries.
Applications such as leak testing, probe card drilling, microfluidic device fabrication, and micro-holes for catheters are just some of the thousands of micro hole drilling projects that we have successfully completed.
In addition to laser systems, we have micro-CNC and micro-drilling systems that are capable of drilling micro-holes through extremely thick substrates with high precision.

- Angled and shaped holes
- High speed drilling processes
- Material thicknesses from very thin films to several millimeters
- Multi-axis micro-hole drilling systems
- Rapid turnaround on prototyping and production projects
Materials Potomac Can Micro-Drill
By virtue of being part of the Goodfellow group, we have access to a vast catalog of materials that we can drill micro-holes into, such as:

Specific Micro-Hole Drilling Applications
- Micro hole drilling for probe cards
- Pinholes for photographic applications
- Leak test holes
- Catheter hole drilling
- Fuel injection components

We have a full range of small hole drilling capabilities and are continually developing new ones.
In addition, our high precision motion system can achieve extremely tight pitch and positional tolerances.
We can provide rapid turnaround on prototyping projects and have the facilities to run large production projects.
We also carry or can procure many materials quickly from our list of qualified suppliers.

Also From the Goodfellow Group
Achieving consistent micro-hole quality depends as much on the substrate as the process. Goodfellow offers metal sheet, polymer film, and ceramic plate in tightly controlled thicknesses and tolerances, ready for micro-drilling.
Source your drilling substrate from Goodfellow.
Hole diameter, roundness, wall quality, and subsurface integrity can be independently verified through Goodfellow’s ISO 17025-accredited materials testing division, using SEM imaging and dimensional analysis.
Validate drilled parts before integration into your assembly.
